Sentimental Journey Fly-In
Mike Meador, Bob’s friend and successor in the R&B engine building business, travelled to the Sentimental Journey fly-in in early June. This event is at the “birthplace of the Piper Cub”, William T. Piper Memorial Airport (KLHV) in Lock Haven, Pennsylvania. Virginia-based pilot and instructor Mike Brown flew Bob’s Patrol to the event, and repeat-builder Tim Weaver was on hand with his blue and white Bearhawk LSA. The event included some spectacular drone shows and activities, and Tim’s airplane made it into the local news coverage.

First Flights
Congratulations to Walter Bolan on the first flight of his Bearhawk 4-Place, N789CB, in Oregon. His empty weight came to 1487 with a 540 and Oratex covering.

Carlo Cilliers completed his scratch-built Bearhawk Patrol N37BP in Maryland. Todd Stock reported on the forum:
Build ran September 2023 (plans in hand) to 31 May 2026. Mods included:
– Wet wing
– Overhead flap actuation (elimination of cables, etc.)
– Electric servo-in-horizontal-stab elevator trim
– Ventral fin added to counter yaw hunting seen on another Patrol
– Two piece clamshell cowl with plenum
– Heavily modified seat design
Test pilot reported well behaved airplane with light roll forces, in-the-groove yaw performance, and solid pitch authority through stall series. Comfortably moderate flap deployment and retraction forces and both clean and flap stalls were drama-free with no tendency to depart or other adverse behavior. CHT were higher than desired, but that reflects the baffle system and cowl sealing still being refined. And that was about it. Strut fairings and a bunch of other minor stuff (including final cowl paint and some work elsewhere to level/buff) to go, but it looks like Carlo can make Oshkosh this year.


That’s Carlo in the middle, half way in the door.

You might have noticed that red is a popular color for 2026 completions, both in this issue and the last! Please send us your updates for the next Beartracks, even if your plane is not red!

Speaking of not red:
Scott Sarkinen flew his Patrol N431NS in Amboy, Washington.
Scott says: “First flight on Saturday May 9th 2026 with my Bearhawk Patrol, Lycoming 0360, Hartzell Trailblazer prop, plans build took 6 years and 2 months, little over 4,000 hours, weighed in at 1153 lbs.
Flew great except a slight heavy right wing.”

Cam Lawrence sends this photo of his Bearhawk 4-Place C-FWGV, which he operates out of his home strip, near Cooks Creek, MB, Canada. Cam is part of a group of builders including George Huntington who have completed three Bearhawks, with one more to go. Cam’s plane is built from plans number 815. He plans to have the plane at Oshkosh next year and I can’t wait to get a few dozen more pictures of it!

Mark Scott from Connecticut wrote in to say, “Just thought I would let you know I passed 1000 hours on my Bearhawk recently. I wonder how many Bearhawks have made it that far and who has the most hours on each model. Any idea?
I don’t have a very good idea unfortunately. Our plane N303AP has around 1400 hours. Write in if you know of any specific high-time Bearhawks. Mark started a discussion on this topic a couple of years ago but it could benefit from some updates! https://bearhawkforums.com/forum/bearhawk-general-discussion-news/90106-total-hours-summary

Rod Smith in Colorado started a forum thread about flight testing after he added vortex generators. Rod says, “Last winter I completed all the Phase 1 flight testing cards before I installed VGs. The only flight tests I redid after installation were the full stall series and landing and takeoff distances which all definitely improved. I have wondered how the VGs might impact other speeds such as Vx, Vy, and best glide. Needing to complete my Aircraft Operating Handbook, I decided it was time to redo the climb and glide speed tests. Early January provided a high pressure system with very still air for a few days. Winds aloft ranged from calm to 5kt. There was no detectable lift or sink flying early in the cold mornings. I spent three hours over two days testing at 5kt intervals. Testing was done at 2400#s 17.6″ CG. Interestingly Vy and Vg both decreased, Vg from 75 to 70. Vy from 65 to 62. Climb rate at 60 and 65kts was within 10 fpm so I tested at 62 and it was 25 fpm higher. Vx remained the same at 55k. I feel that these were accurate results, the air was very stable and I was able to hold the speed +/- 1kt. I feel like the results were quite a bit more reliable than my earlier testing which was done with less stable air and I had more trouble holding the exact speed. Did the VGs change Vy and Vg? Don’t have enough information to know, may have just been better testing. I found that flysto.net provided more accurate altitude numbers at 1 second intervals than I was able to record as the timer hit 60 seconds.”

