3 cylinder Radial / Re: Another reason to own a 3d printer

« Last post by Dan_ on June 07, 2026, 01:41:33 PM »

I looked for a sim in the interweb that showed when the plugs fired.  Not one in the world I could find.  So I had my AI bot make one...
Where is says 3 cylinder radial simulation, look over to the far right and click the plus sign...

That is very cool.  I see that on you tube there is a link to thingiverse for the print files.  Now if we can build one large enough it would surely be lighter than the verner.  But then range would be limited to how long a hose we have to connect to the compressor.

What are Legal Eagle layouts? Do mean copies of the plans?

Hi, Tom Kyler here, new builder.  I too am performing a 3D 'virtual build' to help understand the plans and construction.  For those interested and software saavy, an alternative to Solidworks is Blender 3D, which is free and a relatively small download.  The learning curve is still required as would be expected with any new software, but I believe it is no more complex than Solidworks (which I use in my engineering day job).  Blender is NOT a CAD software, but rather a generic 3D/animation software...no history based or parametric modeling, but its ridiculously quick to build geometry for "what if" scenarios.  The following work I did in about 2 hours.  Note that I do use a CAD package (Vectorworks) to develop the design dimensionally from the plans...but then I use the CAD reference dimensions as inputs to Blender 3D.

Tom anychance you would share that file with me Im metric and find imperial difficult to work with. Jon

Hello, I'm looking for Legal Eagle layouts. Can you send me images of the layouts or a PDF copy?

Not to worry, Chuck. You have wisdom and experience on your side. He only has the guile of youth.

XL / Re: XL empty weight, with various engines?

« Last post by Chuck in Indiana on June 03, 2026, 10:14:15 AM »

FWIW a flight instructor friend was talking to the GADO, and he said if it had one seat, a 5 gallon gas tank, and looked like it wouldn't go 100 mph, it was an ultralight. Period. 
For the OPs question.. an XL *can* make ultralight weight. Barely.

I too would be very interested in this information.  It would be educational to have a chart of weights and options for various XL's.  For example, my build is shaping up to be (Verner 3V, 20" bike wheels, Oratex covering, etc).  I'm planning on Oratex because of lack of weight information to ensure I keep as light as possible.  It would be nice for a way to submit information annonomously in case a build is squeezing the limits a bit too much.  But on the other hand, that probably is very rare.  Right?
