Took the profile up to '7' and the motor came off at 70degC! while the ESC was 60degC
This was all with the same gearing as usual.
Several other guys were one pinion down.
This was on medium grip mid-size asphalt;
Several people commented it was a rocket down the straight and into the sweeper.
It does require the room to wind itself up to speed, so I'm not sure how effective it would be on smaller tracks or in off road where there aren't any large straights and grip is not as high as on-road.

You deffo need to drop some teeth down (I had to drop about 2 in 10.5T), then the show starts. I would start with 4 teeth down and profile 7!? You'll see temps, if it's not too high then you can go some teeth back up. It's truth that you won't loose anything, when you drop pinion - it'll rev up on straight without problems and you will be at least as fast as with your standart gearing and lower profiles or TC comp esc.
