Well, here I am again so let you all in whats really going on. I need a dual Throttle Quadrant. As I have said before I have 2 of them.

 

So here is the PLAN:

Now I distrust USB as when it fails you cant trust the configurations anymore.  So I will communicate via RS-485 between Arduinos, with the master node,

using NASA's EADIN Lite Protocol.

having an Ethernet interface, to talk to the simulator. So far I have 3 nodes:

  1. Master: runs joystick and talks to the simulator via ethernet and talks RS-485 to the slaves
  2. Slave.1: runs Throttle Quadrant, Gear Lever, and Gear Lights
  3. Slave.2: runs Rudder and Brakes
  4. Slave.3: runs Engine Start Panel, Computer Fail-Over Panel

 

  1. Complete Disassembly.
  2. Toss the Base Cover and bottom, I will keep the upper arc.
  3. Desolder and remove all the wire from the switches, we don't need it.
  4. That should leave you with the following:
    1. The Left Shell Body
    2. The Left Shell Rear
    3. The Right Shell Body
    4. The Right Shell Rear
    5. The Right Switch Support
    6. The Top Cover and Wipers
    7. The 2 Throttle Bodies
    8. Long Bolt & tension arm (nut)
    9. 2 white spacers
    10. 3 wave washers
    11. Quadrant center plate
  5. Now Remove and Toss the stupid lever locks and fill the hole.
  6. I want to replace JS1 and JS2 with analog joysticks
  7. I want to lengthen the Power Lever Arms with some aluminum.
  8. I want to add  "gates to the Power Levers, fuel shutoff, and turbo.
  9. I will most likely rebuild the Quadrant base to add room for gates and thicker arms.
