(Yes it is!)

Another recent incident has prompted me to throw this out for review.

Just wanted to touch bases with everyone concerning our hangar doors. Over the last couple of years too many people have shut their hangar doors on their plane. It is usually the tail and a few wings. That means we are leaving our planes way too close to the door edge whether it be on the inside, but usually these incidents happen when the plane is on the outside of the door.
 

Keeping it simple and effective for the common setup

Let's discuss prop pitch and how it affects flight characteristics. It can help flight characteristics or it can hinder. I'm often asked; What's the correct prop pitch for a specific plane? There is no single answer as many props are available to us today for Rotax engines and for different fuselages. There are, however, some commonalities and that is where we are headed in this article.

Certain principles do apply in either the 2 stroke or 4 stroke engines, although the numbers will be different, as with most ground adjustable props. This article won't get into all the designs, blade twists, angles, thrusts, shaft powers, etc...etc. Whoa, just thinking about it puts my brain in a tail-spin. We are going to keep it simple and easy to follow. I am going to use the Rotax 912ULS as an example.
