3:1 Planetary Reduction

[Claus]

I bought one of these off eBay, haven't done any testing with it or anything but seems like a nice reduction if anybody is looking for one. It is a planetary vs the spur design offered by RC4WD. $20.00 plus shipping.

Cool unit, maybe I will try to order few to try. 3:1 is not much, and I dont like the fact it goes directly on the motor, as it puts more torque on gears inside tamiya 3speed.
But i would like to have few sets of this gears to combine and make a bigger reduction or a nice planetary 2 speed gearbox!
