Hanging Electric Mountain Bikes from an Airplane's Wing | Scrappy #56 

All day Mike drills holes in metal, then bolts them together. At first it’s boring, but then it’s riveting.

The holes are for hanging stock carbon cubs from the wings... duh... 🤣

I love how at the start of this build "OH I'll name it scrappy because I will reuse a bunch of old scrap parts" turns into "This is Scratchy, because every bolt is built from scratch"

No, no, no...Mike, before you skin those wings, we want and episode with Cub Crafter engineers looking over your creation. I can't imagine their reaction, but I'd love to see it

Mike: "this wing pylon will be for mounting miscell-" Me: *excited gasp* Mike: "-aneous things" Me: aawww....

The holes are very clearly for the flux capacitor lines. You're not fooling anyone time traveler Mike. ;-) It's the only feasible way you get so much done. :-) -Daven

That cluster of holes is obviously a Play Dough extruder. Is every high Tech plane needs one.

In the next episode: "ive decided to mount this 4 brownings machine guns to avoid bird strikes"

Man building a cutting edge aircraft says he’s “blown away”… priceless. Addendum: I can’t help but smile because of your seemingly boundless energy and humanity.

If those holes in the spar aren’t for mounting a JATO system, I’m going to be very disappointed in you Mike!

A huge fuel pod in case I want to cross the Ocean, he say's casually.

I will almost bet every engineer at the Carbon Cub plant watches every one of your videos Mike for new Ideas.

I am going to guess the holes are for a wing mounted drop system. so he can drop supplies while performing search and rescue. just a note, I have officially started on my adventure to join you all in the skies. I did my discovery flight last Thursday and officially start my PPL training Wednesday. maybe someday in the future I can touch down at SPK and stop in to say hi.

This is literally one of the most impressive personal projects I've ever seen. From top to bottom, craftsmanship, engineering, drafting, and ingenuity. Id love to hear from mike what it would take to hire all of the r&d and machining work out. The money, time, and reworks. Just the initial meetings alone would last a year.

Funny how the airboat prop has become the least crazy part of this build!

hey Mike have you ever thought of doing remote thermal imagining pods on the wings for search and rescue? Make it is you have a camera out under the wing that can rotate 360 degrees horizontally and move up and down so your co pilot could be watching the feed from those while you perform your search pattern? You should talk to Trent about doing camera setups as well.

Don't let him fool ya, he is really mounting missiles off the wings!

Weird holes: probably to hold actuators and power transmission elements related to changing wing form.

"I'm making a slide, billet aluminum, miscellaneous attach points, so I could carry guns, moose, elk, deer, bison..."

Out of curiosity, do you make Mark guess these things too? He's the one guy who actually knows how you think!

The special holes are for a special 360 powered articulating camera gimbal that will have a Multi sensor 40x Zoom / FLIR cameras that will look for heat signatures on the ground and auto track hot spots (people) for search and rescue ops! It will add the counterweight for the mountain bike.

The holes are for outlets to charge your electric motorcycle!

Holes are for ‘lasers’ to engage warp-drive

Mike, you've given the term "home- built" an entirely new plateau.

My guess ; Little holes in a cluster on leading spar is for a slat actuator motor mount.

Somebody on your team has an excessive amount of looney toons knowledge... This person needs to be revealed.

That’s a huge wing, this aircraft is going to be a beast.

I guess those holes are to accommodate variable wing geometry system components such as pivot points and actuators

They're mounting points for the actuators that grow and reshape the upper surface of the wing😀

Drop tanks confirmed, scrappy will have insane endurance.

The holes are for your flexible geometry wing mechanism…….or they could be the electrical output connector holes for the nuclear reactor you are scratch building, to power your camp lights.

Knowing how crazy you’ve gone designing Scrappy so far I’d say the holes are probably for mounting an external fuel tank, a military grade FLIR camera, JATO system, and a Skyhook… Per wing.

This is like Saturday morning cartoons for adults

Whenever you say “gosh, that’s a lot of talking…” I’m really surprised to realize how much you had my full attention

There are no words available to describe how much I love and appreciate this man. Mike you are an engineering superhero.

I have no idea, but the arrangement looks suitable for a rigid torsion control connection, potentially even for an in flight wing flex/torsion adjustment by manipulation the lever end of a torsion bar to work like a dynamic sway bar on a vehicle.

If Mike Patey and Elon Musk teamed up they could finish Starship in a weekend 😂

Hahaha “designing new wings... designing new wings... designing new wings”!!!!

Scrappy: The only plane with provisions on the wings for armament and recreational activities.

Mike you do know this is going to bug us for days till you reveal what that cut out is for I'll not be able to sleep thinking about it love your videos 👍🏻👍🏻👍🏻👍🏻🇬🇧🇬🇧

The holes are for mounting 50 cal machine guns

Mike, you should include more content featuring part design on solid works. It seems to be such a crucial part of your process, but we mostly only see the end results.

