Well the mm definately works on 4s, not sure about 5s. Personally I like 5s setups, and I run a 2000kv motor in a revo with a tekno kit on 5s 5000mah 20c lipos. I get about 35mins of runtime and everything stays cool. I use a quark 80 airmaster, with the stock mech brakes. If you are staying with the mm I would go with a 8xl and 4s lipo, possibly a pair of trakpower lipos wired in series, 4s 4900mah. Real good lipos, I run them with both a 7xl and 8xl in revo based trucks.
