Hi Snoop,

The pieces that you are looking at in the servo tray ( V shaped an straight w/holes) are used to mount the servos into the tray. The V shaped one will be cut out, and once you insert the servo, you will use these on the underneath side, to "sandwich" the servo into the mount. You will insert the screws directly into these pieces and the mount.

For your servo arms, yes, you will just need to cut off the portions that are not needed to configure the servo arm as the manufacturer suggests.

The numbers on the arms do not represent degrees as much as they are telling you where you are off of 90 degrees. Lets say that you use number 1 as a starting point, number 1 is servo movment at 0 or 360 degrees. Then number 2 will be servo movement at 90 degrees, number 3 will give you servo movement of 180 degrees, and number 4 will give you servo movement of 270 degrees.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.
