Truck stopping/no response

[markwilliamson2001]

Hi

I ran my T4 truck on Sunday outside on a grass track.
At one area of the track (the far left my truck would occasionally cut out (as if it had been switched off), but would come back to life, when coming back towards the rostrum...
It was not a consistent problem, and this point of the track was just coming onto the start straight.

I never had this problem when running inside at a club night...

My setup was as follows:

Trakpower 4900 25C 2S Stick Pack
Losi Excelorin S Speedo and 10.5 motor
Spektrum Std Module & receiver (not pro)
AMB Personal Transponder

Speedo setup:
Lipo 2S - cutoff 6.5v
Initial Acceleration - medium
Drag Brake - off (0%)


The problem did not occur on a fully charged lipo pack during practice (I reused the lipo for rd1 qually, where the problem did occur).

I can possibly put this down to two things -

• The lipo was somehow hitting the cutoff (set on my speedo at 6.5v)
• I wasn't running a power cap on the receiver either, and the receiver was losing voltage for a brief moment..

Can anyone confirm or deny these findings?

Thanks
Mark
