RE: Replacing a .40 engine with a .60 in a Trainer
I have a supertigre .61 ringed version in my arrow trainer and i have not too much power at all.Even though i just learning to fly ,fellow at the club advised it.I had to use a half of stick of lead on the teal to balance it out but that want's big of a deal.And about limiting throttle travel-if you get computer radio you get a 'travel rate" on all of your servos.
Good luck
