How it's made. Inside GCM, Vertigo F5J wing construction. 

Totally gorgeous! Way, way outside my tiny budget, but I've done a little bit of work with composites and vacuum-bagging over the years, and for anybody who's perhaps discouraged after seeing what's required to build to this very high (professional) standard, DON'T DESPAIR! It's still possible to get great results on the cheap. True, you won't have all that very light and lovely (and expensive) carbon fibre, but hot-wired foam cores and lightweight fibreglass cloth cut on the bias combined with a basic vacuum-bagging rig will still give you amazingly strong and lightweight components. It's worth spending a bit of time laying-up the wing spars (I use carbon-fibre tows, spruce strip, balsa infill and kevlar wrapping) and then vacuum-bagging everything. I made my DIY vacuum-rig from an old fridge compressor (price £0.00). The whole thing - including plastic tubing, a homemade pressure valve, bag seals, unions, etc, cost under £20.00. It's well worth the hassle because there's absolutely no substitute for vacuum-compressed epoxy-composite construction. The end results won't be as pretty, strong or light as what's on show here... but you'll be within about 10% of it; and it'll have cost something like 85% less. :-)

I bag my own wings, and every time I think about how long its going to take and how frustrated im gunna get, I actually hesitate to even get started.. I love the results but absolutely detest composite work.. You really have to spend many many hours with utter frustration before acceptable results start to show.. These wings are completely on another level.. Far above what I could do in my workshop.. I dont think id ever want to undertake a mission like this, even if I had the moulds and tooling for it... I salute anybody who does it professionally..

this makes me understand why these DLG's are so expensive! i have alot of respect for hobbiests who build these. nice video!

Chłopaki znają sie na robocie👍. Według mnie to najlepszy F5j na rynku. Brawo!!!❤

Awesome job!!! And that’s nice video because people will now understand why these gliders are so expensive...it’s a lot of work, hard work!

Another Beautiful machine will be flying soon. The attention to detail was inspiring and I hope to measure up to their standards with my build. Nice to see their application of CNC technology cutting the foam and finally doing the trimming and mounting holes. A work of Art I can hardly wait to configure and fly. Thanks for all your efforts Ali.... Nice job on the video.

I appreciate my Vertigo even more now. Thanks for posting Ali

Back in the 90’s - when I stopped competition flying - these builds were just starting. There is no doubting the performance, but what has been lost is that winter of building, and hoping to have designed a winner, ready to start the next season. Instead, it has been replaced with “the more you spend, the higher the points tally”.......

Astonishing footage, thanks for sharing Ali.

Beautiful craftmanship👍

DAAAAAAAMN! Gorgeous work!!

Well done Ali, it gives a better appreciation for what it takes to build one of these awesome sailplanes, thanks for sharing!

Amazing work. This really goes to show how much goes into making these stunning models.

Totally fascinating. Time to save up for one!

That's not modelling! That's pure art! Those polished wing moulds, magnificent. Many, many thanks for bringing this video to us. Land soft, stay safe.

Nice custom built router ! Along with ALL the hard work. Quality product!

Wow, that's a gorgeous aircraft!

Amazing!

That is just Awesome well done stunning

Amazing!!

That was cool I'm really thinking about getting in to the model airplane hobby Thanks for sharing 👍

Now that's cool as hell! Awesome video Ali

stunning

Wow it's been said before but the work involved is unbelievable I will never ever complain about the price of an F5J model again! Absolute work of art.

Gorgeous 👌👍

Very nice !

Great video and gorgeous glider

Great to see.

NOW I understand why they cost so much. Maybe if I win LOTTO or something else. Thanks so much for the great video.

Awesome! Nice video..

Good video.ty for sharing

Good work! 😉✌️👏👏

very very good job

WOW.....

As much as I enjoyed this, I think some narration, about the materials and techniques would be more interesting.

Uauuu Congratulation. Very Like Glider. Marcio from Brazil

Geil dein Airplane

It’s truely beautiful art. But, sadly, that’s why I can’t afford one. Not complaining, at least I can watch this!

1970 jack chambers builds moriah 1000 hours. And bcs rc was finally, fully proportional, he got his year and then some, daily flying. I was curious enuf to ask a million questions. I think it’s about love what you’re into. His training like the that of the guys in this vid, vip. So yes watching these guys participate in hatching this plane is awesome. I’ll take the one on one, mind blowing moments of understanding thru interaction.

Ooooooooo yeeeeeeee 🤘 ❤️❤️❤️😎

I only have one critique on your build technique: use vacuum for carbon dust. Blowing it in the air like that is a health risk and makes a mess

Nice video, what type of carbon fiber did you use ? where can I buy the same? thanks

Fun fact: 70% of the price of those F5J gliders you pay just for the paint job, lol. Stencil work is what you basically pay for, the rest does not take so much time. There are significantly cheaper F5J gliders with the same structure but without paint job, they have just plain black carbon finish and it is up to user how to paint them, but it allows to save a lot of cash.

Is there a way to learn the full wing and stab skin section schedule? What density Rohacell comprises the machined core?

I have a inexpensive balsa F5J i built in winter 3 mètres 900g A Real feather Flys the same as all these expensive carbon gliders It s the INSIDE F5J

Dear Flight Comp Do you give any advice on a F5J Sailplane? Or Calling be Better? Explore 3 3.8 m Thanks so much.

Gorgeous!!! Sooo I guess people aren't using feathercut any longer? :p

How to make hinge on composite aileron?

How long would the build be if you just didn't do any graphics?

Прекрасное видео о том, как наносить рекламу на свою продукцию и о том, как вырезать отверстия на ЧПУ-станке 😂

Clearly extraordinary work but without any exposition it is of minimal value to me.

How's the radio interference with all the carbon?

Amazing work , but still $1500. that"s a lot of money

Where are these Gliders made?

Jesus christ stop moving the camera, I'm here to see how it's built, not to throw up

Kameraman hat keine ahnung!!

Get rid of the annoying music and add some commentary about the process .
