Or both is as good? |
Personally a 3000-3500 kv motor on 3s is my choice. That puts you between 33k and 40k rpm max. That would be for a smaller motor like a 50mm medusa, neu 1506, or a feigao s can, or the vxl motor. The smaller pinion will decrease the load and the higher rpm will make up for it. Plus it will start from standstill easier, due to the lower gearing.
A larger motor, like a feigao l can will have more torque, and will pull higher gearing. Seems like a 9l on 3s is a great setup for a pede/rustler. Plenty of power, and not really sensitive to gearing. Plus they run cooler. And it is cheap...
If you go with a high quality motor like a neu, or even the medusa, a smaller motor will be fine. I just generally try to keep the rpm somewhere around 35k...
