Rubber-Powered Model Airplane - 31" Span 1914 Martinsyde S.1 - Trim Session #4

[@kenkingsflyingmachines2382]

One thing that strikes me is your ability to fly and video simultaneously. The whoops of boy-like joy seem to be the result of careful planning and meticulous attention to detail (like your models). The amount of support equipment you bring out to the field must be impressively complete and organized. I don't think there is anything as dramatic as a rubber powered biplane in the air...I love the sound of the power burst. Beautiful plane, beautiful flying. Thank you.

[@maxfliart]

Thx, Ken. Setting up various cams has become more routine, so it doesn't distract as much as it had early on. It's a carnival show sometimes... But most important to me is that I use the good air & conditions as efficiently as possible, since they're a rarity. I never know what I have until I see it later, but I'm always pleased to know that I've recorded the entire process...good or bad.

[@winnipegperfectcircleflyin7859]

Well said.

[@gregmwheeler]

Love, love, love the shots of the landed plane in the landscape. Beautiful.

[@wojciechkoska3515]

Engine sound in the background, coincidentally wonderful effect. Superb👍

Max you are just jolted 62 years of wonderful memories from gliders to rubber free flights escapements single Channel 2 channel 3 Channel 4 channel actually build tissue paper then silk sneak into the field the middle of the winter drinking hot cocoa sitting in the car to warm up talkin about our last flight patience my dad used to say was the key to a beautiful flying plane I can see that in you sir

[@maxfliart]

Thx, George. I'm glad the film triggered a good memory for you.

[@philipbrailey]

Beautiful model.

[@K3Flyguy]

29 minutes of my life well spent watching the evolution of a flight, thank you!

[@maxfliart]

Thx, Michael. This was longer than most, but there's nothing quick about trimming. She now feels much closer to being in trim.

[@davidmiller4594]

It's the meaning of life ✨️

[@boxersepp]

I came across this yesterday and felt compelled to revisit today. I built balsa gliders in the 70s and thought I knew a bit about model planes, but I had no idea there were such powerful rubber motor planes. I get a good vibe from watching this, almost quasi-meditative. I also find the video well shot and edited. Thank you for sharing your experiments and your excitement.

[@polygonalmasonary]

Your models are so perfectly built, they remind me of my late Father (RIP). My dad was a perfectionist, he built some astounding model planes and passed the love for this hobby onto myself. I've never been as precise as he used to be but I've had many happy hours building planes :-).

[@maxfliart]

Thx for the feedback, Paul. Our dads' generation has been an inspiration.

[@Gutodaflauta]

Bro, thanks the Nice post. I've built dozen models. Actually a pleasure. T.F.H. from Brazil.

[@vinniemon-i5h]

It looked so scale just floating there in the sky glad I came across your video ❤

[@manfredruhmer6355]

Congratulation to this nice plane flying perfectly! No need of electronics, engines and batteries. Thank you to show that!

[@citicolina]

Beautiful. So rewarding when they finally fly like that last flight.

[@roachcatcher266]

Well done sir, a true master class in trimming a model aircraft.

[@dereka6762]

Many thanks for posting this - it's been over 40 years since I gave up the hobby and I'd forgotten how beautiful silent free flight can be. Best wishes.

[@jjs3287]

I have been making models for nearly 50 years, I fly RC fixed wing and Helis and am subscribed to many RC flying youtube channels but yours, sir, is a real treasure because it captures the very essence of the beauty and tranquility of flying.

[@maxfliart]

Thx for the kind words. I show what I feel when I fly, a love that was passed down to me by my dad. I'm glad that you're enjoying it.

[@tedmoss]

I have been making models for over 70 years now. My father started me in 1948 when I was 5 1/2 years old with large rubber powered and 1/2 A and U-control, and I still enjoy building and flying electric R/C.

[@musicbro8225]

Just Magic! The day was so kind and the field so soft. I think gliders/low powered planes have a deal with the wind and atmosphere more than with their owner :) That sky though towards evening was very dramatic and you captured it perfectly; Bravo!

[@matthewmattholew7905]

Very nice. Beautiful, Graceful, and Educational all at the same time. Thanks for sharing.

[@jmmvangoor]

I pay 1000 dollar for this beautiful model, thank you sir for this video

Ok...I just started this presentation and the screen shot of the uncovered airframe BLEW ME AWAY!!!

[@tomasharris3883]

loved your vid. watched the build vid also. brought me back to my boyhood in the 50,s. beautiful build by the way, a true master of the art. many thanx.

