Weight limits
Basic model weights
WEIGHT ELECTRO
Empty aircraft weight (incl. BPRS and std. battery system) 368 kg (811 lbs)
Maximum takeoff weight (MTOM) 570 kg (1256 lbs)
Minimum combined cockpit crew weight (depends on C.G. of empty aircraft) 55 kg (121 lbs)
Maximum combined cockpit crew weight (depends the weight and balance) see Chapter 6
WARNING! Should one of the above-listed values be exceeded, others MUST be reduced
in order to keep MTOM below 570 kg. failing to comply with any of the weight limitations may
cause uncontrolled ground handling and/or flight due to extreme center of gravity position.
Center of gravity range
•
The aircraft's in-flight safe center of gravity position ranges between 20% and 35% of
MAC (mean aerodynamic chord).
•
The in-flight center of gravity point ranges between 8 ⁄’’ (220 mm) and 14’’ (355
mm) aft of the datum. The datum is the wing's leading edge at the fuselage root.
