best motor for e-revo

[Dafni]

Whatever you get, I'd strongly suggest this site here.
The shop is quick and as safe as it can get. Plus, you can get everything you need at one stop, if it's not listed on the site just email Mike, he'll take care of you.

For under 300 bucks, I'd get a Mamba Max ESC and a Wanderer. Assuming 4S I'd take a 7XL and a 8XL.
As for the best there is, you'll have to spend more than 300 I'm afraid, as the high end motors alone go almost for that. But you won't be disapointed with the Wanderers either, as the main difference between your 90 bucks Wanderer and the $300 Lehners is efficiency (less heat, bit more runtime)

Hope this helps

Edit: forgot about the UBEC... you'll need one for the MM on anything above 3S Lipo.
