Wouldnt PVA and aliphatic have worked for this build? If so, that would overcome your issue with suitability for less experienced builders. With your impending interstate trip, you may not have had time to wait gor these glues to dry, but others perhaps would. And those glues are readily available.
@@kenkingsflyingmachines2382 it's surprising how much load a strong hand launch places on these things. Catapult launch can be pretty stressful on them too.
You are correct about one thing...(well, several things)...it isn't a child's toy. I ended up using epoxy because the fit of the port dihedral joint left a lot to be desired. It is hard to say what caused that. I suspect the main wing panel got banged either during shipping or my ham-handed extraction from the bag deformed the end. PVA glues require clamping pressure and have poor gap-filling properties. Epoxy fills gaps effectively and requires little or no clamping pressure. So you were right again! My fuselage was unbroken until I broke it...in the same spot yours was. CA made short work of that problem. It's probably stronger now. All of the parts weighed 10.9 grams before assembly, and the finished weight (without balancing) is 11.5 grams, so I think my concern for using heavy epoxy was unwarranted. I can hardly wait to take it to the field. The weather has been hot and calm lately.
@@kenkingsflyingmachines2382 it's wonderful how light these build. There are definitely some inconsistencies in the dihedral breaks, and I haven't yet found a good fix for that, but as you've seen, epoxy solves the problem, and very quickly too if you use the 5 minute stuff. Ive seen foam safe CA used to good effect as well.
So that’s what that glider I’ve been seeing in all of the Polish F1N contest videos is called. Looks great, and the Euro guys and gals make them fly fairly well. I don’t think the Crow will quite fly Yashinsky TIT times, but a beginning F1N flier in the states would get many enjoyable flights from one.
In terms of beginners, this is probably the best indoor glider created. Since it's not a flapper, it's easier to trim, and it puts in impressive flight times for something that doesn't have flaps and isn't crazy light.
I'm so sorry to hear that. A lot of teams have been hit hard with this, and I don't think it's the right response to the situation. Depending on where you are, you should register for the AMA Indoor Nationals in Springerville, AZ. It's at the end of May and we don't plan on cancelling anything there.
We liked these so much we had to find a way to import them! You can get the Crow here: jhaerospace.com/product/crow-f1n/

I honestly haven't had great experiences with bonding foam using most of those glues. Epoxy just works.
Still flying after two years...outdoors.
That's fantastic!
how... amazing
Literally at the kitchen table! With the magic disappearing pancakes
If you watch closely in the various vids, lots of stuff appears and disappears
@@joshuawfinn Ah yes, but if there are spare pancakes about, I'm always watching them closely!
Are plans for this available to the general public or do they have to come with the kit?
Here's some pretty detailed stuff:

The thing to bear in mind is that you can't easily reproduce this plane since the wing is cnc hotwire cut to an LDA airfoil. Not easy to reproduce.
@@joshuawfinn I was thinking of using solid balsa for an outdoor glider =D
@@henryforster8101 ok that could definitely be fun!
@@joshuawfinn If I kit it and send you one, would you micro DLG it like a Carbonette 19?
Wow
Josh, I just started putting mine together, and...is there any reason not to use Weldbond or some other pva? Or is epoxy simply faster?
As long as they'll give you a rigid join, try it. :)
Yeah, I mean the wing weighs 8 grams before assembly...how much holding power is needed?

How can I get a dream with an airplane so tell me pice and where can I get It

@PiterFPV 42 sec is longer than I've done with anything below high Cat III flying, so that's very good.
We had our states canceled due to Coronavirus. Sucks because one of your super protege kits just arrived

@@joshuawfinn Sorry, I'm from New York. Thanks for replying!
Ou mr. Joshua yor explane of wen contrution tha glider it is heard low in the explanation
Too quiet? I'm working on a solution but getting the hardware to interface has been a pain in the neck.
There are foam safe ca's.
There are, and I have used one brand (Bob Smith I think), however not all "foam safe" CA's are created equal so you'd want to test carefully.
So what's the dihedral setting?
It's 80mm at the wingtips.
@@joshuawfinn thanks
Мужик конечно спасибо за информацию но неужели нельзя порядок навести дома?
Not sure what you mean...
Cool, please rate my f1n plane.
Pd:tha fers flight is greid flight
at about 19:30 in this video i believe you can see this model fly ua-cam.com/video/auaR7GzNDKU/v-deo.html
It's *very* popular in Eastern Europe, and for good reason.
Wow
