@@MikePatey I don't know if you will see this, but I recently found and purchased the plane my father built in 1978. I was fortunate to have use of this plane as a kid. It's still flying, but (42years later) in need of repair. I was hoping you could tell me where I can find information on working with fibreglass and carbon fiber. KZbin videos are always lacking critical info. This would mean a lot to me. Thanks, Jay

EXACTLY what i was thinking........warp drive....??

[@marinetothecorps4864]

“Never been done on an aircraft however, it has been flight tested” ... morning coffee through the nose on that one Mike. 😂👍

[@portnuefflyer]

"One, to two thousands, I'm not holding it together, it fits that tight." For this half a** pipe fitter and pilot, I'm in awe! He has access to the best of the best in tooling, and even better, knows how to use it, and EVEN BETTER, it's all aircraft related. Carry on.

[@StephanLiebenberg]

I was just thinking about the drag that gear would create. Then you mentioned that tidbit in the end and I immediately went 'well obviously!' You really think of everything

[@warrendemars]

All of those tubes will add a significant amount of drag, well, 35" tires aren't exactly slender, so might as well make the fairing wing shaped to help negate some of the drag and add lift.

[@tomcoryell]

I was thinking weight would be an issue as well. This is going to be a really interesting build and finished plane!

[@danieldimitri6133]

If you want to avoid the tires from scrubbing you could have the camber change to your advantage. If the suspension were going beyond parallel to the ground on compression you could use a shorter upper arm. So as the arms swing and bring the width between the spindles down it gets negative camber in both extention and compression beyond when the arms are parallel to the ground. You could build the spindles with a little positive camber so they average closer to zero. But if the arms parallel to the ground is the extent of the travel you could make the spindle height a little less than the height between arms at the airframe. This is kinda opposite of a lot of racing vehicles since they want negative camber to adjusfor body roll and tire roll but for landing purposes I think it makes sense. I might also be inclined to cris cross the lower arms to maximize the scrub radius. Now all I need to do is learn to fly and make a few million dollars so I can test it 😁

[@scybolt]

That's what I was thinking too. Tricky though - because to truly avoid tire scrub the wheel alignment would need to change as a function of the change in the landing wheel's horizontal movement over the change in tire rotation speed - not just the landing gear's vertical compression - though I'm sure taking advantage of camber change would help some.

[@thewoodshoppe1008]

Ever since I found your videos of Draco I've been hooked. I'm not a pilot however you explain things so simple that I actually understand what you are doing and it's fascinating to be apart of the build process of Scrappy, so I thank you for taking the time to make these videos for us.

I remember a long time back somebody made a three wheel streamlined car with a motorcycle engine that was supposed to get high gas mileage but no one bothered about tire alignment. It steered badly, the tires wore out, and you couldn't fix it because the basic design was too weak and nonadjustable. It sure was shiny though. There is no replacement for doing your homework.

[@joelbosshoss9029]

Mike. Nothing you do is boring. You remind me of someone I admired immensely in the early 80's. He worked at Skunk Works in Southern CA. I was friends with his son and dated his daughter. He would bring blue prints home, yes actual 1 to 1 size, to study. He ask one time if we could tell what we were looking at. Of course we had no clue but one time it was the blue prints to the tail section of the f22. He would wake up at night jot something down on his notepad he kept and we would help build what ever he drew from tractors to go carts. He has since passed from working with all the exotic materials and not wearing respirators. Anyway long story short put a sock on your hand while feeling for imperfections on any surface. You will feel the tiniest of imperfections. It's the little things that make a big difference. Thanks for the awesome vids.

ADHD is often described as "feeling as if you're driven by a motor--like having a race car engine with no brakes." I'll tell you, it often feels manic/compulsive. Once I started taking medicine (Concerta) at 42yrs old, I was FINALLY able to harness and direct that feeling. My productivity level went through the roof! Not sure if Mike takes medicine or not, but he's clearly got a handle on focusing the "God-given gift" that is ADHD.

