Paper airplane replica

Description
So, I was wondering how a plastic version would fly. I used a sheet of A4 paper and folded a paper version first and tested it's flight pattern first for a fairly neutral trajectory before slightly stalling and diving just a little. Depending on the wing section widths it could either div too much from te go or stall too easily. The best is normaly to aim for no stall or a very slight stall. A slight stall normally helps a bit when it goes into a slight dive as it usually pulls out of the dive until it stalls again and dive again. Depending on the height it was thrown from it can fly quite far with this stall/dive effect.
Due to printing in plastic I decided to add a hook under the nose to launch it with an elastic band. So I thought it's only fair to also do some "tool" to attach the elastc band to, to allow for easy operation.
I am still waiting for it to finish printing...so I don't yet know if it will fly

This paper model is actually quite a nice flier. Folded one from the picture. It is similar to the acrobatic flier I was taught as a kid - except that it has the gift of straight and level flight... Thanks! one more design in my origami fleet.
While looking for paper airplanes on Youtube to find the design i use, i found this great channel:
I had a paper airplane book when I was a kid that had that exact model in it. I think I made one as recently as couple of weeks ago. The design stuck with me too.

Instructions
After printing remove the small piece under the "tail fin". You'll see I put in a gap between it and the wings and it should break off fairly easy from the body as I "weakened" that joint. This was only done for print support purposes.
Cut off the 1mm "support" at the back off the hook under the nose.
Prit and fit the elastic hook.STL to anything with 10mm diameter to hold in your hand for launching the plane. Attach an elastic band to this hook.
Now, hook the elastic into the launch hook of the plane, pull and release and watch the plane fly.
Caution: when using the "launcher" you should do it outdoors. Indoors the plane might just break whn it crashes...not to speak of other breakages that might occurr...

Cool! Any chance you could post instructions for making the paper one too? I've never seen that design before.
Yep...no problem at all sharing the design...will sit tomorrow and document it and post it.
I also have a (odd) model that i made as a kid that had some good success. For example, i managed to fly my paper plane on the playing field of a basketball game in a stadium with 50k people. I was sitting really high. I shall made a picture of it because it's hard to explain. It's almost the same as your design, except mine has a heavier nose, shorter wings and flaps for lift.
Is there much weight difference between paper and plastic?
Considering the thickness differences, yes. Paper is very thin (0.1mm or so) on average, so the plastic version will probably not fly (Or at least not well at all).
