My Fokker DVII Project

Gaining 20 Lbs 2" or less from the C/G is not as desireable as 20Lbs near the prop!

I don't quite understand?

If ballast is an eventual requirement anyway, then "functional" weight gain on or near the CG should reduce the required weight to trim by moments,.. making that desirable.

I've been out of the business awhile, Is that not a correct assumption?

Kinda, the landing gear is only 2" in front of the CG, the 20# would best be served 4' in front of the GC point

You will make up some in that you will not be carrying ammunition.

As Dan-san stated, louvers are seperate pieces inserted through openings from the back of the panel and riveted in place.

Hi,

I have a question relating to an issue discussed earlier in this thread, around post number 601, page 61 of this discussion.

Does anyone know how accurately the colour was matched when the Knowlton Fokker D.VII cowling was re painted? As I am sure we all know, restoration work is not always carried out accurately or authentically, and I was wondering how close the colour of the engine panels is to the colour of the original paint. Does anyone know? Also, every existing Fokker D.VII seems to have its' engine panels painted a differrent colour. Since I am replying to a discussion, I can't refer back to the photos I was just looking at, but it seems to me that the Knowlton D.VII has cowling panels which are a very light greyis olive green. I have seen the Deutsches Museum's Fokker D.VII and it has very dark brown cowls, and the Musee de l'Aire's D.VII from memory has very dark olive green engine cowls. I do have photos but I am not looking at them right now, but that is my memory of the D.VII's in French and German museums.

Any help will be greatly appreciated!

Regards,

David.

Ah yes,..now I understand. I momentarily negleted to think of the CG as the fulcrum. So yes the 20 lbs is better off farther forward.

Still, if you had to gain weight, I suspect the undercarriage not to be too bad a spot.

Thanks for the refresher!

[Jeff Brooks]

My goal is to try and build this plane as close as possible to an empty weight of 1500Lbs. Ideally, If I were able to build the plane with all the parts at the exact same weight as the original ... then I should only need to add weight under the engine to match the weight of the original engine. But things are not working out that way.

Jeff,

I imagine with a modern engine like the Ranger or Gipsy Queen, we could expect some useful nose weight by installing a battery and an engine starter...but I'm sure you already know all this.

David,

Keep your eyes open for a future OTF article on this subject. My MA thesis deals comprehensively with the Canadian war trophy aircraft. As part of my research, I have located the surviving documentation from the 1963 RCAF restoration of 6810/18, and I'm getting very close to tracking down the surviving individuals who were involved in the process.

Working from these sources, I plan to address a number of the questions that are floating around about this aircraft - including how it originally came into Canadian hands.

Cheers,
