Let me know what you think of the videography and editing by Chris Edghill, I think I found my new secret weapon!
Thank you Curtis for helping every step of the way. Would not have gotten this off the ground that morning without him.

I'm glad you got over the incident and any self destructive thoughts that came with it. Go. Go bigger. Go stronger and push the limits of what is perceived as possible.
Despite the crash, this project/video is one of the greatest W’s in recent RC-Maker-RUclipsr history. Raising the bar once again
😂
They should throw a small gas RC engine on it
It really isn’t lmao
Thanks for the spoilers. Lol
Spoiler alert now i wont watch ot ffa
For me personally. You are the most entertaining content on the tubes. Mid 80s, I was free flighting when it was still, and Windsurfing when it wasn't. Freeflighting is definitely a polymath's sport. All you do is run and think. (1988 Australian hand launch glider champion. 6 one minute max's, second throw was 27 minutes)
Love your work

Servos were soo expensive even in the late 90's. So many people have access to inexpensive flight now. It's awesome as a hobbyist
Aww man! The whole time I was watching I just knew it was going to fly beautifully then the tragedy 😫. Great project, so glad you are going to continue.
“The joy of success is greater…” good advice, I like it. We’re looking forward to Part 2
This man refuses to give up and is dedicated to making the most masterfully crafted models. That's why think flight is so different from so many other youtubers
This Video deserves a lot more views than it has! Every adult that ever bought a Barn Stormer when they were a child should watch this. I watched the first video of the build months ago and I am impressed.
Great project and collaboration. Can’t wait for part 2 from a hill.
Gotta say your cinematography is top notch.. i can't wait for part 2!
Thank Chris!
Same here
You are 100% worthy of a RUclips channel. This was a great video, showing the progress through failure is about the healthiest thing you can share and will make your eventual success well worth it for all of us.I cannot wait to see the next video. Thank you again for great content
You probably can't see it from your side, but this was epic. It might have been a failure, but we come here to see the moon shot, win or lose. From a channel perspective you win either way by attempting what most of us could only dream of.
Definitely epic! Success is not a destination, it's a journey. Something is only a failure if we don't learn and improve. Failures are just waypoints of pause on the way to success.
Countless early aviation pioneers may well have experienced this phenomenon in full scale and not lived to be able to even ponder what went wrong. You have very admirably demonstrated the importance of simple torsional rigidity in an aircraft wing, albeit unintentionally. If I were teaching aerodynamic fundamentals I would make a clip of this video mandatory viewing. Whilst you may not have achieved that which you set out to, I think you have recorded something of equal or better value. Sincere congratulations.
Chris is the man, wish more business owners supported local creators, i know they got businesses to run but some are just awesome. Thanks Chris
The balloons! We wanted to see them pop! So fortunate that your video captured exactly what the failure mode was; it's so much easier going forward when you can see where you're going. Love the channel!
As a man child and a FPV hobbyist , HELL YEAH! Rubber band powered balsa- planes is what usually gets us wanting to fly bigger. Alot of math going on there. Watching from the sticks Of Tennessee. If your not Crashing,,Your not doing it Right!❤
I'm so glad youre not giving up on this project because this is super cool and it's going to be epic when you get it to work. "The only differnce between failure and a lesson learned is your mindset"
Awesome stuff, glad you are not giving up! Reminds me of loosing free flight models in trees as a kid
in my mind it's never the outcome of an project like this that makes it "worthy", but the fact that you attempted it. great video. keep them up. no matter which way they end up going.
I think failure is easier to stomach when you can see a way forward, and you've clearly got that vision. I look forward to more!
Fun project, even if the ending wasn't what you were looking for! If you do more balloon projects in the future, please lay the tank in use on the ground, or strap it to a stand. An unrestrained tank falling over without the safety cap can shear off the valve and take off like a deadly rocket.
I love your determination. In the propeller’s blade twist, I recommend the propeller’s root angle not exceed 75 degrees away from the blade’s direction of rotation. Your current design clearly reaches a full perpendicular 90-degree divergence from the blade path, which creates extreme drag and reduces the thrust output.
I got sick to my stomach watching that beautiful plane lawn dart like that, but you were absolutely right, it was a huge oversight to not try to account for the change in forces exerted on the airframe. Build back better, I’m excited to see this thing fly!
I’ve been so looking forward to this!
