Do not complain to this guy, if it's not coming back , you all are making a mistake in the folds especially in the adjusting part. Because it came back to me like a charm
For most boomerang paper airplane, it depends on the model you made. For instance, I folded Mr. John Collins' Boomerang 1 and tilted the model to the left or right to make comeback with me. If did not work, I crimped the wing just a little bit.
Mr. Collins....The "Boomerang II" is indeed an intriguing model design that works very well! Have enjoyed perfecting folds and " control surface " tweaking for the challenging / desirable out & back gliding flight profile! Scaled down the 8.5 x 11 paper size by 25% ( Same dimension ratio )....Fold placements same except for final tail wing creases...preliminary experimenting... initial " prototype " works very well too!! Addictive FUN!! How small can it " go "!!? Thank you Mr. Collins for sharing your experiences w / paper aircraft design aerodynamics!!
Worked well with a DIN ISO A4 sheet of printer paper, a wee bit of adjustment on rudder to make it fly straight and it flipped and came right back. Did it in the large steering gear room of the ship I'm on.
Hello Mr. Collins, I'm trying to build the 'Boomerang II' but I just happen to make it circle back, like I use to with 'Boomerang I'. I can't make it stall, flip, and come back upside down. I'm using regular A4 writing paper sheets, does that have any impact on the outcome? Do i need to use any other type of paper? Is there anything I should pay specific attention to in order to get it right? I'm following the instructions to a T but I don't seem to be able to replicate it. I'm 10 years old, I'm from Spain and a big fan of yours. Thank you in advance for your time and reply. 🙂
@@nIkI_nazarov When you actually do the math, it's 25.75. I say 27mm instead of 26 because most people can't cut that straight. One mm won't be the difference between success and failure anyway. Happy folding.
@@ThePaperAirplaneGuy @kolyanazarov8097 It depends, because for an European sheet of paper, the correct ratio (for a 8.5 x 11 inches sheet) for a 21 cm large sheet of paper is around 27.1764 cm. Perhaps kolyanazarov see ratios too; I use this ratio all the time for your wonderful planes(my favourite is the Boomerang I)
1:44 Your comment here bothers me the most. I did the math for this and it does not seem to be 19mm but actually 27mm. Here's my math calculation: American-sized paper: 8.5 inches by 11 inches = 21.59cm by 27.94cm In which if you divide it. 27.94/21.59cm you get the ratio of 1.294 A4 sized piece of paper: ~8.25inch by ~11.75 inch = 20.955cm by 29.845cm And like you said to remove the longest section by 19mm the numbers would now be 20.955cm by 27.945cm and if you divide them you get the ratio of 27.945/20.955=1.33 being nowhere near. the 1.294. But if you multiply 1.294 by 20.955cm you would get around 27.11cm. And then taking away 29.845cm - 27.11cm would equal 2.72cm which should be the longest length that you should cut off. Please correct me if I'm wrong but this is how I understood it to get the correct ratio. If you are using the exact size of A4 paper without the rounding up that I did initially the cut-off for the exact ratio for American size paper would be 25mm longest length that should be cut off which is not too far off from my initial calculation. Lol.
Your math is correct. 19mm is what you would remove from the side of the US letter paper to match A4 proportions, so yes, I misspoke. I don’t think that’s catastrophic for the folding sequence, so I probably won’t replace the video right away.
So, im sure i made the right folds, sharp middle crease and the right adjustments but somehow, it just glides and then tragically crashes upon the ground. I kinda figured it out since it works when i do a fast movement to launch but it doesn't fly farther than a meter before it comes back. Can someone help?
But I know it very well, John's Suzanne is much more powerful than kim' s plane. The only reason they broke the record was that they had the strongest thrower in Korea, while Joe Ayoob was'nt that much powerful. SUZZANE IS THE BEST OF THE BEST!!
So hard to adjust just right, but magical when it comes back I am flying in a cushioned white room saying "positive dihedral, positive dihedral" over and over 🤣
