RE: U-Can-Do 3d 46?
I installed an OS 70 Surpass II with a 13X4W prop. The plane will hover but with the existing engine it lacks authority. The vertical climb could be much better. So, I've decided to get a Saito 100 based upon the posts I've read here at RCU.
For those of you who fly the plane with the Saito 100 what prop are you using?