Bearhawk builder and long-time operator Russ Erb has been writing some technical papers based on his Bearhawk experiences, which long-time Beartracks readers will remember. Russ has posted three papers on his website at http://erbman.org/technicalpapers/technical_papers_index.htm (scroll down to the bottom for the most recent three).
Russ says, “Two of the papers, ‘Takeoff Chart Development for a Homebuilt Airplane by Numerical Simulation’ and ‘Simplified Takeoff Model for a Homebuilt Airplane,’ were started as an article for the Trailing Edge (Russ’s newsletter), but grew to a technical level that made it suitable for submission as a technical paper. The one article was split into two papers due to AIAA’s presentation time limits. These papers cover the development of two takeoff ground roll distance models for my homebuilt Bearhawk, which as a homebuilt doesn’t come with performance data. I answer the question of if I think I could safely fly my airplane out of Lake County Airport (Leadville CO), the highest elevation public use airport in the lower 48 states. Will I actually try it? That would depend on having a strong reason to actually fly the long distance to Colorado.” We’ll have to ask the Blue Bell Ice Cream folks to open an outlet in Leadville so that Russ’s numbers can finally be validated. The third paper “Measuring In-Flight Deflection of Cable Actuated Flaps” started as an article previously published on the Trailing Edge, and was re-written as an AIAA technical paper.

Speaking of Bearhawks in the news, there have been some Bearhawk sightings in the EAA’s Sport Aviation magazine. We saw a blurb about Brooks Cone’s Bearhawk Patrol and in our last Beartracks issue we failed to mention Charles Albritton’s article in the October 2025 edition about a really-quick-build Bearhawk Five project in Brazil. Any time you see good Bearhawk coverage in a magazine or publication, take a moment to write the editor and thank them for it!

You might have also seen Bob’s advertisement in Sport Aviation:

Have you ever found yourself wondering how to build a Bearhawk spar? If you have, there are some fantastic forum threads on the topic, including this recent discussion where Patrol builder Stan Timmerman does what he often does, replying to his fellow builders with very detailed technical answers, and color 8×10 glossy photographs with circles and arrows. Shout out to Stan for helping build such an amazing useful archive!

Are you interested in 3-D Printing? We’ve created a new category on the Bearhawk Forum website where builders can share files and ideas for tools and parts. Nev Bailey from New Zealand shared a clever printable cubby that turns the space under the front seats any of the side-by-side Bearhawks into a useful storage bin. Several builders have posted cool ideas.

