My Pizazz is set up similar to finnz. OS61FX, 13-6, rudder under the stab. I still had to add 3oz to the tail to balance at 4 1/2". More than enough power to pull out of a hover. Almost too much. I have a hard time keeping it from climbing. The Pizazz has been a good tool to improve my flying. I'm still too chicken to hover below 20', but the overall improvement in my skills has been dramatic. I see it more as a mini-Imac trainer rather than a true fun fly. The only flaw I see is poor snap performance. It doesn't stall cleanly. I must have done something right..no flutter even at full speed. Very fun plane to fly, even in high wind.