You build it twice, you build it good.
That's the SV Seeker motto - very suitable for this situation.
I expected a crash (normal in model planes) - hurts, but the joy of flying after repair is worth it. Best of luck!
We all learned something at 12:36. Nothing wasted. Well done.
As a kid, my Grandad and myself had huge fun with elastic band powered planes. Your work really brought back those feelings! Also, the guy who donated the gas! What a cool Dude. Carry on Sir, you rule. 👊👊👊
Such a simple concept, yet the journey proves it's anything but. Perfecting simple, upscaled models is a noble cause. It's not the why, but why not. This is a very interesting series, and really enjoy the editing, video shots, and music on top of what you are doing. I hope to see your success in this journey!
How is that a failure - the video turned out great and now you get to make another one!
Well done for all the effort. When one bravely ventures into the unknown, there are surprises. There is a saying in my country, “only riders fall from horses, he who walks on his knees does not fall”.
Fantastic!! Back to the lab with new ideas on wing structure!!
This looks like an idea I would've had when I was 9, and I'm 100% here for it, let's GOOOOOOOO
Do no loose sight of your goal, and thrust the process. The journey is where you learn the most.
Love your work and your channel! Thank you!
Keep on going! The repairs never take as long as you think, especially with an open structure like this.
Diagonal bracing between the ribs for torsional rigidity, but also check the angle of incidence... tricky to tell form the video but it looks as if the main wing hasn't got much of an angle of attack relative to the tailplane. With more decalage, the model wouldn't have sped up as much upon release. I'd also add a couple more degrees dihedral too.... great work, very much looking forward to the next instalment!
YES! I wanted to see more of this project...sorry for how it ended but learning happened and better for it -keep on! One thing may help, aside from improved wing torsional rigidity; slightly more down thrust and a bit more decalage. You'll probably need to adjust the c.g. fwd. The initial powered flight in this video showed it nose up a bit. Probably could have a longer powered flight from hand launch. In any case, superb build and engineering. Yeah, ok enough armchair engineering from me. Thanks for continuing- looking forward to more!
I guess you know now that you start with zero airspeed which causes a dive that’s hard to come out of without elevator control. Looking forward to the next ep
That's a nice airplane.The giant version of my first flying models as a 6 year old I loved the Gillows ones that come in skinny bags.I had every version of them including a bi-plane.aThey were great fun.
I think we were all yelling at our screens collectively "Noooooooooo!"
It weathered the crash pretty well though. Looking forward to V.2!
That was epic! Can’t wait for round 2!
Definitely made the right choice in putting this up
Laugh it off if you can but know, we your viewers love everything you’re doing so good on you!
Thank you 😊
This build is so beautiful. It will fly gloriously as long as you keep at it.
A sequel!!!
Loving the music and the quality of the filming. It feels very dramatic and professional.
I wanted to see the balloons pop! Beautiful model, looking forward to the Phoenix edition.
Ugh! I know that feeling of failure... but we all fail. Don't give up and keep sharing what you learned!
The success is that we are never disappointed.
Your story telling and film making are a pleasure to follow.
Thank you
Am so impressed with the engineering of this design that keeps this aircraft light, strong and being fully transportable in a normal vehicle (9:17). Such an impressive set of engineering logistics and constraints to balance and manage, while staying true to scale of the original balsa model.
🤯♥
The flight sequence from 11:40 was not expected! Left me wondering if could have pre-revved propeller rpm, so as to release with positive thrust? Questioning if the aircraft was able to create positive thrust relative to airflow profile as it flew. At higher speed the blades of a fix pitch prop, can act as airbrakes. Thinking negative thrust may have been a contributing factor to the downward pitching moment.
While the outcome may not have been desirable, this chapter of the project did collect lots of great data. Making connections with Chris, Curtis and others helping behind the scenes was definitely a positive outcome for this chapter. Thanks for sharing your rollercoaster of engineering and learning endevors. Look forward to the next chapter. :)
I'm glad so happy you are continuing, I wanna see that thing soar!
Keep it up! Amazing series. Your production quality and story telling, outside of the amazing engineering, is amazing.
Everyone for us got so cool experience with you. Thanks!
I think you should use a shorter rubber band. Your issue seems the power and not the period for which it's produced, so a shorter band will help with that. In addition, it'll drastically reduce the weight. I could be wrong with this theory, but seems logical to me.
