Nick · **BKWanderer XL against Feigao XL -** 01.20.2006, 07:24 PM

I did abit of research today into the BK xl motors and Feigao xl motors.

Alot of people said they are the same and so on but found that the KV rating was different by around 200-300kv a volt.

Taking the 7xl as an example:
Wanderer = 2145kv
Feigao = 2382kv

So the Feigao appears to be the better motor but again wondering how much difference it would make, I did an example on 16 cells: (assuming all the cells were of top 1.2v).

2145 x 19.2 = 41184
2382 x 19.2 = 45734

So it has a large difference, I'm guessing nearly a whole cell power difference? Not sure how KV ratings worked and I hoped those calculations are correct.

Why have RCM stopped Feigao XL motors?

Anyway, I hope my research is correct, was intresting to read about, hope someone can tell me abit more about KV ratings, thanks. :)
