blob of silicone on the front of the tank just below the neck. Slide
the tank in place into the fuselage, pushing it in until the neck goes
into the hole in the firewall. Do not push it all the way up tight
against the firewall. Leave it about 1/8" short. The blob of silicone
on the front of the tank will act as a spacer and cushion between
the tank and the firewall after it dries. It will also keep the tank
away from the ends of the engine mounting bolts that may be
protruding slightly past the back of the firewall.
❑
4) Now, working through the opening in the top of the nose,
run a small bead of silicone seal on each side of the tank body
where it contacts the fuselage former. The will keep the tank from
sliding backwards in flight. If the tank ever has to be removed for
service, you can cut the silicone loose and get the tank out.
THROTTLE PUSHROD
The following instructions describe installation of the throttle
pushrod materials that are included in this kit. This pushrod
system should be adaptable to almost any typical 2-stroke R/C
glow engine, like the Irvine 1.50 shown in the photos. Gas
engines and 4-stroke engines may require a different pushrod
arrangement and different materials (not supplied).
❑
1) Two throttle servo cutouts are provided in the plywood tray
built into the fuselage, one on each side. Use the side that best
suits the throttle arm on your engine. Mount your throttle servo in
the plywood tray, using the grommets and mounting screws
supplied with your radio system.
❑
2) Locate the 1/8" od x 18" Nylon Pushrod Tubing, the 1/16" x
18" Stranded Steel Cable, the 1/8" x 5/8" x 1-1/4" plywood Throttle
Tube Support (has one rounded end with a hole for the tube), the
Pushrod Connector assembly (hex brass body, nylon retainer, and
4-40 x 1/8" socket-head bolt) and the 2-56 Solder Link.
❑
3) Drill a 9/64" dia. hole through the firewall, aligned with your
engine's carburetor throttle arm. From the front, insert the 1/8"
nylon pushrod tube through the firewall and into the fuselage,
leaving about 3" of tube sticking out in front of the firewall (typical
when using a 1.20 or 1.50 2-stroke engine).
❑
2) Fasten both leaf springs of the tailwheel assembly to the
bottom of the fuselage with the M3 x 14mm PWA Screws.
❑
3) The tailwheel’s coiled steering springs will be installed later,
after the fin and rudder are attached to the fuselage.
FUEL TANK
❑
1) Assemble the fuel tank as shown. Be sure to label the
"vent" and "carb" lines for later identification.
❑
2) Trial fit the tank in place into the front of the fuselage to
familiarize yourself with how it mounts. The front of the tank should
fit through the hole in the firewall. The main body of the tank is
supported by the contoured hole in the fuselage former. Take the
tank back out of the fuselage.
❑
3) Apply a bead of silicon adhesive around the neck of the
tank, where it will contact the inside of the firewall. Put another big
