so I think I'm getting 'brownout's' with my setup. I would be running just fine and then all of a sudden, truck would shut off and/or would have steering and no throttle and/or throttle/esc would come on/off. the rx8 was giving an indication of low/no transmitter signal (all led's blinking). very weird.

It's weird cause it's an intermittent problem. Not sure if it is a combination of the pro4,rx8 and savox servo drawing too much amps at the same time or if it possibly is another problem like my transmitter not having enough volts/charge?? Randy Pike said maybe my transmitter is frequency hopping?? He also said to throw a cap on, so fingers crossed.

I have a spectrum cap that I'm going to throw in the receiver to see if it fixes the problem.