The engineering that went into the jig itself is mind blowing let alone the A arms and knuckles. I wondered about toe in and you explained it good. An other question I have how are you protecting the inside surfaces of the welded components?

How are you protecting the interior of your components or is it not a worry ? As always Mike your amazing.

Please please please do a few videos of just your solid works. It’s not boring. You’re helping out the GA community.

[@DillysADV]

Where your tire stays vertical through the entire range of motion, you'll still create scrub as it travels. Why would you not do similar to the automotive application by shortening the upper arm to give the wheel some negative camber at full extension? That would allow you to "preload" the suspension easier before take-off to give you that spring effect like you were doing with Draco? I am guessing to help with the stresses?

[@Skinflaps_Meatslapper]

It appears that the UCA and LCA attach points are not parallel to vertical, this would give a small amount of unequal length. It's likely just fine for the type of suspension this is, though it doesn't leave much room in that regard for non-level/single wheel landings. Most of the reason you see unequal length in vehicles is due to steering concerns (bump steer) and in applications where tiny adjustments in suspension geometry make a huge difference (race/ high speed).

Hey Mike, are you planning to heat treat the arms? Welding will leave the joints in an annealed state so hopefully you accounted for that with your stress analysis. Edit for spelling and one more question: did you build any camber gain into the geometry? With car suspension it's really important, but I would imagine body roll on an airplane is less of a factor. Love your work, just always want to know more about the thought process that goes into a design.

You raise a great question - it seems to me that body roll resistance might be a good thing (check out the videos of Draco, and especially the crash). Anybody ever see an airplane with an anti-roll bar in the suspension? 😜

I wonder if there was some effort to slow the cooling of the welds, especially where the spindle attaches to the upright?

[@Mrfishlou]

@@dennyo3992 In general, as steel comes down through transition temp, the slower it cools the more chance it has to anneal. If cooled quickly enough, it will retain hardness. Chrome/moly is pretty hardenable, and as carbon content goes up (ie, 4130 vs. 4140 vs. 4150) the harder it will be if quenched (cooled quickly) - but if the quench it too severe it can crack. My recollection for the large pieces I used to be involved with is that 4140 required significant pre-heat, and controlled cooling with ceramic wool blankets, to prevent hardening and cracking. I don't think that would be as much of an issue with those small TIG welds, but don't know for sure. Depending on the filler he's using, it may match up with the desired hardness of the tube just by air cooling without any post heat or blankets. I would assume Mike has this well thought out, since the results he had on Draco looked to have turned out tremendously strong (did any welds fail on that Horrible Terrible No-Good Very Bad Day?).

Matt Uecker thanks so much, I appreciate the information, I’m not an engineer or a pro welder, and am always interested in what guides designers/engineers decisions.

Best channel on YT. Trent Palmer brought me here and I don’t even watch his stuff anymore. Engineering and fabrication soothes me.

[@kevinbowers3917]

Kudos on those dimes,, stacked like a full time welder..Cheers,ed.

[@MrRBobs]

let me tell you Mike im no spring chicken but 15 mins in and you've just solved a riddle iv pondered on for quite some time, really enjoying your build fascinating to see the one of a kind craft take shape and the engineering involved thanks.

[@Zalex612]

Mike: I'M SO EXCITED! Me: ME TOO! Also me: Insta-like!

[@Ludovick.Dostie]

Is there anything you can’t do? Crazy to see how involved you get in every aspect of the build! Machining, welding, engineering, body work! That’s just fantastic!! Can’t wait to see the final result

7:31 Mike, "When we put it together, it actually pinches it." Me: "@:-O" (Mind Blown)

[@lightespeed]

Love to see, even though Mike has had decades of engineering experience, he is still so obviously excited by precision & accuracy, the satisfaction from achieving those levels is hard to beat. This is an orgy of accuracy and precision.
