I bought a Bernie Warneke "almost constant speed" prop for my Dragonfly in the late 1980's. He made laminated wooden props; most have 5-10 layers. His had 30-35 layers, flexing under load to emulate a constant speed prop.
I can find no record of what happened. It had been in the Tucson area then. Has anyone info on what happened? He was an older gentleman, but I thought he had an apprentice who would've taken over. Need a prop for my Cygnet and would prefer something like it.
