Nonono, this is a constant speed prop. A fixed pitch prop is lighter, cheaper and in a small speed/power/altitude band, more efficient than a C/S prop.
A C/S prop gives you much better take off and climb power, acts like a break when you want to come down quick and is apart from within the small band mentioned above, more efficient than a fixed prop. The fuel savings can many times pay for the extra cost of a C/S prop during its life time.
Another significant advantage with a C/S prop is that you can run it at lower rpm for a chosen power especially at higher altitudes meaning that you can have a quieter cruise.
Now we're talking! Beautiful!
ReplyDeleteDo I remember correctly: you went for a fixed pitch prop? Is there any other pros for that, besides cost and possibly less maintenance?
