I also have a Ultra Stick and went with the Saito 100. I haven't regreted it at all. It even balanced out nice. I've heard from others that the wood quality of the kit veries greatly from one kit to the next so maybe I just got lucky with the balance. Also go with the flap option. Drop the flaps, put power to it and take off in the length of a small car. Just break the engine in as published and adjust the valves (easy) and fly it. I'll have to try the prop size people have been talking about though. I've been running a 14 X 10.
