How to build a dlg boom 

But of course - excellent! And I enjoyed the quiet sounds of life in the background. ☺️

Most Excellent!

Really great work! It is the best boom for a homebuilt DLG.

I've seen this method done before here on RU-vid. You can wrap the core and the rolled boom with video tape. Use wax floor polish as a release agent. Good job! PS, not seen the hotwired foam core before. I think the guys I saw had a steel mandrill on a slow running lathe to make wrapping easier.

Your technique is good bro

Do you already have a build video online, how you build the rest of the glider, I mean how you fit the wings and electronics to that conic boom? Just know the ones with straight arrow shaft. I have some very similar piece of carbon lying around from cheap decathlon telescope fishing poles. Below 10€ lots of different sized carbon conic poles. Using the bigger ones as camera boom...

Great video, just one thing: did you leave the foam with the epoxi in the boom at the end in order to make it stronger?

By the way, ive noticed myself there are dofferent densities of xps foam, i have a blue one thats really see through and feels more “ airy” were as the other one is yellow non see trhough when put against light and feels really dense and a bit heavier

Isn’t arrow shaft good enough? Is it heavier than the new boom?

This is so genius ! Ill def give it a go once my epoxy arrives, how do you even come up with this🧠

genius :)

What density fiberglass did you use?