So wild to see Lucerne Dry Lake green! I'm sorry about the failure, but this is all learning. You're doing great work.
Not a failed attempt at all. KEEP GOING! You got this!
Wow, what a fantastic project! Seeing that plane fly under it's own power is amazing.
Seeing her flip over after being released from the balloons is heartbreaking.
Looking forward to your next projects and the continuation of this one. I wish you all the best with this and your other projects and good luck.
Failure is a part of the learning process and essential for improvement. KEEP GOING!!!
Looking forward to version 2! Never give up such an amazing project.
love this project. so pure.
Some advice:
1) Materials like Monokote and Ultracote are specifically made for model airplane wings and they resist twist and stretch far better.
2) Your propeller pitch is too high given the size and the torque the rubber bundle can put out. This is why the model won't climb very well as the prop is not generating much thrust. It is like starting a car at a high gear. The shape of the prop is really made for the small 4-5 inch diameter props where the rubber torque is very high for the size. The pitch is intentionally set very high so that the prop won't spin crazy fast and waste power. For your large model, since the rubber torque is relatively much lower, you need a much lower prop pitch to provide enough rpm, good thrust, and duration. Note also when all is set right, the model can climb unexpectedly high and it could ride thermals (especially under calm sunny weather and the temperature is rising). Unless you have a way to let it come down controlled manner you could lose it. Please be aware. 👍
This isn't over yet? "To be continued"? GOOD, I look forward to seeing what improvements are put into the next version of this beast.
You can use a pendulum for the elevator and a clockwork timer for the rudder and dethermalizer. I used to do that in 70s and you can still find that stuff today if you look up free flight thermal flying. They even have international competitions.
Wow these projects keep getting higher stakes. Cavin is a serious professional by this point.
That hand launch was glorious though!
Chris is a legend, huge respect to him.
Glad you were able to so precisely identify the problem, personally I thought it was a CG issue!
Also curious about your thoughts regarding a tow launch? This looks to have a wing loading low enough that you could actually run with it
Great video and so sad it crashed. Having flown RC for years I can understand how it feels when you have a crash like this. Look forward to the repaired, stronger version. I also liked your system for exploding the balloons after your release, instead of them just floating off somewhere.
I have nothing invested in this project other than about an hour that I've watched the videos .... but I cried anyway . . . . .
I am sorry for your loss, but at least you learned some valuable information for the next iteration.!
Damn that sucks! I agreed when you made the decision not to add elevator control, but then, yeah too bad, can't wait for the next video!
Thanks for sharing your failures, too! And big thanks to Cal Tool for the donated helium! Keep on rising to the challenge 💪
Ooooh noooo - what a crash! But still, great video, awesome project - whatever the (temporary) ending. But, lessons learned and passion sowed - what more can one ask for?
Glad you're taking this in stride, because you know that the Wright Bros. didn't succeed every time. Can't wait for the next video.
Thank you for showing your failures along with your successes. It really encourages a maker like me to keep trying when I walk home with t-shirt full of foam bits
WOW! That's fantastic!
I've really enjoyed your journey tot his point, too. Thank you for sharing.
Too bad about the plane, but everyone learns.
awesome project
Here's an idea, put some helium into the main frame of the plane to reduce weight.
Even if it is reducing the weight by just a little bit it's going to help to stay longer in the air 😉
Keep it going and thanks for the share ✌️
Even though it did not do want you wanted, that was an epic short flight.
It's still a magnificent build and I enjoyed this from conception to crash!
I truly admire your building skills, production quality, tenacity, and perseverance! Simply Great! Can't wait for the next video!
Oh man that elevator servo is a MUST! Way to persevere! I fly an old Zagi, flying wing and love anything RC! Great content!
Thank you for the reminder to keep on building.. you got this boss
This was incredible despite an undesired outcome. Now you know where to improve so that next flight will be even greater! You've got this!
This channel is such an inspiration
This project is amazing, please continue! Your perseverance and attitude towards failures are very inspiring! Thanks! Greatings from Ukraine!
Persistence always pays off.
Love your channel 👍.
That bitter taste in your mouth when you witness a project fail like this makes the sweet taste of success so much more nourishing. God speed sir!
Excellent cinematography and kudos to your will power. This channel is a 💎.
