About the AR-5
Michael Arnold designed, constructed and flew this monoplane, the AR-5, in 1992 setting a world speed record and winning the Louis Bleriot Aviation Medal. He created these videos to document the process, originally selling them as tapes and then DVD’s. The collection is a study in highly efficient aerodynamic design and provides an explanation and demonstration on how to construct with composite materials. The AR-5 has been donated to the Hiller Museum in San Carlos, CA where it is on permanent display.
When Michael was diagnosed with cancer in 2015, he asked that his videos be posted on TH-cam to share with the public. He considers the AR-5 and these videos to be his legacy. He died October 2015.

The AR 5 In Action
มุมมอง 45K9 ปีที่แล้ว
"The AR-5 in Action", is not a "how-to" show, but a video record of the AR-5's return to flight status, an enlightening flight control experiment, two glowing pilot evaluations, a strange in-flight fire, a bunch of landings and takeoffs, and lots of beautiful air-to-air footage. Covering an eight year period, this video shows what the AR-5 was like in the real world. It's fun to watch.
Moldless, Low Drag Wheelpants
มุมมอง 66K9 ปีที่แล้ว
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.
Why It Goes So Fast
มุมมอง 288K9 ปีที่แล้ว
"Why it goes so fast", documents the efficient AR-5's record runs and clearly explains the simple drag reduction concepts used to achieve its surprising performance on such low horsepower. With comments by aerodynamicist, Bruce Carmichael. Great discussion on interference drag. Lists references.
Making A Molded Fuselage
มุมมอง 386K9 ปีที่แล้ว
"Making a molded fuselage-Shaping the AR-6" The AR-5 was made entirely without molds, but the AR-6 fuselage, cowl, and canopy were all molded. This movie shows the development of the master plug from which the molds were taken. It goes from pencil drawing, to foam model, to the carving, glassing, and finishing of the plug, and, finally, to the assembly of the carbon-fiber and honeycomb fuselage.
HOW IT'S MADE
มุมมอง 160K9 ปีที่แล้ว
"How it's made", details the engine installation and the airframe's novel structural design, and completely demonstrates all the easy, moldless, hot-wired, foam and fiberglass construction processes used on the fuselage, wing and tail surfaces. Inspects crash damage. The AR-5 from inside out.
Michael must have been very satisfied to see the volumes and years of math and handwork result in such a successful record attempt. Aerodynamics and laminar flow are so complex, it must have been hard keeping the focus from start to finish. Mighty impressive. I have a single invention to my name, a somewhat complex design and complicated hand build system of high performance electronics, about 2 years of my life, to be proud of. From that I can relate to how profound it is to see all that work result in the intended goal.
Hi thank you, your video has inspired me, 🎉
Hi great video and outstanding work, I have been a race car guy all my life, dabbled in model plane in time ,they didn't fly so great,your very clear explanation of aerodynamic I may take another look into them again, I have recently retired, thank you again cheers mate. 🍻
Wow! What can I say?
Rest in peace Mike, thanks for all your shared knowledge in your videos.
World record of what exactly is 201mph? 3:30
How does one go about transmitting a video “mechanically”?
Splendid, it’s cool listening to the theory after having taken aerodynamics this past semester
Love the aerodynamic details
My college professor said it was difficult to establish laminar flow even in the labs. He talked about circulating different geometries through a laminar flow fluid and how how it is to visualize. The layers are very thin.
Why do golf balls fly farther when the surface is dimpled to detach the laminar flow which slows a golf down. It seems to help the airplane wing. No classes in aero dynamics while I was in engineering school. I think university of Michigan is the only place in this state that has an extensive aeronautics and aerospace programs. Fill in some new info.
pretty cool!
N105AR for an AR5? Love it!
Absolutely fascinating! Thank you for posting this 🙂
This video really goes into detail, at a level rarely seen on TH-cam. I learned a lot!
how do you make fiberglass so smooth and flowing without tons of filler?
Simply wonderful presentation. TH-cam gold.!
Narration by Max Volume and Stars and Stripes Forever by The Naked Lady Wrestlers? Unless I've watched this before and don't remember doing so, I've seen his name and that group before somewhere.
This is the second time I've watched this video.I learn something new each time. Thanks Mike.
It's my first time, but not my last.
The Spitfire has that lovely curved fairing at the rear of the wing fuselage junction.
Built cars for frank costin, he said radius had to be no less than 1/12" on cowl /radiator openings, would 2" be better then ? and back, of car had to be higher than front, otherwise it wouldnt be aerodynamic. A brick is more aerodynamic, ie a bus with a cut off back, we put on a kamm back with sharp edge.

