I coached Daniel Guo, a student at Sierra Vista MS, who won the 2023 Division B Flight event at the 2023 National Science Olympiad Tournament in Wichita, Kansas. The comment posted by RedstonePyroMan about Daniel Guo's model not being optimized is incorrect. Here is why. There were two different strategies that experienced flyers could pursue at the National Tournament. Beckendorff MS, the team that flew 4:05, chose a rear CG, low decalage configuration with a relatively large flight circle. This is why its airplane flew the slowest. This configuration produced a more efficient flight but it was mandatory to fly "no-touch". If this airplane had collided with a beam, it would have lost significant altitude which would not be recovered. This is because at this stage of the flight, the rubber motor would have had insufficient remaining torque to enable the aircraft to climb more than 1 or 2 feet, if at all. Sierra Vista MS, the team I coached that flew 4:11, chose a more forward CG and a tighter circle configuration which could recover from collisions reasonably well and therefore could fly above and between the higher set of brown truss beams. The latter configuration won so it was in fact optimized for this particular flying venue. It bears mentioning that Daniel Guo from Sierra Vista MS won the Division B Flying event flying his No. 2 airplane. His No. 1 airplane landed on a beam during practice and was damaged during the recovery process. Daniel Guo did not fly 5/99 rubber. This is s reference to the May 1999 batch of TAN II rubber which is legendary for its performance with indoor duration stick models like F1D. For the record, Daniel Guo flew his winning flight with a rubber motor made from the July 20, 2022 batch of Tan Super Sport (TSS) rubber.
Go to freeflight.org, find a flying event near you, and travel to it to get advice from experienced fliers. Also go to indoornewsandviews.com -> downloads -> The Best of INAV. Read that document, then read it again and take notes. Find a pennyplane design you like, order materials for it from indoorffsupply.com, and use the "Pennyplane My Way" article as a guide to make a good pennyplane. Then build a second pennyplane using the lessons you learned on the first one in hopes of getting one that's usable. By your third build, still following the instructions, not being creative or changing anything, you should have an airplane that works ok. If it sounds like this is extremely hard and I'm telling you that you can't change anything to make it easier, you're catching on. If you'll grit your teeth and do it the hard way, you'll come out the other side able to build anything, and you might establish a career while you're at it.
In spite of challenging conditions of the air, a real inspiration for the future here. Some brilliant kids here, and my warmest congratulations to the winners. Wouldn't it be nice to have a purpose built indoor aerodrome? With a domed ceiling WITHOUT a tangle of girders perhaps.. Imagine; freestyle category number 4; The Thermal Zone! You could have various colour options for the ceiling. A special sound system. Repair zone. Auditorium seating and so much more.. Is this possible? After all, there don't need to be too many of these things for everyone to enjoy the results, via video and the Internet.. Nice one, Family Finn! 🌟👍
There was talk of a dedicated AMA indoor site but nothing came of it. I hope to build a Cat I facility on site here eventually. It'll be pretty snag-free. ;)
In KS not far from where SciOly nats were held this year, me and my mentor are looking to build an indoor drone testing facility that particularly suits indoor rubber models. We think a ventilation system that introduces air at the floor/ceiling and runs along the walls may serve to keep planes centered better
@@RedstonePyroMan for flying indoor freeflight, my experience continues to be that absolutely still air provides the best flying conditions. It gets annoyingly hot, but the planes like it (also this allows the air to stratify so that the rubber motors get exposed to hot air at the ceiling which extends the flight times).
@@joshuawfinn Certainly still air will give best verisimilitude to the performance, great for competition. If the bird's design is closest to optimal for AUW, span &c, ie winner, this is best reflected in still air. Temperature should be comfortable for humans. You want folks to enjoy it. I vote for an inside dome shape (false ceiling) in a taller building. Aircon under auditorium seats. An experience capable of PAYING for some of the cost. Professional camera/audio.
Oi Joshuawfinn você poderia me indicar um livro bom para construir Aeroplainadores é aeromodelos ! Sou o Marcelo do Brasil e te sigo algum tempo e admiro muito os aeros modelos seus !
No 5/99 was harmed in the production of this Nationals. ;) Both airplanes were carefully tuned and we saw a number of test flights from other teams that went into the 3:50-4:20 range.
End of last year one of their students used a Stinger fuselage and an own design wing. This year several of the top students are using a short kit I made for a larger plane called the Hornet. I don't advertise or list it on the website because it's fragile and hard to build compared to most of what's out there and I don't like dealing with complaints from people who buy a plane that is above their skill level despite multiple warning labels. Those who master the Stinger and come asking for advice on next steps are directed to the Hornet.
@@NandanJayaprakash here is the link. Please heed the warnings--if you're not doing a minimum of 2 minutes with a Stinger, you won't be able to get this airplane to work. It's not a full kit--follow those instructions on the product page very closely. jhaerospace.com/product/hornet-b-2023-4-short-kit-and-plans/
Check out Hobi Cerdas channel, he has some videos on making prop blades from plastic cups. You can also 3D print them if you're willing to invest a lot of time tuning the printer.

Wow that would be amazing to have a plane that flies like that mine don’t

Wow, that is cool. Here we try to put this category on national championship

@@joshuawfinn if it was both warmer and stiller than KS all-state then it makes sense. Still, compared to Wilbur MS (2:43) 4 min is a huge % increase

4:11 is crazy for SciOly, particularly for such a seemingly unoptimized design! You think they were packing 5/99?
No 5/99 was harmed in the production of this Nationals. ;) Both airplanes were carefully tuned and we saw a number of test flights from other teams that went into the 3:50-4:20 range.
Istimewa
How do u make them fly I mean I made so many and they don’t fly can u tell me why it dose not fly😢
Which flight kit the Sierra Vista MS team is using? It doesn't look like J&H kit.

@@joshuawfinn - I will send an email for more details. Thank you!
@@joshuawfinn I would like to get the modified kit. Could you please share the details?

What’s another way to build propellers besides balsa ?

@@joshuawfinn ok,thanks👍

Surely there are better flying sites for a National contest
Unfortunately it's always a crap shoot for what we get. Some years it's great, some years it isn't.
