HI Pater, Hmm, I'm afraid I'm not seeing it. Too dense I guess, haha. Not seeing vacuum-bagging a space-frame as one piece nor the individual hub parts individually - they're pretty geometrically complex with a lot of fairly thin-well protrusions. I did do a little envelope-math and strength aside, assuming similar material volumes, going to prefab CF links would cut weight by well over 100lbs which is pretty significant. But at the price of about 3x the cost. I need to mull this over for a while, but it sounds like a good idea for the 3rd prototype.

Ok well thanks for the information, it's been pretty helpful.
