I could be wrong here and if so you can call me a

and tell me to shutup but the middle picture that you just posted looks to me like the servo needs to be rotated 180'. Your arm is exactly strait with the servo at neutral. If your going for 3d throws I would think you would want it offset a bit so you can get max deflection when the arm is at 45'. JMO

Ok i will shutup now. :7aa:
