I bought the Twinkie last weekend, having worked out some time ago how to get the PMS50 GTN750 Premium autopilot working on planes without an autopilot. The Twinkie now works perfectly with the PMS50 GTN750 autopilot (or AP keyboard commands) and has had a few other upgrades and improvements too:
Tiger’s Shrike PA30 Twinkie mod
Features ground handling and flight performance improvements.
Fully compatible with all third-party liveries.
Simply drag and drop the “tiger’s pa30 mod” folder into your Community folder.
Flight improvements:
Flight dynamics calibrated to 169KTAS @ 8,000ft with 9gph (each side) fuel flow.
Engine power curves updated.
Constant speed prop logic updated to modern flight model.
Weight and balance adjusted to achieve greater stability and control in flight.
Ground Handling improvements:
Rudder re-configured to create more yaw than roll effect.
Various weathervane effects and associated forces minimised on the ground.
Take-off and landing is now possible in up to 20kts crosswind.
PMS GTN750 Autopilot (payware version only):
Integrated compatibility with the payware PMS GTN750 menu bar app.
Fly a full IFR flightplan with ILS or RNAV approach and landing!
The PA30’s invisible Autopilot can also be used with the keyboard only, see the Readme for further details.

Shrikesim’s model has some very nice details and features, including:
Co-pilot avatar
Opening cabin door
Animated elevator trim tab
Cabin floor hatches to access the circuit breakers and emergency toolkit
If you can slew to the rear seats, the co-pilot’s seat can be folded forward which makes the co-pilot avatar disappear
The gear warning beep is throttle controlled only and sounds when the gear is up and the throttles are lower than 10" MP - extending the flaps with the gear up does nothing.
One note for livery artists - the chrome spinners seem to be baked into the model, I could replace the static (engines off) spinner textures but they changed back to chrome when the engines were started!
