I'm gearing up 1T on the pinion, lowering LVC to 2.9V per cell and adjusting the ESC punch, etc. to obtain more runtime at present.

I think that with my 8T, MMM, 2200kv, Hyperion 6500mah 4S and some careful trigger finger then I will be OK for 20 minutes.....toying with the idea of trying a 1800kv Tekin or Losi motor though to see what that does.

If not the i might look at some mods that mean a battery change can be done fast in the pits during a final....
