Set the trim handle to full forward position and remove the safety sticker covering the hole on top of
the horizontal stabilizer and the tape covering the gab between horizontal and vertical tail surfaces.
Now use the enclosed “T” key to push the safety pin screw down while spinning it counter-clockwise
until it is completely loose. To detach the horizontal tail unit push it forward using rm palm strokes
until the unit pops out.
When detached, always place the horizontal tail unit onto a soft surface to prevent damage.
Normal procedures
Fitting the horizontal tail surfaces
Horizontal stabilizer and elevator MUST be united during the following procedure. To t the horizon-
tal tail surfaces rst set the trim handle inside the cockpit to full forward position. Make sure the pins,
their holes and bushings have been cleaned and greased!
Lift the joint stabilizer and elevator and slide them into position by pushing them backwards while
the elevator is deected DOWN fully. Now use the enclosed “T” key to push the security screw down
while spinning it clockwise until the screw is completely tightened. Pull the “T” key out and make sure
the safety pin holds the head of the screw, so that eventual unscrewing will not occur.
At the end tape the gap between horizontal and vertical tail surfaces and cover the hole on top of the
vertical stabilizer with a sticker. Check control deections for smooth, unobstructed movement.
