RTZAS = Roof Top Zombie Annihilator Slingshot!
Had a day off and made it.
I changed the construction a bit, the stick is now undernath the bands - works better that way.
I get a draw of 370cm = 147 inches. Not bad!
Drawing it out is really easy, you take two steps towards the "fork", load a ball in the pouch, and then you grap the stick and walk backwards. After you have reached the shooting position, you draw out into full butterfly just as normal.
This is absolutely frightening when it comes to power.
Will make the video in time for Halloween!
