MERV Gearing

[Hockeyrooster]

I am running a 2s battery with the VXL motor and the kid at the LHS gave me a 31t pinion gear to run with the 50t spur gear. I added it to the car and it is a lot faster. I run the car mostly on the street and do some jumping onto our grass. I don’t drive in the grass that much. Up the street, down the street, over the jump, through the grass, repeat. I check the motor for heat and while it gets hot, I can touch it. I have a heat sink.

The rear diff started to click after using this set up about 15 times so I opened it up and expected the diff to be trashed. It isn’t. I bought a new diff housing (had a couple of worn out holes on the old one) and added one shim while I was in there. There was no shim previously.

Question for you fellow RCers is, do you have any concerns with this gearing? I’d love to hear your thoughts and opinions

I don't own a mini e revo but keep your electronics under 160°F and you won't kill them up. If they go near that lower the tooth count on your pinion

That makes complete sense to me. How do RCers measure engine temps? I don’t see bung for a temp sensor (this is a very weak attempt at humour). Seriously though, one of those surface reading gun type things?

Temp gun. Got mine for 24 bucks at the time at harbor freight. Use it every race night or bash session.
Good useful tool for the tool box
