Maybe you can answer this question; since I’m doing Kempf’s first plane, what makes up the landing gear braces on his gear? It looks to me that there are two streamlined tubes going from the main supports to a strip of metal that crosses the air foil. But how is this strip connected to the ribs; is there another strip on the bottom; or is it just screwed to the tops on the ribs? It also looks like there is a strip of metal wrapped around the L/G support tubes where the bracing tubes connect, (I know this sounds very confusing at this point sorry

(do you think this could be considered Fokker Geek talk

)) which would be typical of Fokker engineering. Any one else have any info; it would be greatly appreciated.

Thanks
Ed

Ed,

I will check my photos more closely, but I seem to recall that these field-mod support tubes were simply two small, round (not streamlined??) tubes (? dia) that extended aft from the upper, rear main landing gear strut (24x53x1mm), and attached to a cross tube support that went the width of the trailing edge of the sub-wing. I imagine this cross tube would have some sort of attachment to the upper surface of the sub-wing.

On several different occasions I have tried to mentally go thru the steps to assemble to Sands style landing gear and it looks like it is a one way exercise, definitely not able to remove the wing. I think that the origimal Fokker wing was removable in two pieces. That is how I would like to build mine. I would be happy to buy the drawings. Achim, or anyone else, are the gear wing drawings available separate from an entire aircraft set?

....it looked like the wings was removeable in the DR1 that RFC Pilot and his crew are re-doing. Perhaps they can help? I like the idea too.

I will get more on it next time I am in (Saturday).

Sorry, but WRONG! "Fokker-built" landing gear airfoils were NOT removable on any designs of their Dr.I, D.VII, or D.VIII. However, you will note that D.VIIs built by O.A.W. and Albatros DID modify this non-removable Fokker-built design in order to split their airfoil section into TWO assemblies for removal and easier serviceability of the bungee shock cords. Fokker-built designs, in addition to the standard side bungee access holes, had only small access holes cut into the bottom of the ply airfoil to service the bungee cords (possibly a "field-mod?"). Also, on Fokker-built D.VII types, you will sometimes see a "field-mod" where the two outer ends of the ply airfoil have been cut back a rib width in an effort to allow service of the bungee cords. I have never seen this done on production Dr.I types.

Thanks for the correction on the airfoil. I'm not by any measure an expert on Fokker DR1's, I'm just trying to build a close replica. I greatly appreciate any help, correction, constructive critisism, prayers, beer, that anyone has to offer.

"Bitburger" for Dr.I information will suit me!

Prost!

Spaten Optimater (spelling?) goes well

Thanks Gary,

I am continually amazed of the amount of detail everyone brings to the party!
