GRU for Tamiya 3 speed gearbox
Ok, I guess its the time I open a thread for this unit hre in vendor pages so everyone can find it if needed:D

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.
I give 1 year waranty on this product, so if you brake it, just let me know how you did it, what broke and send a photo, so I can improve the product. In return, I end you replacement part for free;)

We in Russia have a Prime Minister Dmitry Anatolyevich. I will ask him to deliver the letter. How to find Doggy? Does the FBI know where he is?
