I have the Spartan v2 and struggle with the LPC.... The ESC in the v2 har both water in and out on the front part of the ESC (closest to the motor).
When I run my Spartan in "boring mode" with the nimh's and LPC off (ESC light red) everything is ok..
When I put in my lipo's and turn on the LPC (ESC light green) the engine cuts off very quickly. I can get a full throttle start and go for 5-10 secs but what seems to be the LPC then cuts power to appx 25-50%. If I release the throttle to neutral and hit it again I get the same behavior.
The ESC and motor is cold when this happens and the ESC lights green as everything is normal. The batteries are fully balanced, all cells showing 4.2 V and after the run they are from 4.08-4.12v (ref my charger). I have used the same type of batteries on my e-revo for 18 months without any problems.
I have also restored my controller to factory settings following the manual instructions...
Any idea folks?
