A Couple of Built-Up Boost Gliders

[TheAviator]

Don't have too much to say, just wanted to show these off. The perks of having a laser cutter really shine in the larger bird; the trussed wing looks great and helps with handling while sanding the wing.

Brian,

When are they going to fly ? Looking forward to hearing duration times.

BTW - There is a "typo" in your Signature . . . Your last name appears as "Muzek", rather then "Guzek".

I have an old Full Spectrum 40W Hobby 20x12. 5th gen, I think. The leading edge is made from 3/8" balsa, but carved to ~0.3" thick at the root and about 3/16" at the tip. The leading edge is hand carved with a razor plane and sanding bars.

Hi Brian,

Good looking models, look like carbon fiber booms. What are you using ? Tubes or rods, what thickness?

Small one uses a Hummingbird style balsa boom. Big one uses a DPP Carbon 3mm tube I had laying around. Really wants something bigger, but I had it. 5mm would probably be good. 0.5mm wall.

Is the covering tissue, polyspan, or something else?

They look great!! Really beautiful and well made. So jealous Oh the things you can do with a laser cutter.

Transparent Ultracote. Which I'm pretty sure is rebranded Oracover. Tissue would be lighter, of course.
