When Mike Patey started scrappy i was really excited and couldnt wait for the next video BUT THIS, THIS is the build I wanna see!!!! I really cant wait for the next video Greg, so looking forward to this build!!!!!
I don't know that I'm a perfectionist but I hear you. I rarely do work that I'm really happy with. I always see something that I could do better if I had the chance. People tell me how great something I did looks and I'd always think, "are we looking at the same thing?" But I've come to terms with it. If the customer is happy with it, it must be good. When the customer is me, then we run into problems like you have there.
From Alaska, thank you for taking the time to put this content on UA-cam. I have a 160hp PA-12 with extended wings and flaps, I would love to hear your opinion on it once you fly this.
I will say it was not on my list, in fact I really was not researching 4 place airplanes to build. I like my Cub a lot and thought if I could combine what I like about the cub in a big Cub that had space I would probably have the Cub I need. I decided on the 4 place cub because I know three people that I respect that say it is the ultimate bush plane. The other reason is, I know if it is not what I want when I am done it will sell fast for a decent profit.
@@cptinsano43 if you mean the 4 place bearhawk... It's basically a heavier version of bushwhacker, it's very much like a maul. I'm guessing it would be a been there done that deal.
There's no such thing as being too much of a perfectionist Greg. YOU have always done and will always do perfect work! Thanks for sharing with all of us. Looking forward to following you through the build.
I knew it! I said when you showed how you built BW 2.0 it seemed like you were trying to make it like a 4 place Super Cub. You are friends with Kirk Ellis...it just made sense you'd go 4 place Super Cub. I've watched all the Airframes Alaska videos with Kirk and his...amazing how well they perform. What engine are you going with? Looking forward to watching your build! Great chance...I've seen the finished product, but never seen you in action.
The 4 place Super Cub is my dream build. 🤤 Having never built an airplane, my concern for a first timer would be the complexity of bringing together parts from several sources. Of course, there are many great resources, but I wonder if a full kit wouldn’t be better for a rookie? I look forward to watching this one come together Greg!
Can’t be happier to see a new and (hopefully) detailed build series. I was super exited about Pateys Scrappy build, until It turned into a OCC Chopper-build😁 I am working on my second experimental Super Stinson 108 while flying the other one, great with some inspiration👍🙏
Another modification we are looking at is putting the front seats on Cessna rails for getting in and out easier. The doors are huge but the rise in the angle makes it hard for a guy with a bad back to get in and out.
@@mauleguy yes the right seat is adjustable. It is easy to adjust or remove, but not from a sitting position. (The left seat is fixed) The back seats are completely removable. Carbon Concepts did a great job making them with a storage compartment. (Right Front & rear seats removed weigh 32lbs)
Wondering what this plane will do that Bushwacker won't? I don't understand the reason for a 4 place cub. It seems to me that the cubs narrow fuselage was one of it's most unique strengths. Excited to follow your build.
I know a few guides outfitters using the 4 place and they all say it will pretty much do anything a narrow body will do. If you want to go into that short tight strip keep it light and it will perform right along side of the narrow body cub. If you want to load it up it will preform better than a narrow body cub of equal load. It has better visibility landing then a narrow body cub. I guess we will see when I am done whether it was the right move. It actually has more room inside the cockpit than a Maule by the looks of it. Definitely wider!
Very glad to see this build, with your experience on the Maule and your Cub you already know where and how you want things. Kirks four-place has always been one of my favorites and I'm very much excited to see your take on it. Was sad to see Bushwacker go but I'm betting you will make this one better in all ways.
where do you find plans for a supercub or is this a copy of a factory made ? I was gonna TIG my frames but I got a cobra torch to gas weld them instead. they weld 4150 pipe with shielded flux core MIG but I don't see anyone doing frames like this, it would be a lot faster.
I feel your pain with tig. Sometimes i do really well other times Meh. I'm pretty good with oxy acetlene welding though and sometimes when tig just gets to frustrating I go back to the torch.
I'm looking forward to watching you build your next project. I'm interested to see how your build differs from a "stock" Super Cub'. Thanks for continuing to post videos. I had started a stretched Pacer project 25 years ago but realized that I had other priorities (young family, limited income)
Neat project! Look forward to updates. Sounds like there are a few YT videos left for ya huh? I mostly gave up making videos years ago because of the time suck. Grateful to watch yours and others. I have a set of Bearhawk 5 plans I am reviewing. Who wants to fly smokers anymore? Need a personal airliner.
Unrelated to cheap terminology because they have always made the builds junk in the past, I think your magnifying glass to see the welds up close makes sence! I thought, how the hecks are the welds so clean? Makes sence!
Hope to see more fabrication and building. After a while a lot of those remote landing sites start to look the same. I'm sure they don't to you though.
I don't understand why guy love powder coating fuses. It cracks and allows moisture to hide unseen under the cracked coat on bare metal... Why do you like it?
Sounds like you have your mind made up. Powder coating may not be as good as epoxy prime and top coat but it is better for my health. I like how it gets into all the hard places to get paint to flow into. I have seen parts that were painted start to rust in the hard to get to places and that makes it just as hard to see a crack too. I will continue using it until I see a serious problem. I have restored 1 and built 5 airplanes all with powder coating. Having the problem of peeling, cracking is not something I have seen.
saw highlander build and builder had his fittings powder coated also oratex fabric oshkosh explain there fabric is safe havent seen any oratex aircraft Alaska
@@jeffpine3036 oratex is awesome. It's rediculously tough and holds paint beautifully. The biggest challenge with it is you can't be sloppy. Lots of ugly o-tex jobs out there.
