what do you think about this ?

My motor is only rated for 70A and is smaller than the 22/35. Mega uses continuous rating and your motor will put out more power. I've seen spikes of 90A with my motor. Keep in mind that electric motor makes power from torque and the Mega being a 6 pole motor has tons of torque. If you see some graphs from data loggers, you will only see the spike and then the AMPs fall as the vehicle starts moving.

ok, and on the mbx5 in 4s,
he don't will become very hot ?

and what is his power (in this configuration) compared at a nitro buggy ?


thanks

My set up makes 1600+ watts with 22.2 volts. You can't just calculate the watts from the conservative rating Mega puts on their motors. The ACn22/35/1E will make more torque then my ACn22/30/2 and all you will need to do is find the right gearing for your vehicle. My truck has the 3.30 buggy diffs, 49T spur/14T pinion and my final ratio is 11.55. My motor never got hot at all and the Mega 35/1E will make more torque.
