OS .46 or Irvine .53 2 stroke. People are also having excellent results with the TT .46. Saito .72 4 stroke. For servos, Hitec 225MGs work well on all surfaces, with a small mini on throttle. No need to go any beefier than these. They've been flying mine prefectly well for quite a while.

Hurry up and get one. You won't be sorry!
