C-17 Globemaster Build Overview - Fuselage

It's about time I actually put some time towards documenting my projects. This one is a bit late, but I hope you enjoy the mediocre build overview I've put together of my current C-17 Globemaster Project. I did my best to explain as much as I could, though, I'm sure I've left out a lot out, so If you have any questions about anything on the build, feel free to ask. Also, I have pictures of all my previous projects, so I'f you'd like a voiced over slide show of those, let the like button know.

I flew that airplane for many years. Man, you’re nailing it! Those main gear and your creative approach to the rotating-retraction problem is ingenious! You’re a helluva engineer bud.👍

[@kalvinwinder]

Thank you! I'm sure flying the real one was a hoot

[@markhuston9250]

You’re a brilliant mind attached to some very skilled hands. Fantastic!

[@kalvinwinder]

Thank you!

[@VT-FPV]

that gear design is insane! beautiful work

[@kalvinwinder]

Thanks a lot!

[@stewartkeeble2371]

Nice work on the gear sir very inventive great project 👏👍

[@kalvinwinder]

Thank you!

[@GiantScaleDave]

Absolutely brilliant, great job. Can't wait to see her finished.

[@kalvinwinder]

I appreciate it!

[@IDreadDawn]

Thats some really impressive work, especially the landing gear, wow. Great stuff excited to see future episodes

[@kalvinwinder]

Thank you! The gear were quite a process, now let’s hope they hold up 😬

[@tommyyates4639]

Spectacular work and great design!

[@kalvinwinder]

Thank you!

[@MasboyRC]

Cool project bro, this is awesome !!

[@kalvinwinder]

Thank You!

[@liquighost7988]

Randomly saw this on my front page but I'm keen to see more C-17s are one of my favourites :D

[@kalvinwinder]

Thanks for stopping by! I’ve got more coming soon. The moose is definitely one of my all time favorite aircraft and I’m thrilled to finally build one. There aren’t hardly any RC versions so it’s a special project!

[@PorscheMonster]

Awesome build video and explanation of your landing gear design!

[@kalvinwinder]

Thank you! I still feel like I didn't do it justice so if I get enough interest, I may make an entire video about the gear explaining the design process from start to finish.

[@airplanyguy68]

Awesome! The landing gear is just amazing. More videos please! The Mig-15 looks fantastic, btw.

[@kalvinwinder]

Thank you! More will certainly come. I can do one on the MIG if you’d like!

[@HMRCJETVIDEOz]

Loving the dimensional accuracy around the windscreen and nose section! reminds me of a 767

[@kalvinwinder]

Thanks! It’s still by no means perfect, but certainly a lot better than when it came off the mold. My CAD skills are lacking when it comes to replicating complex curves accurately

[@Sholto_David]

Amazing landing gear design 😮😮 Looks awesome!

[@kalvinwinder]

Thank you! It was a challenge but I think they turned out pretty good. They function on the ground, now the question is will they hold up once the plane starts flying.

[@Sholto_David]

Can't wait to find out!@@kalvinwinder

[@loebair]

looking so good! awesome!

[@kalvinwinder]

Thanks Felix! I’ve been following you and ramy for years now. I wouldn’t be where I am without your guy’s inspiration!

[@hubiactron]

Very, very cool and subscribed. I've build a c130 years ago. This C17 or a A400m could be my next project. Your retract is really awesome

[@kalvinwinder]

Thank you! The A400m is another of my favorites

[@BobloveshiscatRC]

I honestly wish I had that, beautiful

[@kalvinwinder]

Thanks sir! I wish we’d see more RC Globemasters, I’m surprised more haven’t built them. Thanks for watching

[@MikeJamesMedia]

Excellent!

[@silviaboyjoey]

mate this is so awesome, good to see a video with an up close in depth explaination on how everything works and is built, im building from scratch an a320 with 90mm edfs il be watching your videos for some tips, il probably add a video on my channel soon on my progress aswel cheers!

[@kalvinwinder]

Thanks! If you release a video on the 320 let me know, I'd love to take a look! I built an A220-300 with 80mm fans which I plan to make a video on at some point.

