Moldless, Low Drag Wheelpants
Вставка

- Moldless, low drag wheelpants" is a close-up study of the design and fabrication of the AR-5's custom fiberglass landing gear fairings. "The cleanest landing gear I've ever seen", says Bruce Carmichael. Each wheelpant weighs only 2.35 pounds. Every step is shown, from initial research, through foam carving, to paint and installation.
Mike is the Bob Ross of the fiberglass world.
Or Rembrandt🤗.
Spot on!
Mike was amazing in so many skills: engineer, builder, educator. The time and effort he took to share all this with the rest of us is priceless. So sad that he has passed. Best wish's to his family.
I get the feeling the mispronunciation of duct tape may have gotten right under his skin. The lesson I have learned from his generously shared legacy is that patience and perseverance with a good dose of humour can yield beautiful engineering. Brilliant man, thanks Mike, RIP.
I am just floored. I love these videos. The amount of detail of explanation is amazing. That flange is beautiful. The 4 ply bag wet idea, genius. Love it.
Robert, in answer to your question about downloading the video. Mike Arnold passed away in 2015. When he got sick, he decided to post the videos on UA-cam as part of the public domain instead of selling them as he used to. Hence, I think it would be find to download.
What an excellent video. I was looking for how to make a 'streamlined' body for a human powered vehicle (bicycle), and didn't want to have to make a buck. This totally explains everything I needed to know and more, slowly and precisely in a way that a newcomer to fibreglassing can understand. I came here from your video about the fuselage. Thanks for sharing. Regards Mark in the UK
Dont fly but man these old vhs' take me back to the 90s. The camcorder the grain the way Mike talks and explains. Its just feels like home
Those wheel fairings are absolutely awesome!!! Now I’m completely discontent with my bulky, heavy, mis-shaped fairings. His methods are so excellent. I hope to upgrade mine some day by copying Mike.
Состарился занимаясь любимым делом,счастливый человек! Мое безмерное уважение.
Beautiful craftsmanship 👍
I found the book: Fluid-Dynamic Lift, by Dr. Ing S. F. Hoerner. Thank you for the excellent video.
hoerner is based
My favourite line, 19:46 "...I make the shape I want by just looking at it .." lol Old school rules. Great video's. Thank you so much!
"Arnold was a star, and he did not know he was a celebrity. He explained everything, and everything he did worked. He was a good engineer." 👍
this is an old video but I still learned a ton that I can apply to my project , a battery box for my e-bike . researching on this CF project of mine I learned that plug making is key to getting a great finished looks , aerodynamics is not as critical as it was for your project but will increase my Km / Charge achieved . the looks is what I am after ,Thank you for sharing all this knowledge tricks + tips about molding , Fly safe and be well Cheers …. TY =D
This guy is without a doubt a genius.
Mike is clearly a genius. May he RIP.
Thank you for sharing these wonderful and very informative videos!
Thoroughly enjoyable dont remember being more interested in a video, great job!
Once again Mike... beautiful sculpting and fab. Not a vid series I'm liking better than yours~!
I want to interject here that I was totally destroyed while watching another one of Mike's great videos, to learn that Mike had actually died in October of 2015. I believe the person adding that comment indicated cancer had take Mike from us. For those of us who truly enjoy the intelligence, thoughtfulness, and quality of his videos, as well as just flying buffs, in general, Mike's passing is a huge loss and it will be some time before anyone will be able to step forward to replace him. I am sorry for the bad news but wondered why I had not seen and new videos released lately.
That's sad, Mike, obviously was an Artist in work, and it's apparent He loved to share his life long learned skills with others.. Certainly, a fabulous Man.
I might have been the poster of that news on his other video. The family made these videos publically available. I was a huge fan of his AR5. When I came across these videos I looked for what Mike was up to, I found out about his passing. Not much was mentioned. He has no social media presence. I think he should be more widely recognized and honored. As I posted above...
Mike passed in 2015. Here is a link of how great this guy was to aviation design, fabrication and art.