[@motoflyte]

You must have a large collection of beautiful planes...

[@keithkennedy-tyson8578]

You bring back childhood memories of flying similar planes with my Dad. Thanks from Tasmania.

[@MarkCroucherRC4fun]

Fabulous to watch a man at his art thanks for sharing.

[@freetimetv5991]

In every video, the models are very cool. I think this is one of the best model airplane channels.

[@maxfliart]

Thx. Glad u enjoy it.

[@mrsmith4662]

What a labour of love. A lovely model.

[@jeffrenman4146]

hello I found your video and I thought it might not be interesting I was wrong… You are a fantastic content creator and this video where to start… It's like so beautiful and I could feel your love of flight throughout. It was like going back to the roots the beginning of flying machines. When you hand launched in slow motion it was so beautiful. My friend I am at a lack of words your video left me quite moved. I could feel the air I could feel the flight it was simply amazing. By the way I'm a chopper pilot and I never thought the elastic power would be something I would be interested in but your presentation left me breathless. This video was absolutely beautiful… good work beautiful airplane beautiful location your narration everything… Thank you for sharing this moment I'll never forget

[@maxfliart]

Thx for ur kind words, Jeff. I'm glad u found and enjoy the channel.

[@836dmar]

Tom, All your videos have always been lovely with excellent production value but I do love the way you are talking through the trimming process. Beautiful and educational. Thank you!

[@carlosballesteros4670]

What beautiful airplane. Success isn't mine but I have a very nice feeling of happiness because at the end, all attempts and corrections paid off with a final superb flight. Send you my best from Mexico.

[@73F100]

I actually fly RC but very much enjoyed this video. Great job of building and flying! Amazed at how you are able to fine tune the aircraft. Thank you!

[@mr.kilroy6818]

That's beautiful craftsmanship !... The flight was fantastic' cudos !

[@norman74n]

I’ve always thought that beautiful rubber powered models were never great flyers. This beauty proved that wrong. What a beautiful realistic flight.

[@maxfliart]

Thx for the kind words. It's a pleasure to fly these birds.

[@chrisgosling5408]

Quite the tonic this one, quite literally a great way to unwind!

[@frankflstf]

Really cool how you can fine tune that plane ✈️ what a great job you did

[@Yogenh]

It looks great and flies well

[@charlesfoster141]

Yes, beautiful airplane model and marvelous flights. I think more power would serve it better. Thanks for sharing.

[@thomasdobbs9001]

THAT BRINGS memories of my younger years, I am 75now, still FLYING , free flight, get younger TO chase it down, have had 11 ops and not found, super triming flights! Keep it up, not enough bf's left. Good day!!

[@maxfliart]

Thx, Thomas. Glad u enjoy the films.

[@ldcrumley]

A life well spent. Thank you for sharing a small part of it.

[@Fantastiko13]

Absolutely gorgeous model, and very beautiful work. I am primarily an rc modeler however have heaps of love and respect for all different types of aeromodelling. It seems Free Flight and Control Line are more a rarity and considered vintage if not disappearing forms of the hobby nowadays which increases my intrigue. More of a reason to continue sharing the wonders of model aviation with others. This video is a lovely treat. Enjoy!

[@tomcoryell]

Isn’t it so satisfying when you get a plane trimmed well and get excellent flight duration? Your planes are amazing and beautiful!

[@MetHerInBaghdad]

I love the happiness you can hear in your voice as you get close to where you want it. Extremely satisfying!

That's an amazing day I've only built a couple of peanut scale but loved the build and thr little bit of flying.that I've dome Loved the video !!

[@19sloper]

Beautiful. Can't think of a better way to say it.

[@tim7402]

Hello from northern Thailand, really enjoyed your video. I'm an electric guy, expat Canadian retired here. Flying and building foamies but the real challenge is the heat. That field you flew at made me homesick for eastern Canada where in summer it's easy to find a soft hay field big like yours. Not the case here, every inch grows rice or something. And even after the crop is done fields are hard stubble, so I missed your dandylion, plush grass. Kudos on your patience trying little changes along the testing. I never was exposed to your aspect of the hobby and now see it's details, details that count. Nice music and that slow Mo of you launching was "Budddddaaahhhh" . All the best. Tim - Chiangrai.

[@maxfliart]

Thx for the kind words, Tim, and for reaching out. I enjoyed hearing ur perspectives. Cheers.

[@MatsAndersson]

What a beauty. Good job.

