====== Compact collective head ======
 

===== Summary =====

This head is perfect for use with motion platforms, as it can be used without counterweight, or even without the pneumatic mod (although I highly recommend the latter!). Also great as a generic gaming device – its shape allows using it as a throttle lever in single-engine airplanes when mounted to the GUNDE chair onto the Malinda mount at 30 degrees. \\ {{http://hc625ma.org/wp-content/uploads/2019/07/15628064868833158517964134919653-1024x1024.jpg?400 |}}

===== Assembly guide =====

1. Assemble the lever as described in the single collective manual, up to the point of installing part 2 of the throttle frame. Install the compact head instead of it: \\ {{http://hc625ma.org/wp-content/uploads/2019/07/15627933669808738192164808220521-1024x1024.jpg?300}}

----

2. Solder an ISP header to the Pro Mini board. Solder I2C cable to the board as usual. Remove LED from pin 13. \\ {{http://hc625ma.org/wp-content/uploads/2019/07/15627934435157349507168809673598-1024x1024.jpg?300 |}}

----

3. Put 4 M3x10mm screws into the KY-023 board. Use nyloc nuts as legs for the board. Solder a 5-wire ribbon cable.

4. Solder KY-023 board to Pro Mini like this:

GND -> GND next to pin 2
5v -> PIN2
SW -> PIN3
VRx -> A0
VRy -> A1

----

9. Flash the board with its firmware through ISP header.

Uncomment 
''#define CALIBRATE''
and open the serial console, then check all switches and buttons. If everything works, proceed!

----

10. Put shrink tube onto the Pro Mini board, and insert it into the throttle frame.
