KEVINELP, Ok, Kevin ; Thanks for the info about the throws. The Goldberg site says the stab should be 1 1/4 degree positive when both wings are at 0 degrees. I usually set the throws a little higher than the manufacturer says and keep the stick movements soft. I flew one of these bipes for a fellow club member that was put together by a man who knows about as much about trammeling a model as i do about computers,and i can't recall how we fixed it but the stick had to be offset nearly into the lower right corner of the TX just to fly level. I called the fellow modeler (who has since moved to N. Carolina) and all he could remember was that i told him to shim the trailing edge of the lower wing. i think it also had a lateral balance problem. kc2jk310s Hank
