voltage regulator?

[sunbeam]

Hi,

I ran my CE today for the first time today, it was fantastic, but.

I kept getting what I called 'black outs', everything went dead for a second or two, just enough to but me into the wall or another car. This happend about 5 times in one race. I moved back down to 10T and the problem got alot better.

I'm told because I'm running 4.8v 'C' cells, brushless 13T and Savox digi 1251 servo the voltage is dropping and turning off the RX. I need a voltage regulator to keep the RX powered up.

I don't know what I'm looking for so can't buy one with confidence. Could somebody point me in the right direction please? On Ebay, all I can find are lipo regs, I'm sure they are not what I want ???????

Thanks.
