2s and a 4200kv motor does pretty good up to low-mid 20s, much longer runtime and better acceleration but topspeed to be desired running in big spaces, i ran the trinity 4400kv motor on 2s in my now for awhile and it was perfect for the track (1/18th scale tracks that is).

if you try and gear up to much for much over low 20s itll start to run hot, but then agian my now is alot heavy than a lil rc18t
