Hi Steve and Mary, I thought that I would try to see what this glider looks like. Have attached 2 photos of this weird bird [main pic, 003]. Because the file is 3D, any other view can be generated if desired.

Gene... with all the great work you've done for this site and so many plans, I would be the last person to question your depiction of this one, but the trailing edge (main pic) seems somewhat a bit too "straight" to me. Of course, this might be all an illusion because of the chosen angle. This is a highly swept wing, so again, not questioning your work, but... maybe another depiction at an angle that shows off the high sweep to good effect?

Hi Steve, there is a section where the trailing edge is not straight when you look edge on. Around 75% outboard to accommodate the strong reflex. At least that's how I modeled it. And, I have no idea how to build this model as no incidences for the airfoils were given.

Attached a 3 view [see pic 004, also as pdf, see supplement file].

Nice work, Gene, it does end up in quite an elegant shape. I myself was working on&off (mostly off) on rearranging the original diverse parts into a continuous wing - which was entertaining given the vagaries of the original drawing - but you got there first and with a fine 3D view too, so gold medal for you, and none for me :-)

Diffuser tips - cool! The inward angle of the anhedral break provides reflex and yaw stability all in one. Made a few FF like this and they can perform quite well. Also note - the Estes ARV Condor model rocket kit, now OOP, used this on a pair of parasite gliders.

Hello, It seems that the flight is adjusted by moving the flap. The component goes from 36% to 78% possible. The angle of incidence of the flap is not fixed. If you look closely at the plan, the shutters are adjustable. The angle of incidence of the half wings is found by drawing a straight line which starts from the skate and therefore gives the measurement of the angle...?

Olivier, I think you're right. Took me awhile to understand what you were refering to (you use a translator?), then a while to "re"-interpret the plan, as per your comments. It does say that the anhedral tips are adjustable from 36° to 78°, but its still not clear to me how that would be achieved. The only thing I can imagine/figure out is that the tips are detachable, having an aluminum tube behind LE, a small bamboo pin in the middle, and it seems, two hooks at the rear (TE) to secure small elastic bands in order to keep the tips at the chosen angle (up at 36° or down at 78°), and also from slipping out and falling away. Someone has got to build this controversial glider. If I didn't have so much projects on queue and so little time, I would have a go at it. Also, not my usual kind of model.

Forgot to say that in order to adjust the angle of the tips, tips would be removed, the aluminum tube would have to be bent to the desired angle, tips re-attached and rubber bands installed on hooks. So not so much adjustable as giving the buider a choice. I guess the aluminum tube could be bent back and forth a few times before succumbing to fatigue.
RC Yeager - 29/01/2022
YES, my English needs a translator even if I understand the essentials... More difficult to get my thoughts across ;-). I had thought of a bent aluminum spacer. On the other hand, I do not understand the principle of the behavior according to the inclination of the flaps!.
To understand better, I think it is necessary to dissociate the elements of the plan to make it extended. And maybe work on a paper airplane? ;-) or on a flying draft?

And find this number 91 of June 46 for the technical explanations...

Hello, Even in French, I was confused. Going back to the flying wing, I think you have to consider the front plane as a letter M. In fact, it is the outer legs of the M that move up or down depending on the angle of attack. these half wings... I put in % but the value, I think, must be considered in degrees. Does anyone have another idea?
Olivier - 30/01/2022
Olivier... keep in mind that my comments are based on things as depicted in the plan. The crosswise aluminum tube, the bamboo tenon and the hooks for the elastic bands are all there in the plan (see where tips and main panel join between rib no. 9).
RC Yeager - 30/01/2022
RC YEAGER :-) Thanks to you, I just understood ;-) A big thank you to you... Elements that I had not seen appear to me in broad daylight...
Olivier - 30/01/2022
Still, I'd be happier if the bamboo tenon were parallel to the alum. tube group, it would make for smoother assembly, and a bit of scotch tape at the leading edge would help to keep the main wing and tip together. Maybe at the trailing edge as well instead of the original elastic and hooks. At the end of the flying day just pull the tape off and dismanle.
