Electric Motor Issue on Twin Engine Blimp

by Terry
(Columbus, Ohio)

We are flying a twin engine electric blimp. Each engine is on its own channel mixed in the transmitter. Works perfect 99% of the time.

Occasionally one of the motors will start to oscillate and overheat for no reason. It has now happened to both motors. Really draws the main battery down.

Any thoughts what might be causing this?

RX Short?
by: rcdude07

Is it possible the range movement on the two sticks/motors are slightly off causing one to go further than the other?

What brand motors? Cheap Chinese ones will not be as reliable as name brand ones like Electrifly and Rimfire.

How long into the flight does this problem show up? Towards the end of the flight when the motors have been running for quite sometime?

Where is the RX located? Just want to rule out RX interference (carbon fiber bodies are not good for signals penetrating).

Event 2 motors of the same brand will not be 100% in sync due to slight differences in the magnets and coils.
