REFLECTOR: Trim

>> I shimmed the right wing lower bolt with one thin washer approx .025 in.
>> Flew airplane and really could not tell a difference it may have helped a 
>> bit but not what I expected. Still required left rudder and right aileron 
>> to center the ball. Wing to strake mismatch at the leading edge was quite 
>> a bit.
>> I removed the shim and now I'm going to shim the the left rudder out and 
>> see what that does.
