Default Ov10-D 96"plan

I was intrigued by the OV10 Bronco,so I decided to model a big one,in cad.In this case,an 8 footer.I was surprised by the size of the cavity in the fuselage and engine booms.I haven't got involved with the minor details,like armament pods and missile attachments,but included flaps.The intent is to make a box spar for rigidity(maybe aluminum?)but there is oodles of room.It appears a good candidate for electrics,especially if you split the wing outboard of the nacelles.I made the solids,from there ,I would extract the lines for the formers and stringers to be cut by Laser.

Default next step

So,I made the solid model,by tracing drawings,and then assembling them in sequence as if I was going to build it.Then I have taken the solid and sliced it to produce profiles at stations
Then,because of the nature of the cad program,I trace(make line drawings of the edge) the profiles,and plan my stringers and the notches in my fuse sections.Laser cut files cannot have multiple lines,at the same spot,hence I cannot just extrude a profile to make a solid fuse former,as that would produce lines at multiple depths.

Hi Alex awesome CAD there
I wish I have the skill to do something like that. Too lazy to learn pass 2D right now
I wanted to do a Super Tucano.. if I ever learn CAD properly

HeHe,I had a Texan II(very similar to the super Tucano) all drawn up on my other hard drive,(damn)which failed.
BY the way,the secret to cad,is to learn to work on different planes(not airplanes).once you do that,you can extrude or draw parts with different orientations, along paths or lines.

Here is a build on RCSB you may have interest in on a OV10. Gains is a Master builder and this is his third build. He keeps improving on his design for weight loss etc.
Will be following yours as I am a big fan of the OV10 and currently flying a 96" ARF

Whiskey,take a side view of the Super Tucano,and put it in paint.net.Then take a side view of the Sig 4Star,and put it beside the Super Tucano.Now,put the Super Tucano on a different layer and make it transparent 50%.Now move that layer on top of the 4Star.Scale it until they are the same length.You will find that there is very little that you have to do,if you follow the 4Star plan,to make it into a Super Tucano Fuselage.

Now,after a few days of messing with formers and stringers,here is the start of the laser filesThe second is without the stringers to obscure the view.Then I take each former and rotate it 90 degrees,to make it align with the page face,and nest these so that there is as little waste as possible.One advantage to working in 3d,is that you can rotate the model parts ,and insert parts where needed,using the many years of experience,that you guys accumulate.

Note how simple the main fuse actually is.The only issue is how you keep the wing mounting area well built,and aligned.

So,after making my laser files,I re-confirm the fit,by extruding the files.and adding the stringers.
