Update:
OK here's my setup: rc8t rx8 1700kv combo geared 17/46 5s 5200mah RCM lipo
rx8 settings: DB=off, RS=off, BS=50, NW=50,TP=1, VC=5, PC=off
TA=min, CL=off
Here's the track I run it on (haven't raced yet just happy that I can run down a whole lipo without crashing too much :))

Its geared for about 45-46mph
With the only WOT section in the beginning quad my run-time was 28min

and the temps after the run (it's crazy hot in sacramento right now) were: rx8=4 LEDS, T8=140, Lipo=105

really happy with this setup...it has the punch that i'm used too with the CC2200kv and it runs a lot cooler and more consistent....
