iPhone app RC-GEAR

The calculation of the final drive ratio of the RC car is.

[No.
of spur gears x No.
of Pinion gears x Secondary gear ratio]

You can calculate with the above.

It is very troublesome to calculate every time, so I developed this application which can be used offline.

When set to low gear (high numerical value),

- Acceleration (rise) is fast.

- The maximum speed does not increase.

- The motor load reduces.

- The running time of the batteries will be longer.

When set to high gear (low numerical value),

- Acceleration (rise) is slow.

- The maximum speed increases.

- The motor load increases.

- The running time of the batteries will be shorter.

However, please note that some motors and ESC have their own recommended gear ratios.,
