3:1 Planetary Reduction
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.

Re: 3:1 Planetary Reduction
Don't stare at the planetary animation too long Mark. You'll end up like RW.

Re: 3:1 Planetary Reduction
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!

Re: 3:1 Planetary Reduction
The KW would run the same diffs as the HDX in real life. Clark BD91000 or BD121000. Some of the trucks had Rockwell SPR570 axles but they were not common.

Re: 3:1 Planetary Reduction
got 1 of these a few weeks ago, very simple to add on and produced nice amount of torque. Im getting alot better acceleration now and driving off road dosen't even slow it down
