Tail feathers installation
Kinematic requirements:
Elevator
The necessary servo-side control range is +/- 4mm. Choose a short servo horn for this servo, which will yield higher
precision for the elevator’s motion. (In the same way as ailerons...) This will then yield a very high precision of the
elevator trim.
The original elevator horn’s height should be trimmed down to 10.5mm before being glued to avoid hitting against the
tail boom. For even motion the wire must be perpendicular to the hinge with the elevator at the neutral position.
Rudder
The servo control range is +/- 4.5mm. (Rudder control’s maximum motion range suggested of +/- 14 mm). Using the
same servo horn as for the elevator servo will yield a very rigid control, helping retain and transform as much energy as
possible during the discus launch and release of the glider
