Tamiya 4-Speed Double Gear Box (Left/Right Independent)

I'm testing all sorts of motor gearboxes so the product performs fine for what it's supposed to but the main test here was to see how RobotShop operated and I'm very pleased with this second order, I will be using them for my supply of motor gearboxes whichever model(s) I decide on.

I've not put this into anything perminately, but I've had some fun with the several "toys" I've experimented with. Low cost + high quality = This is going to become a staple for my projects.

Little plastic gears, but for this price more than fair. If you need a bit more rpm use FC 130RA/SA motors from Mabuchi.

I found the quality of the product to be very good and I like that you can choose from multiple gear ratio options. I plan to use this gearbox to build an R/C tank. The only complaint would be that the grease provided for the gears came in a tiny tube and I found it difficult to evenly apply it to the gears. I basically ran out of grease before I could apply it to all of the recommended areas.

Inexpensive and good quality for the price. Lots of gearing options.
