Re: pic: 2011 Drive Prototype
A few questions:
1. Are the cam tensioners any different than the standard 254/968 style? Based on their mount location it doesn't look any different, in which case there's not much point to keeping them "a secret".
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!
