Default Fokker DR-1 with Saito FG-36, 1/4 Scale Balsa USA

Here is a 1/4th Scale Balsa USA Fokker DR-1 Project. I picked it up today from builder Ray Walsh in Waterloo Wisconsin. Ray has been working on it for me for the past 5 months and has it ready for paint and final radio installation. (That's Ray on the left of the photo and me on the right.) His craftsmanship it great! The airplane is beautiful. Our agreement was that he would build and cover the DR-1. I would do painting and radio install. This looks like it's going to be a nice machine.

Some features to note on the construction:

1. I am using the Saito FG-36 Gasoline 4-Stroke. So the firewall had to be recessed back to accommodate the long engine. A second firewall was the answer.
2. I've flown other Balsa USA fighters and was never happy with the stab incidence. So Ray had an idea that would allow it to be shimmed. If you look closely at the stab you will see that it is bolted down from the top. Which will allow changed if needed.
3. The covering is un-painted Nelson Fabric.

I am looking at colors. Something different. Yellow is cool. Fokker Dr1 577/17 of Ltn Rudolf Klimke, Jasta 27, Halluin-Ost is my scheme. I will post a picture of it once I get it scanned. Leo

Looks good. I have flown mine with a saito 180 for over 5 years now. Just be sure to fuel proof the heck out of that axel wing. It takes a pounding from the fuel. That FG 36 will be a lot of power for that plane. I have considered the 180 over powered on mine but I sure like how it flies it. I have been playing around with inverted and knife edge flight now that I am comfortable with it. Great design and a lot of fun to fly. You will very much like it.

Here are the colors I am going to do. It is Dr-I 577/17 of Ltn Rudolf Klimke. His mother made him put an Anchor on his airplane as a good luck symbol. Maybe it will be good for the life of the model as well. I will be working with flat latex colors.

Vertical Grimmace, Yes the engine may be large but I like adding big engines rather than adding all lead to the nose. This way I can swing a big prop, 22 X 6 with no trouble. If I have too much power I can throttle back. Leo

I am sure you have seen mine fly at the Warbirds over the Rockies event. I have mine done in the Ritter von Tutchek scheme. Black and green. I am sure you are not over powered. It will be fine. That airframe can only go so fast. Maybe we can do some formation flying this summer if you guys make it out again.

Leo, where did you get that great glass cowl? That would go great on my D.VIII...


I'd love to see this plane and any other like it at 2009 Rheinbeck Fly-in. I'll have my D.VII and by buddy's D.VII both in Jasta 10 colors. I may have my D.VIII or a Pup done by then too...

Evil, if you want the best cowl available, get the 2 piece aluminum cowl from Glenn Torrence. http://www.flygtm.com/web/pages/NEW-PRODUCTS.htm

Evil, That cowl is from Fiberglass Specialties. http://www.fiberglassspecialtiesinc.com/ The cowl for the DR-1 and the DVIII are identical. My son is building (Re-Building) a DVIII that I crashed and it will use the same engine and cowl that I have put on this DR-1. They will be a nice combination to fly together since they are powered and propped the same. That make a huge difference for good formation flying. Leo

Thanks guys.

Vertical, I knew about GTM's cowl, but after the horror stories on getting these things to stay in the air, I'm going with something a bit less expensive.

Leo, thats why I was asking since they were identical, I figured I could use it. Funny thing is Fiberglass Specialties markets them as two separate pieces! USA-20 is the Dr.1 and USA-24 is the D.VIII!

I'm powering my D.VIII with a G-38. Yeah, a bit over powered, but since it flies the D.VII so well I figured it would fly the D.VIII better.

Evil, I have never even had mine come loose. It is held on just like the full scale with a cable. It is a good system. Not sure of the price difference. I just like the scale looks of the GTM cowl. I had to move my engine back 2 5\8" to get the engine to fit. It was lot of work as a retrofit but very much worth it in the end.

Vertical, I meant the entire D.VIII not just the cowl.


I have the cockpit kit from GTM that I'll be building for the D.VIII, and his fabric too. The fuse of my D.VIII will more than likely be lozenge.

Evil, are you building the BUSA DVIII? From what I have heard, they need negative incidence to keep the plane from lifting off too early and then stalling. It seems like the DVIII would be an easy plane to fly but that does not seem to be the case. However you go, good luck.

Yep, I have the BUSA D.VIII got a pair of them from an estate sale for less than $100 combined.

Why not utilize the ABS cowling included in the kit? Once trimmed, fitted and glassed inside, they work great. I've built several of the BUSA W.W.I models and all cowlings holdup perfectly well to vibrations and exposure to the intense Florida sun.

Mostly because it looks like crap Nick. I know the BUSA Fokker D.VIII isn't very scale, but I can't help but to want something a bit better.

The glass one doesn't look half bad and it is better than the ABS one from BUSA.

Vertical,

I remember your airplane. Nice. I took pictures of it and recall how it looked so good all grimy in the dusty pits. I don't know if it was because you built it that way or if it had just got so dirty because of the dusty environment we were in, but either way it made it look all the more authentic. Here are some pictures I took of your DR.1. Leo

Evil, I think the thing that looks so bad on the stock cowl is how long it is. I think to get the nose to look right, you have to box the engine back. The torrence cowl forces you to do this because it is the scale length. I agree though, If I were building one otherwise, I would use the fiberglass.

Spychalla, Thanks. I did weather the airplane when I built it. I just cannot see those WW1 aircraft looking clean and new. I love my DR1 and have really gotten the hang of flying it. It does a great spin!

The best Latex paint jobs I have ever seen were done by Chuck Hamilton over in Buchanan, MI. I've painted with latex before but never got the results that he can get. So rather than mess around with unknowns I decided to go to the source and do it right. I called Chuck and he was gracious enough to give me all the details. It starts with BEHR brand flat exterior Latex from Home Depot. I had them color match 6 quarts of paint for me today to some Testors Model Masters German RLM color coupons I had prepared. The colors look dead-on to what I gave them to work from. Total cost was $69. It is thinned down for spraying with window washer fluid. Any brand, but "fresh" as Chuck puts it. So I got some fresh stuff. As a trial piece I sprayed a rudder that I just recovered on my DVII. Paint was thinned about 50% for spraying. I applied it directly to unpainted Nelson Fabric. No priming required. OH! You wouldn't believe this paint! It is fantastic! Some of the best stuff I have ever sprayed! Good coverage, layed down smoothly, did not run or sag, didn't have to wear a mask, and cleaned it up with water! This is going to be fun.

Once things are dry Chuck recommends a clear coat using Minwax water based PolyAcrylic. He says it goes on well with good adhesion and it keeps the latex from absorbing grime and makes it easier to clean-up. So you see some in the picture and I plan to use it. It was about $8 a can. Leo

Leo,
Thank you for the kind words.

Do me and everybody who is reading your thread a favor . . . do a weight study.
Weigh a particular part BEFORE you paint it, then weigh it AFTER it has cured.

I think we will all be happily surprised at the results.

Paint on!

Chuck

Does the blue color in the windsheild washer fluid cause any issues with the paint?

Merlin,

The blue tint does not have any color effect at all. It evaporates off. I think that's why I have good results using "fresh" windshield wiper solvent.

Thanks Chuck. I'm just about ready to paint my D.VII (just gotta do the carbanes and inter plane struts), and this looks like a good solution for me.

Would it work to add Nelsons cross linker to the Behr latex to make it more fuel proof? I have some of that laying around. Also do you filter the paint when filling your spray gun?
