Are you going to try to use this plane as a trainer? If so, I do not recommend it. The Saito .82 will be a great match but tailweight will be needed, even if you put the servos in the tail. I do not have exact numbers yet, will advise when I have balanced mine with Saito .65. The 3151's will be just fine, I use old 148's and 3004's, no problems.
