model/engine question
I am with Texas 3D on this one, I had a Rossi .53 on my Top Cap and switched to the Saito .72 with a 14x4W APC and it will hover at 1/4 throttle and has very even power. The Saito didn't even add any more weight. IMHO this would be the perfect power for the model you are looking at. I love Rossi's on a fast mover but on a funfly I am sold on the .72 Saito.
