RE: wanna see the inside of a lipo?
the prop torque thing came up if i applied power too quickly--the plane would spin quickly to the left. thinking back i guess i could have given quick bursts of throttle to oppose the right turning tendency. it had a little downthrust, but none to either side. i set up the rudder as best i could; the control rod was perpendicular to the servo arm at neutral, and deflections measured 1/2" both ways.
both wing halves rested flat on a couter-top, even after heat shrinking the covering. i don't know of any other methods to look for a warped wing.
i built the tail feathers as close to perpendicular as i could, so i'm still clueless about the right turning being better than the other way.
what i thought on the first flight was that the cheap gws naro was glitching. i could hold the stick all the way to the left with no result, then return it to neutral and quickly snap it back to the left and the plane would respond. then it did the same thing with a hitec servo.
