I think 18/77 wouls be too low geared and it would run very slow and might be over-reving. How did you get a 77 tooth spur gear? and what tires are you running?

Can you give us all your setup for the motor and esc?(include the tires as well)

I have run mine with 40 series wabash and bowties, with 17/66 gearing and 12 cells with no trouble for over 15 minutes, with 4.4k's from Maxamps and the only problem i have had was going to a reciever pack because the internal BEC couldn't keep up (expected), but i haven't had trouble with heat or cogging like some others have described.
