GRU for Tamiya 3 speed gearbox

[Doggy]

Ok, I guess its the time I open a thread for this unit hre in vendor pages so everyone can find it if needed

So this is a Gear reduction unit bolt on for Tamiya 3 speed gearbox, fits right in your truck without moving any stock parts. Case and gears are 3D printed, metal parts are machined, and it uses 4 standard tamiya size ball bearings. This unit gives you almost 6.5 times slower output, so you can keep your stock motor, and still use your MFC and get much more pulling torque, scale speed, and more battery life.

Here are some basic photos of the GRU














And here are some fresh photos of the last updated version. It now has pressed metal thread for middle bolts, updated hole for shifter shaft so it fits old and new versions of the gearbox.





Price for this unit is $50US and shipping is $12US worldwide.
