Ben Harber designed this amazing 1 : 9.65 scale Boeing PT-17 Stearman built from ADMAS Readi-Board (a.k.a. Dollar Tree Foam Board).

History:
The Stearman (Boeing) Model 75 is a biplane formerly used as a military trainer aircraft, of which at least 10,626 were built in the United States during the 1930s and 1940s. Widely known as the Stearman...

80" PT-17: Flite Fest 2023 Community Challenge – Barnstormers!

So, after a long-stalled start I am finally ready to kick off my build for the Barnstormer challenge. Anyone that knows me knows there was only one choice for me to build. Some may remember this incident from a few years ago... This plane was patched up and has been my favorite bird for...

I see in the listing that this should include the vector files for this build. I find the PDF download includes bitmap images only. How do I get the vector format for this file?

Where does it say anything about vector files?

Fair. I am new to this resource and assumed a file in AI format would be included, which would have the vector paths defined. I was looking to cut these components using a laser vrs my old hands and a knife. Are vector files available?

 

[ROBERTO SUPERCHI]

Hi it is not possible to use these planes in LightBurn to cut them with the laser, you can have vector planes. Thanks and congratulations

It's not an AI file, it's a PDF. The PDF is in raster format, as you have already discovered. A vector file will not be provided at this time.

Awesome! Thanks to all involved. Thanks Ben!

Another amazing plane! Looking forward to this build. I use Inkscape to create Gcode for a needle cutter to cut out the planes. I have used this method on several PDFs from Ben/Sponz. However with this PDF file I am unable to ungroup them fully to to move and remove objects, delete lines, etc.. Any help will be great. Again thanks for all you do.

The raster format pdf serves its purpose.
If you want to use a cnc to cut the parts, you'll need to start by tracing each part line by line.

Thanks, I now understand what the raster format is. This one will be worth the time tracing.

Hi sorry for the dumb question - if we want to print out the PDF full size, what size sheet is this? I see some are small A, but the larger are D or E size (old drafting sheet size terminology) I assume? Thanks!

I'd love to see some comparisons between the Ben Harber & Johnny Gum versions. I built the Johnny Gum design a few years ago and it is still looking good although it's always been a little tricky to fly. I wonder how this one will compare?

The PT-17 is a gorgeous airplane, and we are all lucky these folks are willing to share their plans with us. Much obliged!

I didn’t need anything else to do….but how can I resist? Dawn Patrol was so much fun last year.
Thank you Sponz.

I can't speak to flying the Johnny Gum version (never heard of it actually) but Ben's design flies beautifully. VERY scale if you want it to be. Once I had the thrust angle right for my setup landings were a non-event and it did whatever I asked it to.

Any chance of the XL size plans coming out??

Thanks, Wilmracer. Here's the link to Johnny Gum's plans & build- been around for a few years. Looks like I'll have to try Ben's design and see for myself!
