I think you misunderstood the lipo situation for 12th...
you will have less volts than a 4 cell "round" battery pack.
The output vuoltage would be 3.7 nominal or 4.2 peak.
But I love what lipos are doing for making maintenance way way easier,
let alone the onslaught of brushless motors.
I Hope there will be a class of 1c 5700mAh and whatever motor makes the 10R5 and other cars like it fun. Something like 7.5L Velosity.
I dont want ppl to come and ruin this new GT class or 12th.
which is where the foam tires belong ... not on T/C 4wd cars!
