Giant race engine into a Bush Plane 😳13 Liters goes into Scrappy build # 29 

So stoked! One step closer, can't wait to fly together!

My granddad was one of, if not the, first pilots in Utah. He went to California around 105 years ago to become a pilot. He flew mail in a biplane in the twenties and was the piper dealer in the Rocky Mountain region. I wish that he could see what the humble cub has become. He owned three airports, Lehi, South Jordan and one in West Jordan and he and my Grandma were inducted in the aviation hall of fame up at Hill AFB.

Scrappy looks like a caricature of a bush plane, with every feature exaggerated. Amazing job Mike!!

Mike might be the most productive procrastinator ever.

Thank you for inspiring me to follow my life long dream of flying. 48 years old started flight school last week

I didn’t know “tubing notcher envy” was a thing, and now I have it...

I'm an ex-fabricator, and you, Mike, have me in awe of your Engineering and especially your fabrication. It looks all perfect ! I enjoy your site and your working on your planes. I flew for almost 20 years, and got to fly many different airplanes. Never had the chance to do bush piloting, but have put my Stearman into a few places, that have never seen a plane! Just wait until you finish Scrappy, and get it in the air! God-Speed Mike!

Imagining Mike laying in bed running failure mode analyses in his head over potential engine mount improvements. You Sir, are an inspiration to us all.

Mike: Oh, this job takes four hands? I'll just build two more hands. I'm dying to see how that airboat prop works out. Ron: Congrats to you, man. You know the path you were going down. Someone threw you a lifeline and you were wise enough to grab it with both hands and hold on and to make the most of it. I love all the background assistance you give Mike. Mike: Thank you for being wise and generous enough to see someone who needed help and to be that person throwing a lifeline. You are a good--very good--man!

The world's first flying engine.

Holy crap, that motor mount is a thing of engineering beauty Mike, you are doing so many cool things with this build. Thank-you soo much for taking the time to do all the videoing for us to watch as you build this wonderful aircraft. Filming , editing, all of it...thank-you. I love watching and your work ethic, enthusiasm and fun demeanour are so worthy of an audience. Cheers Jerry

Great video! Thank you for showing everyone that was involved. It takes a great team to accomplish great things and prior videos don’t always show that as much. We all know you work lean, but it’s still good to be reminded that you are working with and developing a great team.

Mike -- I think you should put some timelapse cameras up near the roof, pointing down. That way you can get timelapses of all the work you do!

I’m not often excited by internet builds....but MAN I can’t wait to see this plane fly

And here I was thinking: it's sunday night, maybe Mike Patey will let a video out today... and Bam! That's just awesome! You Sir are giving us a rare opportunity to see the behind the scenes of a very very very much unique perspective, so thank you very very much for that! Your skills and experience are just awesome! Cheers from Brasil!

Its really awesome see you and Ron work together. Thanks for all the hard work and taking us all along with you in this build.

Mike at start of series: "I'm gonna detune my ex racing engine to 500 HP - it's overkill, but I already have it". ... Mike now: " I'm gonna do some some engine upgrades, cos 500 HP just isn't enough".

When I was a child there was an elderly gentleman in our church congregation who was a F4U Corsair pilot during WW2. I thought that was the coolest thing! I know most of you pilots already know that the Corsair incorporated the largest engine available at the time, the 2,000 hp 18-cylinder Pratt & Whitney R-2800 Double Wasp radial. To extract as much power as possible, a relatively large Hamilton Standard Hydromatic propeller of 13' 4" was used, & thats why the Corsair had gull wings :)

Still the ONLY show I wait impatiently on. Everything else I binge watch. Keep up the great work Mike and Ron blessings to you, your families, and keep cranking

Mike made motor mount design unbelievably interesting, this man can do no wrong !! Where does one sign up for the Mike Patey airplane design & build apprenticeship scheme, seriously would be the best apprenticeship ever !!

