hey guys i know i ask alot of questions, sorry

but im thinking of my next project for the summer. im thinking of makeing a crane. i want to make a clam shelf digger for it too.

now to be true to scale should i make it a tube type boom or a ladder frame?
you think it's ok to use crawler winches for the spools? or should i use something else? sitting at my desk i count 4 channels for the crane. and the big one! how big would be cool? i'm thinking 4 foot tall?

any ideas help or what you'd do is cool. it's going to be a few mouths away but i'm doing the planning so again any help thanks!

Size depends on weight which depends on what you will use to power it. some inspiration

looks like a mix of winches and hydraulics

you will want Robotics 360 high torque servos. Much better then hacking servos and hoping they dont go all twitchy!
