This arm is for colecting the bins and empty them in the truck. It is in Beta, soo it isnt fully done and I am working on it.
CONTROLS:  activate 1 and do VTOL up to get in range.
 activate 2 and use  Trim down to open or close the claw. 
activate 3 and use VTOLto lift the arm up, or let it go down.           
I hope someone can use this design, the finished version is comming.
