i own a ECX torment and wondering what kv I'm looking for. i see the castle sidewinder act system is recommended and that 3800v. i also see lots of people running as high as 5700v to. I'm looking for something with solid performance on 2s and when i get the 3s bug I could hit 50-60mph for bragging rights. Will be a basher.

5700 KV is a nasty fast motor. I have one and ran it in two wheel drive mod buggy in the past. Fast and had enough torque to pull wheelie anywhere on the track at any time.
