OH BOY!!!! Every once in awhile I come back and watch a video that I have seen before but maybe didn't recognize in the thumbnail...... And when I recognize the video, I still watch it again because it's that good. I wish you guys were living a few hundred miles south of where you're at...... It would be cool to have friends as smart and nice as you guys.
Wonderful, thank you.Would be good if you could put up some data. Like airfoil section, CoG, Wing area and loading? Where’s the rudder? How much power does it use? Have you thought of covering it with solar cells? I’d think it would be good for 700W - 1000W worth though you’d increase the weight by 3kg or more.
Beautiful aircraft and great flying. Camera man made common mistake of keeping the video zoomed in close all the time. Might as well had the aircraft just hanging on a string. Staying zoomed out more give some perspective in relation to the ground and the speed of the aircraft. Happy Flying
GrampaKenCanada you made the not so common mistake of telling the Emmy award winning Photographer how to do his job. You want a wide shot? Use your telephone!
Ran , please accept an invitation to our family Rc day at Lagoon Valley Electric Flyers near Vacaville , CA April 28th . Bring some of those show stopper planes .
Like one of the comments below, you keep saying RUDDER ? I guess you could control yaw with differential thrust... I bet on a thermally day it would be scary to watch it fly.. interesting video, thanks for showing...
I think the previous reply-ers missed the actual meaning of the question. "How can it be so stable with no wing sweep?" The answer is a reflexed airfoil. The entire trailing edge curves up slightly from the datum line. Just do an image search for "reflex airfoil". The center of gravity will be much further forward than on an airfoil with a conventional tail. The nose weight provides a fixed force, trying to nose the aircraft down, and the reflex airfoil provides an opposing force that varies with airspeed. Just like any stable aircraft; fly too fast, the downforce on the tail increases, lifting the nose, and slowing it. Too slow, the opposite happens. The downforce decreases, the nose goes down, and it speeds up to its stable cruise speed. Even if the actual airfoil is a flat plate, as in this case, the elevons (control surfaces) will have a slight upward bias, which is, in fact, a reflex.

Totally awesome. Thanks for sharing
Imagine that with carbon fiber spars for added rigidity and solar panels on top... That would be one hell of a long duration flyer.
That was cool as hell, you never cease to amaze me.
Great fun. I especially like the technical discussion on what was being seen. So...when do you start 3D with this thing?!
Wonderful work and flying! Fun to watch this aircraft fly!
that was interesting. I'll pass on the design, but the principles involved are fun to think about. Thanks for another great project.
Wow...love the projects

Wow so cool. Neer thought it flys so good
AWESOMELY AWESOME!
That's awesome!
EPIC!!!!
This seems sort of epic, worthy of greater attention and duplication. Perhaps the limit to its popularity is its need for still air.
this is amazing, and i want one
WOW wtg buddy thats just supper cool
Haha I'm back...love your videos.
So stable without rudder and no swept wings!!
Nice!👍☺👍
how were the control surfaces setup?
That's so cool
it flies it worked and not boring
specs?
Curl? WTF is a curl? Ohhhhhhhh, a helix.........gotcha.
He sounds fun at parties
Excellent spectacular

GrampaKenCanada. I wonder if it was the cameraman that was talking so much.
RCWeaven FPV The persons talking are the pilot, designer & builder and some of his friends.
Remarkable ! Interesting how the wing flexes towards the end . Any idea why it should ?
bravo
freakin amazing , but how do you find CG on it
cool to see the tip vortex, is it efficient?
Where is the CG and which prifile did you use?
What material is this made of? something like formboard??
Oooooooh my Gosh😂 phantastico😌
So.... What sort of result were you expecting from a long, skinny slab of foam?
Try clear plexiglass for a wing
How about a 100 ft version?

That's very big rc plank wing
screw airfoils
Seven 'thumbs-downers' are jealous...because they cannot even fold up a paper airplane.
no sweep in the wings but its still so stable. how?
tdstudd1996 drag and lots of it lol, also differential thrust probably
tdstudd1996 planks can be very stable and aerobatic even. BUT the CG is very unforgiving- it has to be spot on.

Do some stuff!
We did. You are the one watching, what we did on youtube!
Tiplet's?LOL Winglet's maybe?LOL
backseat driver xD
Will somebody make that guy that talks so much drunk so he can sleep it off in the grass ...
Plane?😂😂
Who cares about efficiency high seed is the best slow is boring
