Team Associated SC10 Gearing

[SpeedyBooty]

Hey guys I recently got this sc10 roller and wanted to fit my own set of electronics and I wanted to make sure the pinion would work on it , I’m running a brushless 3000kv 380L 28x50, not sure what the last 2 things mean but I just want to know if I need to gear up or down, I currently have a 27t on the motor.
Thanks

The hardest part is trying to guess how much power your 380 motor translates to a traditional 540 spec motor, where the following chart is based on 540 motors which offer more torque.

It's possible that the 27T pinion may work perfectly fine, but I would still check temps and gear accordingly:

• What gearing for upgraded electronics?

Do you know the stock spur for this one

Do you know the stock spur for this one

I no longer own the truck but I'm going to go out on a limb with both lines of stock gearing are 19T/87T

Thanks again bill

So I just ran the truck outside to test it out and it was pretty fast, the battery went empty so I touched the motor and it was pretty hot to the touch, not unbearable but pretty hot, am I overgeared?

If indeed you are using a 380 size motor, you may never find the sweet spot on the gearing to be able to run longer length of time. A short course truck is quite a bit heavier than a stadium truck, and would benefit from a 540/3650 (36x50mm) size motor.

Earlier SC10s came with an 87T spur, and the Factory Team models came with 84T spur gear. I was running my one SC10 with a 3300kv motor using 18T pinion/87T spur gear, and the other SC10 had a 3100kv motor using 19/84 gearing. Both motors were low budget no-name 3650 size. The gearing charts in the back of Associated's manuals are just suggested starting points. They are pretty good, but your motor choice, and driving style are two big factors on finding the best gearing.

I wouldn't run that SC10 with a 380 motor. That's a very underpowered motor for a 1/10 SCT.

If you don't have an infrared temp gun, grab one off Amazon. They're cheap. Keep your motor below 160°F or so. A general rule of thumb with electronics - if you can't keep your finger on it for a few seconds, it's running too hot. But get a temp gun to keep your electronics safe.

But what it the motor is like really powerful, the thing is zoomin

Well, if it works, ok then. But check your temps and adjust your gearing if it's running too hot.

So just to get this straight, more teeth= gearing up, less teeth= gearing down?

So just to get this straight, more teeth= gearing up, less teeth= gearing down?

Gearing up: smaller spur gear / larger pinion
Gearing down: larger spur gear / smaller pinion

Like shifting up or down. Just not possible on the fly.
