Hi All:
I'm Rol Klingberg. I have been a pilot for 45+ years and I have flown every type except jets. I'm also trained as an aero eng. I'm currently retired from the aerospace industry.
You may have heard of me from long, long ago. I am the designer, builder, and pilot of the original Klingberg Wing foot launch sailplane. I'm also the former owner of Future Flight R/C models which included the 2 meter Klingberg Wing. Maybe some of you owned one as some point.
I joined this group to share with you my new project, the Klingberg Wing MkII. The goals of this project include:
1. High performance - L/D of about 35/1
2. Safe handling - gentle stalls and spin resistance
3. Foot launchable and landable - empty weight around 100 lbs (or I won't be able to launch it)
4. Can be home built and easy to repair - no expensive tooling required
5. Can be built in short production runs so clubs can build several at once - tooling that is usable for short production runs
6. Affordable - material cost around $10K in current dollars
7. "Car top" transportable - no trailer required
8. Single person assembly, even at "rough" launch sites
I have been working on the current design (on and off) for about 10 years. I have spent a lot of time on the stall spin issues, dynamic stability, and weight reduction. The design is a flying wing of composite construction with a wing span of 15 meters (standard class sailplane). Wing area is 150 sq ft. It has flaps and elevons for control. The wing will have three panels on each side and a small center section. the longest panel is 12 feet. Control is via side stick with belt/gear/torque tube drive system. I have started construction of the prototype and the winglets are complete.
I am documenting all of the development and construction activities on YouTube and Patreon at the following links:

Full technical details of the design are/will be presented on my Patreon site for anyone who becomes a Patron. Those folks will also receive first access to everything I post and will have access to my upcoming podcasts. Anyone who becomes and stays a Patron for one year will have their name applied to the prototype aircraft so in a way they can say they "flew" with me on the first flight! I hope you will visit and give serious consideration to becoming a Patron.
If the videos leave you "wanting" and you have questions for me, you can reach me via YouTube Comments or this web site.
Thanks for reading, wish me luck/skill, and please fly safe!
