OS 91 VR-DF ducted fan engines and fans have been replaced with a single Super Tigre 3000 engine. It now takes off in 50 feet, and flies at 1/3 throttle. It is also a LOT quieter.
Great looking machine. Is this a design of your own or did you build from plans? Am interested in building one to learn more about flying wing airfoils. Thank you for posting the vid!
big difference with a prop in this case,maybe a single turbine?

Cool. I just watched your DF vids and thought it was WAAY underpowered.
I'm designing one right now about the same size.
What Airfoil did you use ?
