 This is a semi-scale Bell 407 style head. This version is modeled after the 407GXP switch panel, as it has more buttons on it than others. From what I've seen, there are a lot of variants of this head with different buttons on it. Proportions should be accurate, with some minimal deviation needed to adapt the head to the existing simchair MKIV collective lever body with a physical latch.

+Files for this collective head are distributed for a humble fee to support further development of the project. Please consult with the [[simchair4:misc_donor_shop|donor shop]] page and contact me to get them.
+===== Features =====
+This is a semi-scale head with the following features:
+  * 2 3-way switches with middle buttons support (3 joystick buttons each)
+  * 4 buttons with mode switch support (12 joystick buttons)
+  * physical hat switch respects mode switch position and is mapped to 3 virtual hat switches
+  * this head is intended to use with levers with a 206-style lever body and a physical throttle latch
 ===== Assembly manual =====
-. Solder wires to the hat switch. The ground wire is the top-left (black) wire. Note how it's slightly closer from the center pin than the other one. Check that every direction of the hat works with a multimeter, connect it between the GND pin and each of the other pins.

+. Solder an ISP header to Arduino Pro Mini board. Solder a 7-wire cable to an Ethernet socket. Connect it to Pro Mini board as follows:
+^ CONN POINT A      ^ CONN POINT B ^
+| ETH SOCKET PIN 1 | VCC |
+| ETH SOCKET PIN 2 | GND |
+| ETH SOCKET PIN 3 | SCL (A5) |
+| ETH SOCKET PIN 4 | SDA (A4) |
+| ETH SOCKET PIN 5 | Rx |
+| ETH SOCKET PIN 6 | Tx |
+| ETH SOCKET PIN 7 | DTR |
+. Fix everything with hot glue. Put the Pro Mini board into thermal shrink tube or wrap with duct tape. Add some cable ties where needed to organize cables carefully.
