Years ago, Graupner used to market a variable-pitch propeller. This unit used a separate servo and supposedly worked just like the real thing. Whatever happened to them? Were there any problems associated with them (shedding blades or runaway RPM etc.)?
Does anybody do something similar now? I have in mind to build a turbo-prop model and it doesn't seem right to use a fixed-pitch prop.
Any suggestions welcome - thanks.

I don't know in which year it was, but I believe to remember Hanno Prettner used such a system for a little while. I think the main problem was (it was before sophisticated computer radios) to pilot it, as you had to set throttle AND pitch. A constant speed kind of system is almost required to fly an RC variable pitch prop.
Look at MEC thread, what those guys are doing is just incredible !
