Control Deflection Limits
At VNE control surfaces should not be deflected more than one third full range.
VA is the maximum speed permitted in turbulent conditions. Full deflection of the controls at speeds above VA is prohibited.

OPERATIONAL LIMITATIONS
- must not be flown in aerobatic manoeuvres.
- must not be flown at bank angles beyond 60 degrees.
- must be flown under daylight, VFR conditions only.
- must not be flown in known airframe icing conditions.
- must not be flown in conditions of moderate turbulence or above, or in winds exceeding 22 kts, at surface level, less if gusty.
Permitted Manoeuvres
Non-aerobatic operation only.
Any manoeuvre necessary for normal flight. Stalls.
Steep turns with bank angles not exceeding 60
Rotax 912 and 912S
4 cylinder, four stroke, horizontally opposed engines.
Cooling
air-cooled cylinders
liquid cooled heads.
engine oil air-cooled with a small radiator.
B Model aircraft utilise an oil/water heat exchanger in place of the oil radiator.
A carburettor heat control draws air from around the exhaust, via the usual air filter. This should only be activated if carburettor icing is suspected
Prolonged use of AVGAS can cause
damage to the Rotax 912, precludes use of fully synthetic oil and requires more frequent oil and oil filter changes.
To Start:
Main fuel valve, Master switch Electric fuel pump Throttle at idle Brakes Mags (both) Propeller area Rear of aircraft Choke (pulled out) After engine starts, choke Check: OPEN ON ON FULL AFT ON ON CLEAR CLEAR ON Start OFF OIL PRESSURE RISING.
If the engine floods…
Close main fuel valve, half open the throttle and turn over the engine. When it starts, reduce the throttle quickly to idle (2000 rpm) and turn on the fuel.
ignition system check at 3500 rpm
engine speed drop should not exceed 300 rpm with a maximum difference of 120 rpm.
Failure to let the oil temperature reach 50°C can result in
carburettor ice forming during takeoff. It is imperative that this procedure is followed otherwise serious injury or death may result.
nose wheel steering is
conventional and is directly connected to the rudder pedals
When taxiing with a strong tail wind, hold the control stick
firmly in the neutral position.
When taxying with a fully aft cg it is possible for the aircraft to
tip back and sit on its tail skid, particularly if taxiing over uneven ground.
Typical cruising flight (80 hp)
Engine speed: 4500 rpm.
Airspeed: 95 mph (83 kt)
Fuel flow: 2.8 Imp. gallons per hour, (12.7 l/h)
The maximum speed in cruising flight is 118 mph (103 kt).
Sudden loss of engine power:
Best glide 58 kts
trim
Assess wind direction and select a suitable landing area into wind.
