It is impossible to tell.
It depends on what size track, what size tires, if you're drive trane is free (as in not causing unncessasary strain on your motor) and how long you have driven the car since you last turned the motor, and if you ran an entire pack till it was dead.

Yeah check your drivetrain, it should run smoothly. For gearing, normally what I do is run for a few minutes and see if the motor is hot. If its just too hot to touch, use a smaller pinion.

with the T2 84 pitch i always start of with 22 pinion, check the temp after 2min. also for gearing find out where it tops out on the straight. then adjust from there.

there are a lot of factors to consider regarding your fried motor. But first, you need to compute for the Final Drive of your car when using certain motors.

Spur/pinion(internal ratio)=Final drive

It also depends on how the racetrack is(lay-out, size)... i gear my 27T motor from 7.10-6.90 on small tracks, and on long flowing tracks i go down to 6.75...

hope this helps.

There are two types of Tbrood 27T motors the epic base and the monster base. Epic base is an RPM motor and the monster base is a torque motor. (correct me if im wrong).

and one thing more avoid over running your motor... 5mins run is enough, if u still want to run more let your motor cool first before you run again.

ayt!!!

thanks curious mind my final drive ratio was 5.95 and I ran it for more than 5 min just doing quick pulls of the trigger in my garage to test the car out. I have a FT tc4 (battery was lipo) and I did the same thing and my gear ratio was 6.0 and never once did the motor start smoking.

5.95 is way to high for CO27. Go somewhere in 6.5+ range.
