So I’ve seen quite a few post recently on how to find the right gearing for a RC car. So here ya go.
*As a reference use the stock gearing of your RC as a “mid point”*
If you’re trying to go slower. You’ll want to add a bigger spur gear and smaller pinion gear. What that does is it makes the input (motor) speed reduced and with the bigger spur gear it makes it slower to turn a full rotation. Also may I add. This will deliver more torque and less speed.
If you want a faster RC car. You’ll need to add a smaller spur gear and a bigger pinion. Which now the input (motor) is bigger than the output (spur gear) it makes the output (spur gear) move faster which makes your RC go faster. Also may I add. This will deliver less torque and more speed.
HOW DO I FIND THE RIGHT GEARING FOR MY RC?
Finding the right gearing for your RC car is crucial. Because if you put too big of a pinion and too small of a spur gear. You can overheat, wear drive terrain down significantly, smoke your esc ETC. but if your under-geared you may have too much torque and not enough speed at all.
I personally would…
1. What type of RC are you trying to gear
2. Are you trying to go slow or fast
3. Get ~4 different spur gears
4. Get a little pack of a wide variety of pinions.
Make sure electronics aren’t overheating or cutting out. If that is an issue. Gear down.
Gearing can be frustrating. I would also recommend running each type of gearing to find what works best for your RC. Make sure to follow this guide when you’re new to gearing. Good luck!
