FAI F5J - the Introverted, Individual and Intellectual sport of silent heights. Riding invisible air currents from the lowest heights possible, staying in the air for a defined period of time and coming back to land on a designated spot is the goal here. How it is done depends greatly on the weather conditions and pilot skill.
Here I collect final flights from the most of the competitions I attended all around EU.

Very nice👍
I think the grass grew an inch. Sore necks watching them go round and round. Nice flying but i'll pass.
The two competitors that went ultra low for the final flyoff already had zero scoring rounds, so I guess they had nothing to lose and went for final flyoff glory and it was Arijan that made it 👏👏👏👏👏 Interestingly the top five overall was made up with no one winning any of the flyoffs, and the overall winner was not a top scorer (among the top five) in any of the flyoffs. So the consistency of Primož scoring high each flyoff round won him the day 👏👏👏👏👏 Thanks for the coverage and looking forward to 2025 already....
Gradually watching your coverage of this event. Enjoyed your explanation of tactics used 👍 The windy conditions is what I usual experience in the part of the UK I live. Thanks for your coverage - Seniors Flyoff 3 & 4 left to go...
How do they control their planes, with radio controls??
Thanks again for the time and effort filming for us to enjoy 👍 That was great watching the one who had 5 minutes remaining and managed to get the best out of that light thermal to make his/her time 👏👏👏
i don't understand? how do you win?
Thanks first time seeing F5J difficult to video but you did well!
Thanks. I think I figured out new camera and hopefully future videos from competition will be in focus all the time.
As a ex F3J pilot I have to say this is the first time I have seen F5J. I am very confused why the guy downwind that got too low did not just fire up his motor and fly back surly a zero is better than a big Bill for a smashed plane and or worse landing on someones house/car? Are the motors on a single start wont start again timer or something?
Correct. If I remember correctly at world and continental championships motor restart is not allowed. At world cup events contest director can decide to allow it.
Thanks again Jure for the nice event coverage 👌👏👏👏🇦🇺 Nice history info on the location too. 😊
That pick up from Arijan was mighty impressive. Almost no speed but no stall.
Yes, nice to see one in person. That start was recorded at 7m, he had one in preceding competition recorded at 3m.
Thanks for taking the trouble to film and share 👍
Thanks Jure! A pleasure to watch, as I participated in 2003 F3J European championship in Deva, Romania. I'm from Deva by the way..
Thanks Jure! Appreciate your efforts to bring us these events. 👌👏👏👏🇦🇺🍺
Thanks Jure, a really interesting video on the history of F5J. It took me back to my early days of soaring, initially competing in F3B. Around 1975 (still in primary school) after reading some articles by Fred Militky I converted an Airtronics Olympic glider to electric launch. Using a home rewound brushed motor with a homebrew gearbox and propellor it launched and flew quite well. The limiting factor was how long it took to recharge the NiCad battery pack, around and hour. As a schoolboy I could only afford one battery pack build up from AA batteries "liberated" from other devices. We have come a long way but what a ride! Thanks for the trip down memory lane!
Do pilots when in the same thermal have to turn the same way as the highest glider
Not really. But it is considered good manners :)
👍
Thankyou for posting this I thoroughly enjoyed watching this👍
Thank you
Thank you Jure for your enjoyable videos and commentary! 👌👏👏👏🇦🇺🦘
Thank you. Really enjoyed watching this. 😊
Big thanks for video and comentary.
What is the object of this compution ?
From the SWSS website: "F5J is a man-on-man glider competition using up to 4-meter wingspan sailplanes. The planes are launched using an onboard electric motor and folding prop to a pilot-determined minimal height to achieve the 10 minute target flight time. The competition consists of 4 or more qualifying rounds of 10 minutes, with optional fly-offs for the top 30% pilots featuring 15-minute rounds. Flight duration must be within the working time limit of 10 minutes. Launch height penalties are calculated based on maximum altitude reached by 10 seconds after the launch motor has stopped. Landing bonus points (maximum of 50) are awarded based on proximity to a marked spot, but are lost if overflying the working time limit. Scoring includes flight duration points (1 point per second), landing bonus, and subtraction of points for the launch height penalty, with the top pilot's score normalized to 1000 within a flight group. Motor run time has no penalty, but a maximum limit of 30 seconds applies."
You are getting good with comments ;-) Now try to use manual focus and you will not loose the focus as often.
It's a question of how much I look around and how much through camera. I'm switching focus between auto and manual regularly but that is not good enough, as you can see. I plan to upgrade my main camera still in this year so fingers crossed my footage next year will be sharper.
