Servos .... booster or Rx pack ??

[lordnikon]

I'm having trouble with my core esc what appears to be shutting down and resetting with heavy servo and throttle use on 1s lipo. I've tried a capacitor in the rx which helped a little but not cured it.

So is the solution to add a booster in aswell to bring the voltage up or to run a seperate rx (life) battery pack ? I wanted to run the car on Sunday and am rapidly running out of time to order whatever is needed to sort it out.

Anyone add some options or give any other ideas, not sure what others are doing when running with a 1s on 1/12th
