Didn't look it over, but ask AJ he'll tell ya what's hot lately. I think he's running 25 FX's but that's the last time I looked. It's a bulletproof engine and you really can't go wrong with it. There are other, 'high output' engines that are finicky for even engine men and they really aren't worth the effort that the 25FX will do you. Certainly HS-85s are equivalent will be fine for the plane, but with that much wing I don't see how full size standard servos would be too much problem. I used to run micros on my scale ships, but there you are limited by wingarea and every bit of weight counts.

Contact AJ AND check out the Team Seaholm forum that you'll find on the home page. He's good people and has a good product. But that probably goes for all the guys selling planes right now. Too many good competitors to be a stinker.