Frank Johnson’s Bearhawk LSA N964BW
Frank writes:
My impressions of the Bearhawk LSA after 20 something hours of flight!
It’s been a long 5 years of building, even though that’s the fastest I’ve completed a build yet. Not sure if that’s a testament to the kit or my growth as an EAB builder, Ha ha.
Now, I’m a low time pilot and doing my best to describe the experience, so keep that in mind. My flight experience is limited mostly to Experimental aircraft, Van’s RV6(200hrs), some Cub and Champ time, with 600 plus total time. Most recently in a Rans S7s(300hrs), Baby Ace (55hrs),and Aeronca 65TC(45hrs).
First flight was uneventful even though the plan was to do a few crow hops, it was off the ground quickly and I left power in too long for just a hop. So, around the pattern we went. There were no bad tendencies, no heavy wing, tracking was straight. Touchdown was a bit fast as planned since I hadn’t done any stall work. Approach was around 50 mph, once over the threshold and low I let the speed bleed off and mains touched, the tail settled down shortly after that. 
From the beginning my plan was to do the task based in phase one using the EAA test cards. With the LSA several of the test are not applicable, no flaps, fixed pitch prop, no EGT, CHT. Its pretty simple plane.
Sometimes working on several test in a day, as many as three flights a day. Almost like a job, yikes.
Stalls are very subtle, power off around 30mph indicated it kinda mushes down as long as the ball is centered. With some yaw a wing drops, but nothing drastic, and recovery is instant when dropping the nose ever slightly with a touch of power. With this, approach speed is comfortable around 45mph. 
Slips! Now they are impressive! Its like an elevator ride when doing an aggressive slip. Then soon as you straighten out the sink stops. What an awesome tool for short field landing. I’ve even come in fast on approach and slipped in ground effect to bleed speed. 
Departures are short! Loaded, full fuel, off the ground in no wind is around 250ft. Remember, I’m pretty much at sea level 380ft field elevation. I’m certain this can be much shorter but being over pitched, 44″, in the prop and only make 2250rpm static and 2550 at full throttle. Current rate of climb is 900-1000fpm depending on load and density altitude. Current WOT airspeed is 125mph+- at 2550rpm. I’ve seen 135mph plus, but it was rough air and not sure how accurate.
I’ll be changing the prop to a pitch of 38-40″ later. Target rpm range is 2600 static and 3000wot. My personal goal is sub 100ft roll departure and 1500-1800ft roc with economy cruise100mph and WOT of 125mph.
My LSA is basic, O200 with a Performance Propeller. Empty Weight 785lbs. No Alternator, so I have what’s called a Total Loss Electrical System powered by an EarthX etx680c. With an AV30e, Trig-TY91 com radio and Starter. (With no engine driven Charging system the plane is not required to have ADS-B out for operation under Class B veil.)
Mechanical oil temp, oil pressure gauge, tach, and back up airspeed indicator.
The biggest challenge has been finding accurate oil temp and pressure gauges. I’ve gone thru a few. So much that I called GRT avionics and purchased another EIS4000. 
The calculated hourly draw on the battery is now 600 milliamps (approximately 7.2 watts), this isn’t counting transmitting on the Trig or what the starter uses. The AV30E and EIS4000 monitor system voltage and is displayed continuously. This allows many hours of operation without recharging the battery, estimate is 8 plus hours. 
In preparation for long cross country trips I’ve acquired and 30watt solar panel that has a controller, there are settings for different battery types on said controller. This will keep the battery topped off and allow charging my phone and iPad. It will be mounted in the left rear corner of the skylight, dimensions are 14″ x 14″ and weight is 1.6lbs. 
I’m looking forward to flying adventures in the LSA, its going to be a great Day VFR traveling machine.

