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.
