RE: ESC location
Two Reactions are shown, One powered by a Wren 44 and the other by EDF.
The EDF is the blue, yellow, green plane. The black area on the top of the body above the wing is where the ESC sits flush with the body. Very cool running. The ESC is a Turnigy 100 that pulls 62 amps from 12s 5000 driving a Turnigy 4.5 fan. Plane weighs 14 lb with retracts, flaps, and brake.
