Go for it Monkey. I love the old planes. Good luck and keep us posted. A nice build log would be cool too.

I took the overview plans and enlarged them in photoshop. I then took the digital files to the blueprint shop. They printed it out on 36"x48" sheets and for three sheets I paid under $10.

I then used wax paper to trace the parts to be cut out. Then cut them from BluCor. Which I painted today with a air paint gun, using Kilz.

I am now waiting to see what I do next...

All right, where are the pictures, hmm? Grab that little camera out of it's holster and upload those things. We demand our rights as WattHeads to have complete and up-to-date photos on all things FlyingMonkey. :D

you have all the pictures so far...

what, you want a picture of the wax paper?

The foam is still out, waiting for the paint to dry, and for me to decide on a finished paint pattern.

Put it Together? And yes I would like a picture of the wax paper- I like wax paper.;) How long ago did you paint it? I always glue mine together first, then paint them, but whatever floats your Monkey boat.:) I am very disappointed you didn't get many (any?) pictures at SEFF '08. Sort of disturbing really. See how disillusioned I am?:)

Well, I will let you in on a little secret then...

I am working on getting around the rules of an upcoming fly in. Next month at Hodge's they are holding a warbird meet. The requirements are that for mono wings that they must be at least 80" and multi wings be at least 60". It must be a warbird, or a civilian craft that was used in a military role, and is in military colors.

They say nothing about the accuracy of it's scale appearance. So, I am curious if they will allow this profile foamy.

I plan on taking an abundance of images at this event, and also plan to do a complete FM Report.

Hopefully this will ease your mind.

Hillbilly built me a Sopwith Triplane from those plans.....It sure does fly sweet!!

An enormous DR1 from those plans will be really cool...:tc:

ok, question for the WWI history buffs.

Where to find documentable WWI color schemes for this plane? As if it was going to be in a historical scale competition?

scaleRCflyer has a huge collection of WW1 books etc......and he also has a lot of links to websites....He helped me choose the scheme for my DR1.....

I lost all the bookmarks I had accumulated when my old PC's motherboard/CPU failed.....Still haven't figured out how to retrieve them from the hard drive...:(

I like it! Bigger is better :D

Big profile foamies fly really really well. Im very pleased with my BUFY project.

Ive been wanting to do a big foamy bipe of some type. I was leaning towards an Ultimete or Pitts but the WWI birds sure do have a special appeal all their own.

Whats been stopping me is transportation.

Im guessing yours is going to end up around 50" span? I was wanting something in the 60" span range but anything over 50" is too big for me to transport or store fully assembled. Even at 50" I couldnt get any other models in the truck with it and I like to take several to the field at the same time.

That means I'd need some way to make the wings removable. Doing removable wings is possible and not that hard for a single wing. For a bipe its more than twice as much work and hastle. You need a system that is not only strong enough but will keep the wings properly aligned once assembled.

Doing removable wings on a tri-plane would be too much work for me to tackle!

What are your plans for a power system?

Larry

I am planning on 60"

Yes, transportation is an issue.

This one will be solid, as a test bed.

Power system, well, I'll tell you if it works, otherwise I'll lie and say it was designed to be a glider or static model :D

flyingmonkey, what auw are you shooting for w/ this fokker? cause ive got an extra welgaurd 2800kv outrunner that i put on a profile yak w/ a 62" span it it was a great slowflyer, but i still had enough power to punch out of a hover w/ a 3s1p 1800mah pack... and im thinkin w/ a 10x6 prop it would fly semi-scale like

FlyingMonkey
05-18-2008, 12:12 AM
Thanks Tom.

I just ran across that before you posted, and I made a link to one of their "main" pages. (They don't seem to have a home page)

My main concern now is, keeping the wings rigid enough for flight. That's a lot of span they have.

You're giving me way too much credit on my building skills here...

monkey 2 words flying wires....

Balil
05-18-2008, 12:15 AM
i look at it this way. if you get her built. and she doesnt fly. thats a great static piece.... then scale it down enough til you get it to fly. ya know.

FlyingMonkey
05-18-2008, 12:19 AM
Actually, I am tempted to go the other direction.

It will never make a good static piece, it's already too ugly, stupid blucor just doesn't look good without a lot of patient work.