[@GuzziIan]

Thanks for sharing your trimming techniques. A beautiful model and a true joy to watch.

[@sailr]

You rubber guys have incredible patience! I have thought about building some rubber but since I fly R/C I don't think I could tolerate all the tweaking and finicky results! Fully enjoyed your video!

[@fishercawkey]

This video is a great introduction to the importance of persistence and SMALL changes in trimming. And 18:10 may have been a "fluke" but there's nothing like the feeling of catching a thermal with a free-flight aircraft. Thanks for sharing!

[@Jester123ish]

The most realistic rubber band scale model flight I've ever seen!

[@NemoVir]

It’s beautiful as a static model, it is wonderful that you can make fly with grace.

[@mitchilito99]

One of the best uses of a half hour of my life I could imagine. Thank you for that!

Beautiful model, I would be too worried about loosing her. Brilliant how she lands on her own. Great to watch 👍🏻

[@sailawaybob]

That is a Beautiful bi plane I'm so intrigued by these balsa planes powered by a rubber band. Yeah we had them as kids but nothing like this.

[@SomeGuyInSandy]

Beautiful model, and your tuning is spot on! Very cool!

[@murraykriner9425]

Great looking build you have there. It's all these little nuances that have bearing on its attitude and tailored trim you've lent its flight envelope. All trial and error to one ends, to get it to track cleanly while maintaining its stability. Great job!

[@maxfliart]

Thx Murray. I definitely take a slow, methodical approach. Patience seems to payoff with FF. Especially if you don't have long grass for gentle landings

[@murraykriner9425]

@@maxfliart every flight must be nerve racking as heck since you have all that effort in it, just one good crack-up and its all over. I used to fly U-control, gas control profile flyers, and destroyed just a few. Great job getting the balance right.

Absloutely beautiful airplane. You have so much patience, but the rewards are great. I'm a control liner from decades ago and trying my hand at R/C. I built the 'requisite' sailplanes and rubber kits as a teenager. I love building and bought a cheap Guillows model to try rubber. Thanks for the inspiration.

Thanks, probably made my day I’m going flying now 🙂

[@terryblackman6217]

Very interesting to see how you trimmed the S1. At first there was no consistency in the flite pattern. Let's hope she keeps her trim.

[@Steve-yk7iu]

You are a patient man.

[@garyruxton5226]

Helpful displaying all the trimming you did. With a little bit more, you can train it to come right back to you.😂

[@Glicksman1]

Excellent series of videos. So instructive to all of us who try to get these birds into the sky. Just a word or two if I may: I think that you would have been better off keeping an undercambered airfoil, maybe more or less so, but definitely undercambered. At lower speed and higher alpha, such as when climbing, an undercambered airfoil gains efficiency over flatbottom airfoil, the slower, and higher the alpha, the more efficiency is gained. Undercamber does not affect longitudinal stability and does not add drag until the airspeed is fairly high. This kind of mode is, of course, not a high airspeed type. However, adding under-camber moves the MAC (Mean Aerodynamic Centre or Neutral point) aft which means that the Cg must proportionally also move aft (but not too close to the AC) so that the stabilizer will maintain pitch authority. As you know, the distance that the Cg is forward of the MAC is crucial for getting the best stability vs. performance. Reconstructing the wing, making it lighter, etc. is a major change that in and of itself might result in increased or at last changed performance. By doing both that AND changing the airfoil, any change in flight performance thereafter cannot be reliably or accurately attributed to either. As you know, with all biplanes the angles of incidence of the wings both relative to the thrust or to the datum line, and to each other, plus the mean decalage of the wings makes an enormous difference in longitudinal stability and flight performance. Any misalignment of these crucial angles can be a great detriment to good performance. This model is clearly a leftie. It's likely as simple and annoying a matter of some slight built-in twist in one of the wings. Also, I suspect that this airplane's reluctance to climb may be a matter of insufficient incidence. The increased decalage that adding just a smidge of incidence to the top wing would add some nose up attitude, and would also, of course, increase longitudinal stability as well. A win-win. So many parameters, so many choices.

[@mikepalumbo4362]

Pretty model. All nice flights!

[@stephenpropnut7486]

Wow, fantastic tutorial on the FF trimming process. Thanks I never thought mythical fields of tall grass really existed! Not something we have a lot of in Oz unfortunately.

[@jimbo2629]

It’s very tempting to adjust the turn for both power and glide when on the field with rudder, when what it needs is thrust adjustment. Great video and a superb model. I originally wondered why you had a dt on a scale model.😀.Inspiring.
