REFLECTOR: Altimeter v. Airspeed

[Tom]

Interesting that yours is tight, I've got all kinds of air leaks. I've 
not been overly concerned as most flying is in Florida. Curious though, 
the worst leak is the large holes where the canard elevator tubes rotate 
up and down with pitch inputs. There has to be a gap between the tube 
and fuselage for elevator movement, how do you keep that area from leaking??
