Fusion Exceed 13.5 cutting out

[almunro]

I have a 13.5 combo in my mardave running off 4.8v 4cell until my lipo arrives. Problem i get is the throttle cuts out after about 1 min of racing, then wont work for a min, then starts again and works fine for the rest of the race.

When its not working it has a constant red light on the esc. Is this a voltage problem from not running a booster? Various people on here have claimed that the combo works for them on 1s lipo without booster, so i wouldve thought it would work a on a 4.8v 4cell without also.

Any thoughts?

Thanks
Alex
