hi I am in the process of buiding a flying crank ghost out of an old computer desk (the kind made out of lightweight tubing). I am viewed many directions inlcuding tutorials on this site. It appears the pulleys are arranged in the shape of a triangle. Does anyone know the dimensions of that triangle. From what I figured 30-inches looks right. Any input? Thanks!

Are you asking for the dementions from pully to pully when the arms are stretched out?

pulley to pulley (to pulley)

I think it all depends on how long you make the arms. I had to adjust mine out a bit further than my original angles.

You have seen the build instructions on the phantasmechanics site, right?

I think 30 inches for the arms works...........and about 20 inches back to the head.............its really cool how much you can play with it..........I tried alot of diff ways before I got what I wanted..................try making a rig and using your hand or something to see if it would be better tighter or farther apart...................good luck