Westbound with the Abels from Indiana in the Bearhawk 5

Source: 2025 Q4 Beartracks, Elliot Abel
By late summer 2025, the hangar finally grew quiet. The last safety wire was twisted, the final cowl screws snugged down, and the smell of fresh paint on aluminum lingered faintly in the air. After years of cutting, riveting, wiring, and dreaming, our Bearhawk 5 (N847EM) stood complete.
On August 4th, the Lycoming IO-540 came to life for its first flight on our airplane. Over the next several weeks, my wife Melanie and I carefully flew off the hours. Built in 2 years, 10 months, and 19 days by the two of us, with assistance from Dale Barkley, the Bearhawk was smooth and strong—eager to stretch its wings. By mid-September, with 60 hours on the engine and airframe, it was time to point west toward the mountains, the desert, and the famous High Sierra Fly-In.
Our plan was to have at least 50 to 75 hours on the airplane before heading out west, just to build trust between pilot and machine. But as any builder knows, airplanes have their own schedules. A mechanical gremlin crept in, and we found ourselves waiting nearly two weeks for parts. Once everything was sorted, we added a few more solid hours and felt confident.
When we finally loaded the airplane, it was me, Melanie, two folding e-bikes, and every piece of camping gear you can imagine. Even so, we were still under gross weight—about 2,800 pounds against the 3,000-pound limit. The Bearhawk took it all in stride, eager for adventure.
Our first destination was Fairview, Oklahoma, home of Bearhawk Aircraft kits and builders assist. We wanted to meet the team—Virgil, Peter, Ty, and the rest—and see where these incredible airplanes come to life.
We parked right next to the build-assist facility and joined the crew for lunch and a tour. By pure luck, Erin and Paul were en-route in their Bearhawk 5 as well, so we stuck around to meet them. Seeing two Bearhawk 5s side by side was something special—a milestone moment for the community and for us.
Melanie reminded me that we still had to make Albuquerque before sunset. I don’t fly single-engine at night anymore, so we pressed on. The first leg from Indiana to Fairview had been 4.3 hours, and the next to Double Eagle II (KAEG) near Albuquerque was 3.8. We landed just after sunset, with just enough light to feel safe—that warm glow of accomplishment mixed with fatigue and satisfaction.
The next morning, we turned west again. Our stop in St. George, Utah, came with a healthy 30-knot headwind right down the runway—a perfect chance for a quick refuel and lunch before the desert turbulence built.
By nightfall, we tied down at Reno-Stead Airport, home of the famous Reno Air Races, but spent the night at the Peppermill Hotel Casino. The next morning, we were ready for the real goal: to join the early arrivals at Dead Cow Lakebed, home of the High Sierra Fly-In.
We lifted off from Reno-Stead and flew out into the desert, touching down among the first ten aircraft to arrive. The Dead Cow dry lakebed is vast—miles of hard-packed clay surrounded by mountain ridges, shimmering under the Nevada sun. It’s desolate, but breathtaking.
We set up camp beside a few friendly camper folks and waited for the others to arrive. Before long, Peter Brown from Bearhawk landed in the factory Patrol, and the little camp began to grow into a village.
Later, Harry Beaupre invited us to join him for a local intro flight in his Kitfox. He led us over Mountains, across BLM land, past geysers and ridgelines—showing us how free you can feel when the world below is open country. Landing on mountaintops and short one-way strips was surreal—a mix of exhilaration and respect for the terrain.
But as the West often does, the weather turned. Rain began to fall, and it didn’t stop. In just 24 hours, the dry lakebed received an inch of rain—out of its usual seven inches a year. The once-dry surface became a sticky mess of thick clay. Every step added a pound of mud to our shoes. We didn’t bring boots, so we trudged carefully between camps, laughing at the absurdity of a “High Sierra Fly-In” that had suddenly turned into a lakeside retreat.
