By popular demand: winglets. Actually looks cooler with them on.
That looks… Superawesome!!! =)
Does it fly any better?
I don’t know if it even flies yet. Soon. I’m sure these will improve flight characteristics.
@Andre_Roy , I admire your self control. There is no way I could resist sending this thing airborne. Keep us posted. Looking forward to hearing how this goes.
Sweet, nice job. Looking forward to the first flight video
Thanks guys, I really appreciate the interest.
I had another flight attempt. The sling works well for launching. I’m making an adjustment to the thrust angle and will go out again next weekend weather permitting. I find I was too aggressive on the positive pitching moment from thrust in my design.
For this prototype I’ll change the thrust angle, but in the next revision I’ll bring the whole motor down to closer to the chord line.
So first flight without catastrophic failure? That sound promising!
Congrats. If it’s in one piece and can still fly that sounds fantastic. You fly around the pattern or more of a Wright Brothers flight. Would love to here a story.
Yup, nothing broken. Motor mount back plate came off on impact at the glue joint. Easy to repair. Sling works well. Third time’s the charm.
The thrust line on this 3d printed flying wing is similar to OpenSwift’s. Notice how it pitches down during low speed hand launches. They’ve done well with the bungee launch. I think you need to build up enough speed to generated aerodynamic forces to counteract the pitching moment from thrust.

We have started printing an Openswift here at Printrbot! Nick, an employee and our resident RC guy is printing one at home too. He wants to use some shrink wrap style skin instead of balsa… We shall see. I think we can modify the design to be printed on a Plus since there are so many more out there than the Go Large model. This will be fun!
Thanks, Andre!

Sweet, it’s lonely having the only one ;). Ask questions! Let me know how I can help you folks out.
We sure will! I’d love to see this model get some traction!
Brook
Me too, my plan to gain traction is to 1) demonstrate that it flies, 2) generate “How to assemble” build videos, 3) Generate a formal “Homepage” for the project, 4) profit.
