|  Ultra Compact Gear Reduction Unit  Above is our the final prototype version. We will start production after we go through a few more testing. The gear ratio is 4.3:1. This custom housing can be expanded all the way to 200:1 gear ratio if needed. Any other other gear ratio will be made base on request. A picture with it mounted a 540 motor will be posted tomorrow. Now we have gained a lots of experience in making micro size gears, we will start designing a 3 or 4 speed full metal tranmission. A prototype will be made end of next month. The retail price will be 39.99 per unit. You will get the Ultra Compact GRU and a custom pinion gear for the motor. Specs: Overall diameter: 47mm Height: 18mm Output shaft diameter: 3mm (with a flat surface for mouting standard RC pinion gears) Total gears: 4 Last edited by rc4wd; 09-19-2006 at 09:11 AM. |

| Ok, now if I'm not mistaken you can bolt up motor right to that, then that will bolt to where the motor would have bolted into the tranny? If so, I will pick one up as soon as they are available. My tlt may need some more grunt. |
