When I was test flying my Bearhawk I noticed that in level flight the right aileron was reflexed slightly more than the left. It flew very stable, wings level, even hands off. There are two possible causes for this. The result of a heavy wing, possibly the 2 lbs of magnetometer and landing light in the left wing which showed up as a 12 lb higher weight on the left wheel at the W&B (a head scratcher). If the aileron hinges are not perfectly aligned when match-drilled to the af

Related links: Heavy Wing There's plenty written about how to build the Bearhawk, but very little about how to rig it well. Rigging it correctly will give a well balanced aircraft that is a delight to fly. We made many adjustments during the initial test flying, with the assistance of the forum and fellow Bearhawk builder Kevin Deutscher. It is assumed that cables will be correctly tensioned to manufacturers recommended tension where applicable or those provided by the AC43
