Welcome Everyone! This video was tough to piece together... As you know I'm in Canada, and Canada has two official languages English and Québécois French. The crew that came in to instal the STOL kit and the WingX extensions (that's the next video) were from Québec and a couple of them only spoke French, in the video Andre peaks English but he wasn't comfortable on camera speaking it. I speak French, but I'm not comfortable on camera speaking French.
So the video might seem like a bit of a jumble.
Off camera we spoke Franglish and we were all comfortable in that uniquely Canadian language.
Hi! This is awesome! I fly a Franklin powered 1959 Cessna 175 Skylark with wing extensions in Switzerland. My first landings after installation were always a bit long because it glides better. I feel like the climb has improved too, which helps when getting to our high IFR altitudes in Europe in a cruise climb without cooking the engine at Vy. On the other hand, hangar space is tight now! Keep it up! :)
As a retired McDonnell Douglas Lab Machinist, I am enjoying this channel as well as the food channel. Working with talented craftsmen, such as Andre is refreshing to see. Please continue!
I admire your technical and commonsense approach to this whole project Glen.
I've really loved doing this project.
@@GlensHangar
It shows… and that makes it enjoyable for us!
It's always nice to see a true craftsman that truly knows what they are doing and do the best possible job.
I like how serious Glen is about his airplane. No room for over pouring.
Glen, I have been enjoying this series more than you can imagine. While most builds on tv and UA-cam are beyond the average person this is a project that is within my reach which makes it so much more fun to watch.
Put on many STOL kits in my younger days. Use to fly and worked for Owl STOL Aircraft out of Fort Worth, Tx.
despite the fact that I know diddly squat about planes, this has been a fun learning experience
Glen this is such a great Series.I can’t wait to see her in the air.
I worked for Wren Aircraft in Buckeye, AZ back in 1986. We modified the C182 into the Wren 460P STOL. It was a complete STOL modification that went way beyond the leading edge cuff.
Those were amazing - we did as much as we could with this 172: Sportsman STOL cuff, VGs, 3 feet of wing extension, and the drooped wing tips. If only we could have put canards on the nose...
Glen, I really enjoy watching all your videos. Whether it’s about flying, cooking, or cocktails. All the great things in life.
Interesting installation. Am glad you make these videos to show us how things are properly done. I will be looking for the next installment to see it finished. I also want to see what the difference in performance is.
Us sheet metal workers from the USA would call the formed edge that Andre put on the leading edge, a "Hug Edge".
You’ll love the VGs ! Been putting them on planes for years.
Elevator authority will be very light to the touch 😎
This is a great addition! We love our STOL kit!
Most helpful! Picked up some new techniques.
G,day Glen from Sydney Australia.
Wow......
Fantastic filming: thanking you for a look at airframe engineering.
It would have been interesting to attach tuffs before the modification. Then again after the mods. Just to see the airflow variations.
Fly safe: blue skies

