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

[@EleanorPeterson]

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. :-)

[@MoritzWeller]

That sounds great! Do you share your builds and experience anywhere online? Looking into scratch building myself. Besides doing RC conversions and flying bought models.

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!!!❤

[@petrokemikal]

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..

[@GWAIHIRKV]

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”.......

[@XFBO]

You nailed it! Id say 40% of the joy brought in from this hobby was building your own over the winter break....I STILL have a few foam cut wings as spares from 20 yrs ago!! Lol I loved pressing my own wings with obechi veneer..... does anyone even do that any longer?

[@tonyrusi1978]

Kitesurfing, Hang Gliding, and Sailplanes could all be revolutionized by building a wing like this, just scaled four times bigger in all dimensions.

[@flightcomp]

I still build, almost every day. Balsa, built up. Still love it. I spent my entire youth building built up TD and power planes.

[@summoningdark216]

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.

[@keen2b]

Now everyone can see what goes into making this wonderful glider worth every penny!!👍🇬🇧

[@Mytyweav]

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.

[@kenspaceman3938]

Beautiful craftmanship👍

[@ArthurRC]

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!

[@XFBO]

Agreed! But half the fun of flying when i used to do it 20+ yrs ago was cutting your own foam profile and covering them by press or vacuum bagging..... I've been out of the hobby for a long time but if homebuilders have to compete against THAT thing.... it's kinda unfair imho.

[@simonl7784]

@@XFBO This IS what home building looks like now. The molds he uses are industrial grade and have to be machined professionally but once you have those, the materials, tools and techniques can all be learned online. May I suggest you look up a this youtuber: kzbin.info: Ramy even 3d prints his molds and gets similar results.

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.

[@JoshWeaverRC]

I will. I don't even want to know the price if it took a week to make.

[@peterzingler6221]

@@JoshWeaverRC around 2k with 600 to 800 bucks for the used carbon fiber alone

[@illla]

And that foam core wings model is not even the most expensive J glider. High end gliders use carbon fiber+balsa skin and ribs structure for the wings, but this is significantly more expensive structure and more labor consuming process than foam core gliders. Most composite gliders manufacturers use foam core technology just because of it is relatively cheap and simple.

[@sseim5654]

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

[@yeahitworks]

Great video and gorgeous glider

[@valderja]

[@garryperrin2408]

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.

[@simonl7784]

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

[@johnw5154]

[@michaelwhinnery164]

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

[@EleanorPeterson]

Hi, Michael! Sorry, but I think you'll find that alchemists hate to give away their secrets... ;-) I make cheapo composite gliders with homemade equipment, and you can get really good results by using fibreglass cloth instead of carbon, and laying-up spars from balsa and inexpensive carbon-fibre roving (tow). It's messy and can be frustrating, but I think a lot of the magic comes down to practice and patience. The end results are excellent. Metal moulds are strictly professional, but a basic vacuum-bagging setup needn't cost more than £20.00.

[@davidmiller4594]

How's the radio interference with all the carbon?

[@flightcomp]

It's not bad, but the antennas must be outside of the fuselage and carefully positioned.

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.
