A New CANARD…


Well, for me anyway !!!
Gentlemen and fellow fliers , due to my habit of taking junk mail and folding little paper airplanes out of them to toss off the second floor balcony ( the Rutan test) . We went through a lot of the same old designs , but this one was very interesting . So interesting we decided to make a Foamie' out of it .
Starting with a nice STRONG folded triangular fuselage , ultra simple construction , and the fact that it really glides Great ( from the balcony ) makes it attractive for a quick weekend Foamie build .
I’m working on the plans right now and will post them when finished. I still have some Blucor and it should be a very Quick build … ;D

Here’s pics of the “paper model” …

Nice!!

I've heard the tall tale of fighters being designed on the backs of envelopes but never out of the envelopes themselves.

Just to explain the logic of salvaged paper planes , think of it as saving Foam while the experimenting goes on.. This way I can experiment with hundreds of models without using up my precious Blucor stock …

Now , lets talk about that triangular fuselage. For years now we’ve experimented with foam fuselage shapes , mostly trying to improve the strength and stiffness of the structure . Turns out the triangular fuselage is easy to make and the strongest of all the shapes … AFAIK Not the prettiest of structures , but strong and light , and requiring no internal bracing …

Woo Hoo ! A new design from GPW ! I can't wait. I even have some ModelPlaneFoam staring at me - just waiting for the gentle touch of my scalpel.

First decision , do we want to “fold" the triangular foam fuselage , or do we want to to cut three separate pieces and glue them together …? I’s a simple structure .. All how we want to put it together .
If we cut it and angle the cuts right ( @ 45 degrees) it should fit perfectly together …If we fold it , a “window screening tool” or similar would be handy . ( and a little packaging tape )
We’ll make both and see how it works out .

Here’s a drawing about “folding the fuselage “ . It could be suggested running a "blunt tip" or window “screening tool" to score /compress the fold lines for easier folding . For bare foam , I’d suggest running packing tape on the Outside of the fold which prevents the foam from tension splitting , and protects it during flights .
The tape also works for the paper skinned foams too .

Folded fuse. easy and rigid. It's a tight fit inside the 2" sides in fanfold. Battery may have to go on outside?

LD&D, That looks real GOOD !!! If you don’t have room a bigger Fuselage ( 3” ) may be better . We always put the battery on the outside bottom so it could slide off in a crash and not take the nose with it … We never had any problems with that ...

Will make it work. Just a heads-up to others. Anxious to get it together. Maybe 2 1/2 " would be adequate for 950 mah 3s stick pack.

OK, That's COOL … Since we stared off with a paper plane , there’s plenty room for Improvements !!! Did you test glide it yet … The CG should be ~ the front of the wing … test gliding is the best way we found to establish the CG. Tall grass or into the sofa …
