After the gluing on
the mount tubes,
trim the tubes.
Clipping the tubes
about 1/16th
behind the motor
mount foam. This
will allow for thrust
angle changes.
To mount the motor, start by mounting the poly tubing to the motor, or to
the X-mount without the motor.
Before gluing the tubing to the plane, spread a thin layer of glue around
that area that the tubes will glue to. Tubing should be glued to sides of
plane as shown. This arrangement puts the torque of motor pushing
against surface and not pulling away from the foam. While the glue is
setting twist the motor against the plane. This will self center the motor
on the nose of the plane.