I have absolutely NO idea what those holes are for, but what I DO know is that this is one of the most inspiring channels on youtube. This energy is contagious! I can't wait to own my own bush plane one day. Thanks Patey!

I love how humble Mike is, how many time have we heard “it worked perfect, I can’t believe it!” And everyone watching thinks to themselves “we can!”

I've wanted to build an ebike to match scrappy... maybe this needs to happen.

The holes are for “tendons” much like prestressing in bridge construction. On second thought, after seeing the trial install. they are to attach brackets for recessed lights.. Haha third edit, upon further reflection, I cannot presume to even have a clue,, Mike 😂 ..... Alright 4th edit. Its possible that Mike cut random holes to get far out ideas, and collectively invent something entirely new. The warp drive is my personal favorite.

A “huge fuel pod“. I see a world record plans in the making!!

Hey Mike,, Why don't you attach 2 tiny all glass pods, 1 on each side for a person to enjoy full view :) Crazy Idea.. lol

Wait....what if Mike doesn't actually have any plans for the holes, and he's just going to watch for the craziest suggestion then do it????!

Hello Mike, Retired structural engineer and rookie pilot here. Have no idea about your mystery holes but as some have suggested maybe they have to do with your wing surface optimization. Would like to add that the intersections of truss web members to the chords of trusses are “panel points”. You explained where concentrated loads may be applied well but seemed you were looking for the term. And one other thing is that without diagonal web members in a truss, you will still have a Vierendeel truss, although not as stiff as other trusses with diagonal members. Sincerely, Will

So is this the introduction to your new company "Patey's Planes and Engineering". I would buy a Patey plane for sure! Love your new fighter Mike!

When Mike first announced he building a plane from scrap, I was like, "this is going to be the coolest Carbon Cub ever. Boy, did I ever underestimate this project!!

You know, after watching this with Scrappy, I'm almost afraid to see what Mike is going to do with Draco X.

So I'm assuming the curved slots are a hint the wing tips will twist. Also the front spar is longer? I'm a rotorary wing guy (gyros) so no idea really how big wings are made. Anyway just speculating about a hypothesis.

Flour bomb drop system and S.E.A.T. fire retardant drop system!

You, Sir, are the Kelly Johnson of experimental aviation. Your creativity and willingness to explore options that know one else would consider are outstanding.

Scrappy will be the focal point of Oshkosh,a remarkable airplane designed by an aviation genius and a really nice guy prepared to share his ideas,and look how quickyl this is going together !

Great Job Mike! I've worked on both the F4S and the F/A18 and don't think either was as well thought out and engineered. Your mechanical engineering far exceeds my electrical engineering.

It’s great that you had zero “fine tuning”, Mike! With most of my projects, I seem to have lots of fine, medium, and even some course tuning... Your attention to detail is over the top as always!

Hopefully I get a response but do you think scrappy will be ready before oshkosh 2021? Would be so cool to see it in action

I wouldnt be surprised if these weird holes were for some kind of rocket engine to make scrappy take of even more vertically... But then it would be called Rocky and you would run into copyright issues 😂

" ...crossing an ocean.."got my attention.

The 6 holes are for the linear actuators that will provide the variable wing chord. One of the reasons the wings structures are so beefy are they need to take the load of a radically large chord. This plane might fly as slow as 15 knots or so in slow flight config.. Amazing Mike and crew!

My guess is all the extra holes he drills is so that he can make a wing that extends out and in. So that when he wants more loft and slower speed can extend the wing out to be longer. Faster, pulls the length of the wing in shorter.

Hey Mike love the engineering going into this I’m not an engineer by any means just an aircraft mechanic but Ive been noticing some slots on the top of the spars and I’m curious if your are doing something I’ve always wanted to see done and that is an adjustable top camber wing??

Watching every one of your videos mentally exhausts me, with your engineering prowess and thought provoking mental projections on ‘what if’s’ ! I’m never surprised when your engineering projections are absolutely accurate and all the parts fit like a glove ! I salute you sir !

What are the holes for??? Guns! Cannon! He's making a CAS platform.

So, now we see what took so much design time. Kind of like a chess game, thinking 5 moves ahead. I bet you have incorporated ideas you have been dreaming about for years. How many hours on SOLIDWORKS so far? Any idea? Your work and videos sold me on SOLIDWORKS. I have it now, just have to learn how to use it. Fun!

I've learned never to question Mike. This man put more thinking into his ideas than video will ever show.

Oh... the holes... A set of rotary elliptical cams for in flight wing geometry adjustment 😉

Are the odd holes for electrical connections? Maybe to a leading edge device.

Last Episode: Mike you're going too far This Episode: Seems that wasn't far enough

Again a nice video! But I'm also curious how Mark's airplane project is going.

