Yes, you can use 3 T Pro servos on this. Teh plans have it for 2 aileron and 1 elevator. And let me tell you, this elevator is HUGE lol. I think you could cut it in half and make it better.
And I would run a 2500kv motor on 3S with a 6x4 prop. I think Lee's motor was a 2350 on 4s, but don't quote me. I believe it's posted in the first page of this thread. But, 2500kv with a 2200mah battery will work great. Just remember, this is a propjet and it is VERY twitchy for those that are just getting into it.
My opinion, build the RCH trainer and learn that, then this one. Might save you a little foam in the end. But if your like me, you will skip the trainer (everyone should build the trainer...) and go straight for the jet lol.
If you build this, go to walmart and get some spray insulation foam and fill the nose up with it. It will save the nose when you crash. Or try to help save the nsoe lol. Check out my FF-22 maiden flight. I cracked the nose, but it didn't break off.
