Got my first flight today after the destruction of my Shoestring Stunter a few weeks ago. The rebuilt hand me down Cosmic Wind flew! It flew rather well, in fact! Stable but very responsive. CG seemed perfect.
I had recently learned one of my issues was far too much elevator deflection. Between talking to Mark and watching Shug's interesting video with cameras on the plane, I understand better how little is really needed. I had replaced the elevator with a slightly larger one, and gave it 20 deg max deflection. Was quite sufficient. Looped quite well.
Only had time for one flight, but it was great. The OS 20FP was quite up to the task of powering the 400sq in/ 34 oz plane. (Just slightly more than the SS's 385/32).
Dane, can't thank you enough for the engine work. It ran perfectly.
Between Mark, Shug and Dane I'm back in the air!
