I'm a little concerned about my speed control now. Up until this thread, I was running the "wrong" way. About a month ago, I had a problem where the radio system would just "die" for a few seconds. I assumed it was a problem with the receiver and swapped it. After reading this thread I converted to the Lipo wired in the switch line. Worked great for a round and then the problem came back after doing some tweaks in hotwire. I did a discharge test on the 300mah lipo to make sure it wasn't going south. Checked fine. All the connections seemed good. Tried a receiver rebind and it had problems rebinding. Which is something I have seen when they don't have enough voltage.

I turned the lipo cutoff "off" and the problem seems to have gone away.
I'm not real confident it is really fixed.

Any chance the internal regulator could be acting up causing the receiver to power down?

Would a voltmeter on the power rail of the receiver show any problems with the regulator circuit?
