Page 3: Equipment Selection
EQUIPMENT SELECTION Engine: The Pacific 27% Gee Bee “Y” is very light for it’s size and it will fly very well with a mid- size gasoline engine. It was designed to use a classic, heavy 43 to 62cc engine (with tail-weight added), or one of the new, light 40 to 50cc engines, (with nose weight added). -

Page 5: Installing The Main Landing Gear
There is a string attached to a small block of wood, tack glued inside the servo opening. This string leads to the hole in the top of the wing near the root rib where the servo lead must exit the wing. There you will find another wood block holding that end of the string. - Page 6 main strut assemblies. Also drill 3/32” pilot holes through the mounting flange of the fixed pants, one in front, one in back and one on each side. INSTALL THE MAIN STRUTS. Attach the main strut to the gear mount in the wing, using three 8-32 x 5/8”...

Page 7: Assembling The Fuselage
Center the wheel in the opening in the pant and then tighten the wheel collars. Twist the sliding pant until the axle is lined up with the leading edge of the wing, then drill 1/16” pilot holes and attach the fixed portion of the pant to the wing using 4 of the 2.6x10mm Phillips head self tapping screws. - Page 8 sure that your engine will be centered over the alignment marks on the firewall. Drill the holes and install the engine, using a thread-locking compound on the bolts. Cut a block of 1/2” thick scrap balsa approximately 1” x 1 3/4” to act as a spacer to keep the fuel lines from crimping against the firewall.
- Page 9 meets the fuselage. Remove the box, spread 30-minute epoxy behind the line and reinsert it into the fuselage. Set the fuselage aside until the epoxy sets up completely. INSTALL THE THROTTLE AND CHOKE SERVOS AND PUSHRODS. Although the choke can be operated manually, we recommend that you hook it up to a servo for ease of operation and to provide a way to stop the engine from the transmitter.
- Page 10 with 30-minute epoxy. The epoxy will give you time to set the dummy engine/cowl assembly up as shown and to carefully center the dummy engine within the cowl. INSTALL THE COWL MOUNTING BLOCKS. Locate the four factory covered hardwood cowl mounting blocks. Glue them into the notches in the fuselage nose ring with the long axis of the blocks running across the fuselage.
- Page 11 ATTACH THE STICKERS. It will be much easier to put the stickers on now, than later. See the picture for their proper location. (Run the rudder stickers parallel to the ribs in the fin. The bottom of the fin is not parallel to the direction of travel.) MOUNT THE STABILIZER.
- Page 12 Screw the bracket in place with the two 2.6 x 12m self-tapping screws provided. Push the wheel collar up under the bracket and tighten the setscrew to hold it in place. INSTALL THE ELEVATOR SERVOS. Add a 24” extension to each of your elevator servos and use tape or shrink tubing to secure the connections.
- Page 13 Pass one end of the cable through a crimp tube and through the hole in the threaded adapter. Loop the cable back through the crimp tube in the other direction, leaving about 3” of cable past the tube. Now loop the cable over the tube and pass it through the tube a third time going away from the clevis.

INSTALL YOUR RECEIVER, SWITCHES AND BATTERIES. We like to put the switches in the cockpit floor ahead of the pilot, but you can put them almost anywhere that strikes your fancy.
