To go inside I'd recommend an 18-19t and keeping a CLOSE eye on temps. So far I've never temp'd above 180 and I have a very twitchy throttle style (ala nitro guys who stab the throttle). I am not by any stretch of the imagination FAST yet either though. So take it for what it's worth (nothing more than you paid to read it)!
Agreed all the way around on 4s.
I don't have a twitchy throttle finger and generally don't hammer on the brakes, etc and on outdoor tracks on 85+ degree days I was running around 150 motor, 120 ESC, 95ish on the batteries; and thats with no air vents cut in the body, and no crazy esc settings.
