I agree that 4s is fine in a buggy. With 6s you run into problems fitting the larger lipos under the body, and the addl weight really throws off the balance. I run a 1600kv medusa 60mm in my hyper8, and plan to use fp 3200 5s lipos, as my 2170 6s setup just does not have enough runtime.

As far as equipment, a decent budget setup would be the hobbywing 80amp esc with a 2200kv 60mm medusa on some sort of 4s lipo, around 5000mah 20c+.

Better would be the cc mmm 2650 combo on 4s.

The budget setup could easily be done under 300 bucks for motor esc and lipo. You will spend 50-75 bucks more for the MMM setup.
