So make more of those ... the prospect of not changing tools manually would be worth it for me. That and it'd look pretty awesome.
i could murder you jonathan!!

the power and switching would be the easy part... just make interupted slip rings driven by one ESC

the tricky bit is making the capstan rigid without it weighing a ton and having a masive overhang

i dont believe youv got me thinking on this one... iv also got a million and one things going on "i must get some sleep at least once this week"

it would be nice to have a 5x tool change though i could go down the pub swill a couple cut the lawn smoke a couple have a manicure come home change slabs have a couple of hours sleep.............zzzzzzzzzzzzzzzzz............

i may ponder this some more but i can sniff a bit of a blind alley coming on
