When I purchased my Coupe 4 years ago, it was slug slow (88 mph).  On 
Sid's recommendation I took off the cup landing lights on the landing 
gear and gained 5 mph, took off the tube gas caps on the wings and 
gained another 2 mph.  I was then up to 95 mph and enjoying the extra 
speed.  We then had a long chat about the snubber cable.  I took it off 
and gained another 2 mph, but I didn't like the way it landed.  The 
nose wheel hits much earlier (and faster) and it would have a tendency 
to wobble.  It took more work to make my landings feel good and I gave 
up on the snubber removal after 6 months. I don't have the faring on 
the nose but since I don't like the feel of no snubber landings, I 
don't plan on trying that one.  Sid is right, it does make for more 
speed but at a price.  I still like the snubber cable for holding the 
nose wheel off the runway longer.

Subject: [ercoupe-tech] Observation on snubber cable versus drag

 














 

 

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.
