Confused about motor range

[Serum]

Hi!

Welcome to the forum

1 the number of winds is just as with normal electric motors. the lower the number of winds, the higher the rpm's per volt (KV) with this comes a higher current-draw/shorter runtime.
2 540 is the size of a motor, which have got a 36mm diameter. The 540C actually is a 380 sized motor, but because of it's heatsink, it's a 540 sized. the S/L/XL are different lengths, with XL being to tallest.
3 Lehners are hand wind, and use segmented magnets. (makes it less hot on a partial load) What you pay is what you get. A lehner is better than a feigao, no way around it. Better built (screwed endbells) better bearings.. Everything is better with a Lehner. Only the price/preformance ratio of the Wanderers/Feigao's is better. The Neu motors are very sweet and sexy, but they are cheaper than the Lehners
4 in your savage, a Quark 125 with a wanderer 8/9XL on 14 cells would be great. I used an 8XL on 16 cells in mine, and i was pleased with it.
