I got a hanging scale from my brother and officially weighed it.
The backpack weights 10kg/22lbs, and each shin weights approx 5 kg/11lbs. It is about half the weight of the skeletronics system (est 45kg), and fairly easy to move around if I remember to glue everything *pop*!
I'm trying out an idea for the feet that could prove to be revolutionary towards stilts and future mechs. If so, I'm tempted to start a "Kickstarter" and brand it as a piece of sporting equipment.
This would be hilarious because I could sell one of these things for 3% of the skelectronics price and still make a tidy profit! I'd be that sneaky bugger who takes an idea and makes it cheaper and better, eg Apple turned the PDA into a smartphone.
RIGS here we come!
