Use AI to find the right pinion gear

With the So Dialed RC Gear Recommender, just enter a little information about your car, and we use artificial intelligence to suggest a great pinion gear, so you get on the track fast. A great complement to our Gear Calculator App.

Ideal for:
- Electric cars and trucks in 1/8, 1/10, and 1/12 scale
- On-road, off-road, dirt oval, and drag
- Using foam tires? Cool, just enter your tire diameter

Please note: everyone's car and track is different! We recommend gears based on typical race cars under typical racing conditions, but if you've done something crazy to your car, our recommendations may not work.

Also, our recommendations are a starting point, so after you try the pinion we suggest, please experiment to see what works best for your driving style and your track.

To do further tuning of gear ratios, FDR, and rollout, check out our free Gear Calculator Pro App.

To record your setups, tests, and races, check out our RC Setup App.

5 stars: This is a must have application if you’re building and racing R/C vehicles! I used to constantly waste time trying to find the perfect spur/pinion ratio for the track. I’d find it eventually, but then the track would change or I’d race another brand or model car and be back to square one.

With this app it can be simple. All you need to do is find your R/C car’s make/model, the motor you use or plan to use, then select all the track specifications and boom…you're done.

Whoever developed this app is awesome. Also the developer makes a bunch of other must-have mobile applications for R/C enthusiasts.
