I've found that there is usually a dab of solder that won't let the make plug compress enough to fit into the female. I just give it a light squeeze working all around the male plug and it will then slip in. If it becomes too loose then a fine screw driver and pull the ears out slightly.
Thank you that worked! lol Now cant get the motor to run. I am using an ar620 Antenna and form what I understand is that the bat for extra battery and channel 1 is for throttle. But, does it activate the failsafe and turn off the throttle and if does how do I turn it on? Im using a DX6e and the servos for tale work just fine. Do have to do anything with the preset failsafe on the AR620?
