Perfect for a quick buildReview by Steve
Bolted to a piece of acrylic with a nylon bolt skid. I had to play with the balance because the motors are quite far back from the axle, especially in "high" speed configuration, causing too much friction on the skid. One motor gear has a split making that side a bit noisy. Driven by a DRV8833 with a single 3.7 V Lipo.
Would like to try with the "sport" wheels

Works great as replacement on Tamiya Tank crawlerReview by Dan
We have a mini Tamiya Tank but as one motor drives both treads there's little point in turning it into a robot because it wouldn't be able to turn...This gearbox has the same width and profile as the original gearbox so it was easy to swap it in.

Works as promisedReview by Vincent
I'm using this gear set for a robot heating duct crawler I made to video inspect my ducts. Using it with RB-Tam-26 Tamiya narrow tire set, although I hack sawed down the wheel shafts by 1/2" to give the crawler a narrower profile.
The gear box and be re-assembled, if you are unhappy with the initial gear ratio. There are 3 configurations, but only 2 different gear ratios.
The only con, is the motors run at 3V. Keep this in mind if you are trying to hit a specific speed. But at this low voltage, you get more current loses. Otherwise, would have given it 5 stars.
