I think we are going to try longer mains at our local track (
www.fastlanehobby.com) this winter.
6-7 minutes for touring and 9-10minutes for 1/12th.
right now we have 1.5 to 2.5 minutes of run time left after our current 5 minutes.
you say "gear up"---we have, to the point of cooking a few of our c2 19t motors.
we are running 1yr & 2yr old 3300 packs that we recently started to dead short. that added 500-750 mah to our packs and increased our voltage immensely!!!!!!!!!!
NO reason to buy new packs yet!!!
