Our 2008 range represents the latest in fuel efficient, quiet and powerful Paramotors, utilising our second generation state-of-the-art 4stroke engine, now available for the first time in a choice of two capacities, the 4stroke150 and the 4stroke175.

Our 'World First' 4 stroke paramotors have proved devastatingly effective over the last 3 years in competitions, with many UK, French and World Championship podium positions. Bailey Aviation machines are the leading choice for competition pilots, long XC pilots and fun-flyers alike.

The 4 stroke design provides a superbly linear power delivery, smooth from idle to the higher RPM limits, far removed from the peaky power delivery of some 2 stroke designs. Many pilots are enjoying the extra flying time our fuel-efficient 4 stroke design offers, with 4+ hours flights now possible from a 10 litre fuel load.

The 4stroke150 uses a 149cc (14.5HP) engine and the 4stroke175 uses a 178cc (18HP) engine. Both machines share the same core components, with the larger capacity 4stroke175 producing enough thrust even for 110kg pilots.

The Bailey 4 stroke is a single cylinder SOHC design and features CNC machined alloy crankcases, pressure compensating carburettor, stainless steel exhaust, oil cooler, Poly-V belt drive reduction, high power CDI ignition and electric starting system.

Our second-generation 4 stroke engine has a number of enhancements, including a new forced air cooling system, which consists of a carbon fibre outer cowling, concealing a crank driven fan assembly that forces cool air over the cylinder head, keeping temperatures down in even the highest ambient temperatures.

Enhanced cooling fins both internally and externally on the CNC machined crankcases further enhance the heat dissipation process and we have now fitted a smaller, more efficient fuel primer bulb. The electric starting system also features in flight re-charging with an auxiliary power output of 8 amps to drive flight computers or strobes.

The Bailey 4 Stroke engine is compact and weighs in at 19.3Kg with all ancillaries (but minus battery pack).

But are the 4 strokes heavier?
Many people are apprehensive at the dry weight of our 4 stroke paramotor compared to a 2 stroke counterpart, without understanding the affective advantages of the design. There are currently many 30kg + paramotors available, most having a fuel consumption of 4-6 litres / hour. This means that when fuelling for a 2-hour flight on such a machine it would require the loading of 10 litres (7.20kg) of fuel, bringing the total take-off weight to 37.20kg. A similar flight on a Bailey 4 Stroke that uses 2 litres/hour would only need 4 litres (2.88kg) of fuel, resulting in a take off weight of only 36.38kg. When contemplating the weight of a Bailey 4 Stroke, the fuel load has to be taken into consideration, as the 4 Stroke is very economical.

Notes

  1. Static thrust figures are measured on our own calibrated test rig and are averaged across a variety of different atmospheric conditions (temperature, pressure, humidity
  2. Fuel consumption figures are based on an 85Kg pilot with Action 27 wing on fast trim
  3. Noise level is measured to DULV (German regulating authority) standards, range 100 metres overhead, paramotor at wide open throttle

    TITANIUM CHASSIS AND CAGE SECTIONS
    New for 2008 is the TITANIUM range of chassis, cage quarters and hang-bars produced for Bailey Aviation by one of the worlds finest Titanium specialists. This exotic material is stronger and lighter than aluminium alloy (it has the highest strength-to-weight ratio of any metal) and possesses very high heat, corrosion and fatigue resistance. The outer hoop has been designed from aerofoil section Titanium for less drag and wind noise and has integral titanium loops for the nylon safety netting to be weaved through. The TITANIUM range has a weight saving of 1Kg from our standard aluminium alloy paramotors and give you looks second-to-none.

    Titanium has been used for many years in medical, military and aerospace applications and has a 'memory' and so can absorb minor impacts with little or no deformation. Chassis', cage quarters and hang bars are finished in natural titanium, complete with beautiful welding heat discolouration.

    Please note: Options and technical specification for the Titanium range are identical to that of our alloy paramotors, the only difference is the chassis, cage section and hang bar material. For full descriptions, please click here.
