Example loading problem:
Aircraft empty weight: 230kg (506lbs)
Pilot 1: 90kg (198lbs)
Pilot 2: 110kg (242lbs)
Total: 430kg (946lbs)
Max AUW = 450kg, therefore (450 - 430)kg = 20kg or 44lbs
The specific gravity of fuel is taken to be 0.718 g/cc (1.58lbs/cc)
Therefore maximum fuel = 20/0.718 = 27 litres.
3.3. CENTRE OF GRAVITY
Trike
The centre of gravity (CG) of the trike is not very critical - it only affects the range of pitch control movement, not
the trim speed. The CG of both the rear seat occupant and the fuel are as close as possible to the hang point
with the trike in the suspended attitude, so the suspended attitude is little affected with load variation. Solo flight
is from the front seat only.
Wing
The CG of the wing is critical. Due to the materials used and the quality control in manufacture, the CG of the
Quik-GTR wing does not vary significantly in production. Items should not be attached to the wing which
significantly change the CG. The hang point position on the wing keel must not be moved from the designed and
tested position. There are two hang points on the keel, the REAR position should be used with the QuikR trike.

NOTE

For all other engine data refer to the engine manufacturers handbook supplied as a supplement to the Aircraft
Operators Handbook. See also Section 4.

For 912-
S engines, an overload clutch with “lost motion friction damping torsional vibration absorber” is fitted
for smoother startup/shutdown. This weighs 1.8kg.
