Not quiet so. The fairing also exists for these types of scissors. Not 
available from Univair anymore, but they used to be.

 

I am having one.

Hi Ed, 
 
The major effect, in my opinion, is that the partly extended nose gear , with 
the fairing still attached, not only increases drag, but makes the nose gear 
assy a second rudder. This affects a properly rigged Coupe, by incresing the 
effectrive rudder action, thus upsets the "co-ordinated flight control system". 
 If one wants to restrict the nose gear extension, suppossedly to gain an 
increas in airspeed, then one must surely remove the fairing. Notice, that 
later coupes were equipped with molded nose gear links, and no fairings.

Fred Weick said in a recorded interview that having the fairing on the nose 
gear made almost exactly one (1) mph difference in speed.
 
What we didn’t explore was, isn’t that 1 mph difference comparing the nose gear 
all the way extended with the scissors snugged up to the back of the strut tube?
 
In that case, the scissors wouldn’t make much extra drag as it is hiding behind 
the tube.
 
When the strut extension is limited, then you have some shortening of the tube, 
hence less drag.  But you also have the scissors hanging way out where it 
commits drag all on its own.
 
Could there be as much as two (2) mph difference between having the nose gear 
extended with the fairing versus having it 2/3rds down with the tube and 
fairing both providing their maximum aerodynamic drag?
 
Just wondering.
 
Ed