What stood out most was the people. Fellow pilots and campers offered us food, warmth, and even space inside their RVs to dry off. The sense of community was unmatched—it reminded us that aviation isn’t just about airplanes; it’s about people who share the same stubborn passion for flight.
When the skies cleared, the desert dried fast—faster than anything we’d see in the Midwest. Attendance was lower than previous years, but still remarkable. We saw everything from Mark Patey’s Pilatus to homebuilt experimentals that had crossed the country just to be there.
Each morning, Melanie brewed coffee and cooked a small freeze-dried meal on our Jetboil stove, a little luxury that felt like a feast. Around lunchtime and dinner, the offers rolled in—fellow campers inviting us to share grilled meals and stories.
Peter zipped around on his Onewheel, while Melanie and I explored the lakebed on our folding e-bikes. Transportation is essential out there; what looks close in the desert is often miles away.
The Bearhawk 5’s enormous cargo space made it all possible—two e-bikes, a cooler, solar panels, a tent, and still room to spare. Even Peter’s Patrol carried more than most pilots would believe: a Onewheel, generator, cooler, and more—proof that these airplanes are truly made for adventure.
Once the mud hardened back into its desert crust, the flying resumed. We explored the surrounding BLM lands, landing on dirt roads, dry washes, and even a stretch near a hot spring. It’s the kind of flying that feels like freedom itself—the kind that just doesn’t exist back home in Indiana.
We wrapped up our time at the Fly-In watching the STOL Drag competition, a crowd favorite. It’s an amazing event because you quickly realize it’s not about money or machines—it’s about skill and heart. “Fly what you bring” was the unspoken motto, and it fit perfectly.
When the event wound down, we said goodbye to Peter as he headed back east. Melanie and I decided to keep going west—wherever the sky took us. Our next stop: Shelter Cove, California.
The flight was stunning—from desert to mountains to the blue sweep of the Pacific Ocean. Shelter Cove is a tiny coastal town with a runway right on the shoreline, a picture-perfect landing spot. We checked into a small Airbnb, pulled out the e-bikes, had a drink at the local pub, and watched the sun sink behind the lighthouse. It was one of those perfect aviation days you never forget.
The next morning, we aimed for Napa Valley. Melanie had never been, and we couldn’t resist. The weather was IFR, but the Bearhawk 5 was built for it: dual Garmin G3Xs, a GFC 500 autopilot, and a GTN 650 navigator. We filed IFR and shot the ILS into Napa, just like we do for our day jobs.
Once on the ground, we unfolded the e-bikes again and spent a couple of days tasting wine and exploring the valley. We even brought home more than a few bottles .
After Napa, it was time to turn east. With 74 gallons of fuel and 300 horsepower up front, the Bearhawk cruised at 150 mph, making the trip from the Pacific Ocean back to Indiana in just four legs.
The airplane performed flawlessly, carrying us over mountain ranges, plains, and cities—a rolling tapestry of America at times over 10,000 feet. It was an amazing trip, one we’ll never forget.
Next year, we plan to do it all again—maybe with a camper this time. But no matter what, the Bearhawk 5 will be there, ready to go wherever the horizon leads.
For us, this wasn’t just a flight. It was a proving run—a celebration of what homebuilders can create and what aviation makes possible. From the heart of Indiana to the High Sierra desert to the Pacific coast, we saw America in a way only pilots can.
As we touched down back home at Terre Haute (KHUF), now with over 100 hours on the airplane, we knew one thing for certain: the Bearhawk 5 had earned its wings—and a permanent place in our hangar.

