I am building a nerf turret and I need good servos that can limit how far the turret moves. I saw some on Youtube and Online that use the MG996R but I bought four of them and they did center or limit their travel. I need 3 servos for the best quality and price. Thanks in advance.

I want to get the spektrum dx6i but it has to be able to get 2 receivers running at the same time. For my tank one receiver for the top part and one for the turret that way it can spin 360 degrees without stopping. Can it do it? And can I use both sticks to celf center?

I bought the FS-i6S and I'm new to it and to the rc world so I want to mount servos to control my nerf gun, turret style. But I need good servos that will move it up/ down and left/right and yet are fairly cheap. I want them to return to home and have limits on how far they move. If the FS-i6S will even do that. Thanks in advance.
