Bill, if the plane has been flown, what elevator trim is it showing? Are the power on and power off trim positions the same?
The four degrees down thrust was added to compensate for too much climb under full power or is that down thrust standard for the build?
If the elevator is close to neutral trim and the power on/off trim are the same... then all is well. Very often however if the elevator is not near neutral... power on/off trims will not be the same and can be made so by slight incidence adjustments. Caveat... remember always that the first step to trim is balance and incidence adjustments should not be made until the balance is correct.
Generally a wing can be shimmed slightly and in the case of your low wing Kouger, the front would be shimmed down by elongating the dowel/s holes and then adding some weather stripping or something to the forward saddle.
115 flights. Trim should be 0, 0, 0. Elevator trim is neutral and power on/off is approximately the same. I don't notice any difference but may have become immune. I have balanced the airplane several times but not as a process of trimming. None of my Kougars fly inverted without lots of down stick which I thought was a normal characteristic.
Thanks for your response. Looking at wing shimming now and it calculates to be slightly over .200" at the front of the wing.
