I have a Park 400 Outrunner in mine. It powers it very nicely. It has powered both of my Yaks. The first one met my mailbox. I figured it was time for it to go to glory. Now, I have one that I have had for about 6 months now. It flies just as good as the old one.

Servos are Hitec and GWS. If I were you, I would just go all around Hitec HS-55's. They are inexpensive and nice.
