Been a while since I've posted on this thread but Lynx is finally underway, got everything but the drive motors and wheels so I have plenty to be getting on with. The chassis material is 6082 aluminium u channel ( 5mm thick for the main body and 3.5mm for the rear spar), I'm going to have to drill some weight out as it currently stands at 1.4kg, I think the last picture gives you an idea of how I'm going to lose the weight in style.
