Great Planes Yak-54 1.60 ARF - GPMA1411 - Manual (Page 27)

O.S. Max 1.60 FX
❏
1. Slide the spinner backplate onto the crankshaft. Ream
the propeller as necessary to fit the engine and push it onto
the crankshaft (don’t forget to balance your prop!). Install the
prop washer and mating jam nut onto the crankshaft and
properly tighten the nut.
❏
2. Tighten the spinner adapter against the prop nut.
❏
3. Secure the spinner to the adapter with the 5 x 55mm
[3/16" x 2-5/32"] spinner screw. If the screw is too long, use
a cutoff tool such as a Dremel rotary tool to shorten the
screw. Thread the included 5mm [3/16"] nut onto the spinner
screw before cutting. When the nut is removed, it will
straighten the threads on the screw that may have been
deformed from the cutting process.
Note: The procedure for attaching the spinner to a Fuji-Imvac
BT-43 EI engine is the same as the 1.60 FX. However, you will
use the spinner bolt included with the engine instead of the
spinner adapter shown above. There is a longer 70mm [2-3/4"]
spinner screw provided for use with gas engines.
❏
1. Slide the aluminum wing tube into the fuselage.
❏
2. Push the wing panels into position, feeding the aileron
servo extensions through the holes in the fuselage.
❏
3. Use the included nylon wing bolts to tighten the wing
panels to the fuselage. Be sure that the root ribs in the wings
are flat against the fuselage sides.
❏
4. Locate the four holes beneath the covering for the
canopy mounting bolts. Use a sharp hobby knife to trim the
covering from the holes.
❏
5. Bevel the ends of the canopy alignment pegs with
sandpaper. Confirm that they will fit into the two holes in the
front of the canopy.
