2. Did you remember to set material properties on the compressor and CIMs? Right now you have 11 pounds in CIMs and 4.3 pounds in the compressor, which means everything else shown weighs only ~18 pounds?

3. What are your transmissions made of that you get them down to 1 pound? I'm curious. I've basically found through CAD that the only way to get a shifter in a similar application down to 1.01 pound would be to switch to suboptimal (as I've been told) parts, or like 1/8th delrin or something ridiculous like that. How'd you get this transmission to 1 pound?

If everything's as it seems and you made a 34 pound chassis that does all that, good job!

Well the cams method of turning are different, not the actual block.

Yes all the materials are set. The reason that it is so light is because the upper-structure is made of 1/16in aluminum

They are made of 1/4in Delrin and 7075 Aluminum
