Mounting The Control System - Pipistrel Sinus Build Manual

Mounting the control system

Before mounting the control rods, you must drill a 5mm hole in the cabin floor underneath the
aircraft to allow any condensation or water to drain from the aircraft (at the deepest part of the
cabin, where condensation could possibly build up). Afterwards, put the small red sticker
supplied over the top of the hole to mark its location.
Mounting the bell crank:
Place the bell crank under the floor so that the forked end sits near the flap handle and

the other end near the carbon support underneath the cabin floor.
Put the flap handle in the zero position.

When mounting the front end of the bell crank, be sure to apply Loctite 243 (blue) to the

nut's threads beforehand. Furthermore (very important), place a wrench between the
bearing and the end of the bell crank during the process of fixing the assembly to the
carbon support (i.e while tightening the nut). This will prevent the bearing's housing
from rotating and any possible damage.
Then tighten the rear end of the bell crank. Use blue Loctite 243 here as well. Mark the

front nut and the rear bolt with red paint.