@@jurepecar9092 jojoenno means that from your second vantage point (from second flight to last) all planes and rc pilots was enough far away so you could set camera manual focus to infinity and hold this for entire race. No need for auto focus
Your videos are crap so why should he listen to you
@@igorprofusek4573 Unfortunately not true. Retail lenses require re-focus on zoom change. But indeed, manual focus is a good start for long steady shots.
Everyone is happy and well done to everyone!!! All 5+. Operator 3.
Thank you.
Nice to follow you around in Europe. How much do you think it blowed and what weight do you think they had?
Thank you!
Thanks for your efforts to bring us regular competition footage. Much appreciated from the UK.
Thank you for posting this. I really enjoyed this video. Those pilots are so good!

Thanks for bringing us the footage. Looked challenging and stressful low down. The difficulty in filming reminds me how amazing the human eye is.
I could not have put it better myself
you make great job 👍 thank you🎖
Thanks Jure - I always hunt to see if you have a new video for us! Especially during Southern hemisphere winter. Please keep it up!
Thank you Jure for your nice video!
Welcome back, Jure. I really enjoy your videos, and enjoy and learn from your commentary. Please keep up the good work.
Great overview of the history of model gliders, loved the speculation about future directions . Also congratulations on being a Aptera promoter. I too am an early reservation holder and Accelerator investor, and a company brand Ambassador. Aptera looks like it wouldn’t work at first casual glance,,,,, but,, once one takes a DEEP dive into company and design and novel manufacturing ideas it begins to dawn on you, that not only will their ideas work, but if they make it to large scale production and adoption Will COMPLETELY revolutionize personal transportation since the first horseless carriages. Hopefully starting a trend that others will follow. I know it sounds TOO good to be true, but i guarantee you, this is one of those black Swan moments that could literally change the course of history, much like small inexpensive brushless motors, and tiny powerful Affordable lithium batteries plus super light but strong molded composites did for modern electric Model gliders did for our sport. IMHO Aptera represents nothing short of the NEXT sensible logical step on the evolutionary path towards a TRUELY sustainable and more importantly AFFORDABLE transportation future ( yes, it’s that BIG). I’ve been to Aptera’s HQ 2x and ridden in two different protypes and followed everything about them, met and spoke with the founders as well as many of engineers and employees there. Jure , when I’m there next I’ll share videos and info about their upcoming production intent builds with you and your viewers.

Thanks for making this video and posting it. I really enjoy watching RC glider thermal videos like this.
It was great to see the references to Frank Zaic in your video. When I was in US high school, we had an aviation club. The club had a year long competition, and the winner won a lunch with Frank Zaic (1978). Turned out that he lived only a few miles from where I went to school. Sadly, I was too young to recognize this rather high honor. Interestingly, I met up with him and his wife about a decade later, when the NAA presented him with a lifetime achievement award. I was at the NAA meeting to receive an award as well due to my setting the F3B #25 world record (declared distance to a goal, which was an rc glider flight of 266 km point to point). What was great was that by happenstance, Frank and I ended up sitting next to each other in the audience. By that time, I recognized my amazing luck to have met him, and more than once. I have been so fortunate, in so many ways.
Hope all is well Jure! Spring time has tricky strong thermals. You have to optimize all climbs to survive the bad air. I love watching others fly because you can always learn things to apply to your own flights. Cheers from the USA!
A big problem in popularising the sport is that almost all, if not all, F5J competition models are composite and generally professionally "factory" built, and therefore expensive. Some people make their own, but that requires a good airy workshop which to modern apartment dwellers is inaccessible. I suggest that you look at the development of the F3-RES (FAI F3L) class of two-metre glider launched using a rubber hi-start ("bungee"). The F3L rules specify largely built-up wooden wings, tail surfaces and forward fuselages (the boom and spars can be composite and are inexpensive and widely available). This makes for a much less expensive model. There is also an RE built-up glider class in Czechia, of less restricted size, oriented toward beginners and youth. I wonder whether something similar may be a good idea for electric powered gliders. The built-up designs of Mark Drela are a good beginning point; the F3L gliders are similar to his 2-metre Allegro Lite, and his 3-metre Bubble Dancer glider is in the F3J class, easily adapted to F5J. While Drela's very strong high performance winch-launched gliders date from circa 2000, his aerodynamic ideas and airfoils have been dominant in model glider design since then, with manufacturers building lighter and more slippery models over the years. Incidentally, the F3J glider class was established after the 1981 F3B World Championships in California, when composite designs were taking over and the Canadians terrified everybody with Kevlar models launched with 36-volt winches (I flew wih them when they were training in Victoria, BC). Not only was the F3B rulebook rewritten, but F3J was set up as a more sedate thermal duration class, launched by human towline power instead of ferocious winches. Somehow that quickly translated to an even more powerful launch than winches, and the composites took over, displacing the gentle floaters of the 1970's that no doubt everybody was thinking of when setting up F3J. The F3L class avoids the expense spiral that all the other classes have suffered, though balsa kits are not exactly cheap these days.
