Bird of Time HLG (oz12664)
About this Plan
Bird of Time HLG. Simple all-sheet glider model.
Direct submission to Outerzone.
Quote: "Hello, My name is Rodrigo Burgo, I'm from Brazil. The lines of the Bird of Time (oz2093) glider have always caught my attention. So, I thought, why not make a HLG version for fun? So I started to make some doodles and ended up creating the project I'm sending [model photo & more pics 003-007]. The built model is 7 grams total (with ballast). Very light construction, with wings created with hand-sanded profiles, dihedrals and gull wing structure with folds in the balsa plate. A light and very attractive model, for flights on windless days. Guaranteed fun."
Update 13/12/2020: Added alternate version of the plan, to print on 8.5 x 11 paper, thanks to JanNovick.
Supplementary file notes
Alternate plan (8.5 x 11).
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsMy computer warns me this is exactly PDF compliant, it being PDF /A.. it "may cause issues". Check it?

Seems standard to me. I am using free Reader DC on a Win10 PC to view PDFs. When I open this one, I get an info bar at the top saying "This file claims compliance with the PDF/A standard and has been opened read-only to prevent modification" and I also get a button to "Enable Editing". There is no warning. I see no issue :) Most importantly, this is the file and format that Rodrigo (the designer) sent in to us. I am not keen to start editing/hacking his file.

I too got that message with my Windows 8.1 when opening the downloaded version. I clicked on "enable editing" and the message goes away. I then saved the plan again and the message does not come back. I printed at full size on standard 8/12" X 11" paper and saw that it would crop off some of the white area around the plan and a very small section of the rudder.
I can live with that!

OK thank you ..Delving further; file does work despite Dire Warnings from My Tracker software PDF suite ..Seems it's an old (iffy?) Corel conversion pdf, not being fully pdf compliant.

So the file also works fine, for you. So there is no issue - other than your chosen brand of PDF viewer throwing up a warning message. Here at Outerzone we recommend users view the PDF files with Reader DC, see https://outerzone.co.uk/knowledgebase/entry.asp?ID=104. Using other software, you're on your own - in the sense that we can't support you, or indeed replicate your issues.

Hello guys, I only exported it in pdf ... the drawing is in Corel Draw and must be printed in A4 or in a scale that can be printed in A4 .. if it is of interest it can be reduced in % at the time of printing.

Hi Rodrigo. It's all good. Many thanks for the plan :)

Stits' Paradox: "The shorter the wingspan, the longer the comment section."

For those who would like it, I'm submitting a copy of Rodrigo Burgo's Bird of Time HLG re-formated to reproduce on U.S. Letter size paper (8.5 x 11)
Jan Novick - 13/12/2020
This is a nice little design and plan--thanks Rodrigo. I'm curious about the difference between the "flat span" of the drawing (20-3/8") and the 44cm (17.3") that you reference in the notes. The only way I could get that measurement ("projected span") was to set the inboard panels at 48º dihedral, with the outer panels at 0º. Your photos appear to show a much shallower inboard panel dihedral... (BTW, when I selected "Allow editing" of the pdf, the measurement tool became active. it is very handy for calculating area, angles, etc.)
Dave D - 13/12/2020
Ah, right. I think maybe the model shown in the pics is a slightly reduced scale version? Certainly the wing on the plan is ~ 20.3 inches
SteveWMD - 13/12/2020
You are correct... I reduced the scale to be able to use some balsa wood leftovers I had in my hands ... if I remember correctly, it was 90%
Rodrigo Burgo - 13/12/2020
Where are the dihedral details?
Pat Meehan - 19/12/2020
For gullwing, first section with 20 mm and in the second section 10 mm...

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
