I have just bought a trex 550 with an align 3gx gyro, all worked fine and hovered it a bit but wanted to chnage the gyro for a gpro, i have the gpro installed with all the wires in the correct places but nothing is happening, i think this is due to my esc not arming and i dont know why it isnt!?

My setup is Castle Talon 90, futaba T7C tx, futaba R617FS reciever and the gpro gyro

can anyone tell me how to set all this up correctly!?
Thank you!
