First of all, I'd recommend shimming that motor to remove the up thrust angle--that will lead to all sorts of problems trimming this airplane since it will cause thrust-induced pitch changes. This model needs NO up thrust or down thrust for best results.

That said, you'll find that when set up per the plans (CG, weight, and control deflections) this model is surprisingly sedate during launch. The most important thing to remember is to launch at HALF throttle so that it doesn't torque roll at launch. Throw the model firmly and smoothly at a slight nose up angle (maybe 20 degrees up) and it should fly off smoothly in a gentle climb. If you throw it hard enough it won't drop at all after launch. Bring the throttle up to full soon after launch, get it up to altitude, and then trim it out.

Good luck!

Steve

Thanks for the advice Steve. I'll shim the motor. Flight time - T minus 3hrs, 30 minutes, 10 sec and counting

Hans,

Took her out to the field just now. Found that my battery needed about another 45min on the charger. The wing is at 4mph from SSE. The plane wants to roll left while facing the wind at static, no power applied. Bad sign? I'm gonna launch her anyway!
