HE motor alignment on Phoenix is very
critical. To install the motor mount accu-
rately, you need to build a jig.
Remove the J-1 and two J-2 parts from the die
cut plywood sheet and clean up the edges.
Slide the 1

" outside diameter liner tube
over J-1. Slide the J-2’s into place as shown.
The front end of the liner tube should be
flush with the front ends of the plywood
parts. When all the parts are properly
aligned, glue the liner tube, J-1 and the J-2’s
in place with CA.
The motor casing should be slid over the
liner tube as far as it will go. Apply masking
tape to the casing until it is a snug but not
tight fit in the 1

tube over the casing until it is flush with the front of the cas-
ing.

F-9’s with a

Installing the 6-32 blind nut is a bit tricky
since there is not a lot of room in the back of
the pod. Set the fuselage on the bench upside
down. Set the blind nut on top of the tail-
boom and slide it aft until it is under the
hole. Insert a 6-32 screw through the hole
and thread it a few turns into the blind nut.
Now pull the blind nut into place with the
screw. Once the nut is started into the hole,
you can tighten the screw to pull it fully into
place.
Remove the screw and apply some thin CA
around the nut so it doesn’t fall out.
