Hobbywing Axe Overheating

[MarcoMayhem]

Hi everyone! This is my first post so i hope it chose the right place to post this. So i got the Hobbywing Axe 3300kv in my Trx4 sport but it happens to overheat a lot. Since we are in quarantine I'm using it in my back yard I am never on full throttle due to the size of the yard. I have 45t spur with 12t pinion that came with the system. Its been on letter D for the mesh settings and i was told to try letter E as well but it still runs hot on both settings. Yes all wires are soldrred correctly letters a to a b to b and c to c. No I don't have a heat gun i use my finger i can't keep my finger on the motor for more than 3 seconds.

Did you bind the motor to the esc? I don't know what it's called but you hook up the motor to the esc with it out of the vehicle, then power it on with no reciever. The motor spins and does some calabrating. Then you install it.

With my older motor and esc, it got way hot way fast. Like in seconds I think. Had to do that after the 550 firmware update.

My motor and esc are from the first batch that came out. So newer versions may act differently and just run hot until it's done.


Also while you have the motor out to do that, check that the drive train spins easily with no binding. You could have a bad bearing some where.

What Vodo said....something is setup incorrectly it shouldn't be hot from what you are describing, after you calibrate the motor, check your programing setup parameters.

also pinion mesh could be too tight.

Try a 10T pinion or less, I run my TRX6 on 10t pinion stock spur with the AXE 2700kv doesn't overheat at all. Try a very low gear pinion like 10t or 8t

If you've swapped wheels make sure they arent rubbing and causing drag.

Who makes a 32p 5mm pinion for the axe?

5mm is the shaft size. That's a 1/8in pinion.
