Wing Center Section

Spent a good amount of time this morning working on redesigning the center section structure. There were more "issues" than I originally thought. One significant error was the lack of any keying to define the root of the wing. No keys in the spar, nothing but two vertical grain shear web pieces to gauge the middle. Not a good design.

I added slots to the spar in the center section and redesigned the ribs a bit. Probably overkill, but it's a much better design than before. The center section will be sheeted too.

Have another wall-of-photos. My intent with these photos is to help me to plan the build flow. Hopefully, I'll spot any hurdles or problems before they pop up in the actual build. Please speak up if you spot something that I've missed.

Finishing up the wing structure. Still need to get the wing tips and aileron structure drawn up and pre-fitted. I'll try to get that done today.

I spent some time this evening doing more renders and started asking myself, "is all this worth it?" I guess it is if I decide to eventually kit this bird. If I use these 3d renders in a build booklet or something like that, it might be worth the time. All I really need to be doing is verifying the fit of the parts.

I do like how the parts go together for the wing so far, but I don't like the default random 3ds textures. So for these last few parts I decided to use one of my old video game designer techniques and use photo textures on these last few parts.

I scanned a sheet of balsa for the texture and cut the parts from that. I may have to redo the rest of the 3d model now too. I do like the way these last few renders look compared to the last bunch.

It's virtual building, no glue required, very fun. Fly it on Real Flight, and no regrets when you stuff it in the ground. I think you are doing an excellent job,.... and honing your skills at the same time. Looks great. I'd be afraid to fly it as a streamer combat model in real life through. Save that for the foamies. I'm half tempted to build one just to support your efforts. It looks like a fun model. I already have a receiver with no model assigned to it. Keep me in mind, I'd love to be a beta builder for it. But my calendar is really filled through to June 1st (vacations). No way I can get any building done until then.

Sweet model!

Wait! I do have a 6 week window April 1st thru mid May,..... Hmmmmm. That'd probably be too late for a Beta build,.... But I'll build one anyway if you decide to kit it. Put me down for one of the first run kits.

Sometimes "less is more", meaning fewer parts makes a faster build. I have an early lazer cut kit, and the built plane called the "mini Laser 3D" and it is made up of many parts, and the weak point was the body, just aft of the wing. It was known to break there a lot. come see it if you want to.

Okay Fred, I put you down for one of the first beta "kits"

I do need to come over for a visit. I could bring my laptop so you can play around with the RealFlight model a bit too.

I wont actually be printing plans from 3ds max. What I'm planning to do is to render a very large orthographic projection of the airframe. I take that bitmap and scale it to fit the drawings in DraftSight. Then I can use the rendered image as a background for the actual plans.

I was going to mention this earlier but didn't want to interfere. But what the heck, we are friends. Won't all those indexing letters show through if someone wants to cover it in a transparent? Can they be made smaller, and/or fainter? .....just thought.

Yeah, they do seem a bit much. I just redid a set of higher resolution textures to rebuild the wing to use as fill images for the build plans. Do these look better? I am emphasizing the contrast a bit because a lot of the detail will be lost when these images are transferred to the background of the plans. The rendered images will be used for illustration.

I don't think they will be an issue with the actual laser cut parts. They can be easily omitted from the cutting process too. I'll cut a few sample parts tomorrow to see how obnoxious the labels actually turn out. I want to see how these virtual parts compare visually with the actual laser cut parts.

Yes.
Very nice,... and C-grain no less. Your CAD skills are top notch.

I finished redoing some of the high resolution textures for the structure. I will be able to use the 3d model for illustrations on the plans and in a build booklet. Enough for tonight.

Not sure if you have ever built from laser cut parts but an artists gummy eraser does wonders for removing the charcoal from the edges of cut parts. Way better than sanding which removes wood and just rubs the scorched wood into the good wood.
