This is a single engine collective with head support! It is a successor of a twin 412 lever (https://www.thingiverse.com/thing:2747131) with some improvements. Throttle turns 200 degrees. Its outer diameter was increased to 40MM, like in a real Huey. This allowed for a cable channel to be fitted into the throttle frame. Another very important upgrade is a new, improved tensioner. I have added rubber bands to it to counter the weight of the head, so no matter how much it weights, this lever will move as smoothly as the simple one. I have tested it for a week with a heavy enough head mockup (used my old cyclic grip for this purpose, you can see it on photos) and really liked the results.
The lever is intended to be used with an I2C controller (the latest software is always available on GitHub: https://github.com/hc625ma/simchair_i2c)
A simple calibration process is required for the collective after assembling (look at the video below)

-- UPDATE 03.07.2018
Added idle stop mark (without detent) and software support for it. At the moment it works with DCS UH-1 and Dreamfoil B407. X-Trident AB412 will be added after the release of an upgraded twin lever.
After some testing, I can say that there's no need in the simple collective anymore, use this one instead, it's really good.
-- UPDATE 12.07.2018
Fixed an idle stop mark position. Please re-download i2c_connector_cover.STL
UH-1 collective head development snapshot is available at my site: http://hc625ma.org/
Use the T-568B standard wire order for all your connections (see picture below).
Wires should be connected as follows:
Arduino Pro Mini connections
SS495A VCC -> Arduino VCC
POT VCC -> Arduino VCC
SS495A and POT GND -> Arduino GND
SS495A SIGNAL -> Arduino A0
POT SIGNAL -> Arduino A1
A4 (SDA) -> ethernet cable blue wire
A5 (SCL) -> ethernet cable green-white wire
VCC -> ethernet cable orange-white wire
GND -> ethernet cable orange wire
