The objective of this task is to create the trim indicators for all 3 trim axises.  It should interface with a PC via USB using a PIC18F4550 microcontroller.  In turn the USB data should be interfaced with Flight Simulator using SimConnect.

 

 

 

The construction are done in several parts:

The USB controller is a PICReady board modified to work with USB. It uses a PIC18F4550 to interface with USB and with the 3x r/c servos.

1.  Three radio control servos is required for the trim indicators.  Go for the small servos because of size restrictions.  Below is a photo of the 3 x 8 gram r/c servos used to drive the trim indicators.  You should be able to buy them from any r/c hobby shops.

 

The case was made out of Aluminium on a CNC mill. The photo shows the 3 servos mounted in place.
