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.

What's the difference between a planteary and
D spur??

Spur gear is like this;

Planetary is like this;

Don't stare at the planetary animation too long Mark. You'll end up like RW.:rolleyes:

Reg didn't that KW you and the wife were playing with have planetaries in the rear?

Must obey the sun gear...

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!

Leave my wife's rear out of this.:cop::lol::lol::lol:

Re: 3:1 Planetary Reduction
 

Well ok but you didn't answer my question.:D:p

Re: 3:1 Planetary Reduction
 

That real Hayes HDX? https://www.youtube.com/watch?v=AWoqq61WXGg This? If so, yes. 91000 Clark rears.

Re: 3:1 Planetary Reduction
 

Yes, thanks that's the one. All I could think of was your big KW and was at work, didn't have time to search.

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.

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
