Ansmann 60A esc, what max motor?

[Appie53]

Dear Guy's, there's a 60A esc in my RTR rat, with a 12T motor.
Now my question, what would be the max motor for a 60A esc?
Iám using 5000A 35c lipo's, so I could use some more speed, or must I look for other pinons then 21T.
Thanks for your advice, sorry it's needed.

I had a 60a hobbywing esc and it worked fine with a 8.5 turn

I would definatly gear it up. I use a 21 pinion on a 6.5 so I would say get some bigger pinions maybe start at a 24 and work your way up from there.

When gearing up be careful with the gearbox as it can break with the extra power, but there is a guy on eBay selling Kevlar gears

Ermm why? The idler gears going have nothing to do with gearing usually, it is more down to the slipper clutch overheating. Best practice would be to buy the newer acetal or nylon idler gears to be safe.

When you are gearing up go up a tooth at a time and check the motor is not getting too hot after a normal length run.

I just heard alot about people breaking the idler gears with a brushless motor
