Devo 12

Hi every one i have a problem,i brought a DJI-F550 with a DEVO 12 TX-RX inplace when i first got it it was fine and working ok
ive left it for a while. Then the other day i put the lipo on charge and went to fly it, but for some reason it wasnt working I because of the NAZA-V2 didnt have signal. So I did the NAZA GPS dance and was ready to go then this!!!!!!! I can use the bomb bay and the gopro gimbal but for some reaseon it just wont engage the rotors so it wont take off? any body have any idea what the start up is or do the sticks have to be an any possion???? Looking forward to any help or ideas.
Regards PAUL

Hi, Paul,

did you turn the throttle trim next to the stick to the lowest position?
