Hi Folks:
I recently picked up a Lieutenant airplane and I am wondering where should I balance it. Right now, it balances at about the high point of the wing or almost one half of the chord. Since it is similar to a Magician, perhaps it should balance farther forward on the wing. The Magician balances at the spar or about 25% of the wing chord.
The previous owner could not get it to fly with an older O.S. .30 or .35. It was very unstable in flight. Perhaps tail heavy? He had a difficult time doing the pattern as he complained that the maneuvers were quite large.
This airplane has an elliptical shaped wing a la Spitfire. Would this change the C/G? The moments are about the same as the Magician. If I get it balance where the Magician balances, I need about a 14 oz. engine.
This is a great looking airolane and I would like to get it to fly well!
The engines that I have to try include:
Fox .36
Fox .40 Stunt 1972
O.S. .40S
O.S .40 LA and FP
S.T. .49 Sport
S.T. G21/.46
Any suggestions?
Tia,
Frank
