Correct!  I'm using Phidget servo drivers to make em move, and Bodnar boards
to read the positions.

Winch servo's are fairly cheap over here if memory serves but talking to my
local RC shop guru, something he said put me off using them. Damned if I can
remember what it was though :(

With free access to rapid prototyping gear though, it's relatively painless
for us to make custom stuff and the simpler gauges like RPM, Turn/Slip,
Vacuum et al will be made in-house in ABS.  I'll post pic's as they
progress.

Just ordered a Butt-Kicker too for some subtle 'feeling' in the cockpit.
This is in addition to a powerful sub-woofer bolted under the seat ;-)

The list so far...

2 Bodnar boards  (pitch/roll/yaw/throttle/trim/carb heat/mixture/flaps/read
servo pos/switches)
2 Phidget servo boards  (to drive instrument servos)
2 Phidget Analogue-4 boards (to drive real gauges such as fuel qty, oil temp
etc)
1 Phidget Interface Kit  (starter engaged light/tpndr ident light/etc)
3 GoFlight panels (most cost-effective solution I could find)
1 Bendix King KT96 (dead, gutted, lights up and Ident button/light works)
