Maxx Bling

[Serum]

The 7Xl would be about the same rpm range on 16 cells. A 9920 controller could take this for sure. (a user on this forum uses the 7XL on 18 cells in his maxx)

But is it worth the change? If you want more power, you need to use more cells!

Mike has got the feigao 7XL motor, thought they are about 90 dollars. Those wanderers are blue in colour, the feigao's are purple, but easy to polish blinging silver.

You can just try this motor on 16 cells in your maxx, you'll be able to loose it on ebay if you don't like it enough and you can buy a more powerfull one, with a beefy controller as well.
