Buggy on 4s, Truggy on 5s, MT on 5s.

It will work. I had a 8xl I ran in a revo on 4 and 5s for quite a while. It put out good power and was fast. The big adv to the better motors are they have way more TQ and power for the same size, and run far cooler. Having to stop the truck and let the motor cool as it hit 180 is a PITA. Esp if you are running it in a big heavy sav on 5S. A 80mm 1600kv Medusa would be well worth the extra $$ spent.

I'd cut as much accesories (like wheelie bars) out as possible if it meant it would fall into the budget.
