RE: Great Planes Sukhoi SU-31
I have mine set up with a DA50,I put the servos in the tail.I put the 4.8 volt sub c (for radio)on the engine box and the ignition battery 1500 4.8 v on the plate made for battery in front.The ignition went on the engine box...No spinner or wheel pants and got a perfect balance...The DA 50 of course has tons of power and is a bit overkill for this plane but it does fly great...
