Little back ground; radio/receiver is around 1 1/2 years old. Up until 2 months ago was used with a TekinRS in blinky. For the last 2 months I have been running an Orion R10 with a Thunder power 5.5 motor. The only thing plugged into the receiver is the esc, the KO servo and the my laps transponder.

Now what happened. At this weekends race i went wide open throttle, let off, tapped the brakes lightly and the car lost signal and coasted to a stop. This all happened on the first warm up lap The receiver had no light on. I tried to rebind it, no luck.

The light still won't come on the receiver even after taking the cover off of it and cleaning out all the carpet and debris that was in it.

I borrowed another racers car with a ko receiver and my controller bound up to it, no problem.

My question is what caused the receiver to go out?

Do I need to run a cap on the receiver?

Would that have saved this from happening?

Or just chalk this up to it being old and debris in it?

Thanks for the help

If I understand correctly, you tried another car with your transmitter, not a different receiver in your car?

Unplug the transponder and servo to eliminate any possible short (unlikely, but can happen).

Is your esc providing power to the receiver? Check the wires in the esc servo plug, make sure they or the plug didn’t pull part way out. Try a receiver battery (pull the esc plug first to be safe), and/or use a voltmeter on the esc servo plug to see if it’s providing anything (should be 5~6 volts dc across red & black).

Basically check all the simple stuff first before giving up on the rx.

If it doesn’t power up then it may not be promising. Probably either KO service or a new receiver it seems to me.

Thanks I will try that first.

I did call KO but no reply, even emailed them also. I am hoping it is something simple that would be nice.

Well your advice was good; I was ahead of myself on assuming it was the receiver. I tested the voltage coming out of the esc, zero volts

Good and bad I guess. Sending the speedo off and will new back in business.
