I'm running an Supertigre 45 with mouse can pipe on mine. Using an topflite 11x4 wood prop. The st 45 turns this around 14600 rpm's. It weighs around 4.25 lbs. I have Hitec 605 on ail, jr 8321 on elev, jr 531 on rudder, and an mini on throttle. Using an 4 cell battery.

It flys great, this is the second one I have had. Have an lot of fun with it. With flap to elev mixing it will do an really small loop. Take off in about 2 ft.
