Electric Controllable Props

Possibly another option, old fashioned, Aeromatic. Basically no control in the cockpit but sets automatically for takeoff and cruise. Aeromatic.com

I have a brand new Ivo variable/constant speed prop, elec Would suit a J230 or other, Cost $5000...sell $2000 to clear it.

I think Hugh’s Aircraft had a VP prop it fitted through hollow shaft on gearbox and had a vernier cable to adjust. Anyone know how it went

 

We have one that is being fitted to a Rotax 912ULS. It will use Bolly blades. I don’t think any have been made since we got ours from Hughes Aircraft. If anyone has firsthand experience with the system that they can pass on before ours flies, any feedback would be appreciated.

The Hoffmann props have a very good system. 3 position, very light. A spring loaded three step collar gives the different blade pitches.

Unfortunately, no local prop service centre available now.