The intro is perfect after that crash. "Its physics, math and engineering...." 😂😂😂

Mike, this motor mount explanation you gave convinced me. That you are THE modern day Howard Hughes. It was like rounding over rivets on the fuselage of his race plane, to reduce drag. Simple fixes to improve overall safety and performance. Genius! Just don't start collecting your toenail clippings. 😉🤪🤣..........🛫

Wow! Mike Patey and Scrappy on a sunday. What a treat. WOOT! WOOT! Looking good

Most manic “show and tell” on the web. Love the enthusiasm.

ANOTHER SCRAPPY VIDEO!!!! YESSSSSSSSS❤❤❤❤❤❤❤❤❤❤ KEEP IT UP MIKE

When I gave you a thumbs up, I was number 499. I find it an extraordinary testimony to your good work that there was no thumbs down.

Mike I hope your kids understand how lucky they are that they have a father that shares knowledge in this way. The depth and breadth of the knowledge you are sharing is amazing. Please please keep on sharing even if it isn't plane related. You are a great teacher. My you and yours be blessed sir :)

Thank you for the update video. Looking forward to it's first flight. Hope the family and you are doing well. Take care Spin

I swear every time I have something to do Mike comes out with a new video so I have to put everything on hold

Mike Patey's Scrappy build are the best aircraft/creative/master engineered/intelligent/fun videos on RU-vid. No tip from Mike is to small, and all your explanations are always welcome. Thank You for sharing the adventure and fun!

What can you say about that video? Absolutely Amazing! To think you're watching the most amazing, customized plane, being build from the ground up. Not only does anything not come close to Mike's aircraft designs, but nothing comes even close to this video series. Thank you and please keep'em coming. I cant get enough.

Your designs are so far ahead of most aircraft builders, their just shaking their heads saying what? Grazy good stuff Mike!

I have been known to click to the good parts...but with Mike, its all good.

"What sort of standards is this airplane built to" 'Oh, Very rigorous aerospace standards' "What sort of things?" 'Well the front's not supposed to fall off, for a start.'

I'm in love with the thought process behind the angled engine mount bolts. Genius!! Well done!! Such a wicked project.

OMG Scrappy is looking so rad! Fantastic build!!!

Love these! Scrappy is gonna be awesome!! 😎

This is probably going to be the best bush plane ever!!

Thanks Mike, another great video, you give so many of us so much pleasure!

This dudes work ethic is crazy. Dude was sitting there ready to put his plane together and was twitching about painting his mount. Lol wish i was this motivated to work.

Two years into my aircraft build, and I’m finally finished clecoing my pre-punched empennage together.

Just by watching Mike's videos i went from having a skeleton airframe in my garage to a fully covered one almost ready to paint in a week. 😆

It is so cool to see how far Scrappy has come since you decided to do this project. Watched every episode. So cool man!!!

This format of episode is where it's at! Thanks Mike for the excellent content!

That trick with the nut is genius. Now I just need a real plane to work on lol.

Thx for the extra tip at the end!!

This plane and concept are really awesome. It is so nice to hear the thought and planning that goes into each step. Amazing amount of detail goes into building an airplane in general and his creation is 10 steps ahead of anything else out there. Wow!

You're making me feel better about my welds! I've been hanging so see more of Scrappy so thank you for posting! :)

Mike Hi! I have followed you for a long time and have watched all of your’s & your brothers videos. In fact my wife and I own a Bravo 5 tug #18. At any rate have you considered making your engine mount so that you could actually swing the engine to the left or right to access the back of the engine, like you can on a Cessna 195? We had N195JJ a 1952 Cessna 195 we found in a hanger in Springfield Ohio and restored, loved the fact you could pull to bolts and swing the engine like a door to access the back of it while still mounted to the plane. Britt

About losing the engine, I heard of a guy flying along with his family in his Miles Messenger, when the prop shed a blade - a few moments later the engine fell off, and he got very busy putting his wife and kids on top of the instrument panel - and they all survived.

Amazing work Mr. Patey.

One word, genius. Framing of motor mount is very strong. The entroduction of the beaver on floats breaking the motor mount set the story.

