Fokker Dr1 world population

Gentlemen,
By my estimates, there at least 30 Dr1 replica triplanes in the world today, with at least half of them in flying condition, and registered with a national agency.
Do these seem like fair estimates to you?

Yeah, and probably more under construction than there ever were original airframes!

i have looked up DR1s in the FAA database several times- interestingly, there were fewer listed the last time i looked, but that could be an error in their data retrieval- these things do get glitches.

Well, last time I saw a "complete" (note inverted commas :-) list of triplanes that have been built world wide I counted some 80 planes.

I do not know how many of these are actually airworthy and flying right now.

I just know there will be two more "soon". :-)

Cheers!

Eighty seems like an excessive number. Where did you get your info? Who did the estimate?

Peter Cohausz has compiled that list of triplanes when doing the research for his book on Museum aircraft and reproductions. I have that list somewhere, but do not know where. If I recall correct it also lists the location and status of the plane.

I think 30 pieces is what might exist in the US alone :-)

I know of about 7 triplanes in Germany alone.

Cheers!

Well, if Dr.I builders around the world keep it up at this rate, we'll soon have more tripes than were built by Fokker

. That's a good thing in my way of thinking

Well I know of at least 8 in the eastern U.S states, and 4 in California. Thats 10 for sure here in the states that are actually flying. I'm not counting the off-scale tripes and ultralights.
I have never seen a figure of 30 for the U.S, and really doubt the number is that high. At the seasonal U.S big airshows you are lucky to see only one triplane on display, and usually its the same ones over and over again.
Once again..I think that that number (30) would be more applicable to the worldwide Dr1 population. Sure would be interesting to know for sure though.

Perhaps we could put that list together here.

I do not know how many of these are actually airworthy. Those listed here are only the few that come to my mind right away: The list is just in order in which come to my mind.

1 Brussels,
1 Munich,
2 Speyer
1 Michael Vogel (in progress)
1 at Villingen Schwenningen
1 owned and flown by Koch.
1 Aviodome at Shipol NL
1 Eberhard Fritsch
1 Fred Murrin
7 owned by Peter Jackson (5 flying 2 in progress)
1 being built by Stig Svanson in Sveden

I know of about 10 more in progress which are not listed here in the Forum and about 7 more of which I do not have the names handy right now.

This ads up to 35 alone of which I know whithout further research.

I have two in the making and there are about 5 more which are discusssed here in the forum, either flying or being overhauled right now. Not to speak of those planes which are in the making by other forumities.....

So at least we have about 40 in existance.....

I am sure the forumities can add some more whithout big difficulty.

Cheers!

Update:
Ok..accessed the FAA website for U.S aircraft and found 36 aircraft registered as Fokker Dr1s.
Here's the problem. There are a number registered to Robert Baslee, owner of Aerodrome Aeroplanes in Missouri U.S.A. Robert builds 1/2 scale ultralight versions of WW1 aircraft. He has however built a full scale Dr1, but its made out of aluminum tubing and actually has wire bracing between the wings!
Its NOT a true Dr1 replica. So therefore, I wouldn't include these types here.
Safe to say that there are a number of other 1/2 scales out there that are also registered as Dr1 replicas.
I think its safe to eliminate approx. 25% right off the top for these reasons.
So why don't we say that the actual number of full scale, flying examples of the Fokker Dr1 is closer to 25-27? Not including non-flying static museum displays.