[@silviaboyjoey]

yeah i will let you know a soon a its up, at the moment i have got about 70% of the way through getting the molds done for all the main parts, half way through the fuselage right now , i made plugs from polystyrene blocks hot wired and sanded, alot of hours for that

[@TRSSR67]

Nice work! Subscribed and liked.

[@kalvinwinder]

Thanks!

[@Elisrc.]

Nice one👍

[@kalvinwinder]

Thank you!

[@JohnVHRC]

Awesome!

[@kalvinwinder]

Thanks John!

[@its_broome]

What an awesome project! I'm definitely interested in seeing more of this. Do you have any plans for lighting?

[@kalvinwinder]

Thank you! I’ve got part 2 about the wings coming soon. That’s one thing I forgot to mention, it will have a full lighting kit

[@russcole5685]

Nice build. Looking forward to seeing the maiden flight. Especially the wing construction is regards to Fowler flaps ect. Retract sequencing, do you use Open Tx or Edge Tx. If not, look into it. Do everything you want through the transmitter, no blue boxes needed. And Hello from New Zealand

[@kalvinwinder]

Thanks! I don’t use open or edge tx. I could program the sequencing pretty easily through my spektrum NX-10, only problem is it quickly becomes a channel hog, which is why I wanted to use sequencers if possible. Part 2 about the wings coming soon!

[@russcole5685]

@@kalvinwinder Dame, that was a fast response. Thanks man, channel numbers for add up fast. But with a simple 8ch Rx, and Sbus to a channel decoder, can easily get 16 channels. Guessing you're informed of option's available. So I won't board you. Can make set up easier is all

[@kalvinwinder]

@@russcole5685 I’ll be honest, l’ve never heard of open or edge tx until now, though it sounds like a powerful tool that could be incredibly useful so I’ll definitely look into it. Thanks for the tip!

[@russcole5685]

@@kalvinwinder you'll be very surprised. A cheap radiomaster branded radio is very powerful you'll still be able to use all of you existing radio gear as they are multiprotocol. I use a older FrSky X12S, and with a multiprotocol module in the JR bay, can use any Rx . With a FrSky module in the JR bay I can add a further 16 channels. I use this as a redundancy, sending signals on two separate protocol for piece of mind. Of if I choose can use it to expand number of channels. Giving me the possibility of 32 channels. I typically use one channel per servo. I just don't like Y leads, plus you can programme each servo to be matched or not for what purpose needed. It is a lot to program, but once done it's done. Learning the EdgeTx at first is steep, once it clicks it's very intuitive. Plenty of videos on this KZbin about the systems. Hope you enjoy, gives as much power if not more than a expensive Jeti system at a very small price.

[@mytubehkjt]

Cool model however, I'd love to see more of the Viggen standing up in the corner?..? Amazing work on the retracts too btw.

[@kalvinwinder]

Thanks so much! Since you requested, the next build vid I'll record will be about the Viggen. Though since its already fully built, it'll have to be a voiced over slideshow of all the pics I took during the build.

[@darkstar6014]

👍 greetings from italy

[@kalvinwinder]

Thanks for stopping by! Your country has the best food, I hope to visit there one day. 🛩️🛩️🛩️

[@excellenceinanimation960]

Love it man! Bween trying to build some stuff myself but i really cant do 3d modeling. Its holding me up.

[@kalvinwinder]

Thanks! The best way I’ve found to learn is to just do. It takes a bit of practice, but after a few designs you pick up little tips and tricks and it all progresses from there. If I can somehow figure it out, then anyone can

[@excellenceinanimation960]

@@kalvinwinder I'm got a couple models made. In fusion and blender. My prob is getting plans out.

[@excellenceinanimation960]

As well as modeling lol

[@kalvinwinder]

@@excellenceinanimation960 Fusion makes it really difficult to convert something into a pdf that can be printed. All my measurements had to be based off small scale screenshots, and measured and scaled accordingly since I haven't found a good way to make plans. Maybe that would be different with a paid subscription, but to my knowledge there's still some other programs you'd need to install in order to do it efficiently.

