Mike Patey Interview (Scrappy Build)

[@garyhardison1275]

As usual Mike keeps us glued and clinging to threads waiting for the next video! Cant get enough of this!

[@gonun69]

"I'm in my 'little' crazy dirty mancave" dude, that's the biggest mancave I've ever seen! My house would fit in there!

[@kevinbrickley2767]

need weekly scrappy build vids back to work

[@darkhorsegarage9623]

Just like a giant model airplane. I have used paper tissue and dope then covered that with monokote to make a super smooth strong wing covering. Love these short quick videos. Keep them coming

[@InquisitiveSearcher]

Mike, I look at that engine and prop and images of Road Runner cartoons of my youth come to mind as this airplane build reminds me of something that Wile E. Coyote would dream up to catch that bird. In the cartoon taking shape in my mind the engine revs up, the brakes are released, and the fuselage takes off like a shot and leaves the wings behind. Nothing ever worked correctly for that coyote.

[@MrHansen]

Crazy project that is going to have crazy performance. Thanks for the video!

[@adamsmith5913]

That fan boat prop makes me smile, the plane is going to go up like a helicopter. This one will actually be the rock crawler of the sky, big block and king suspension?

[@hoppermantis7615]

Wondering how this one will be handling insane crosswind. And if he is going to throw wing spurs on this one as well?

[@MattThornton87]

I nearly dropped my coffee when he unveiled that prop!! Can't wait to see it fly

[@oneandone2744]

This is going to be a great project. Leonardo's "Universal Man" never sleeps.

[@MrJolppy]

I wish I learned on that came to Utah I would love to learn how to do it

[@flyonbyya]

Fabric has been in aircraft construction from the absolute beginning. Aren’t there more advanced material options for this purpose? What’s the advantage of fabric over other material options....weight? What are the disadvantages of utilizing fabric as a choice for this particular project?

[@warrenmatheson563]

Weight and ease of repair.

[@hoppermantis7615]

Wondering if Kevlar wedged Aluminum would have been a better concideration for longevity. For such a mongrel monster.

[@mysterymete]

@@hoppermantis7615 Kevlar is heavy.

[@balsumfractus]

Fabric on control surfaces is lighter, and makes it easier to balance them....that's why it was used on planes like the Corsair with 4 times the power of Scrappy. It is also fairly easy to work with, and can't be beat for going around compound curves. Linen and cotton was used in older times, but they are likely using a synthetic fabric.......

[@hoppermantis7615]

@@mysterymete And its a bush plane on top of debris. As well a Prop, near a finger of the Gods. Everything is a balance. Also I'm into longshelf designing... Not demand.

[@privatecautious3643]

YA GOTTA WONDER IF 500hp will make it hang on the prop in vertical climb? at least for a while Rodney

[@txfreerider]

With that airboat prop, I wouldn’t be surprised.

[@flip66five]

@@txfreerider or maybe he throttles up and blows the wing and windscreen out...

[@snowgorilla9789]

About how much does the fabric shrink and does it become brittle if you screw up and overheat an area ? Thanks

[@StewartSystems]

The fabric will shrink approximately 10%. If the fabric is heated over 375°F it will crystallize and it will not have memory. In other words if the airframe shrinks because of a temperature change the fabric will not. It will become loose. It is very important to never heat the fabric over 350°

[@waynep343]

i want to know if 2 layers of medium would have been better if the under layer was installed on a bias.. if that might add to the final strength of the cloth coverings.

[@StewartSystems]

That is an interesting question. I think in some ways it might. But it would be difficult to test. When we test the fabric for strength we do it was a pool tester. We would normally pull it straight in line with the weave. The way we are doing it now we would be pulling two layers of fabric in line with the weave. If we did one on a bias I think a conventional protest would probably show it weaker. But in the real world it might actually be so much stronger overall. But the reality is that two layers of medium fabric is so ridiculously strong it’s kind of a moot point.

