Default 1/12th Motor amp draw

Does anybody know the average motor amp draw for a 1/12th scale(8 min races). Both for stock(green/green springs) and a 10-12t mod.

Thanks.

Someone tested it with a data logger in 1/12th stock last year and we saw spikes up to 45 amps when nailing the brakes in a corner when going too hot, but I think it was between 10 and 20 amps average.

It has been a while though. 12th scales have almost no drag so it would have to depend on the power that the motor it pulling and then the rollout and the average rpm of the motor over the run. Was it spooling up, or is it overgeared. Is the motor hitting it's peak rpm. Everyone's car will be different. Good luck.
