1.8 Attaching the mechanics to the sub-structure
(bag U2-5)
Place the main gearbox (from Stage 1.6) between the sub-structure side frames, engage the
round shoulders in the sockets, and fit the M3 x 16 socket-head cap screws and washers to
hold the parts together. At the front the mechanical aggregate is secured using M3 x 20 socket-
head cap screws as shown in the illustration. Drill 1.5 mm Ø pilot-holes in the fan housing, and
fix the front structure adaptor 4450.15 to the fan using 2.2 x 9.5 self-tapping screws. Attach the
RC box 4448.101 as shown.
When you need access to the glowplug, remove the two lateral retaining screws and fold the RC
box to the side.
At this stage the meshing clearance of the first gearbox stage should be adjusted as follows:
loosen the M3 x 12 screws on the sides of the motor mounts, run a strip of thin cartridge paper
between the gears, and tighten the screws again firmly in this position after applying plenty of
thread-lock fluid to the threads. Remove the paper strip, and the gearbox should rotate freely.
