Took this at the Dayton Dawn Patrol. The highlight was seeing a period rotary motor run in a replica DR1.

Hello! New guy here...

Building this one from the Dollar Tree foam board. Fuselage is almost done, still need to glue the servo tray. Du-Bro hinges have been ordered for the rudder.

But I've hit a snag, as the upper wing exceeds the dimensions of the board.
Can the upper wing be safely constructed in left and right halves? Debating the use of Armin wings, as well.

Thanks!

It looks brilliant, so far! I used the larger sheets of Elmer's brand board you can buy at larger office supply stores in the USA. It's a bit thicker than $Tree so I scaled the plan up 10% to keep the wing loading abuot the same.

My wing was one piece but, I spliced a set of similar wings in the middle. I butt-glued the two pieces, and after drying. I made two cuts (at 30 and 60% wing chord) with a sharp knife and put two pieces of 1mm carbon rod (6 inches long) in the wing, for spars, bridging the splice. I put a bit of white gorilla glue in the cut and then covered it with 1-inch wide Scotch gift tape to control the foaming until the glue cured. Then, I removed the tape and proceeded to paint. If you need dihedral, you can use a small, bent piece of piano wire instead of carbon.

It turned out very strong. I hope this helps you thinking.

Thanks. There is a Staples store very close by, I'll check for the larger board.

Since it is a bit thicker, could I sand it to an airfoil shape, perhaps?

You certainly can but, at our size aircraft, it would be mostly cosmetic. I do not remove the paper from the Elmer's board and paint them for moisture resistance. I've been building some of the planes designed by RCGroups user Old_Pilot, and learned that from him.The paper accepts rattle-can spray paint well. If you remove the paper, be sure and spray from 12-18 inches away, to keep the spray propellant from eroding the foam.

I sometimes glue a piece of balsa to my foam wing leading and training edges and sand that. It sands better and provides some impact resistance.

Also, if you are intent on giving a wing a camber, look into the "Jedelsky airfoil" or "Jedelsky wing." It is a simple way to build a airfoil wing with flat pieces, like our foam and balsa. It works quite well.

After applying many gallons of hot water, I removed the paper from the Elmer's board. Without paper, it is just about the same thickness as the DTFB. I've cut the top wing out. Cut the lower wing from some plain old DTFB, have yet to cut the middle wing.

I think I will just leave wings flat, with rounded edges. Going to add the TE scalloping as others have done, though.

Glued in the servo tray and the forward fuselage bottom. Ordered the prop last night.

Started making wheels from 7/64" vacuum tubing, foam and these 59 wooden smiley faces from Michael's.

The black painted piece is 3.5" in diameter.

I had to bin my O ring wheels as Ugly and heavy
Also found that a vacu formed Cowling was Infinitely superior (lighter Too) to multi layers of foam sanded to a 'sorta' scale shape.

Enlarged the cowl as others have done. I've since affixed the 'faceplate' to the front of the cowl, still needs shaping to the proper rounded profile.

I need to purchase some thin foam (dinner) plates to make the 'cheek' pieces that blend the cowl into the fuselage sides.

Middle wing has been cut, the prop arrived on Saturday.

Wow, that's a nice looking pair of Fokkers! When did you build them? Been flown yet?

I believe I did them back in 2010 or maybe 2011. At that time I was flying mode 1. I had just started RC Helicopters which was mode 2. So I was a little afraid to fly them for fear I would have a brain servo problem.

Sense then I've moved to Florida. And started fly UM & UMX planes here at home in the back yard. Starting with a champ what almost flies itself. Anyway I have mastered flying fixed wing mode 2 pretty much???. As I said earlier I learned to fly RC fixed wing mode 1 in 1972. So I took a while to get the hang of mode 2 fixed wing. I'm still have a long way to go to get to where I was mode 1. But I'm getting there. I'll probably never attain the skill level I had 30 years ago!

I do what to finish the black one that is a Depro plane. It still needs the ailerons cut out and servos installed. Also the battery box and receiver installed. But I have all that stuff I just need to get to it! The red DR1 in Home Depot Pink foam. Lots heavier? However the red DR1 is ready to go! But the black one is real light. Should be a great flier. Just like Steve meant them to be!

Going with a Lothar von Richthofen paint scheme.

The laminated foam cowl is done, aside from installing some neodymium magnets.
Speed controller arrived the other day.
