My FX707S RC conversion had a rather interesting maiden, mainly as a result of a silly mistake I made when setting it up! It survived though, despite cartwheeling on one 'landing'. (Foamies can take it!) It'll hopefully be easier to fly next time. I'd built my RC conversion to the same CG as where it was when it was a chuck glider, but strongly suspect (mid-chord?) was way too far back for power. But like I say, that was where it was when it came out of the box and I assembled it!