My dad nearly made the US World Team in 1980/1981. He started by flying the long thin winged gliders of the 1960s and then build a Sailaire (sp). he found the tail would catch on the grass. He built a tail cone to protect the rudder. He liked to "kite" the sailaire when launching from a winch or hi-start so he developed a toe hook that could hold the line and then release it. At the NATS they gave him an award for best technological innovation (it was also the year my mom was pregnant with my brother - much joking happened around that). He was on a first name basis with Dan Pruss, who was instrumental in the US with the NATS and The Great Race. He and Dan as well as a few other guy rode in Dan's van to contests around the midwest. Stories were made that our now legends. When I came along in 1973, i was named after Dan Pruss. I can remember going to the flying field and seeing guys gather around a plane, listing to the flyer talk about this improvement and that - or stand around a wreckage discussing what led to the crash. My dad saw the limitations of the Sailaire - it was slow and couldn't penetrate the air to search for lift. I can't imagine how it would fly on a windy day - add more ballast? He found the Viking II to be the future - his answer to the TD 10 minute Task. He built two or three sets of wings for it - a flat bottom for light days and a semi-symmetrical for windier days (I probably have that wrong). He built in a release-able toe hook - then mass produced. With the Viking II flying stab elevator design it was like the Sailiare - it could make a tight circle for thermalling and maneuvering. He added a automotive engine belt to the nose to grip the ground for quick stop landings. He practicing his 10-minute flights and had me countdown the watch as he made timed circles near the landing area. All of this was in preparation for the US Team. He finished just outside of the team. Family took more time and he spent less time in the hobby until we all moved out of the house as adults. Once the hobby was one of building and testing your build. It was one of personal innovation. The highs were heroic and the lows meant it was back to the basement shop to fix, rebuild or build anew. On powered plane fields - the smell of hobby gas fuel came from trash cans which collected the crashed parts of broken dreams - to return to the field or never to return again. My dad's Viking II disintegrated on a demo speed pass. I remember seeing the plane come apart and spiral into the ground. He found it was a bad glue joint on the spar (I think). He went home and fixed the issue - never to happen again. He added a composite spar - a sandwich of carbonfiber and foam to later spar designs. These days - he flies an Ava Pro - beat up like a NASCAR car after 200 laps - but he wings contests with it. (I finished last year in 2nd or 3rd place with it www.mvsaclub.com). He flew a composite plane programmed by Chris Lee ( a young, now retired from R/C Soaring) engineer minding man who helped bring the club into the current era. We have contests and enjoy flying but the barrier to entry is pretty high as well as the learning curve and risk to learn, crash and try to fix a modern glider. Instead of talking about design and build they (I try not to) talk about a dominant design as if it were the new name for "glider". We fly beat up and repaired carbon fiber gliders - old by today's standards - against $4000 pre-made gliders from the best aerospace designers around the world. We do live in a new time but what can we do to bring back the scrappy world of "let me fly your plane - you have a warp - you need more wash in or wash out - come over to my house and I'll help you fix it with my heat gun - and then we'll fly in the contest next week" world? I don't know? We also don't fly in public parks - we fly on private fields - people don't accidentally stop by and want to learn more - nor do we reach out to them. (Sipping my working coffee - typing out this "article" on TH-cam - bemoning a past I had issues with but now seeing it was a golden era - get off my lawn - I'm getting older.) Now I'm our club's webmaster - and this question is on my heart - when I care - and not on my heart when I give up and fly my beautiful Xplorer 3 - repaired with epoxy by my dad. (I need to pain over the scars) My dad's basement is filled with balsa gliders containing address labels of his friend who passed away - a museum.
Thanks!
Enjoyed your discussion 👍 and thanks for the videos you record and upload each year - I know it's a lot of effort. Developments in electric power for RC gliders combined with composite construction methods has opened up thermal flying for so many of us. Even though I don't (or can't) compete I'm someone who very much gets pleasure from soaring like the birds. The Aptera looks very interesting...
Danke, very good job👍
Thank you 👍
W❤W! That’s Incredibly Awesome! 🤗❤️✨
Are gliders with batteries, motors and props still gliders?..
What is the module name of height sensor that shows how high glider was?
There is Altis from Aerobtec and Multi from RC Electronics. Probably there are others too. FAI CIAM has a working group certifying all allowed devices, they should have a document online describing them.
