Controllable Pitch prop makers.

[FAST FRED]

I had a great link to a designer that had a list of about 1/2 dozen mfg of CP props.

Somehow I cant find it. Damn.

Looking for a CP that will be efficient at semi plaining speeds 18K with input of 75 to 100KW.

You probably would not get an answer even if you were to send them an inquiry. They completely ignored all my emails when I wanted to discuss using their drive systems. Seems like a strange way to do business, but since they care so little about responding to professional inquiries I would not want to deal with them after-the-sale either ... :(
