I was playing with mt tamiya Pershing today.
But suddenly whenever I tried to do full throttle, all function stopped
And started again. And stop again with bit of throttle and start again.

Is that a dmd controller trouble or what?

Anybody has same problem?

Did you check that the battery is not the cause? try that first with a different battery. If not, then try reprogramming the dmd unit.</p>

It's the battery browning out. Try cycling the battery or replace.

Thank guys...

Sometime if you have Ni-MH battery w. 5,000mAh, you don't know when you charged your battery.
I will check at home. hopefully easy fix.

Batteries are becoming increasingly more affordable. I suggest getting a couple of new ones. that way you not only have enough on not to ruin a good day of running but you have a quick easy way of doing simple trouble shooting at the field.
