REQUIRES A BT-80 QUICK CHANGE MOTOR
MOUNT (sold separately)
The quick-change motor mount system allows you to swap out
different motor mounts in your BT-80 tube size rocket, allowing
it to y on multiple diameter motors, as well as with a cluster
of motors. This gives your rocket a lot of versatility with motor
selection, and could save you lots of money.
This particular kit contains the Fixed Mount that is bonded
into the BT-80 tube, so that the removable motor mounts (not
included) can be screwed into the rocket. This is the part that
is not removable, and you’ll need one of this product for every
BT-80 size rocket in which you want to use the Quick-Change
Motor Mounts.

11. Remove the mount and jig, then use a dowel to apply a
bead of wood glue approximately 1/8” (3mm) wide to the inte-
rior of the tube beginning 3-1/4“ (83mm) from the aft end.
12. Slide the xed mount and jig into the tube and rotate the
mount into the glue (to distribute it over as much surface as
possible) pushing all the way until the jig stops at the edge of
the tube. This will place the xed mount at the correct depth
and ensure correct alignment.
13. Check from the front side of the tube (the open end) that
no glue has overowed onto the installation jig. Clean any
drips with a dowel. Allow the mount to dry for several minutes
before removing the installation jig. To remove the jig, rotate
it counterclockwise until the tabs on the jig line up with the
openings on the xed mount and pull the jig out. The xed
mount is now installed. Allow it to dry completely before
removable mounts are inserted.
14. The xed mount is now installed in the rocket and ready
to accept any of the removable mounts. Using the Quick-
Change Motor Mount System is as easy as attaching the
shock cord to the anchor on the removable mount then slid-
ing the mount into the back of the rocket, rotating it clockwise
until it drops into the slots and nally rotating another quarter
turn to latch the mount into position. To remove the mount
simply rotate a quarter turn counter-clockwise and pull the
mount out of the rocket.