Can you comment a little more about the VGs? How do those little tabs make that much of a difference? Thanks! I’m glad you added this channel it’s really wonderful
In upcoming videos I'll try to explain it better -
Andre needs to go oh no! Every once in a while to keep Glen on his toes LOL 😆
Been watching your videos. You are doing a lot of the same mods I plan on doing with my new to me 1956 172.
I really like your project very interesting, I am not a pilot, but there are some in my family. keep up the great work, I am sure this costing a lot of $$$$, but this vintage plane is so cool thanks for sharing, Love the old-time cooking show too...
I've always wondered what one of the relatively simple Cessna's from this family would do with some performance upgrades in the other direction, full gap seals on all control surfaces, more modern cowl design, variable pitch or constant speed prop, and some attention paid to drag from where parts of the body meet (struts connection to wing and fuselage, wing to fuselage, tail surfaces to body).
Obviously you're not going to change the Vne or Vno to that of a Mooney but I bet you'd get a decent increase in cruise speed at 75% power or some useable range.
Glen, could you do an explainer as to how these wing extensions affect performance? Or what they actually achieve? In a more technical manner. - Loving this series! I'll never be able to fly (medically) so this is sort of a vicarious thing for me :)
When we get everything installed I'll be running through what they do.
Yay! A new Hangar!
Huh? Same mechanic's hangar...
Small changes to wing profiles make big changes. Your profile change is actually huge. It will feel like a different aircraft.
Take off and landing characteristics changed completely - still getting used to it.
Thanks, Glen I really enjoyed this vid😎
Great episode. Can you detail the benefits of this new ‘kit’ on the basic aircraft performance? I flew the standard 185 and a Robertson STOL 185 and the low speed handling of the kitted aircraft were quite different.
I remember back in the 60’s in Guelph seeing this aircraft stop by for gas.
Great show(s).
Glen, I look forward to seeing the following videos. As to comfort on camera, that's hard, but Andre came off just fine. How far behind are these videos? In other words, I am going to assume this work is already done and you've been out flying already. Are you seeing any penalties in the top end, or maybe it's improved? I really have enjoyed watching the transformation of this old 172 into what she is now, and what she will become.
looking very nice!
Very interesting to learn
Hey Glen, looking forward to your opinion if the extensions really make that much of a difference in flight. 172s fly great as is so this will be something if the difference is big.
ps, this will open up more grass and asphalt strips for you and Julie's adventures. ;p)
I was worried about in flight changes - as we started doing the mods I definitely worried if I was going to mess up a plane that flew straight and hands off. But after flying it on a couple cross country jaunts already, It still flies straight / hands off.
The big change is how well it now handles at very slow speeds, takes off with a shorter roll, and lands slow and short.
Just found your channel. I’m really enjoying it. I own a 172A. I was wondering if you have the 0-300? Thx
love it great work
its already a stoll aircraft, they are so light. i put flap gap seals on my old 172C, half fuel and me 80kg, the airspeed indicater doesent read the stall speed on landing, had to be under 40kts, my guess about 35kts. this one has to be way better. my stall speed was lower than most micro lights
New sub ! Liked 😀❤️🙏
What are those "clicows"? One of the Chicken Wings comics has Chuck working on his beloved Corsair's wing with them...
They are temporary fasteners that hold everything together while you line up the holes before you rivet.
I'm curious, what sort of landing/take-off improvements do you expect from the STOL kit and the VGs?
I was expecting stall speeds to be at least 10 MPH lower - stay tuned for the results.
@@GlensHangar Very nice.
I live in Ottawa/Gatineau - its not uncommon to hear "Franglish" like "Comment dit tu 'sparkplug' en Englais?" 🤣
I’m curious how the increased camber and length of the wing will affect cruise speed. Given that the 172 isn’t exactly speedy to begin with, I would be reluctant to sacrifice even a couple of knots.
I was worried too - but there's no need to worry.
The next step is to install the kit for JATO
Scram jet is probably for later...
A C172 has a NACA 2412 airfoil. It has a Cl Max of 1.5 at 15 degrees AoA.
What exactly have you added to your wing ? I wouldn't mount anything to my wing until I saw L/D polars for it.
Do you have the extended front forks and the longer prop?
will the new seam at the junction of the new wing cuff be water tight? if not, how will you inspect for possible corrosion?
It will be as water tight as any other part on the aircraft... which is to say; not very watertight at all. Cessna seems to follow the 'Let water flow out as easily as it flows in' design philosophy.
Thanks so much for filming this! We just got done installing a Sportsman STOL kit on a 182-B, and it was an excellent learning process. If you have video of Andre using a straightedge to check the alignment of the foam blocks, could you share that as well? It turned out we were doing it incorrectly (as the instructions weren't super descriptive in that area), but fortunately we figured it out at the 11th hour.
Also, did Andre lay down a bead of sealant across the top rivet line (but not the bottom rivet line), in addition to the front face of each foam block? We had some debate as to if this was really beneficial, but ended up doing it as the instructions called for it. Just curious to find out more from someone who appears to have done plenty of these kits.
Also, does the 172 kit come with aileron gap seals like the one for our 182?
Andre didn't put the sealant on - he's seen several of these kits taken off after years of use, and his opinion about the sealant is that it breaks down over time and with flexing stress of the airframe. The gap seals for the ailerons are part of this kit and we put those on; but there was a discussion about their usefulness.
Very neat to see the profile change.
Will there be specific procedures and adjustments to the AOA sensor and your Airspeed indicator etc now that Stall speed is lower? Does that kit come with a set of numbers of what will change or do you figure out that yourself on the flight test?
We definitely have to re-calibrate the AOA, and we have to figure out all the numbers ourselves since we stacked 3 different STOL kits at once.
I think I've seen a 172 with a stol kit about 25 years ago in the Kimberly here in Australia. Please excuse my ignorance but Just out of curiosity, is there any corrosion protection uses at all with the install?
"the video might seem like a bit of a jumble." lol much more then a "bit" but overall an informative vid,
Curious to know how MVU fly with the cuffs and VG's. I'm sure it will be more stable and responsive, but will cruise speed or economy suffer?
What is the cost of this project being done?
Did you have to recalibrate the AOA with the new wing shape?
Yes - Recalibrated for each flap setting, and a couple different weights.
will the wing stall at the root first like the factory wing ?
The stall is as docile as the factory wing - maybe even more docile. Full flaps the stall is 25 mph, with the STOL kit, VG's, and the WingX wing extensions: ua-cam.com/video/UgUwqIUqZDw/v-deo.html
Wondering how much cruise speed you are going to loose ?

No reduction in max / cruise speed - in the next episode we instal the WingX extensions and that saw a 1-2 MPH increase in initial testing... of course that's within margin of error territory. So no appreciable difference in max / cruise speeds.
It’s like having permanent slats - does it reduce max speed?

@@GlensHangar Ohh nice! Forgot you were doing the tip extensions. Guess it’s an overall net decrease in drag. Very cool.
