􀀀 Step 8
Place a #8 steel washer on each of the 8-32 x 3/4-
inch Phillips head machine screws. Insert the screws
into the mounting holes in the engine mounts.
􀀀 Step 9
Press an 8-32 blind nut into each hole from the back
of the rewall. Apply a drop of threadlock to the
threads of each engine mount screw and install the
mounts with a #2 Phillips screwdriver to draw the blind
nuts into place. Note that the relieved areas of the
engine mount webs face to the right.
􀀀 Step 10
Use a cutoff wheel in a rotary tool to cut 5 3/8 inches
from the threaded end of the 17-inch steel throttle
pushrod. Shorten the end with the Z-bend by 1/8
inch, this will prevent the pushrod from contacting the
engine cylinder. The remaining pushrod will be 11 1/2
inches long with one plain wire end and one end with
a Z-bend.
􀀀 Step 11
Use a hobby knife to trim the nylon throttle pushrod
housing to a length of 8 3/4 inches and insert it into
the hole drilled in the rewall in step 5. Slide it in so it
protrudes 1/8 inch from the rewall and glue it in place
with canopy glue.
􀀀 Step 12
Use a hobby knife to remove the mounting tab
(narrower section) from one of the short plywood
standoffs. Slide the standoff onto the throttle pushrod
housing inside the fuselage.
􀀀 Step 13
Slide the throttle pushrod into the housing from the
rewall end and insert it into the EZ link on the throttle
servo. The screw will get tightened in a later step.
