I put a Hyperion 3025-10 in my Magister, ESC were a Jeti Spin 44 with onboard switched BEC which delivered all the amps needed for all the servoes and powered it with a 4S3700 FlightPower LiPo. Of course two aileron servoes, and tow-release setup.
It was used as my relaxing plane, trainer for new pilots and for towing. It worked well for all the purposes, and towing 2-meter gliders were no problem. The worst problem in fact is the nosewheel... On grass it gives much resistance on takeoff, taildragger would have been much better for towing! I hate nosewheels [:'(]
Don`t remember all the numbers, but think I had appr 550-600 Watt to the motor. Flighttime were generous, but the pupils said it was a bit too fast for training... I agree on that. The plane died when one of my pupils rolled it inverted and added elevator... were 1,3 meters too low for recovery [&o]
