If no one else has replied;
Some years ago I built a Cessna 404 simulator using Simkits CCU and MCU boards/instruments. If you are still stuck I may be able to help you as I think I still have software and handbooks stored away.
Do you use Skype or Viber ?? If so happy to have conversation with you about your project and to see if I can help
I am in Aylesbury, Bucks.
