nice! Have u finished ur project?

Nope, its on the back burner for a few weeks.

I'm more focused on my ZZawd right now besides I feel I have the ZZmt pretty much under control.

I hate the way I did my axles and may have to make some real ones for it.

Your design is interesting although it would be able to pull stumps with that many gears.

I like the design. It seems rather quite sound. I'll go out on a limb here and say that it would work most definately.

I'm not sure what you are gaining with the 4 extra gears other than additional friction. There is no gearing up or down in your configuration that will provide extra torque or speed with those extra gears. Perhaps I'm missing something.

Dude you are awesome.

I don't think I'm ever gonna get back into these things.

Keep an eye out for my post down in the selling area.
I've got a few new MTs and a bunch of accessory kits, not to mention a ton and a half of stuff leftover from the MS/Zip Zap days.

What Sea-to-Sky has not told us, I think, is that the gear sets are free to turn on the shafts. If I am correct in my assessment of his arrangement, then he achieves a good gear reduction at the end, much like the gear arrangement in the ZZSE servo.

What is not clear in my mind is the output gears. It appears that he has two small pinion gears turning eachother, which would mean the outputs to front/back and back/front, as he labels them, would be in opposite directions.

If I were building this gear box, I'd fasten or bond the final gear to the shaft (permitting the other two gears to spin freely on that shaft) and use the shaft as the output in both directions. To couple the output to small pinion gears, as he does, in part defeats the gear reduction.

Does any of this make sense?

Yes, I think I see what you are getting at and I agree about fastening the last gear to the shaft.

impressive
 

ull need to lower weight from that much for more power use a dremel and put holes in sections on each gear like a spoke

What is your estimated weight savings in ounces or grams by "spoking" the gears? What percentage would that be of the entire average weight of the truck?

chilli

well varies
 

most likely .5gram of ea gear u can reduce more by cutting in lines but do not cut close 2 teeth and gear conection

Have you "spoked" your wheels?
