The individual sub-assemblies can now be brought together as shown in Fig. 15; please note the
following points: the tail rotor is on the right-hand side, as seen from the tail looking forward. The
tail rotor drive belt has to twist through 90° to the right (clockwise), as seen from the front (take
care not to turn it more than once !!!). Slide the tail boom into the holder in the chassis in such a
way that the two U-shaped cut-outs on either side of the tail boom engage in the locating lugs
moulded into the tail boom support; when you are satisfied that this is so, push the tail boom
forward as far as it will go, then tighten the four screws against the self-locking nuts in the
holder.
Now place the main gear and belt pulley in the chassis, wrapping the toothed belt round the pul-
ley at the same time (don’t twist it - see above); guide it between the two tensioner pulleys.
Place the brass spacer ring between the main gear and the lower main rotor shaft bearing. Fit
the main rotor assembly through the upper rotor shaft bearing, the belt pulley, the main gear and
the spacer ring from above, and into the bottom rotor shaft bearing. Push the cross-pin through
the hole in the main rotor shaft, provided that the hole is still accessible above the belt pulley,
then press the shaft into the belt pulley to the point where the cross-pin engages full-depth in the
moulded-in channel in the belt pulley.

Fit the freewheel sleeve onto the bottom end of the main rotor shaft (the end with the two cross-
holes is at the bottom), and slide it through the lower rotor shaft bearing into the freewheel of the
main gear to the point where the two cross-holes line up with the cross-holes in the rotor shaft.
Ensure that the lower rotor shaft bearing is pressed fully upward into the bearing bracket; the
grubscrews in the upper collet (below the swashplate) also have to be loosened to allow the ro-
tor shaft to be pushed down far enough.
When the freewheel sleeve is correctly positioned on the rotor shaft, slide the lower collet into
place (with the shoulder at the top). Apply thread-lock fluid to the M3 x 14 socket-head cap
screw, fit it through the upper cross-holes, and tighten it firmly.
Now hold the chassis securely and pull the rotor head up as far as possible, pulling hard; in this
position press the upper collet firmly against the upper rotor shaft bearing. Tighten the two grub-
screws securely in this position.
