Don't worry about it , I flew one with a G90 on it and I have another with a Saito 100. Very stable plane. Once trimmed out it holds and flys like its on rails. I do hope you beefed up the retract mounting blocks, When my P-51 with the G90 went in a couple years ago from battery failure, that thing was scattered over 1oo feet but those retracts were still in their place.!

Another thing, if you dead stick and you know your not going to make it back to the runway. LEAVE THE GEAR UP AND LAND ON THE BELLY- If you bring the gear down there willnot be much left of your wing
