It's always amazed me how such thin sheets of metal, stretched over basically nothing, can be strong enough to not be ripped and shredded by all the stresses put on it by the weather and gravity etc. when flying.
I loved "tinbash" (sheet metal) shop back in middle school grades 7 and 8. I made a very expensive toolbox as a project once. Our usual teacher was out for a couple weeks so we had a sub to supervise us - anyway, I laid out the pattern on the tinplate, cut it out, folded it up using the brake (which was REALLY difficult, it didn't want to hold a bend) and then soldered the seams (again, which was really difficult for some reason). When our teacher returned and examined our projects he looked at mine and started laughing - turns out I had picked out a sheet of stainless steel not tinplate for my project. No wonder it was so hard to work with (and expensive too!) 🤣
Andre looks much more comfortable on video now. Its cool to see these experts acclimate to being recorded and being able to explain what theyre doing in a more natural way.
There are a few great mechanics like Andre. So had the luck to have talked to and see these amazing Guru masters...builders they are just the greatest people to work with...
You are 100% right about the Sheet Metal guys doing Art. Everytime I do sheet metal at work on aircraft, I end up bleeding... it's airworthy and within spec but not as beautiful or as fast as fellers like Andre. Much respect for the work they do. Also thanks for doing this video as I enjoyed seeing the process in depth.
I was taught (in aircraft school) to never use a graphite pencil or marker on bare aluminum. It will leach into the material and initiate intercrystalline corrosion, possibly resulting in a crack. Wax is recommended. (But admittedly less accurate.)
I hadn't had an opportunity to view this when it came out, so I'm a couple of weeks late getting to it. I'm looking forward to the flight testing and post-flight review.
Well Glen I think the heat and density altitude will make for a splendid test for those new additions. Pretty soon you will have a Skyhawkenstein lol. Give us a ride when you can m8.
G, day Glen from Sydney Australia. I was going to mention galvanic corrosion, but aluminium and stainless steel is compatible. The navigation lights: LEDs for the wingtips, and who extends the wires? I would have liked some distance for V1 and KIAS before and after the wing extensions. Moreover the rate of climb, in feet per minute? 🌏🇦🇺
Are the straps an Airworthiness Directive only if you’re putting on the wing extensions? That dog over your shoulder must’ve walked half a km in circles while you were working on the vortex generators. Outstanding work! I was amazed how Andrea was directing the young lady with the rivet gun. Bucking by feel? He’s a master.
You are putting all these STCs on your aircraft which great but how do you know that they are compatible? If you have flight manual supplements for each; how do you know which set of data trumps the others? You may need an additional STC to approve the use of these STCs on the same aircraft.
The extra wing area will lower the stall speed, allow for a lower take off speed, and increase climb rate. There isn’t any loss of cruise speed. For a plane of this size, weight, and slow speed to start with you don’t lose anything you just gain.
Canadian STC at the moment, American STC shortly. Stall speed drops dramatically, no effect on cruise speed, and a negligible drop in fuel consumption.
It will be interesting to see how it flys and the takeoff and landing performance. As this wing extension is only STCd for a 172 in Canada does that limit taking the plane into the US? Also what is the wing loading per square foot now? I could not find that number in the information. Good luck with the test flight. .
I’d have to dig out more info on the wing loading - I know from our discussions during the instal, it is way over engineered with the stiffeners that we added to the main and trailing spar. US STC is hanging in mid air at this point, it was close to approval pre-covid but has been hampered by all that’s happened over the last two years. The versions for the 180 series aircraft are approved so it will happen soon. But the Canadian stc still allows my to fly into the US and pretty much all the rest of the countries we could get to.
Does the improvement in performance (climb performance for instance) allow you to raise the max take of weight on the plane? Obviously not because you just want to, but does the regulations allow that?
How much stress can these extensions handle before they are ripped away? And how much do these extensions increase the forces through the wing in total?
The wings were strengthened to handle extra forces - The plane itself will disintegrate before the extensions are "ripped away" as you say. If you are truly interested; all the testing info is available from the company that makes them (WingX) and through Transport Canada and the FAA that certified the STC.
Sir, you are made of sterner stuff than I. I don’t know that I could have watched as someone cut holes in my airplane! How much weight have these changes added?
@@GlensHangar tha is Glenn. Was curious about that. Something to consider when adding this Mod. Beautiful job. Enjoyed watching 50 years of experience installing those pieces.
The more I watch, the more I'm convinced that airplane mechanics are less mechanics and more artists. There's so much 'doing to the eye' rather than measuring the millimeter to call it mechanics.
You know a man knows what he's doing when he looks squeezes and it fits

It's a pleasure to see a man with Andrè craftmanship work, can't wait to see the first flight with all the mods
Incredible detail of the Wing Extension project. Andre is a Master Technician.
There are a few great mechanics like Andre. So had the luck to have talked to and see these amazing Guru masters...builders they are just the greatest people to work with...
I learned something today on transfering holes. :)
Glen, that was an EXCELLENT documentary of installation of the wing extension and straps. Thanks for a great job!

