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 KZbin. I learned a lot!

how do you make fiberglass so smooth and flowing without tons of filler?

Simply wonderful presentation. KZbin 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.

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.

A Master Craftsman.

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!

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?