You should have added information on the power supply unit and the nicrome wire information.
Nice but CAD just makes everything better. I assume this is a lot longer than 8 years ago? I assume it's inspired by the sharp nemesis?
Brings back a lot of memories. I built a molded composite plane, and even though it had molded parts, there was still a lot of fabricated parts made from foam core that used the same procedures. I was working with vinyl ester resin and polyurethane foam, but the procedures were about the same. Except no hot wiring of the foam.
What are the performance numbers, cruise, top, stall engine hp.?

How do you decide on the GRP 'lay up' specifications?
Building experimental aircraft is so fantastic - I can't think of anything I'd rather do!
Congratulations!
45:13 For anyone referencing this info for a future build: This spot marks a serious error, which should be corrected for future designs. The C-channel wing spar MUST have the shear-web at the leading edge, and not the aft edge of the main spar caps. There is a very serious reason for this. Ironically, that very reason is being discussed here. But stiffening up the leading edge skin of the D-box is only a partial solution. By moving the shear-center forward, especially forward of the aerodynamic center, this will have a profound affect in improving aeroelastic divergence. Anyone who is confused by this observation, get a C-channel that can be flexed, even a tri-folded 6x6" scrap of paper. Mount the top and bottom caps and shear web to the corner of a countertop. And apply upward load on the free end. Observe which way it twists and consider how that affects the wing under load. Otherwise, very impressive build. Mike Arnold was brilliant!
STRUCK bye this video
Tu ta querendo imitar o projeto brasileiro do anequim né
Nice craftsmanship excellent video.
11:58 lolz the bugs come out and slow them down! are they serial clark?!
0:50 “when it’s working right”?! Lolz gotta love rotax. Apparently
Amazing work!!!
Incredible airplane, wish there was a kit or even plans to build the plane. Unbelievable performance 😮
"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." 👍
"Mike Arnold was a great builder for his time. He broke the model speed level due to slick percision work that was so strong and durable the crash of the AR-5 Proved his success of the The Foam fibreglass model. Arnold was ahead of his time. "A quiet Genius." I am glad he documented himself to prove his hard work and accomplishments was real. For to long many inventors were getting the dirty wash of their work and was not respected due to them not having a pattern to secure their item. It is an honor to view him at work, I know how he feels. I create aircrafts also, and I can relate to Mike and his construction team . Thank you for loading this video. I know Mike was a cool guy, his passion was this project; And he is listed as a teacher in my Book icons." 👍
Wow - what an education I just got! Many thanks.
It's in a museum? What? Tell me I've got that wrong? Ok yes but what an airplane, why haven't more of these been built?
2:15 It was a good landing!
I love that he designed this using pure engineering. No wind tunnels. No CFD. Just lots of structural and aerodynamic understanding. And then he implemented it with a perfectionist attitude and set a world speed record. Pretty neat.
Looks like Anton Chigurh retired to building airplanes.
Beautiful
These videos are amazing!
A 3D model and CNC machine would rip this plug out in a day. A lost art for sure.
Why It Goes So Fast Horsepower to weight ratio. Aerodynamics helps.
Soldered ferrule?! Ferrules are to be crimped!
But what happened to the airplane and all the damage?
