Making a Sonex Faster (Speed)

Interesting post on Facebook. https://www.facebook.com/1728629080/vid ... 012830445/

Aft fuselage to wing root fairing tuft test with and without fairing with preliminary results.

Warning, the FB group seems to have a very different focus.

Sounds very much like a topic that has already been discussed on this Forum

The usual suspects. 5 to 10 mph in cruise, improved elevator effectiveness at low airspeed, and stall speed reduction via aft wing/fuselage root fairings.
We've all seen these kind of claims before, however, he provides photos and videos of some tuft testing of his Sonex with and without his fairing. There is a definite improvement in the airflow. So there may be merit in the claims.

Thanks!

Any chance you might "lift" the video from the Facebook and make it available to us conspiracy theorist.

Without wing root fairings

With wing root fairings

To my untrained eye these don't look all that different. Too bad the mod is not pictured.
