installing tail wheel spring/ angle of incidence
|
Jim,
Short answer: 7.8 degrees ground angle of attack when unloaded. My measurements were taken along the chord at BL50 on each side (left and right sides for both the wing and canard).
Since the tool measures the incidence angle at a number of points along the chord, the angle ends up being an average of those points (as compared to the WL on the original plans templates).
Your left and right canard vary by about 0.5 degree (left side has a higher angle), and together they average 6.76 degrees. Your main wing left and right are the same and average 8.8 degrees, so the average angle for the plane as a whole is 7.8 degrees, and your decalage is about +2 degrees.
If you have any questions, let me know.
Cheers, Jay

Jay can you tell me what my angle of incidence was when you measured it.

So Guys,
Thanks a BIG BUNCH for your input!! With your help in this thread and what I have found in other threads on this site, I'm feeling pretty confidant that I have set my tailwheel to give me a good ground AOA. Just have to wrap it with glass where it meets the tail and tweek a few other things, then on to the next part. I've added some pictures of my little journey and how I did it in my photo album Cheers |

Looks good. One little thing to keep in mind, as you raise the tail, the propeller gets closer to the ground. Sam On Mon, Jan 16, 2023, 2:29 PM Mike Steinsland <MIKESKUSTOMS@...> wrote: So Guys, |