It's surprising that the maker of the fuselage doesn't put this baggage door in, seems like it's been an absolute for bush operations, even general use for a long time. Don't these manufactures go out and seek the opinions and suggestions of top bush operators, Hell just even paying attention would go along way. to seeing what the market wants.
Airframes would probably do the baggage door but the 4 place Airframe is actually “Certified” and they can’t modify anything from the original. If you build it up “Experimental” you can make modifications like Kirk did on my 4 place 896AK and Greg is doing now. The guides in AK have to use the certified version for insurance reasons. You cannot operate for hire with an experimental.
@@quadcub1223 You are correct! Airframes at this point in time will NOT make any modifications to the fuselage even if you are willing to pay. It does make sense. Every time you make a modification you slow the production process also they would have to do engineering if they were going to put their name on it. I am very happy with their product.
@@mauleguy Greg you’re welcome to come to Utah and fly our 4 place that Kirk built. (896AK from the video) Several modifications we are thinking about that you might want to look at.
Funny how I mentioned the 4 pl cub from Airframe Alaska as a potential replacement for your Maule and I asked your opinion but you did not answered. I knew you were up to no good anyway. I used to Tig weld for Mc Donnell Douglas at the Long Beach plant in the 80ies. I worked on the the C17 cargo plane. I was very good at it but they treated ne like shit because I am French and was not yet American I used to walk around with a fucking badge that said alien on my shirt. I quit and opened my own business. You should have had Airframe Alaska make the mods for you. If had your budget, I would get the whole frame stress relieved and tempered back to the original 4130 numbers. Especially with the kind of flying you do. With Tig welding you lost 30% of chrome molly original impact and tensile properties. Powder coating is crap it peels off and fractures a lot with vibrations. Does not have the paint elasticity. I wont say anything about Airframe Alaska welders. The few videos where I could see the welds did not impressed me. I would pay an inspection company to run some UT scans on the most critical joints. Tig is notorious for poor root penetration. Ironically Oxy Acetylene is much better. Hope to meet with you one day. Bernard
I have seen a lot of tig welds over the years and theirs very nice as far as I am concerned. Maule mig welds their fuselage and it looks terrible in comparison. I have never seen a fuselage fail from normal use or really even from abuse. I use to be part of the process on landing gear production for a company here in the Pacific NW. I did machine work for several different weldments that went on different aircraft landing gear. I coped the tubes and made lots of different fittings. The company I did the work for always sent their product out for normalization. It was required as far as they were concerned. I use to do my own landing gear for my Maule and I did send it out for normalization the first few sets. Then I noticed no one else did and have not since. Never had a gear fail at a weld of around a weld. I have broken an axle but that was my own fault and not at the weld. Powder coating may not be as good as epoxy prime and top coat but it is better for my health. I like how it gets into all the hard places to get paint to flow into. I have seen parts that were painted start to rust in the hard to get to places and that makes it just as hard to see a crack. As for UT scans I am not worried, But if you ever get a chance to go for a ride with me, you are going to be saying to yourself Greg built this contraption I hope it holds together:))
@@mauleguy Because you never crashed hard. there is a unique elasticity in 4130 that is severely reduced post welding. If one day the dashboard meets your ribcage, this might elicit a sense of regret. I was not referring to weld failure during normal use which is linked to metal fatigue at the HAZ Why do you think they heat treat frames in formula 1 racing ? Lastly pretty welds dont mean shit. Takes a long time to evaluate visual quality, it is part of welding inspector training and experience. I just bought an old French lathe and all my cuts look bad. my buddy down the street is a professional with the same exact machine, and his parts are like chrome. I wonder why
@@bernardmauge8613 Not totally true, I crashed pretty hard that one time. Even the Maule mig welds did not fail. Lots of tubes buckled and bent, but everything was still attached when all was dead quiet! ua-cam.com/video/J2i58RhbA98/v-deo.html. The only tubes that did break: one was the rear spar carry through and the other were the windscreen V brace. The rear spar carry through did break at a cluster in the center but that was where all the pressure would have been because of the leverage of the force on the wings. I repaired that fuselage and even though it looked pretty bad in the pictures once I cut the bent tubes out the structure returned to it's original shape. You can see my jig I built in the video to restore the fuselage. Airplanes are built to be light and strong but unlike a trophy truck they are not built to crash. I still believe there is some crash safety with a 4130 fuselage if you never stop flying the airplane and slow it down you will survive.
Weren't the old original tube and fabric airplanes like T crafts and cubs etc. oxy acetylene welded? I always thought Tig was said to be stronger than gas or especially mig, but I'm no expert.
@@mauleguy Good for you. You are also wearing a helmet which is of huge advantage in a crash. I never understood why airplanes do not use doors for protection against buckling like cars do. You have the mass of the engine pushed into the cockpit and nothing side ways to prevent deformation except the roof may be. One would think installing longitudinal bracing in the doors should be mandatory especially in sports category. Be well.
I'm now a retired professional Weldor / Fabricator, most of the places I ever worked required double eye protection when using any type of power tools especially an unguarded cut off wheel. An eye injury might make a huge difference in a Pilot's world.
Good point, don't do as I do.
Double eye protection is overkill for most things. Give me a break.
Really respect you as a pilot and person love your videos. I no nothing about flying but you explain it so I can can enjoy them
When Mike Patey started scrappy i was really excited and couldnt wait for the next video BUT THIS, THIS is the build I wanna see!!!! I really cant wait for the next video Greg, so looking forward to this build!!!!!