Andre certainly knows his stuff, amazing. Thanks.
Woo! New Hangar! Thanks Glen, always look forward to seeing you and your impressive aircraft!
Pretty sure he could do this in his sleep. Great craftsmanship.
I loved watching the dogs in the end segment.
I have been thoroughly enjoying watching the evolution of your 172, Glen!

Not André’s first rodeo eh? Man’s hand forming airfoils like it’s no big deal. I’d let him work on my airplane for sure!
One of the first videos you were pretty open about the economics of all this. Are you going to do a final cost video?
The X technique to find the hole is genius.
Than k you for sharing this video, greatly enjoyed watching the processes.
These Wingx extensions rock !!!
And that one dog towards the end in fast time never stops moving. I got tired watching lol
Waiting to hear your thoughts on how this upgrade increased your performance.
I’m beyond pleased - we’ll be talking about it all in an upcoming flying video.
Is it up? Time stamp?
Its called art.
Wow, what a lot of work!
Very interesting information, that I will hopefully never use, and even more, never need again. Thanks.
Interesting mod. Does this limit the choices for wingtips? Can you also add the dropped Hortons that add another 10” or is that overkill?
Well Glen I think the heat and density altitude will make for a splendid test for those new additions. Pretty soon you will have a Skyhawkenstein lol. Give us a ride when you can m8.
I think I saw Glen doing the math as to how long it would take to remove the adhesive from the tape off and re-polish the aluminum......lol
Andre has that cool French Canadian accent:)
I now know more about planes than my own car after watching this series... xD

OMG watch the dog in the background.. Lol.
That's Herman!
Watching this simulates what it feels like for 5 year olds trying to talk to their dad while he's working.
Asking questions is how people learn -
@@GlensHangar No, I mean the dude was basically just ignoring you half the time. 💀
Ok - yeah almost everything I said in English he ignored. I got a better response when I spoke in French.
How many holes did you have to add in the bottom of the wing to install the Spar reinforcement? 3 each wing?
I don't remember exactly - but it was probably at least a dozen rivets were drilled out and replaced for the reinforcement.
What is the purpose of wing extensions? Wouldn't the extra surface area apply more drag and lower the cruising speed of the aircraft ?
The extra wing area will lower the stall speed, allow for a lower take off speed, and increase climb rate. There isn’t any loss of cruise speed.
For a plane of this size, weight, and slow speed to start with you don’t lose anything you just gain.
Except controllability in a crosswind
Dang, all that work. This one goes on the other side. LOL 😂
You lengthened the Wing without lengthening the stabilizers? Maybe Cessna designed some extra stability on to it.
Lots of stability... pretty sure the engineers at WingX did their homework, and then proved their homework to acquire the STC.
I can see right now there's an RV -15 build in your future.
Not sure what happened in the end of video. Mine
The dog does not like to go too far from the bowl!!
Is there an STC for this? And how will this effect stall speed? Any effect on cruise speed? Fuel consumption?
Canadian STC at the moment, American STC shortly.
Stall speed drops dramatically, no effect on cruise speed, and a negligible drop in fuel consumption.

Does the improvement in performance (climb performance for instance) allow you to raise the max take of weight on the plane? Obviously not because you just want to, but does the regulations allow that?
Yes these all came with increases in max gross weight, giving me a larger useful load.
Uh... how wide is your hangar door?
Just wide enough...
Haha I'm just imagining adding 18" to each side and trying to tow it out for the first time & realizing the plane won't fit ahahaha. IMAGINE!!
How much stress can these extensions handle before they are ripped away?
And how much do these extensions increase the forces through the wing in total?

@GlensHangar thank you.
You're plane is bada$$ and I enjoy your videos! Keep it up!!
Don't Forget the Tim Horton's :)
Sir, you are made of sterner stuff than I. I don’t know that I could have watched as someone cut holes in my airplane!
How much weight have these changes added?
We ended up with a 50# increase in useful load - would have been a larger increase if we had the higher horsepower engine.
Glen what is the new wingtip to wingtip distance?
39' 8" wingtip to wingtip. Doesn't give me much room to get it in and out of the hangar.
@@GlensHangar tha is Glenn. Was curious about that. Something to consider when adding this Mod. Beautiful job. Enjoyed watching 50 years of experience installing those pieces.
The more I watch, the more I'm convinced that airplane mechanics are less mechanics and more artists. There's so much 'doing to the eye' rather than measuring the millimeter to call it mechanics.
These wing tips will give you more lift?
Yes - more lift, lower stall speed.
That high tech masking tape is expensive lol
Andre started working when he was thirteen years old to feed his dog. Tell me that doesn't choke you up.
What was the total men hours on installing the kit?
Andre can install the WingX in about 20 hours.
I wonder what that dog is smelling.
He looks like a confused fly buzzing around 🤣
I missed about half of Glen's work the first time through watching the pup.
What was the superfast section on the 3nd all about?
He put a title at the start of that section. He was installing the vortex generators.
Andre’… tu parle francais…???
Trow de horse over de fence some hay
😎🖖✌👍👌🤓
STOP BOOMERANGING WITH THE CAMERA, I’m getting motion sickness😅

Andre has an eyecrometer.
