Well I did not say I believed it just said it was there. Kind of sets all data in perspective does it not?

Yes, very trustworthy indeed. I thought we were past the belief that aircraft data from WW1 is reliable?

But, do carry on, it makes for an entertaining distraction.

Based on the data from memories of 29 officers but memoirs at the time.= unreliable later on = supernottobereliedon.

But equally this is data based on memories.

data ≠ memories

data > memories

data = good

memories ≠ good

good > memories.

good = jesus

jesus > good

good> memories

jesus >devil

data = jesus

memories < jesus

data > devil

memories = devil

You can't model reminiscence anything experienced or remembered is by nature wrong.

wrong = evil >/= memories

I can't seem to find the aircraft speeds as posted a couple posts ago. Example Dr1-200Kmh. Could someone please point that out for me?

Yes, I saw already where the aircraft are listed but could not find any airspeeds.

EDIT:
Never mind. I figured it out.

175km/h for Cl.II

175km/h for Albatros D.II
165km/h for " D.V like we have now!
200km/h for Fokker D.VI
218km/h for Fokker D.VII w/ BMW


Fokker D.VII figures seem about right, which is 200 km/h (not 218 km/h) w/ BMW btw, without use of overgas naturally with which ~225 km/h could probably be achieved.

But the 165 km/h figure for the Albatros D.V must be a typo, even when considering it's the early version with only a 160 PS engine, and I believe the time to climb figures confirm that.

Anyway, the list obviously has errors, and as such shouldn't be taken as definitive in any way.

I'm sure the Germans would've loved a 200 km/h Dr.1 though :lol: 8-)

Replica Pup with Radial Engine

 

http://www.lightairc...hly_article.pdf

 

Some quotes:

 

"In the cruise, if one can call it such, at 1750rpm indicating 70 knots the first thing that strikes you about the Pup is how ponderous

are its four ailerons, for despite the fact that there are four of them they seem almost ineffective. Later, when you get a chance to stufy

them, you see that even though they move through generous angles on the ground, once airborne you can push the stick sideways

as far as your calves will allow but the response at the wingtips is that the ailerons only deflect a couple of inches at their trailing edges

 

The problem is that the aileron circuit takes in the upper and lower wing tather than, as in most four-aileron biplanes, mostly in the bottom wing

with the upper ailoners slaved off the lowers. Consequently, while the down going ailoner is pulled by the stick torques-tube assembly through

about 12 feet of stranded steel cable and one pulley, the up-going one is activated via more than 30 feet of cable, righr across the upper wing, three

pulleys and at least eight connections, all which introduce stretch into the system.

 

... it is noticable that even full rudder either way doesn't yaw the Pup more than about 10 or 15 degrees, and she's neutrally stable directionally feet off."