When Scrappys finished, you need to collaborate with Flite Test and make an rc model. Trent's freedom fox is sick but an rc scrappy would be bad a**.

“Motor mount jig adjuster thing “. So technical!

HEY MIKE, YOUR PLANE LOOKS GREAT, BEEN FOLLOWING SINCE THE START OF DRACO, REALLY ENJOY YOUR PROJECTS AND APPRECIATE YOU PUTTING THIS CONTENT OUT. I KNOW YOU COULD SPEND YOUR TIME AND MONEY A MILLION OTHER WAYS, IM GLAD YOU CHOSE TO SHARE THIS WITH THE WORLD. ITS AMAZING THAT A SMALL TUBULAR STRUCTURE CAN SUPPORT ALL THE WEIGHT OF AN ENGINE CANTILEVERED OUT THERE, AND ALL THE ASSOCIATED FORCES FROM THRUST. TUBULAR TRUSS STRUCTURES DONE RIGHT ARE IMPRESSIVE!

I learn something about engineering, aviation and artistry every step of this build. I so look forward to Trent Palmer documenting future shenanigans with Scrappy.

I'm an Engineer and learning a great deal .... Thanks for the explanations, I'm tracking what you do and why.

Everyone! Drop everything! We have an upload! :O :D But, after that - *Back To Work!* ^^

Very exciting to see your progress on this. It was fun talking yesterday at Wings and Wheels!

This series of videos is just so cool. Absolutely love watching you work through these issues, as a extremely competent journeyman builder you have my respect. Plus It's going to be so cool to watch it fly after you've completed it.

"More to come" so true and hope so! Love in scrappy but cannot wait for draco x

It is YOUR SON'S project that I suggested be called SCRATCHY! Then when you fly over him as he is shredding the water it will be SCRAPPY and SCRATCHY! -✌🏼

Your ingenuity is matched only by your attention to detail. I keep on saying this, but you blow my mind even more with every episode, Mike. Wonderful work!

Brilliant design with the bolt angles. This show is a treat for builders of any sort.

Hey Mike, are you OK... We're starving out here for a Scrappy update!! I've had more updates from my vendors than you and they're doing things we've never done before... Love ya brother, just going through withdrawals and getting worried you caught the COVID.

the difference between Mike and the rest of us: What I did today - I watched mike build a plane. What Mike did - I built a plane... lets get to work!

Mike, You're an inspiration to many of us. Don't stop.

I’m IN LOVE with this plane, it’s so cool you had an idea in your head and made it a reality for all of us to enjoy!

This guy is building a real plane that will fly like a RC airplane!

I'm with you on the double motor mount . That engine is going to be a beast on that light air frame . I'd hate to see it take off and leave you and Scrappy hanging in mid air . LOL I had a Honda CR 500 works bike shoot out from under me once , I felt like Wylie Coyote sitting there on nothing but a cloud of dust ! THEN , my tumbling ass ..... Luv you guys !!!

You never cease to amaze me, Mike! Can't wait to see Scrappy fly!

Your motor-mounting solution is well applied physics & really sturdy. Good work!

Puts into perspective all the so called aviation 'experts' with their goofy opinions on what you should or shouldn't do. If it works then fine, if it doesn't try another option. This guy has all the right ideas..

This is what we’ve been waiting for!!!

That engine mount should be patented, gold plated, and put on permanent display at the Smithsonian. The amount of "this is good, but what can I do to make it better" ingenuity is incredible, and yet seeing it all together, it seems clean, straight forward, and obvious. I caught myself thinking "well of course that's how it should be done" several times, (helped by Mike's excellent explanation). I bet there are builders who watched this heading to their respective workshops and drawing boards to incorporate the engineering details from Mike into their own builds. If there aren't, THERE SHOULD BE!

Awesome video, Mike! Thanks for it! A Cradle - you built an Engine Cradle. Really looking forward to your next Scrappy video!

Average Joe engineer - just bolt your engine on like that. Mike Patey : Here, hold my beer!

Hi Mike! Love the videos! I’m rebuilding a kitfox because of watching your videos!

