Bill: Great upgrade. I think my Eagle 50 is on the shelf because the blades took off in the living room, it crashed, grabbed both rotors (front and rear) and now, neither motor will turn and I'm afraid if burned out the 4 in 1(or is it called a 6 in 1 on a six channel??). Or both motors burned up. Either way, it's an expensive thing to learn to read the Manuall FIRST, cause turn on the TX first THEN plug in the battery..I did the opposite and besides these parts, almost had to make a trip to the ER, Chuck
