Medusa is out of business w/ motors now from my understanding.. Typically truggy drivers go for a 1700kv ish motor w/ a 5s lipo config. The 2200kv Monster will do the trick though if it's not needed in the buggy. Just make sure you have GOOD 4s lipo's that can take a ton of draw, junk packs will die quick in Truggy setups.
