I just finished this plane and I'm thinking about putting SAITO 72 on it. Would this engine give me unlimited vertical performance on a 6lb 3D plane? What prop should I use?

Thanks,

R.P.

If you are going to put the Saito .72 on it try an APC 14 X 5n prop with 25% nitro. It will easily 3D this plane and keep the speed down even at full throtle.
