Installation Of The Sliding Elevator Trim Knob - Pipistrel Sinus Build Manual

Installation of the sliding elevator trim knob

Fit the sliding elevator trim knob assembly into position under the floor. The shorter

cable must be directed towards the rear of the fuselage and the longer cable to the front
where it does a 180 degree turn and then exits to the rear in the main center tunnel.
It is important to make sure these cables are positioned properly and that they do not to

loop around or bother any other cables and/or fittings under the floor
Secure the assembly with the supplied screws. When fitting the trim knob there are

several important steps. Firstly the cables which attach to the trim knob need to face
downwards, towards the bottom of the aircraft. The washer needs to be positioned
between the cockpit floor and the sliding knob, not on top of the cockpit floor.
Finally, lubricate the whole knob area with clean multi purpose grease. Be sure to use lots

of it because the trim knob runs aluminum on aluminum and, without adequate
lubrication, the mechanism will wear out quickly. Cover the area with tape to keep the
dirt and debris from the greased slider.