I feel so sorry that the plane crashed. It was nicely designed and initial flights were encouraging. Thanks for your effort and good wishes for your next flight(s).
Do it again!!!!! But go way higher first. It would've flipped back over eventually. Also, fix your problems. Don't give up.
Such a calming channel. It’s such a nice change compared to all the pitcher shouting channels.
Yes, so true… The moments of flight are soothing to watch…
Totally awesome project! Don’t stop. Love every moment!
This may not have been the result you wanted, but I think it's still a very valuable video. Even with a lot of planning and a lot of testing it can still go wrong and you may not end up getting the amazing result you wanted. You could've not posted this video. You could've worked on a new version and release a video with this mistake as a side note. But instead tou decided to share the raw reality of what happened. We're bombarded with videos of amazingly talented people who create amazing things, but this makes our own failures seem like we absolutely suck at it. Reality can be really demotivating because of this. Seeing someone like you fail and seeing your reaction to it is simply inspiring to me, and I'm sure it's inspiring to others as well. Sure, we can gice up after we've failed. Who knows if it's going to work next time. But we can at least try!
Thank you very much for sharing this experience ❤
Thank you for sharing this comment.
That was awesome of Chris,
Chris kudos to you brother what a nice thing to do. It may have been a small thing to donate the helium but we definitely need more people like Chris in the world, not because of or for free stuff, but just because being around positive people like that help further the projects in a way money can't help, it makes the possibility endless all because of a positive outlook on the project and it makes it more like you want to go further, faster and better because your not just doing the project for yourself anymore but the other people around you who want to see the project a success. I apologize for rambling on but it was difficult to type this and get my point across while in 3 different conversations hahaha long story short nothing but respect for Chris and the team behind this plane weather support being monetary, physical help, or just emotional support to keep on pushing! Much love and respect brother!
I just finished the video, I'm really sorry that it crashed. I are definitely worthy of a RUclips channel your doing things that as kids we all dreamed to do but your daring to do it! I know with setbacks come a little bit of darkness (hence the "I'm quitting RUclips" out of frustration) but you got this and when you do Its going to be epic and no doubt in my mind you will crush this and we will all be here in the good times and the bad times. This is gonna be absolutely epic what comes next with what was learned this flight
Gooooo!!! Your channel is so amazing and your projects just stunning. The fact that after such a blow you decided to try again made me cry. You both rock!
Damn!!! I am so glad that you did upload your succes!!! Every fail is a big step closer to the goal. Making things by failing goes faster than making things without even testing. Go go go! You can do it!!!
Mount the wing a tad higher, further above the CG for stability. Or maybe add some deheidral for the same effect. No reason not to have both rudder and elevator. And to combat wing twist, you could try some internal cable bracing between the wing formers. Or go for diagonal, x-formers...
Lol. Nice show. You got crazy ideas and you make them come alive. 👍
Great job. Being part of the experience through your video is what it's all about on RUclips.
Next time the refinements should be interesting, and I don't doubt at all you'll be sharing with us great videos.
It's a wasted day if you don't learn something new 😁👍❤️
3:51 This reminds me very much of gliders I see at the RC flying field. They will stay up in the air for hours if you can catch thermals but they just shoot up into the sky like I rock it initially. It is so fun to watch them as it is next to the dog park and I constantly see them flying overhead of me even though it is not part of the field.
Dont give up, try it again please...Brought back memories of the Northern Pacific Star Flyer!
Your channel reminds me of my favorite saying: *Curiosity killed the Cat, but Satisfaction brought it back!*
Looking forward to the next chapter.
"Let's fix it!" - yeah!!!! That's the way how to do it! And I'm sure you will be successful. Many greetings and good luck from Germany.
Next time you should attach a fishing line to the balloons. That way you can reel them back in for a second flight.
This video ought be interesting....
I took the Guillows Flying Machine or the baby, baby, baby brother of your plane and added two micro servos with receiver & a tiny brushed motor to it after adding a movable rudder and elevator by using scraps of balsa that was in the box of die cut parts for the rudder & cutting off 5/8 inches of the horizontal stabilizer to form an elevator. The hinges were made from two parallel strips of painter's tape joined at the center with a coat of CA after aligned.
It flys beautifully in a calm sky. Love it.... Nothing else I have performs like it and its charateristics are very similar to the old Ugly or Slow Stick that Eflite seems to have brought back.
