I am slowly assimilating my RCExplorer.se / David Windestål tricopter into a 3D printed version.His design is heavy on zipties, but where I am, I can only find the cheap kind that break before you even tighten them..I have yet to redesign the tail section or mid body section. I think a mid body section that folds more like a tripod would be cool..I also plan on adding things like a prop shroud so that if I run the thing into my face again, it will cause less damage. :DFor Reference see: http://www.rcexplorer.se/projects/tricopterv25/tricopterv25.htmlPrint, Test, Come up with Ideas/Improvements, combine to make (even more) awesome tricopter...The current vibration mount is currently designed to use fuel tubing around a 40x3mm screw to isolate the two surfaces.The arm locks need two 20-30x3mm screws each, and mount to the body to hold the arms forward. A tripod design would likely eliminate these.(See thing:9094)
