Total fuel capacity for acrobatic 51 liters (13.4 US Gallon) in acro tank.
Usable fuel capacity for acrobatic 49 liters (12.9 US Gallon) in acro tank.
2.4.2 ENGINE LIMITATIONS
a) Tachometer gauge
-Max. Take-Off (max 5 min) 2700 RPM
-Max. Continuous 2400 RPM
NOTE:
If not stated somewhere else (refer to section: 4.12 Acrobatic Maneuvers) the aircraft may
be operated in acrobatic maneuvers up to 2700 RPM.
b) Oil-temperature gauge
-Max 245°F
c) Oil capacity
-Maximum sump capacity: 16 qts.
-Minimum sump capacity: -Acrobatic: 12 qts.
-Normal: 9 qts.
d) Oil pressure
-Minimum Idling 25 Psi
-Normal 55 - 95 Psi
-Starting, Warm up
Taxi and Take-Off 115 Psi
C A U T I O N
It is normal for the oil pressure to "flicker" from 10 to 30 psi when going from upright to
inverted flight. During knife edge flights and zero-g flights oil pressure may drop and the oil
system may not scavenge resulting in engine failure or damage if flight is prolonged. Knife
edge and zero-g flight should not exceed 10 seconds.
W A R N I N G
If oil pressure drops to 0 psi the propeller pitch changes automatically to coarse (high) pitch
with a corresponding decrease in RPM. Apply positive g to avoid engine stoppage.
e) Fuel pressure
-Max 40 Psi
-Min 18 Psi
-Min Idle 12 Psi
