Well, crap... I have to agree with Jester Again..... The AX65 is a great choice. If I were buying an engine I would probably lean towards the AX75. I live and fly at 5000' altitude and the extra power comes in handy. I always use a mini servo for the throttle to save a little weight. The throttle servo only needs enough torque to open the carb, which isn't much.

Welcome to the wonderful world of glow.