Stephen Ingram’s Bearhawk 4-Place N789WM First Flight in Texas

Source: 2025 Q3 Beartracks
N789WM first flew on August 5th, 2025. You can read about my experience with the first flight of my newly built Bearhawk aircraft, following my transition training in North Carolina, on the Bearhawk Forums. In summary, despite careful preparation, the initial attempt was aborted due to a fouled spark plug, and the actual first flight revealed a misconfigured RPM sensor, leading to false high-RPM readings and considerable anxiety mid-flight. Minor issues like a lost fuel cap and unfastened tailwheel chains were discovered post-flight, reinforcing the importance of a thorough punch list and better planning. Ultimately, the flight was successful and educational, and shows the value of preparation, clear checklists, and learning from unexpected scenarios.
Since that first flight, there has been ongoing maintenance, discovery, and tweaking. After the first couple of hours, I was struggling to keep my cylinder temperatures within a reasonable range, and having to level off and build speed to keep the rear cylinders below 430F. I was very concerned about glazing before the rings had a chance to seat on the brand new engine. After having a friend look over my engine, and baffles, we realized a couple things: My front air dams seemed too high in his experience; and I hadn’t ever really gotten back around to sealing all the holes in the baffling. He also has a O-540, but in an RV, and he said he ended up without air dams at all. He reasoned that if my temps are high, I could remove the air dams altogether and the worst case they are too low and I have to put some back. I agreed, and drilled off the front air dams.
Next, I set about diligently and thoroughly finding every crack of light shining through the baffles and sealing it with RTV. I prefer the gray RTV, as the color blends in well with the rest of my engine. This ended up using almost an entire tube of RTV. But I felt confident that this would help address the heat issue. The main is to get that pressure differential between the upper and lower engine great enough to pull air though the cylinder fins, and it doesn’t take much, but any hole in the baffling is lost opportunity to carry away heat, and pressurizes the lower cowl.
The next flight the CHT’s were much better, and increased much more slowly. Success! But now, the next problem…my oil cooler is front mounted with a scat hose leading to a duct over the cooler to put the air through it. Lots of gaps around the fiberglass duct against the face of the oil cooler. Get another tube of RTV…
I also struggled with high CHT’s around #5, and a common solution for this, depending on how your cylinders are cast, is to build an air duct to shunt air around the backside of the cylinder. This called for breaking out the rivet gun and some scrap aluminum and within a few hours I had a decent looking duct. This greatly helped even out the CHT on #5 to something close to the other cylinders.
My project was a stalled out project with a new engine that had been sitting for a number of years. I had borescoped the internals of the engine as much as possible, and it all looked pristine. However, in the last few hours, I have had a number of seals, O-rings and gaskets start to leak. If you have had your engine for a while, the internals are probably fine, but you should expect to go through a round of fly, find the leak, replace, fly, repeat etc. Many rubber and non-metal parts of an engine wear out over the years whether they fly 1 hour or a 1000 hours. This lead me to have a number of oil leaks, an intake leak, and a fuel leak, all within the last 10 hours. Nothing catastrophic, but annoying nonetheless.
Initially, my flight controls felt very “heavy” and the adverse yaw was over the top. Thanks to the forums, and some posts I found there, I decided to go back through my tail and take it completely apart and identify any source of friction. I found quite a few places that I could have done better the first time, and most of my friction was actually in the trim tab on the left side. The hinge would bind against the paint and the clevis pin was tight in the hinge. I sanded, reamed, polished and straightened the elevators relative to each other very carefully, and this removed almost all the friction in the pitch.
For the adverse yaw, I decided to check my aileron rigging again, and raised both ailerons about 3/8 inch reflexed, as many had reported this removed a lot of the adverse yaw. I also went back through my flap rigging and made sure they were exactly equal to the wing trailing edge, and got everything as straight as possible.
The first test flight after the rigging changes was noticeably better. Most of the adverse yaw was gone, but enough to still keep you on your toes, rudder-wise in the turns that is. My autopilot no longer complained about trimming while maintaining altitude much better. I still have a very slight right roll that I am hoping a little more attention to the rigging will alleviate, but if not, I will employ the “washer trick” under the heavy wing hinge.
I am thankful that we live in the experimental side of aviation, since it allows us to experiment and to have “experimental” avionics and tools to discover and address issues quickly and confidently. Without a good engine monitor, I would not have been able to tell exactly which spark plug had fouled on my first flight. Without continuous monitoring, I would not have realized that one of my CHT problems was a leaking intake gasket. I also want to emphasize how invaluable sites like the Bearhawk Forums, Savvy Aviation, and Flysto are if you are willing to share your engine and flight data. Using Savvy, I was able to analyze engine data and dial in on the intake leak. Using Flysto, I was easily able to identify pitot-static errors, and rewatch and critique my flying. And of course the Bearhawk forums are great for tips, tricks, and the comradery surrounding this excellent airplane type.
As of the evening I am writing this, I am at 17 hours, having a wonderful time flying, looking forward to seeing other Bearhawkers out there, and just found another oil leak.

