Wing Root Vents

I put Cessna vents in the leading edges because Bob says they work fine. In case anyone else want to use these, I thought you might want to know the original Cessna vent has to be modified. It is an easy modification and only requires

Correcting a Heavy Wing- The Washer Method

Source: 2006 Q4 Beartracks
The following info was developed by Jim Clevenger, owner & builder of the just finished Florida demo Bearhawk – plans serial # 448 (prototype kit). If your plane has a heavy wing in its initial flights, after checking the flaps are inline on both sides, and you notice that when flying hands off one aileron is high and one low.

Rib and Spar Wing Kit

Source: 2006 Q3 Beartracks
Following a suggestion from Bob Barrows, AviPro Aircraft now offers to scratch builders a new package of wing parts. The purpose of this package is to eliminate some steps in building your wings that many builders find difficult. Finding an eight foot brake you can use and then bending up your spar webs to match your ribs can be a lengthy trial and error process - hard to get right. If the spar web heights do not closely match the ribs, your wing skins will not look so good. After more than eighty sets of wings, our factory wing team does these bends very precisely.
This package includes the bent spar webs for the main spars, rear spars, false spars, aileron spars, & flap spars. Also included are the only other pieces that require bending on an eight foot brake. These are the aft wing skin stiffeners in the flap area (4 pieces) and the trailing edges for the aileron & flaps (4 pieces). This package includes all the ribs as they come from the factory that professionally hydrforms them. These are 48 nose ribs, 16 main ribs (.025), 8 main ribs (.032), 16 aileron nose ribs, 16 aileron ribs, 26 flap nose ribs, 18 flap ribs, 6 trailing edge ribs, 16 aileron pocket ribs, and the 4 false ribs. All ribs have their lightening holes cut and flanged. The ribs still need to be straightened (fluted), and have their vertical angle stiffeners riveted on. The price for this package is $2350 + shipping/handling/boxes.
The ribs are drop shipped from Oregon, and the spar webs are shipped from Texas. If interested, call or email Mark at N95MF@hotmail.com or 512/626-7886

In an isolated corner of the Mojave Desert you will find a truly “out of this world” destination. Giant Rock Airport was once the gathering place of UFO enthusiasts from around the world, and allegedly, visitors from beyond this world as well.

Controlling Adverse Yaw: Reflexing the Ailerons

Source: 2005 Q3 Beartracks
As more Bearhawks get into the air we should all be prepared for widely varying comments on the way the airplane handles. Some will love it, and some will dislike it. The difference can most likely be found in how the ailerons are rigged.
