This is a Electrifly Firebat maybe 6yoa ARF. It has its 2nd motor in it. I rewound the Asian KD KA450H 3200kv brushless Heli Motor for this flight. I used 22AWG wire and 9 turns. The battery is a Rhino 2200Mah 11.1v 20 C Lipo. Prop 5.5 X 4.5 APC-e Pusher. The plane weighs 26.0 ounces ready to fly. Speed is unknown.
