soooo after a few expensive lessons in gearing, i am here now:

losi xxx-sct - went from ball diff to gear diff
tekin rs blinky
tekin redline 17.5 w/ 12.5mm ht rotor
no can timing
76/28
thunder power g6 pro race 5300 65c 2s
sdrc raceway: med to high bite indoor off road clay track, long 90' - 100' straight
we just ran jbrl rd 6.

after 6 min run, motor is luke warm. esc is cold. i am thinking i can go up a pinion or two....or maybe add some timing. any suggestions anyone? should i gear up or add timing? she's a little slow on the straight, but the motor runs a lot nicer than the sonic.
