The thing is though, the bigger motor at higher hv is only going to have more torque if you have some amazing 2s packs. Otherwise, like I said, it takes more power just to get a bigger motor running. It might end up being more powerful but more power = more heat even if efficiency is the same. I'm not exactly sure if bigger motors are generally more efficient than smaller motors. Then again, I'm sure there is nothing wrong with going with a 1509, but if it's between a feigao L/XL in power, that would even be more than enough for a 1/8 buggy.

True

But if the L can runs cool in a crt.5 and thats a 10L, and thats not much Kv, I think a more efficent motor, and a little bit higher KV, should work

But I dont know
