3DSets Belt-Drive Motor Conversion & Speed Gearing

Converts the 3DSets belt-drive gearbox to use a more powerful and widely available 36mm+ can RC motor rather than 3530 outrunner motors, and includes new optional pulley ratios for higher speeds. New pulley ratios use the same HTD-3M-144 belts. The following options are included:

1st stage: 30t pinion + 24t pulley 5 OR 24t pinion + 30t pulley 5 (flips to overdrive vs stock 0.8 ratio)

AND/OR

2nd stage: 25t pulley 5 + 30t pulley 4 OR 18t pulley 5 + 36t pulley 4 (0.83 ratio vs standard 0.5)

These can be used additively or individually (i.e. swap only the 2nd stage for very slightly higher overall ratio, only the 1st stage for a larger increase, or both for a relatively tall ratio.) Using the higher ratios in both stages, you'll need a big motor and big batteries. Top speeds currently unknown.

8mm+ grub screw recommended to hold the pulley to the motor shaft.

Also includes a servo mount file for the Sakura 240 to support up to a 36x50 motor. Should fit under the hood if wires are clocked correctly, and it shouldn't contact the servo horn, but clearances are very small. 

All of this is experimental. This greatly increases the chances of complete destruction. Use at your own risk.
