2.3 Power Plant Limitations
2.3.1 Engine
The ANT trike may be equipped with either JPX M25 (2 stroke, 25 hp) air cooled engine with electric
starter, or with
Polini Thor 250 LS (2-stroke)
liquid cooled engine with electric starter.
The trike can be equipped with other engines with similar characteristics.
WARNING:
These are non-certified aircraft engines, the possibility of engine failure exists at all time. Do not
operate these engines over densely populated areas. Do not operate these engines over terrain where a
safe, power off landing cannot be performed.
2.3.2 Fuel
The following fuels can be used.
JPX M25:
Fuel mixture of premium petrol 95-99 (Ron) Octane unleaded or AVGAS 100LL and oil at 2.5%.
Synthetic top-quality oil for 2-strokes engines.
Polini Thor 250:
Fuel mixture of premium petrol 95-99 (Ron) Octane unleaded or AVGAS 100LL and oil at 2%.
Synthetic top-quality oil for 2-strokes engines.
2.4 Weight
Maximum take-off weight *, kg (lb)
196-210 (432-463)
Empty weight (with Discus 15T wing and JPX engine), kg (lb)
81.5 (180)
Empty weight (with Discus 15T wing and rescue system), kg (lb) 87 (192)
Permissible pilot weight range, kg (lb)*
55-111 (121-245)
*-depending on the type of wing and engine, with full fuel tank.
2.5 Operational Limits
2.5.1 Centre of Gravity limits
Centre of gravity limits are not critical on the trike of a flex wing ultralight. Having the trike unit attached
to the wing with a hang bracket, variations of cockpit loading and fuel loading cannot influence the
ultralight’s balance. The ANT is therefore not critical in regards to centre of gravity although the
distribution of load in the trike has an affect on the in-flight attitude of the ultralight.
2.5.2 Maneuvering Limits
All aerobatic maneuvers including spinning are prohibited.
Aerobatic maneuvers including stalls, stalled spiral descents and negative G maneuvers are not
permitted. These maneuvers put the ultralight outside the pilot control and put both the ultralight and its
occupant in extreme danger.
Do not pitch nose up or nose down more than 45 degrees from the horizontal.
Do not make high speed abrupt turns.
