13. Drill a 1/8" [3.2mm] hole through the fi rewall inline
with the throttle arm on the engine. Important!! Do not drill
into the fuel tank! The bottom of the tank is 7/8" [22mm]
above the top of the brushless motor cooling hole cutout. To
allow for some error, be sure that your hole is 5/8" [16mm]
or closer to the cooling hole cutout. If in doubt, remove the
tank before drilling your hole. Drill a hole through the second
fuse former inline with the fi rst (a long drill bit is helpful here).
Insert the 1/8" x 9-5/8" [3mm x 245mm] nylon pushrod tube
through the holes. Use CA to glue the tube to the fi rewall.
❏
14. Cut off the excess pushrod tube 1/2" [13mm] behind
the third fuse former.
❏
15. Install the .039" x 13-3/4" [1mm x 350mm] throttle
pushrod with Z-bend into the outer pushrod tube and
connect the Z-bend to your engine throttle arm (you may
need to remove the arm from the carburetor to do this).
Install a screw-lock pushrod connector into the outer hole of
the throttle servo arm and test fi t it onto the servo. A pushrod
support is provided and can be glued to the third former. You
may need to sand or cut this part to length depending on
the pushrod position. When satisfi ed, slide the support onto
the pushrod tube and glue it in place. Tighten the aft end of
the throttle pushrod in the screw-lock pushrod connector (do
not cut off the excess length of pushrod until you have used
your radio system to center the servo and have made your
adjustments to the pushrod position).

16. Run a bead of medium or thick CA glue along the
brushless motor cooling hole cutout lines. Trim the fuel tubing
