Knife edge loop?
The servo is a TS-65, it is 77oz/in at 4.8v and Tower doesn't list the 6.0v rating but I remember it was right around 100oz/in which I think SHOULD be enough. The plane is right at 11lbs, has a Saito 1.80, CG is slightly ahead of aft recomendation (will change as I get used to plane) and rudder throw is right at 3". I am running a Master Airscrew "classic" 16x10 prop which I think may be a power robbing dog but I can't confirm as of yet. I'll get some different props to play with this weekend hopefully.
The reason I didn't immediately suspect the plane is that on my old plane, a .46 powered Kyosho Cap w/standard servos, my instructor did one right off the bat and I was never able to duplicate. Unfortunately I no longer live near that field and can't ask for more assistance from him but I'm guessing there's a 'trick'. Maybe I'll try moving CG aft a pinch at a time.
