Cheap TRX4 Clone 2Spd Transmission

Описание к видео Cheap TRX4 Clone 2Spd Transmission

Hi guys,

I ordered the cheapest TRX4 clone 2spd transmission I could find for $40 Cdn. The output gears are metal and the insides are plastic. Fit is not quite perfect but useable, overall pretty good for the money. Shipping only took 10 days to Canada (crazy fast). If you need durability try a genuine unit from Jenny's RC for about $65 cdn.

Gear Dimension Calculator (Changing pressure angle does not affect overall diameter so just plug in something between 1 and 45): https://evolventdesign.com/pages/blan...

Do you drive to wrench or do you wrench to drive?
