14. Wrap the receiver battery in foam and use hook
and loop material to secure it to the receiver battery tray.
❏
15. Install the receiver switch and charge receptacle.
We installed ours just below the receiver battery.
❏
16. Drill a 3/16" [4.8mm] hole inline with the throttle
and choke ball link balls. You may fi nd it easier to
remove the engine before drilling the holes. Cut two
8-1/2" [216mm] long outer pushrod tubes from the
20" [500mm] long outer pushrod tube. Use medium
sandpaper to roughen the outer pushrod tubes. Clean
the tubes with denatured alcohol and insert the tubes
into the previously drilled holes in the fi rewall. Route
the tube through the slot in the former until it is fl ush
with the front of the fi rewall. Use thin CA to glue the
tube to the fi rewall.
❏
17. Reinstall the engine on the standoffs using the
bolts and washers supplied with the engine. Apply a
drop of threadlocker to each bolt before installing.
❏
18. To make a throttle pushrod, thread a 2-56 x 1"
[25mm] threaded rod approximately 3/8" [9mm] into the
end of the white inner pushrod tube. Thread a nylon ball
link socket onto the threaded rod. For the DLE engine,
trim the inner pushrod tube 10" [254mm] long.
❏
19. Make a 1/2" [12mm] long L-bend at the non-
threaded end of the 2-56 x 4" [102mm] metal pushrod.
Thread the other end 3/4" [19mm] into the end of the
throttle pushrod tube. The L-bend makes it easier to
thread in.
❏
20. Cut off the L-bend from the 2-56 x 4" [102mm]
pushrod. Insert the throttle pushrod into the throttle
outer pushrod tube. Attach the ball link socket to the
ball link ball on the throttle arm.
❏
21. Position the throttle stick so that it is centered on
the transmitter. Adjust the throttle servo arm so that it is
centered on the throttle servo. Move the throttle arm on
the carburetor so that the throttle is open approximately
half way. Mark the throttle pushrod where it crosses the
servo arm 5/8" [16mm] from the center of the servo.
Make a 90 degree bend at the mark and secure the
throttle pushrod to the servo arm with a nylon Faslink.
❏
22. Now it should only require minor adjustments
to the throttle endpoints on the transmitter so that the
throttle opens and closes completely. Be sure to also
set up a throttle cut switch on your transmitter to close
the throttle completely, stopping the engine.
❏
23. Install the optional, servo operated choke following
the same procedure.