But, I am also looking at some of the thicker insulating foam I have, and thinking it would make an even better building material, and would finish even nicer. For the second version of course. Removable wings for transport, stuff like that.

Balil
05-18-2008, 12:35 AM
what size is this thicker insulating foam? and one thing i was just thinking about is how would you attach flying wires. so hmm id like to see this thing once its done.

FlyingMonkey
05-18-2008, 01:06 AM
The Dr-1 didn't have flying wires.

The thicker foam is about 1/2", maybe a little more.

I think it would be the same stuff BUFFY is made from.

Balil
05-18-2008, 01:13 AM
hmm no flying wires eh? guess you need to stock up on cf rod and spars... :p

FlyingMonkey
05-18-2008, 01:22 AM
Yeah, I was wondering how I would get it rigid enough.

I just tested something that eased some of my concerns

If your going to use the same foam that BUFY is made from you will need some reinforcement for sure.

One of the bad things about that blue DOW foam is that its not nearly as tough as the Depron or even bluecore.

Any point loads - like landing gear or motor mounts will need ply plates to spread the load over a large area. You have to be carefull how you go to pick it up too. The foam crushes and breaks easily.

So far the wing spars system I used is holding up very well. Im doing routine snaps and knife edge 1/2 loops and tight flips and no cracks even. Its holding up very well for flight loads so far - even hauling around some heavy floats at times.

My span is about 70" and it weighs about 5 pounds without the floats. Ive got the inequivalent of 3 6mm carbon tubes in the wing. Two running thru the center for the removable spars and one full length for each aileron that also act as hinges. The elevator and rudder also have a 6mm tube as a spar/hinge.

The foam I have is the DOW blue Styrofoam building insulation stuff. I think they call it 1" but its actually 5/8" - 3/4" thick.

Ive considered trying to cover each side of a wing with fiberglass and WPU or perhaps even using paper or silkspan or parachute fabric (any non-stretch nylon or poly fabric would work) as a covering with WPU. The foam is thick enough (I think) to act as a box spar if it was glassed/skinned in some way so it could handle the bending loads.

I'll be watching to see if you come up with any good ideas I can "borow" :D

Good luck

Larry

Fred, you should get about 6 yards of Thai Silk for the Triplane. Buy some water based polyurethane as well. You will still need either CF or balsa spars to carry the wing loads. Silk and WBPU will really stiffen the skin and you can paint it with just about anything after that because it seals the foam. I think Larry3215 is dead on the money with his advice, even though I haven't built with blucor. I know it's floppier and softer than depron, so it is going to need some toughening. You look like you've got a good start. If it doesn't fly the first time, don't give up on it. I can wait for your pictures. Isn't that nice of me?;)

Bob

P.S. You might want to set up the wings so they are all removable. I have seen it done in a Flying Models article on a large scratch built jet liner. Takes some work, but it will save you space when you travel with it.

My suggestion would be a cf ply of the flat strips. They are fairly inexpensive and you could use them on leading and trailing edges. On the smaller versions only the leading edge of the lower wing was re-enforced this way - but on some I did use a spar on the top and bottom wings respectively.

I should think that a couple of strips of CF layed out end to end (I would do 25" strips at least - but maybe go for the whole 30") and then a shorter "doubler" ply of the same CF CA'd across the center section to create one long strip of rigid CF for the leading edges and smaller sections for trailing edges.

Since the plan calls for the "fuse" to be "doubled" in several places and the fuse sides are doubled at the motor mounting area I should think it would need very little CF strengthening - maybe a thin tube down mid fuse (front to back past the cockpit?) would do.


By the way - if you used the DOW blucor FFF - then you might try RUSTOLEUM spray paint - I tried them all (Kilz, Krylon, etc.etc..) and the RUSTOLEUM paints did the best coverage without melting the foam. ALL of the others would penetrate the outer shell and eat into the foam to one degree or another no matter how many "light" coats I used. The rustoleum I could spray on fairly heave full coverage coats and it dried well without eating the foam. White was the absolute hardest to get coverage. BTW - denatures alcohol with a paper towel will remove most of the ink printing on the blucor - if left on it WILL bleed through ANY paint!!

I must add that I really am quite impressed and can't wait to see this fly!! It will be great!!

I did not think it could be cured, only controled by building and flying model airplane.
