 ===== Summary =====
-This is a scale Bell 206 collective head! It's made using photos with measurements, so should be really close to the real one. It's quite simple, but really has everything you need to fly helicopters (if used with the lever body with a physical throttle latch).
+This is a scale Bell 206 collective head! It's made using photos with measurements, so it should be really close to the real one. It's quite simple, but really has everything you need to fly helicopters (if used with the lever body with a physical throttle latch). This head supports the mode switch function for the starter button and GOV RPM switch.

-. Prepare the top panel of choice and insert switches in it. Cut the top off the MTS-123-E1 plastic cap so the scale cap will fit onto it. You can use a black marker to paint the cap if its not black. Insert the PBS button into its socket, glue the decorative cover on top of it and then put the scale cap on.

+. Put everything into the box, do some cable management so that the aluminum pipe won't damage wires when the head will be put onto the lever. Push onto the Ethernet socket so it will protrude slightly from the bottom. Glue the socket cap part with some cyanoacrylate and level the socket with it so it will look good. Carefully fix the socket in place with hot glue.
