RC4WD excavator turret problem

I just did another test, this time running the electrics for 6 minutes (just swinging the turret round in circles) and all good. Then I turned the hydraulic motor on for 10 mins and did nothing. I then tested the turret again. All good. I started using the hydraulics and again the problem presents.

There's a black box where the servos are hiding in.. should I try and open it up to investigate? I'm just a little worried cause all the hydraulic lines are connected into that part..

I just did another test where I worked the hydraulic servos whilst swinging the turret and it does not stop..

Does that rule out a bad setup for the ESC??