Curious on your take of the 4 place Bearhawk, and why it didn’t make the cut in your decision. Looking forward to following along!

Exciting man. Thanks for sharing this journey
A four place cub has been my dream plane since I got to fly in the original. Excited to see how yours turns out.
Can't wait to watch the build! Stumbled on you channel this afternoon
I love the intro. No crappy music - just pure awesomeness
Thanks for continuing the videos. I’ll enjoy the build videos just as much as your flying videos.
Might be following you down this rabbit hole. Been sitting in the bleachers for long enough.
A new project !! cant wait!

Looking forward to your build. Saw you’re using Javron wings. Did you look at all at the Javron 4 place instead of the Alaska Airframes 4 place?
Sweet!! Thanks for posting! I look forward to the next 😁
Awesome! Looking forward to watching this build come together.
I’m excited for you Greg! Now you can haul your family and gear in one trip. I love a cub!!

Really enjoy some fabrication videos, it'll be a great project.

Probably two winters, this being the first:))
Unrelated to cheap terminology because they have always made the builds junk in the past, I think your magnifying glass to see the welds up close makes sence! I thought, how the hecks are the welds so clean? Makes sence!
Can you post the bare fuselage weight before you start adding panels. I'm curious how much lighter it is compared to my bare m6 fuselage.
Yes, just ordered a scale to weight things by hanging them.
Looking forward to your new project, what’s going to power it?
lycoming O-360 most likely A1A
Hope to see more fabrication and building. After a while a lot of those remote landing sites start to look the same. I'm sure they don't to you though.
the quarter turn fasteners are commonly called camlocks nice work mike
Well they maybe but that just happens to be a name brand of 1/4 turn.
Hmm, my Pa always called them Dzus fasteners.
I think that was the guys name that invented them "Dzus"
Curious about whether or not you will go with the single center front seat like the Maule it more or less sat just like a cub ?
To cool. congrats and happy new year to you and yours
very good
That’s gonna be so sweet! Keep posting the vids
Excited to watch your build. Hit me up and I'll get you our metal or plastic Landshorter VGs.
Awesome project!
Projeto incrível!!!
can airframes change angle of incidence or does builder?
Only the builder can do it, they will deliver a certified fuselage in the 4 place with no changes.
That’s one thing I didn’t like about the maule were the doors, when I had my Stinson I thought the doors were better than my neighbors maule
Are you going to change your name from mauleguy to super cub guy? Looking forward to following you on your build.
