Today's work
Is a pain in the ass when the ATC is not working. Ideally you want to set the machine and go home. When you return next day the part is done.

The evil twin has arrived  VD~

The aluminium plates are used to hold the nose section and the back section together in perfect alignment so I can sand in assembly. That way when I assemble the nose section to the rear section the parting line will be perfect or so I am dreaming of.

Traian,

Absolutely outstanding!  H^^

I've never seen this kind of workmanship in this Forum before?

There's also balloon bladders that are placed inside the mold and the material. When inflated they push the material against the mold. I believe some parts are made this way, wings for an example.

Or am I thinking of something else?

Great work!

Charles that is called “inflation bladder molding” it is good for parts that are fabric only like a only carbon fuselage (when you lay the material it stays on the mold walls without pulling off the mold) and for that you need a rigid mold because it has to take the pressure without distorting. I will use this technique in making the wheel pants for this bird. Ant that is the only place I will use this technique. And baloons are bad for bladders because the epoxy eats then they burst and make a mess. I had many of them burst and destroy hundreds of dollars 💵 worth of material.

Happy thanksgiving to everyone thanks for watching I hope we all learn something new and make better stuff all the time. Also thanks for all your impute and friendship.

Since the machine is not behaving I am using the time polishing the fuselage molds. The part I do not like about this material is that is hard to see what is done or not done. As soon as it is wet (wet sanding) you do not see anything in there. You have to sand blind, and you have to dry it out and see the results from sanding.
But if that is the worst I am taking.

Wing molds are done ✅
Working on polishing those things
The flaps are built in the molds so there will be one step layout for the wing mold followed by the joining plus a little hardware inserts

Impressive work Traian!

Do you intend to use kevlar or comparable to hinge the flaps as an integral part of the layup?  Any concerns that the hinges will be too stiff if so?

Dave i can go either way with plastic hinges or Kevlar. If i go Kevlar then i will use a light Kevlar 1.7oz one layer of it for hinges. I left some 1/32 flat gap at the hinge which should give a nice flexible hinge. There are other alternatives of using several short hinges instead of a continuous one. Nylon cloth is also an option this will all be decided as the project evolves.
Thanks Traian

Traian,

BAM! You certainly have that airfoil down, locked and loaded!

You did mention an era for composites and a new look at building construction and materials for electric. Interesting your project being started just in time to celebrate 2018 with just that happening with the REvolution!

Well named also, a 'revolution' that model is!

I am getting almost every day material in for this. Some from oversea some local.
I was playing with battery compartment and this is what I came up with. It can be configured for any TP battery pack whether it is a 3S up to 6S and i f i go with anything under 6S i can adjust it up and down in 5/16 increments. Each rail (gray color) is held in place with one screw.

On my to do list is
Face plates (end plates for the molds) For the fuselage (2) one for the wing mold and one for the horizontal stab mold
Templates to cut components.
I will need templates for foam for carbon. That means templates to cut big parts and also I will means templates to cut several patches and small stuff. Each part gets several templates made.
Hardware
Take apart hardware control system hardware motor mount hardware battery compartment formers maybe landing gear stuff.
Paint templates most of the templates are vinyl cut but some are not.
I need to make special formers root ribs and hard points. these will be 1/6 balsa with 90g carbon on both sides.
I need to make sanding jigs for the fuselage inserts and cut the foam that will plug those areas.
Right now I have all the material on hand.

Some initial decisions for layout solutions (which i call best guesses) came after getting advice from may in the composite world specialists and some of the CL molders that dared to endeavor in this direction.
Fuselage will be 200g/M2 one layer with one layer of .75oz fiberglass cloth. and some reinforcements here and there. In the deep cavities there will be Divinycell machined to correct shape and 90g carbon on the outside. In the nose area i can go with perhaps 2 layers one 200g one 90g or the 90 will be patches here and there
Horizontal will be CW30 on the outside 1mm foam and .75 fiberglass on the inside. for spar I am usisng unidirectional 100g/m2 the hinge will be Kevlar
The wing will be same as the horizontal except the foam is 1.5mm.
So there is where I am heading.

Traian,

Ohhhhhhhhhhh My Gosh!

Hey! Do you have any idea how inadequate you make me feel? I can't be the only one?   n~

Where did you learn all these techniques? This can't be your first attempt?

Traian,

You should get the "Builder of the Year" award for 2018.

Charles I have spent some 5 years plus in the glider community building DLG and learning a whole bunch about the composite construction techniques and have spent hundreds of hours just researching. I have learned about just every molding techniques there are possible and practiced them all too. In the process i made a CNC machine from scratch learned to do hot wire cutting and also made my own gravity hot wire cutter i learned about vacuum bagging regular molding techniques then about inflation bladder about layouts then moved to CNC molds (I do this for a job as I am a machinist) once i graduated to CNC molds then it open the door to do hollow molded components then the solid core components was next also a one piece fuselage was in the works too so I have learned to make that too. It was quite a journey a exiting journey full of disappointments and success.

Traian,

I kinda figured you had some background or experience with these kinds of materials. What you are doing doesn't happen over night.  H^^

Certainly puts the old school method of wrapping balsa skins around a foam mold or using planking around a crutch.

Guys like me certainly can appreciate your abilities and your 2018 contemporary approach to modeling.

Your better than me.

Better than anything I've seen actually. This means your efforts give guys like me ambition.

However, even with the ambition, what you are doing is far beyond the reach of most modelers. My 'reach' isn't long enough.  LL~ 

I used planking strips on Pushy Galore. It tired me out.  n~  Some guys are still doing sheeting over foam. It works for us old school guys.

I'm thinking, with all that engineering, math and tooling, you could go into production. I mentioned I have someone interested in your design AND would consider a model.

Are product sales in store for the future?

Good for you!

Right now I am not sure about sales. Mainly because I don't have time to do this.
Speaking of Pushy i think you took the hard way approach to it. It is relatively easy to make a buck out of a few formers put foam between them and make a plug suitable to mold cigar-ish shaped objects. For mold you can do it with two layers of balsa wood cling wrap Elmers glue and Ace band aids. That is easy to do. after you mold you lay it flat and the you walk a Exacto knife blade around the parting line.

Traian,

I'm well aware of the method of which you describe. I made a choice and decided to build from the inside out, as I generally do.

I'd have to do my homework but I'll take a guess, I believe Lockheed, in their early days, the 20's possibly, built aircraft just about the same way. They pressed plywood together in large molds under tons of pressure to make fuselages.

I like planking because I've built many models this way. I have plenty of planking left over from many Berkeley kits. I'm kidding.

I may remove the wings on Pushy Galore and use what's left as a tether car.

Started to work on hardware. This piece will be glued directly in the mold when i close the two halves. There is a 4250 in the picture but the AXI F2B will bolt right in. The motor mount closes the airflow to the outside on the motor. All airflow will travel through the core of the motor. It is not clear in the picture but on the outside of the mount there is a rough surface to get a good glue joint.
Enjoy

Flaps control horn.
This one adjusts the flaps. If you need to tweak the flaps you loosen the screw adjust tighten the screw done. The wire is set in place with a set screw (4-40) on one side the wire is sticking out a little (1/16) and on the other side it is recessed a little.
