Yeah we did work on the idea of using sockets and brackets
initially.
But the thing is that we have to keep the frame weight below 10kg.
As dumb as it may sound, those sockets and brackets as a whole add
lotsa weight to the chassis.
As it is, we already have an overweight chassis, and we're
scratching our heads furiously trying to figure out how to reduce
weight without compromising structural integrity. We've cut down on
the redundancies, and are using a smaller safety factor, but it
still doesn't seem to be enough.
Carbon fiber is a big no-no, considering our limited budget of just
$1500. So we're pretty much stuck with aluminium.
