Hello!!
I drove it after upgrading from Big Rock 3S to 4S.
4S have different powers.
Hobby Wing series
Transmission MAX10 SCT 120A
Motor 3660SL G2 Brushless motor 3200KV
The price-performance ratio is good.
There is a slight heat cut phenomenon, but even if the pinion is lowered a little
Speed doesn't seem to be a problem.
Currently it is a pinion gear 15T.
It's a fun little car. ^^
