LRP S8 conversion, whats setting?

If you are thinking of just getting the motor, you may want to consider a Medusa 36-60 with 3100kv. It is being sold here: http://www.rc-monster.com/proddetail...usa3660&cat=20

It is a bit cheaper than the 2650. The 3100 will spin at 35k and 45k with 3s and 4s, respectively - which are good RPM's

I have the 2200kv on 4s, and it works great: has lots of torque and runs cool.