Can’t wait to see another scrappy update! I use a ton of RU-vid and this is one of my favorite channels! Can’t wait to fly one day!

This is beautiful work. Great design!

Mike, you are insane in your thinking and I love it! Very innovative forward thinking! Thanks for the update on Scrappy. Would love to know where your wife is on her "baby" as well, will she be doing a vlog for us to follow?

WatchedTires squash when motor weight was droped on em i noticed. What a beast u have there.

This is such amazing viewing, I'm not necessarily watching any in the correct order. I first come across Draco and Scrappy on RU-vid whilst watching other pages as I want to learn more STOL techniques. Not knowing some of the drive behind the tech was also search and rescue and now watching some of this build etc, I can now see why the other pages and pilots have so much respect for you and your family/team and what you accomplish. Thank you for transparency and inspiration you are giving ✌️ You certainly earned my subscription

I have watched this build from the beginning and so excited we are almost ready to FLY!

I think MIke's the only person that's said that 500 horsepower isn't enough on a bushplane.

And to think this is what he does in his extra spare time what am I doing with my life!

Finally! So awesome to see the engine on. I still can’t get over that prop. Insane.

Your excitement on what you do is unparalleled. It is said that if one’s work is one’s passion... then you really don’t work...or something like that! Is it necessary to have a background on aeronautical engineering to do what you do? In any rate, it’s fantastic. Absolutely amazing watching the progress of an airplane coming to life. I found this video by accident, now I look forward to see the result of Scrappy in the air. I’m an instrument rated pilot. Best regards and success on your endeavors. Cheers from Houston, Texas.

Every time Mike does a fist pump, a pilot gets his wings!

This is no Cub. It's a full grown badass grizzly.

I really like your explanations about the need for identifying weight distribution. And the motor mount design. Makes it easy to understand.. Thanks.

Mike, it’s good to see you “back to work!” I enjoyed your explanation of how you designed Scrappy’s engine mount to be “fail-safe” as well. But in your talk about the consequences of engine separation you’ve backed yourself into a corner. If that should happen, you didn’t mention your own backup plan of your BRS system! I agree it would be a “”recovery from an unusual attitude,” but you would also have the entire rear fuselage as a “crumple zone.” Mike, you and your whole family/gang are an ongoing story of imagination, sweat, joy, dedication, that is a constant challenge and inspiration to all of us! I am looking forward to your finishing and flying of Scrappy; plus Chandras’ Carbon Cub project, and “anything else that might come up!”

ever hear of overkill? mike: "yeah, it's my SOP"

I just can't wait for the wings to get build bud i have watched every vlog now i cant wait to learn how to build wings can u give us ones that don't know how to do the math on building a aircraft

Congratulations - big milestone with the Scrappy build.

Mike, fantastic video, that motor is huuuge! I’d love you to do a separate video to walk us through how you: a) calculate the weight and balance and therefore the final mounting position of the motor, b) determine the thrust angle for the final position of the motor and c) the strength of materials calculations for the design of your engine mount taking weight, thrust and shock (from the off-field landings you plan to do with Scrappy) into account. Thanks for taking us along on such an amazing journey of building your Monster Cub 👍

After losing a prop blade while towing a banner, three mounts broke. The fourth bent 60 degrees. The cowling flew off never to be seen again. The weight of the engine remained but it was hanging off the right side of the plane blocking airflow to the tail. I followed the yaw to the right and glided like the proverbial set of keys to a one acre field. A flare wasn’t possible with only half an elevator in the slipstream but there was no fire thank God. The engine completed the 180 on impact and the remaining prop blade pierced the cabin and ended up wedged between me and the panel. ( it did NOT pierce me. Another thank God). A couple weeks in the hospital and I bought a Pawnee with the insurance money and went “back to work”. ... undetectable stress fracture in the prop.

Me: geezzzz 500hp on a cub is gonna send the thing into orbit Mike: 500hp isn't enough

WOW, and thanks for yet another awesome video Mike.

Pure genius!!!! Your idea on having the motor mount bolts at angles is top notch!!!!!!!👍👏