New word; Horizontical. The state of being horizontal and vertical at the same time.

There are only two practical purposes possible for the small circle of holes in the Scrappy's wing spars. 1. A full compliment of 20 cal. gun barrels. 2. Air compressor lines to inflate Scrappy's wings for increased lift. Anything else is just cosmetics...GET BACK TO WORK! :)

Wing mounted electric charge ports. That way the electric bikes get charged during the flight and are ready to go when they land?

I think we just saw an "Easter Egg" . A rib at the 7:38 mark that gives some info on what this wing is going to be capable of.

Mike showing his brackets compared to Carbon Cub brackets: "Those are cute. THIS is what I need to support the 747's I plan to carry under each wing."

Mike ,you ARE this era's Kelly Johnson. Your innovative mind is bar none. Every video about this aircraft is mind blowing . The things you are doing now will trickle down and your name will be remembered for a long time to come .

Wondering if the holes are for some type of servo motors and maybe lead screws for an extendable wing? You mentioned a while back you wanted to be able to configure for high lift or low drag.or possibly adjustable twist?

It is so interesting watching Mike explain what he designs and how and why he designs it that way. His enthusiasm is infections too! As Always, May God Bless you and yours!

I'm a car guy but this is so interesting.

I am so on board with this adventure

What a wingspan! I'm stoked to finally see spars up. Attach points for a hammock in the backcountry?

Hey Mike, i am guessing that these holes will hold some electronic motor to work the front carbon slots you made as i am sure as you mentioned they will actually be retractable so you can have ultimate cruise speed and max lift when you want to land and take off. You did show hints of some of the ribs being machined with the rails machined for that, its soooo great to be able to do that and have it, ultimate mix of speed when you want it and lift when you need it. :-)

Very Cool!! Back To Work!!

Holes are for fuel lines and vents to drop tanks for the wings, ones with slots are for 2 pumps in each wing for redundancy

Your design ability and passion for what you do makes me so happy for you..... if you love what you do you never work a day in your life! Keep up the great work Mike and I'm looking forward to the next notification!!👍👍

Living the dream!! Unlimited money and time to tinker 24/7. Bet the wife doesn't complain since she married up. Haha

My wild guess is an in-flight refueling probe. Which then requires a drogue tanker setup on a supporting aircraft. My more realistic guess is for a wing-mounted camera or radar pod.

Oh man, the log to toothpick cartoon analogy is so perfect!

My bet is on a RAT (Ram Air Turbine) for emergency power for emergency power. RAT will swing down into the airstream and power whatever is needed during an IFE!

The holes are for wiring a Flux capacitor in each wing. 1.21 Gigawatts!

Knock knock. (The doorbell broke. ). MIKE’S HERE !!! DROP EVERYTHING!! Gary

Mike I'm in your head, IF, your Flaps and Ailerons were configured to both work as FLAPERONS and your Leading edge Slats were movable to the point of their trailing edges meeting the leading edge of the wing then you are creating a virtual UNDERCAMBER wing with about 30 or so more percent cord than the original wing! With an UNDERCAMBERED wing and 700+ horsepower you could probably get off the ground in the length of your plane, and when landing at SUPER SLOW Flight you Deploy the Spoilers and descend vertically to the ground with hardly any rollout, Winning every time in your class at Stol and Drag competitions! ? Get Back To WORK

The holes are mounts for poles for a shelter under the wing for camping. The wing turns into the roof of a tent. Or they are big holes to take large heat sinks for uuuuge lights.

Fat Albert has jet packs that give him stellar performance on takeoff, so maybe you are going to do the same?? Or are those going to be airshow smoke mounts??

The holes are for fuel and power ports for external fuel tanks to pump into the main tanks?

Mike as a homebuilder..A&P IA and a manufacturing engineer..and a guy who spent the last 12 years with Virgin Galactic and Blue Origin..Prior to that I manufactured the Thorpedo LSA..The first certified in the usa..as the Director of Production..I also did the first Diesel powered LSA..The holes are for an actuator..I predict..based on my expierience..Leading edge slats..Your going to tie them into some sort of angle of attack system..Like the old Helio curriers..Except yours will be automatic..possibly manual as well..based on airspeed and angle of attack. They wont slam like the old Helios..Super efficient..Much like a comercial airliner..to maximize both ends of the spectrum..Highspeed and low speed..I love your page..I have a restoration shop here in Oniell Ne and I am the airport manager as well..please stop in some time..Hope to do a stol drag here soon to..We support all forms of aviation..I fly ultralights and GA..I welcome all forms of Aviation..Hope to see you soon when you travel..

Would those spar holes at 1:56 be for an Enhanced Flight Vision System (EFVS) on one side and Doppler-capable, Fully Stabilized Color Weather Radar on the other side? And if not, why not?!?!
