Hi
I have analign trex 450 pro. After programing the 3GX according to your videos, all servos are working perfect but the motor doesn't. Some times the motor works for like a nanosecond. I tried to chang the motor, another time to change the ESC but still no responce. Please if anyone has this issue before or know how to repair it. Please advise.
Thanks

Make certain you don't have a throttle hold enabled... if so disable whatever switch you had programmed for that....

Then calibrate your ESC according to the instructions given in it's manual. Typically, but not always since this can differ depending on brand, you will start with your throttle stick all the way up and then plug in your battery and bring your throttle stick all of the way down. That should arm the ESC and enable your throttle to work. Sometimes what your throttle's trim is set at will also affect if it arms or not and you'd need to fiddle with it's trim so it senses the no throttle spot.

The problem on the 3GX system has to be the same... how to resolve it when the throttle goes through the 3GX I can't help with ( I don't use gyro's on my airplanes)... hopefully someone familiar with them will come along and post up a suggestion or info on the steps needed.