Bearhawk LSA N456YA First Flight Report from Andy Bell

Source: 2025Q2 Beartracks, Andy Bell
Congratulations to Andy Bell on a successful first flight of his Bearhawk LSA, on May 3rd! He received his airworthiness certificate the day before. His DAR was Paul Dye, who you may recognize from his numerous contributions to the Kitplanes magazine.
The engine is a mid-time O-200D out of a Skycatcher, and the empty weight is 865 pounds with an empty CG of 11.26”. This is quite respectable considering the plane is well-equipped, with an Earthx battery, Skytec starter, Plane Power alternator, oil cooler, Vetterman dual muffler exaust, strobe and wigwag lights, a basic VFR panel with adsb in and out, Stewarts System paint, 8.50×6 tubeless Desser tires, and dual puck Matco brakes. The wings are polished bare aluminum. Flight testing has shown 125mph TAS at 2640 rpm. Andy has shared many more details on his build log website, https://eaabuilderslog.org?s=ABell

Spring 2025 Bearhawk LSA Update from Barry Neal

Source: 2025Q2 Beartracks, Barry Neal
I mostly scratch built the LSA over 4 1/2 years. I first flew it in April 2023 and now have 110 hours on it. I flew it to Lakeland last year. It has an O-200A with a Catto prop and Vetterman exhaust. It has 8.50-6 tubeless tires and Matco wheels and brakes. It will cruise at 117 mph at 2600 rpm and around 113-114 at a more reasonable and quieter 2500 rpm. It flies great with no issues. I keep it at Fulton Field SC66, a private field near Spartanburg SC. I have just recently retired and have more time now to talk to people and answer questions.

Congratulations to Paul for winning the Best Homebuilt Aircraft award! The convention was held in Middleburg, Mpumalanga. Paul’s Bearhawk has an Aerosport IO375 making 200hp, and an MT9B 3-blade prop, and a VFR Dynon-based panel. It first flew in October 2022. The photo to the right shows Paul on the left, and Jayson Van Schalkwyk of Berg Aero Works, the South African Bearhawk dealer. Jayson had arranged a display of the Paul’s plane, a Patrol, and an LSA at the convention.