totally amazing . loving this work
Also love the look of that old brown epoxy
TBH, I never realized just how 'experimental' experimental aviation really was.
Inspiring to see what can be done. Of course today, we are advantaged by 3D printers and peel ply.
One thing I was wondering about gear, rather than a steel tube with sliding suspension why not a carbon fiber blade with a trailling arm rollerskate wheel. If you are going high performance and only flying from firm runway and it's a light plane, you don't need a forklift size wheel.
Such amazing skills
Thanks for the this composite education video
Saran wrap can be useful to keep stuff from sticking, and if you're careful, it leaves nice smooth surfaces.
wax paper also comes in handy
Thanks for the this education!!!
Beautiful, Removing the foam core is a lot easier with Acetone. It just melts it away..
That beautiful job, was probably a set of $8,000 wheel pants..
Not with polyurethane
1:02:12 we got about 1/8th of an inch gap here... That's insane precision
If I could have a friend to replace Mr. Wilson on a lost island, it would be Mr. Arnold !
Years and years of knowing how to preplan.
Hi I see what you are doing with the micro smooth past but would it not be quicker with simple cheep 5 minuite bondo I have made many things for molds and used this cause it's quick , fills weave in cloth ,and epoxies well , very good videos you make and enjoy watching thanks
The comment is old but for the sake of future readers he did not use Bondo because it is considerably heavier than micro.
Hi,
Thanks for this great video. Do you have a video about finishing a composite aircraft and how to get those smooth surfaces on the wings?
Id love to see something like that as Im in the process of finishing an aircraft now.

Hi, Tony. Unfortunately Mike Arnold passed away in 2015 and along with him all his amazing knowledge and skill. I wish I could provide you some direction for your question.
Sara Arnold, Michael's sister in law
Hi Sara, Im so sorry to hear of your loss. Mike was such a great contributor to aviation and Im sure his work, enthusiasms and amazing skills have helped many people to achieve great things in their own lives. I wish you well.
I like the fun part
I'm really enjoyed watching this video, and rest also. Because, it is really highly educational from designer & inventor from the owner of this video.
May i download this video, as educational references, and i do hoping that the owner of this very educational list's of his video ---- with his permission.......
I would like to download it for my references. Hoping you may grant may request?....
And thanks in advance Sir, allowing me to download it for me.
May I ask about the "Horner" book you have for reference? I would like to purchase a copy. I am building an Avid Airedale and would like to add pants and a center belly pod.

Hope this helps
i wonder if one could digitize the wheel pants shape and carve the plug out of foam or soft wood with a cnc router? just a thought GOOD VID THANX
bowlweevil Mike passed away in 2015 of Cancer. The plane is in a museum, not flying. Not much chance of scanning the shape.
@@jenniferwhitewolf3784 what a great loss of talent may he R.I.P.
Not understand why a single side wheel construction, because that gives a bad moment when the weel meets a stone or so; also more weight and more wide. Also a bad torque as braking. A reversed U over the wheel, central placed under spring holding axle (half motorcycle frontfork) means less weight and much more stabillty.
Sorry for my bad English, I'm Dutch...
it's an aerodynamic optimization, as the intersection between the strut, and the wheel fairing has less aerodynamic drag when the side of the wheel fairing is aligned with the strut.
the plane was built to beat a world speed record for it's weight class. other than that, you are right, of course.
it's the price to pay when you optimize anything for one purpose.
Plus one on the previous statement. Think about all the main landing gear on most light aircraft the wheel is cantilever. Off the landing gear leg. Usually on light aircraft only the nose wheel has a fork where the wheel is in the center of the landing gear strut. You have a point on how the gear would react with drag or hitting an obstacle but this is all about aerodynamics. You can make the landing gear strong enough to take that moment or twisting or load.
He explained it in the video. It was to optimize laminar flow. A U arrangement would have made the strut cover too wide and would have added more wetted area drag.
They don't look much different than a set from aircraft spruce. I'd have just got those and saved all that work.
AND...IF...youd gone to your local aeromodlers club you'd have found all this out in 10mins...along with better ways of molding one offs...we were doing this back in the 70s...bit with even better laminates than glass cloth and heavy epoxy or polyester resins :-?
For cripe sakes, this is historical video. Of course materials and processes have evolved.. its been over a quarter of a century!
@@jenniferwhitewolf3784 back in the 70s...forward to now...& everyones stuck on bloody epoxy...tunnel vision
@@Errol.C-nz Get over it.
@@jenniferwhitewolf3784 the word is devolved...regression as opposed to progression
@@tigerseye73 its fine for those going backwards...more advanced in the 70s
