I need help to get a little more speed on my RC10T4.3

[RC10th]

I think I ran 26/87 with a 3450kv 10.5T

Quick update guys:   I re-calibrated the ESC and speed went up from 20 to 25 mph  which is great news !  so thank you for the advice !

A different question now:  If I want to bump top speed from 25 mph to 30 mph,  re-gearing sounds like an option. Current  pinion is 18T but the motor manual says  19T is a safe average. Should I try a 19T pinion to test speed and temperature or should I jump to one even higher like 20 or 23 ?  

Note: the motor is still only warm by running at 25 mph for quite a while, looks like there is room for temperature there and re-gearing.

​​​​​​​Thanks guys !

try a 22 or 23 tooth pinion. It won't hurt doing testing with a larger pinion. Worst case is you run it around and if it lugs and gets hot, you know you are overgeared. Otherwise, it will probably be fine.

Great to hear you're back on track with the ESC recalibration. Keep in mind that, all else being equal, the higher you gear up for top speed, the slower your acceleration will be. You can compensate for this somewhat by adjusting your ESC "Punch" setting.