[@waynep343]

@@StewartSystems thanks. I take it that you know mikey and Joe up at buffalo are starting to build new wings for a replica DR 1 and a Fox Moth . There was a great video of a brand new jetliner doing cold weather certs at -47C. When the new jet was ready to take off. They had to wait for a 70+ year old Curtis C46 to land from its daily cargo flights no matter what the temp is.

[@gvrose1]

Your going to have so much torque from that engine that Scrappy is going to spin on its longitudinal axis. Hahaha ha. I am enjoying your channel and expertise!

[@troy5007]

Hi mike can you tell me where to buy those propellers in the back ground ? I am looking to build a quad drone - manned. And I am looking to use the type of propellers you have in the back ground thier. Thank you any help would be great 👍😀

[@Rourke-Slimer]

It's a propeller off a racing fan boat. Not intended for aviation purposes, but that's how Mike rolls.

[@jasonsneed3179]

If you are talking about the fat 4 blade, it is an air boat prop.. You are are talking about the 2 3 blade props those are for mine and Marks airplane (Ambush and Deception), they are Catto’s...

[@challenger2aircraftadventures]

Would love to see a more detailed account of what method was used to cover Scrappy, if it deviates from the norm. This was a great "tease" video, now where's the meat and potatoes one?!

[@StewartSystems]

Peter Toth More to come!

[@ChandraSlyFoxPatey]

Peter Toth Video is on the way. I and my friend covered a few parts and it went beautifully! 👍🏻👍🏻

[@kevinsavas7173]

Oh ya. Go my Mike and scrappy fix!

[@baggerf14]

Why not make the tail skins carbon fiber?

[@troyedwards5233]

baggerf14 Yea, Y Not!

[@jasonsneed3179]

The horizontal is carbon, Maybe some Kevlar also I don’t remember. Rudder and Elevator are fabric.

[@leberkassemmel]

Who thought it would be a good idea to publish this video without listening to it with stereo headphones before

[@hoppermantis7615]

I almost missed this.

[@richbuckley6917]

Design change: build in air breaks. 2 seconds before Scrappy touches down at the end of a run, cut power and pop the air breaks. It should reduce turnaround time by 20% +-

[@ericlayton6]

That prop is all the air break he’ll need

[@richbuckley6917]

Eric Layton Yah, you’re probably right about that. Besides, I can’t think of a light weight easy to operate airbrake. All together the upper and lower air break would end up being way smaller than the fixed prop brought back on rpm.

[@jamesburleson1916]

@@richbuckley6917 There's also the bit where the plane is designed to stall at ~30mph, and air brakes are not terribly effective at those speeds. They work great at higher speeds, but it's sort of an exponential, and 30mph is on the flatter end.

[@richbuckley6917]

James Burleson good point

[@RCjunkie]

they are useing the same we use on our RC planes!!!

[@richardpotgieter8713]

Hi mlke awesome channel can't wait for the necks episode . There is 2 you tube channels that may interest you ,its about a car engine that developes 600bh power ,3 cyl twin turbo. You tubes channels are Drive tribe 11/3/2020 and Engineering explained 18/3/20 .The company builds the eng is Koenigsegg cheers

[@InquisitiveSearcher]

I think I read somewhere that it only weighs 75 pounds or maybe that was kilograms, which ever, if that is true it would be amazing. To get 600HP our of a 75kg engine! It would be easier to balance Mike's cub.

[@j.g.92]

"...maybe steep climb... I dunno." 🤣 Haha! Yeah, sure Mike. 😂 But I suppose, could argue vertical isn't technically a slope.

[@DanielSwick]

Awesome

[@freddy7700]

👍 👍 👍

[@MrBarbuster]

need ujr thinkin cap steve henry took FIRSTTT place at texas stol

[@vancamjr]

Fluff...is that the new plan for this channel? Nothing taught, nothing learned.

[@ChandraSlyFoxPatey]

John Van Camp I and my friend covered a few parts for Scrappy. It went amazingly well, we used some techniques I think you’ll find interesting, a bit different. A more detailed installation video is coming on Mike’s channel soon.
