Hi anyone who can help,

Im trying to use Phidget servo motor controllers to try to build some flight simulator instruments, im not a software guru hence the difficulty im having. ive downloaded the FS2Phidget software and so far ive managed to get the servo when starting FSX to rotate to one side, im trying to build for my first instrument an airspeed indicator.
My guess is im not to familiar with the value side of things and i think this is where im going wrong.
Does anyone have any examples of setups for instruments that can Help?

Thankyou
