Informative. .... now if I could just stop these seizures lol

Apologies for those 😅

Briiliant Alex, thanks for sharing. I like the details you've included. The headcam is great IMHO, the audio is spot-on. Your apprentice is switched-on too. That perforator tool is something I reckon I'll use. I'm building a 6M ASH 31.

@AJHewson1 3 года назад

Thanks for the feedback. Wishing you great success with the ASH 😁

Can you do a video about your DIY refrigerator pump setup? It looks very cool!

@AJHewson1 2 года назад

I can try do that. The controller was done by a friend of mine

Beautifull video, great visual content to learn to make this beautifull wings. Can see that there are a lot of hours and trys behind this clean and beauty work. I'm building a 4m astir scale glider, i have now the foam cores and going to fiberglassing this wings with the best of my😅😅. Thank you to teach us a lot with this beautifull video!

Great work! Any tips on ensuring your wing is strong enough (weave and unidirectional) without resorting to trial and crash?

@AJHewson1 11 дней назад

@@coreybennett564 good question. That’s a very hard one to answer without trial and error. I’ve got the luxury of many wings made to gather data from. My recommendation would be to find someone who has made similar wing to what you plan and ask their layup

@Allibow 2 года назад

Love it! I have bagged som dlg wings myself so satisfying!

@lyallm331 2 года назад

Awesome how-to video 👍 As a fellow kiwi I'm wondering where you buy the high density foam from for the cores? I can only find beaded polystyrene in the hardware/building stores. Cheers

@AJHewson1 2 года назад

I get it from specialty insulation places. Composite-nz etc

Hi Alex. I am making a wing in two halves like this with a shear web spar caps. How should I join the wings? Is it worth the trouble of finding a way to make the spar go across both?

@AJHewson1 2 года назад

Send me an email to alex.james.hewson(at)gmail.com and We can brainstorm a good solution together 🙂

@RCjunkie 2 года назад

There is a tool make by Mono Kote to prep the wood called the wood picker works great

@AJHewson1 2 года назад

Except it isn’t made anymore. Im now using a derma roller

@remotelyinteresting9998 2 года назад

Alex you gotta switch to a 50hz based frame rate to prevent flicker on your headcam.

@AJHewson1 2 года назад

Did that, changed the frame rate settings, tried an ND filter and some other setting recommended on the net. No change unfortunately

@CarbideGames Год назад

It’s called rolling shutter. Can be dealt with in post if the camera isn’t smart enough to sync. Otherwise nice vid! Thank you.

@ckafam 2 года назад

How did the wings come out? I would love to see the finish product. Great video thanks

@AJHewson1 2 года назад

Thanks! Will add the finished product in future videos

Mucha resina, se puede hacer con la tercera parte.

What glue did you use to attach the LE tape? Did you only apply to the foam

@AJHewson1 2 месяца назад

@@markfisher8943 3m77 to take the LE cloth in place. I applied to both LE and fabric as it’s a contact glue

@markfisher8943 2 месяца назад

@@AJHewson1 I would have thoiught the contact adhesive would effect the Epoxy bond between carbon tape and the underlying foam? It would create a barrier?

@@markfisher8943 the 77 and some others are designed to break down and not effect the epoxy. I’ve been using 3M 77 for this purpose for 20 years

Hey Alex, Doesn’t the Resin cause the foam ?

@AJHewson1 3 года назад

Hi, I didn’t follow the question sorry

@MohamedHetta 3 года назад

@@AJHewson1 Doesn’t the Resin cause the foam to melt due to the over heating during cure time ? ✌️ Sorry about that, must have said it in my head without typing it.

@AJHewson1 3 года назад

@@MohamedHetta nope, it doesn’t exotherm with a slow hardener. Also as soon as you use it over a large area, it reduces the chance of exotherm. If you leave a cup of resin, because it has a large volume in one spot, it will exotherm

@MohamedHetta 3 года назад

Awesome ! .. One more question, is there any rule that constraints the amount Resin one should use ? like a Resin to Fiber ratio ?