Bearhawk Patrol N62588 First Flight

Source: 2025 Q1 Beartracks, Brooks Cone
I wrote an article last issue on a Patrol that I started in 2017 and am nearing completion on. I talked about the theme of efficiency, utility, reliability and maintainability that drove decision making of the build. At that time the FAA paperwork had been submitted for its airworthiness inspection.
I signed off the condition inspection on January 2nd, the FAA performed the airworthiness Inspection on January 21st and the first flight was on February 22nd. The Patrol has about 7 flight and 10 hours on her now as of this writing.
I knew that the FAA’s inspection of my Patrol would be broad in nature rather than detail oriented. I wanted and needed an inspection with detail, so I hired an A&P with IA in November to inspect it. The inspection lasted about 3.5 hours. With a mirror and flashlight in hand he looked at everything and wrote discrepancies down on a tablet. I studied what he did and how he “thought” as he looked around. At the end of it I had 75 items to fix, a builder tutorial of how to inspect, and a higher standard to rise up to. That was just what I, an untrained amateur who builds alone at home, needed. In the subsequent weeks as I worked on his list, I kept discovering my own items and so the number of items to fix nearly doubled. I am convinced I would not have appreciated a judgmental eye on my build if a DAR inspection
was combined with an evaluation for an airworthiness certificate. I suppose the way I had it done gave me a measure of protection from failure and confidence in more than just “passing”.
The first flight was done on Saturday morning, February 22nd. The temperature was 17F and it lasted about 40 minutes with the objective to run the engine hard for break-in. I’ve got good cabin heat, low CHT’s and very good oil temp control. My oil system has a shutoff valve to the cooler controlled in the cockpit. I have outstanding control of oil temp. The break-in schedule after the first flight was interrupted by my ADS-B performance report saying it’s inoperative.
My Patrol resides in mandatory ADS-B airspace, and so flights #2 and #3 were dedicated to making it operational. Break-in continued on Flights #4-7, providing 9 more hours on the engine.
When we break-in an engine the question we all ask is “Will it run too hot?” My CHT’s were normal from the first takeoff. With 65% confidence I say CHT’s were not hot because of time and care spent on crafting two firewall forward items – Sealing the baffling, and the design of the cowl exit.
Air that enters the top cowl is for engine & oil cooling. Air that leaks and dodges any cooling fins is wasted drag and reduces the pressure differential across the cooling fins, so I decided to plug them all up. A flash light in a dark hanger strategically positioned below the cylinders reveals all the leaks. Most of them are found around the base of cylinders. I have a friend at the airport. His name is Wayne. Wayne is a super inquisitive, and enthusiastic builder who is at the airport every day . I’m just kind of average but am further along so we help each other out. Life is better when humans collaborate. Occasionally Wayne uses good words that describe a situation. Three that come to mind are “Rat Hole”, “Sticktion” and “MVP”. Sticktion is the sticky friction we overcome when we initiate movement. After things get going, the stickiness of high resistance is reduced. MVP describes a part or assembly that is Minimally Viable…a Minimally Viable Product. An MVP is not pretty but gets the job done and keeps the build moving along. We’ll make it pretty later on.
Now about rat holes. Cars have rat holes and manufacturers don’t like them. My grandma’s basement fruit cellar had them. The average Lycoming baffling installation has rat & mice holes too. They are found in places like corners, at the cylinder base and inner cylinder baffle. Lots of air passes through them without cooling. When a rat hole is plugged, the cooling improves and drag is reduced. So I search out and seal up baffle joints and small stuff with ahigh temp silicone product called Permatex Ultra Black gasket maker. I think the black Permatex looks better than the red stuff but that works too. Some spots are difficult to reach, so I fill a small syringe with Permatex. A 12” piece of tubing pressed onto the syringe nozzle helps apply it there. Another tool I used was a tongue depressor.
My flashlight easily exposed four rat holes the size of my thumb. They got a piece of fiberglass impregnated with Permatex. I place plastic sheathing onto the top of my workbench, then put down a small piece of fiberglass cloth. I squirt some sealant onto the cloth then fold the top of the plastic over it so the sealant and cloth are sandwiched by the plastic. Then I press the sealant into the weave with a putty knife. It should be mess free. When the cloth is fully impregnated with sealant, I cut the patch to final size with scissors, remove the plastic and plug the rat hole by stuffing it with hemostats.
In conclusion, my Patrol is flying, I’m breaking in the engine, and have cool temperatures that I think is due to tight baffling, and the engine cowl design. Next quarter I’ll share how I incorporated the tunnel and cowl exit, and share with you how my engine break-in went.

Bearhawk 4-Place C-FZVW, Way Up North

Johnny Adams sends an update about his Bearhawk C-FZVW, formerly N1914M. His home base is CYVP, Kuujjuaq, Quebec Canada. To get there from the USA, start in central Maine, head north, and travel another 750 miles or so past the border!
He bought the plane in flying condition in 2013 and imported it from the USA. In 2024 he refreshed it with a 10-year overhaul, adding landing lights, ADS-B, top overhaul, a ground adjustable Sensenich prop, polished wings, and new seat upholstery. He had the panel completely redone with new avionics, and added a fresh paint job. The covering is Poly Fiber and the total time is now 300 hours.
The engine is a parallel-valve Lycoming O-360 A4M. It has a Vetterman exhaust with double heat shroud, and he has recently removed the vacuum pump. In the winter he installs 2500 Datum electric skis. Empty weight on Goodyear 26” wheels is 1294 pounds, and with wheel skis, 1389 pounds.
The first builder was Michael Moening, who used a factory kit.
