6:55 might be the best thing on KZfaq. Flying with family is great. Always makes me smile to see your kids flying with you. They are little now, but give them a few more years and I bet they are going to be some serious competitors.

After 6:53 I added some Six Million Dollar man action sound effects to all of Josh’s throws in my head. Very entertaining.

Wow, I think I am in love! That flies like an absolute dream. While some of that will be down to your expert trimming skills, it is obviously a fantastic design.

This thing is the easiest indoor glider I've ever flown. I can confirm that I tried to kill it in every terrible launch I could think of and it always recovered. Its sink rate is slightly higher than the Cat's Meow, but its easier to get a slightly higher launch with it than with a flapped glider. The Cat's meow did between 1 and 3 seconds better, but that was with me launching the Crow. With a competent launcher, both could get a few more seconds. We had lots of fun with this thing!

This thing flies great! Next glider I build, I’ll try to sand that undercambered airfoil. It seems to work really well.

I got similar results with my crow, but I cannot take it to any flying site due to the COVD-19. I am very happy with my crow and I recommend a super Cat's Meow or a Sweepette if you are really serious about F1N

@kenkingsflyingmachines2382 3 жыл бұрын

Waaah! The tailboom broke on throw number 2. The first flight looked like Josh's (sorta-kinda), but it suddenly put its nose up and stopped flying and spun in.

@joshuawfinn 3 жыл бұрын

Ouch. Hit it with CA and get back in the air. Also consider gluing an earplug to the nose for some impact absorbtion.

@kenkingsflyingmachines2382 3 жыл бұрын

@@joshuawfinn It wasn't the nose-in, it broke as I threw it. I imagined I was emulating you, but in reality, I'm a lot older, my shoulders don't have a lot of range, and I don't throw things in general with any accuracy. So as I spasmodically jerked my arm forward I overpowered the very light tailboom. I bought a couple of carbon fiber tailbooms when I purchased the kit in some kind of prescient fugue...I have no use or plan for them. Until now. Excellent idea about the earplug.

Hi Joshua, Many years ago I built a chunk glider called zuiback or something close. It was in a magazine. Everything was sharp angles with the airfoil a flat sand in thirds. No rounding. 15” wingspan, 5” center sections with 2.5” tips. Very simple. It was so easy to trim and I actually had a ten minute flute with a thermal over a central Florida ball field. Have you ever run across anything similar?

@joshuawfinn 4 жыл бұрын

Oh yes. Probably my best (and worst) was hand launching a tiny 8" glider and watching it disappear directly overhead 7 odd minutes later. It never drifted throughout the observed flight. Just kept climbing higher and higher straight up. Another time I launched a peanut scale Goon racer into a thermal and it landed less than 100 yds away--almost 16 minutes later!

It's a combination of the right CG, incidence, dihedral, weight distribution, etc. In short, just a really good design.

Plans used to be available however this model is extremely difficult to scratch build because the wing airfoil is very detailed and requires at minimum a high quality hotwire cutting rig, preferably a CNC hotwire.

@joshuawfinn 14 күн бұрын

I should add, there are several models that are suitable for scratch building such as Mikhail Yashinskiy's designs as well as the various flapped F1N designs from Serbia and Poland.