[@gareturban3558]

what resin do you use over the pink foam that doesn't melt it ? Bro this is beyond amazing work, my dream rc plane..just wow, please post updates and flights... how you wire the 4 edf's, what flight controller...everything I can't wait to see more

[@kalvinwinder]

Thank you! I use just your standard craft casting resin, it's not the most rigid resin available, but it's foam safe and perfect for my application. Nothing fancy required to run 4 edfs, just your typical setup times four. The inboard and outboard fans will run on separate batteries, that way if I lose power to one, I'll still have symmetric thrust and the plane will remain flyable. There's a lot more to come, though it may take a while since I need to make some more progress on the build before I have enough content for another video.

[@rcguy5635]

Nice work, and a great video! I was considering a C 17 build as well but the landing gear was a showstopper for me. 70 mm was my preferred size as well. Would you be interested in sharing, or selling your fusion 360 design files for the airframe and the main gear?

[@kalvinwinder]

Thank you! I am more than happy to share files, though, I would need a good website or format to share them through since there are so many parts. Also since I didn't plan to share them while I was designing it, they aren't currently very organized, so it would take a bit to sort through them and set it up in a way that makes sense. Do you know of any sites that I could upload them to for sharing? Also, one more thing, the design still isn't complete, so a few aspects would be missing if I were to share the entire fusion 360 model.

[@carloparisi3776]

Bravissimo e bellissimo, posso chiederti dove hai preso i piani costruttivi? grazie e complimenti ancora 👍🏻

[@kalvinwinder]

Thank you! All the plans I designed myself in fusion 360. Grazie! Tutti i piani che ho progettato io stesso in Fusion 360.

[@bodhescheerer1380]

Wow great work. How do you finish the printed molds?

[@kalvinwinder]

Thank you! First I reduce the print lines by sanding with 150 grit, and then 220 grit. Next if there's any impurities that need to be addressed from imperfect printing I fill and sand accordingly using spackle. As a bare minimum you can get away with putting the mold release on from here and it works if you want to save time. For a perfect mold however, I'll do 3-5 coats of filler primer, sanding in-between each layer with 320 grit. Then I'll put a coat or two of paint over that to help harden and smooth the surface. It's very time consuming, but it is rewarding when you finish and pop a perfect composite part out of the mold.

[@donbrosio]

Hi, great work. Would you share the design? I would love to print it

[@kalvinwinder]

Thank you! What aspects of the design would you be interested in? I still have all the files for the molds, hot wire templates, and landing gear, but, there is a lot of them. I'd love to be able to share them, I'm just not sure what format I would have to use in order to do that since there are so many different files.

[@tombuglewicz8020]

✈️🔧🙏🏻😮

[@edwinthomas618]

You are an engineer. You need to patent that design

[@kalvinwinder]

Haha thank you! I wish that were possible, but the design would need significantly more refinement to make it worthwhile. Also, that would limit what other people could do with it, and I would hate to restrict innovation just to protect my idea. I don't mind if other people use and improve upon it

[@edwinthomas618]

@kalvinwinder great attitude and your thoughtfulness. I cant wait to see the rest of the build. What battery capacity will you run?

[@kalvinwinder]

@@edwinthomas618 I’m currently planning to run either two 6000mah or two 8000mah 6s. One for each pair of fans

[@jeeperzcreeperzz]

Thats not proportional

[@kalvinwinder]

What aspect are you referring to?

[@jeeperzcreeperzz]

@kalvinwinder the tail in relation to the fuselage. The wings in relation to the tail. It's off all around by atleast 20% still looks OK though

[@kalvinwinder]

@@jeeperzcreeperzz It may look off from the images, but it should be a nearly perfect replica, the model was designed and scaled from exact 3-view drawings. The Globemaster has abnormally oversized flight surfaces, which is why it is so capable, and caters so well to an RC model. Though, I don't think we'll do any good by arguing about it.

[@jeeperzcreeperzz]

@@kalvinwinder fair enough. I guess we'll see how it looks when it's done.
