10. Locate a .074 x 36" [914mm] pushrod wire. Cut it to a
length of 12" [305mm]. Screw a nylon clevis onto the
threaded end of the wire approximately 20 turns. Slide a
silicone clevis keeper onto the clevis. Slide the wire into the
pushrod tube, attach the clevis to throttle and slide the clevis
keeper over the clevis.
Note: If you will be installing an electric motor you will have
to make a few modifications to the servo and receiver trays.
Steps 13 to 15 show the required changes. If you are
installing the glow engine skip ahead to step 16.
11. To prevent any interference between the receiver and
the motor, ESC and batteries we have provided a secondary
receiver/battery tray and a secondary servo tray. The
receiver/battery tray should be used if you are using LiPo
batteries or NiMH batteries. The secondary servo tray is only
needed if you will be using the NiMH batteries. The NiMH
are too long to allow the servos to be used in the primary
servo location and the extra weight of those batteries
requires the servos to be located further aft to help with the
weight and balance. Locate the plywood receiver tray and
the plywood servo tray.
12. From the 12" [305mm] balsa tri-stock cut two 2-1/2"
pieces and glue them to the receiver/battery tray as shown.
13. If you will be installing the secondary servo tray, glue
the plywood doublers to the tray as shown.
14. Glue the receiver/battery tray in place as shown. If
you will be using the secondary servo tray, glue it in place in
the notches in the side of the fuselage.
15. Important!! This step is only required if you are
installing the NiMH battery pack. Skip this step if you will be
using LiPo batteries. Cut the plastic pushrods at the
locations shown. (There is not a specific location. They just
need to be approximate.)
