8.4. HANGARING, GROUND HANDLING
Moving the airplane during hangaring, parking, etc. is recommended with
empty airplane.
Steering rod connected to front wheel axle is allowed.
The following list and sketch show surfaces reinforced by extra layers of
carbon, to prevent surface dimples caused by ground handling.
Reinforced surfaces:
- Fuselage-fin connection, circle with radius 350 mm, where
fuselage can be pushed down to lift the front wheel
- Leading edge of fin up to 500 mm height, 100 mm wide on each
side.
- Top part of the wing leading edge, 200 mm wide area
- Top part of the stabilizer leading edge, 150 mm wide area
- Area around fuel caps
- Stepping surface on left wing root - fuselage part
- Whole upper surface of the wing is reinforced, but maximum load
is still limited
- Spinner is reinforced
- Root part of propeller blades can be used for towing, dont use the
tip parts !
CAUTION – airplane surface is created by thinnest allowed layer of carbon
fabric, to keep the lowest possible weight. Under the carbon fibre layer is
layer of PVC foam with relatively low firmness and stiffness. Common hand
pressure can result in surface damage and complicated repair. Gentle
ground handling is therefore highly recommended.
CAUTION – airframe has integrated lifting points for landing gear
maintenance. Metal brackets with nuts are bolted on front wall of fuselage
main spar.
If the plane is lifted by pulling the wings, it is necessary to follow basic
rules. Supported area should be wide enough and below wing spar, close
to checking window of aileron crank. Otherwise wing bottom shell can be
broken or damaged.
