Devens,

You will have to report how the different props do on the .91fx. I have the same engine, and am eager to hear which prop performs best for you. Are you using a Slimline Pitts muffler?

Question:

Been doing some research on smoke systems and I have heard that some guys are using a needle valve on the inside of their muffler to disperse the oil in a fine mist for better smoke. Anyone tried this? If so, what kind of needle valve are you using. I was thinking about calling Slimline and seeing if they make anything for this.

I had posted that my Skybolt was in pretty tough shape when it arrived, and that I was missing some parts. I am happy to say that I called Great Planes and they are taking care of everything. They are sending me some new parts and a new lower wing. The lower wing was the only thing I was unable to fix. Kudos to Great Planes excellent customer service!
