Default 1/6th Scale DO-335

Ok Guys besides the HE-111 I was also asked by the same customer to put together his new 1/6th Scale DO-335 in Solidworks so that can have some nice shots of it for construction book. Iwill also be prototype building this plane once Iam finished. The plans are really nice looking and colored to make things easier to read. there is even a complete electrical diagram sheet set up , plus it is electric so no worries about coolong and mopunting a rear engine plus at 1/6th scale it will be easy to transport.

Here are a few screenshots of the plans Iwill post more pics as Iput the plane together in solidworks.

Since right now theres no construction manual Iwill be figuring it out as Igo, however for now it seems to be built over a center crutch top and bottom halves.

So there is the Plans for the most part Now I need to import some stuff into Solidworks and start extruding the parts. this will give me a rough Idea of the finished weight too

Looks like your "customer" also has some very impressive 2-D CAD skills! That certainly makes collaboration (commercial or otherwise) much easier and we'll be seeing more and more of that. We'll also be seeing many more Isometric construction drawings instead of photos in product manuals. Flair did away entirely with text descriptions of construction on their Puppeteer Mark II in favor of isometrics.

While I have a deep love of hand-drawn plans as objects of beauty (and find CAD drawings rather ugly), designing in CAD greatly enhances (if the user is strict with himself) the likelihood of a truly scale design. However, as I've said at other times in other places, I think there's a danger that using CAD can push designers to design in certain ways that may not be compatible with the "spirit" of the original, an example of this is the "3-D puzzle" approach.

Also I suspect that the days of having to work with two different CAD softwares are numbered. I don't know what 2-CAD was used here, but soon (or already in some cases) all you'll have to do is click "Render 3D."

yea I try not to do very much 3D puzzle as a lot of times it adds a lot of extra weight. But I will use the puzzle approach in some areas just because it adds strength. Right now I am trying just to figure some of the stuff out on this plane and having to use the plans to extract parts yuck

Once you get to stress-skin metal construction aircraft (think "WWII) the whole idea of "scale internal structure" on a model sort of goes out the window...or it's truly pointless. On the other hand, with WWI models, my attitude is "the inside IS the outside" so there's very little reason to "redesign" an already perfectly good design. It just needs to be "translated" into model materials and sizes.

At the same time, I have to admit that the complexity of building WWII models, and particularly something like the DO-335, scares the bejeezus out of me.

yea all my WWI models I design as close as possible to the original cause it all can be seen through the fabric plus they light weight enough its fun to make them look original.

but areas on a WWII plane line motor mounts lg mounts and some flying surface mounts having puzzle cut makes them much stronger than just flush glueing the side of ply to the face of another ply piece. not to mention to properly glue ply or pourous wood like balsa you put a thin layer of glue on the area where glue will be applied let it dry then glue the pieces together. this was taught to me by a furnature maker as he explained wood naturally will pull the glue away from the joint so you need to seal the pores by double glueing

Oh i love the DO335, what wingspan is this one? What drawings did he base the outline on?

it's like a 90" wingspan and calls for 2 Scorpion S-5535-190KV Motors

As for the drawings he used Ihave no idea but Iwill check on it. when Iprototype it Imight convert it to the type 10 2 seat nightfighter Ilike the lines on that better and all it basically is is adding a little to the top

I have plans for a gas 104" version but find the prospect of an electric intriuging.

Ive built 2 of Don Smiths and they were a total pain and I found a lot of engineering needed just to cool the rear engine so I thought Electric could be fun for this and this will be my first serious electric

definietly electric and maybe consider putting one of the motors in the scale location and use the scale cooling outlets rear of the radiator and in front of the rear spinner. Hey if your gonna do it in cad might as well see if it can be done

Fiberglass cooling ducts would be fairly simple to fabricate for this thing..

well guys it is already done I am only putting it together in Solidworks to make sure everything fits and to have some good detail shots for the instruction manual for individual areas etc. then I need to build it so can see whats going to go on. Since it isnt my design or anything I am doing just the usual minor changes for unfitting parts and the instruction manual. from there if he needs molds for different things he will let me know.

Here is where I am at the moment. it takes a bit to do each former as Ineed to convert them for solidworks but its speeding up

Ok Ihave all but 2 angled formers to go then to do a few things. Ineed to adjust the holes for the air tanks or adjust the tanks themselves. and then add all the other little items
