This in on my new Dynam C188. I thought it was the RX so started this thread.

I don't get why the servo tester will work but two different RX won't...

Sounds like the speed control might not be arming the motor on startup. Make sure throttle is 0 at low stick, and if you haven`t already, try resetting the throttle end points in the speed control.


Thanks Geena. I am leaning to the ESC and or its programing. I remember programing the ESC on my heli. I found an manual online to program it...

Just spoiled I guess from the usual plug up and go. I've never pulled a new plane out of the box or done a build that has done this.

After the number of users here that have reported their ESC didn't arm without first calibrating their throttle to the ESC... I'd consider that a first step every time now no matter what brand you use.
