I put about 2800 mAh back into it after a 10 min main with a few min warm up. The one time I ran to LVC, I think I was on the track around 18 min or so, but you have to take into consideration that's 18 min of practice, not racing. Practice will yield longer run times because you sometimes have to check up for wrecks or just avoid other cars because there are too many out there.

I run a 2100kv motor and I'm pretty easy on the trigger. This was on 2 medium - large tracks (~200 foot straights)
