 3. Glue the carbon tube into the fuselage using 6-minute
epoxy, making sure the tube is centered at the front of
the fuselage and pushed all the way back in the notch.
This will be where you will set the thrust line to what you
have decided according to the note above. If you want
the total 5 degrees of thrust you will want to make sure
that the tube is up against the cutout in the horizontal
fuselage. If you want to decrease the thrust, then you may
have to relieve more of the inside of the right doubler
and then glue the tube in with the desired thrust line and
fill the void between the foam and the tube with a small
amount of epoxy.
 4. Mount the motor using 6-minute epoxy to glue the
motor to the inside of the tube. (Be careful not to get glue
into the inside of the motor bearings.)
