Brushless Savage - need to know some info!

[Razor_Racer]

Hey guys. I'm planning to do a brushless Savage X, but I need some help.

The motor mount will probably be the hardest, but I hope the folks at RC-Monster can come out with a mount for the Savage...

And I need to know what motor to use. I can use the Quark Monster Pro ESC and a 5s lipo, but I dont know what motor will be the best, and cheapest. I heard that the Neu 1515 1y will be good, but its kind of expensive at 280 bucks, and I dont know if it can handle 5s lipos. Also theres the Feigo 540c XL series of motors, but I dont know if that can handle 5s lipo either, and it seems like its designed for lighter buggies or truggies-not a big Savage X.

Thanks!
