RE: Super Duellist 2/60 Build
Pete:
My way for lateral balance is to complete the wing construction except cfor covering and the tips. On a plane with a long wing just the difference in hollowing the two tips is sometimes sufficient, even with both engine cylinders pointed the same way.
With the engines and servos, tanks, etc mounted, hollow the right tip (assuming the cylinxders are on the right), set the hollowed r/h tip on the right end of the wing, and set the shaped but not hollowed tip on the left wing tip, and go from there.
