Pretty cool to see my Hourglass III featured at 7:28 You really need to get a winder and rubber lubricant so you can put more power in the rubber motor. Hand winding like that will only get you 25% of the plane's potential.
Cool. I could build that type of plane with no kit at all. I used to build Balsawood planes back in the late 60s early 70s. Gliders too! Spruce and Balsawood were my best friends when I was a kid! 😁
In my young time, we made this plane use tube from grass. Happy times from Ukrainian childhoods! Cover film made when you putt to the water tiny layer of varnish (capon varnish). After dry we have ultra tiny cover film and use sugar sirup to fix film to frame!
Great video. And I especially thank you for the lesson it wing building. I tried cutting and glueing the plastic sheets together. Its like doing neurosurgery after drinking a gallon of coffee.
Great works. It seems to be very difficult to make. In Korea, competitions are make mainly at schools with rubber-powered planes called “고무동력기”. I can still buy it for 4,000 won (less than $4) and it's very easy to make.
This is very well done! The videography is very good. And you did a great job of building the plane! You must have spent some time balancing and trimming the plane, but you did not show that. Good job! Thanks! :)
7:30 - The plane shown inside right there is a “Microfilm Plane”, which is much harder to build and transport. But still cool video. Cool project! Brought back some memories for me.
Yeah, was going to mention that too. It is the F1D category (as per FAI classification). The microfilm was always very tricky to make and apply (fun with nitro lacquer with addons :) )
i have to wonder about the commenters saying this model is difficult or complex to build, i have built a few Oraldoo Thunder 3/32 scale radio controlled vehicles that are orders of magnatude more complex and difficult to finish
...oh, I want one!...I think I've wanted one of them all my life!...I'm gonna get one, catch a six-pack of Monarch butterfies and then train them to ride it, to keep it flying!...a smashing post...thank you!...
more distance from centre means more distance covered by the props means more air displaced per rotation and less torque from the rubber band which makes it last longer and fly further. But yes your idea would work if you wanted to just make it faster
l'aereo lo costruii moooolti anni fa usando il BALSA , chiodi in FERRO che fermsvano il motore, un elastico e fogli in PVC --- funzionò una sola volta e l'apertura alareera di un m x ala
The curve isn’t for aerodynamics it’s for creating lift because if you had a flat wing it has good aerodynamics, but it creates less lift, then if you used an airfoil like shape.
If I recall correctly, which is happening less and less often, the WWI Spad biplane had flat wings with rather small positive angles of attack. And some of the Russian Farman-type biplanes had curved (front-to-back) single-surface wings. All of the structure was bamboo, and the wings were single slabs of linen. And, just guessing, their power-to-weight ratios may have been comparable to a five gram, rubber band powered plane!
Thank you for showing me never to buy this you can go to any local pharmacy in America and go to the children's fiction and buy one almost built 4. Or 5 Parts total 🎉 PS been making me since I was a child never this hard
😂 I still wonder how u came up with your intro it's quite good but what person goes like whip cream a cat and a sign? I feel like there's a good story there
