The later kits came with eccentric torque tubes for the elevators which have 
an off set which allows the tube going through the fuselage to rotate 
without swinging up and down.  You can get a pretty tight fit using it.  I 
also built up the outside of the fuselage to create a negative air pressure 
at this opening.  It is basically built up to be thicker in front of the 
torque tube and a depression behind the torque tube.  This will minimize the 
air coming in through that area.

Of course you will also need to blank off the area between the top of the 
canard and the canard cover.  The only way to effectively heat the inside of 
the Velocity is to keep the cold air out.  It can be done!
