We believe that you should wait until after your course before you decide to purchase your machine and wing as you will make a much better and more informed choice after talking with your Instructors.  In fact, we often have to tell pilots who buy their equipment first, that the equipment they have bought is either unsuitable, the wrong size or dangerous.

Although you can still use most Paragliding-specific wings with a Paramotor, you should ensure that they have the manufacturers endorsement as suitable for use under power and that the combined weight of the pilot, wing and power unit should be within the placarded weight ranges.  

At Mahony Aviation, we have a range of Paramotor-specific wings such as the fantastic Dudek Synthesis and some hybrid Paramotor wings that are both stable and fast under power but which will also free-fly very well - such as the new Ozone Roadster wings.  

PLEASE NOTE:

You should be aware that our Instructors at Mahony Aviation will do everything possible to minimise risk during your training, which includes injury to yourself and damage to our equipment. However these risks can not be negated completely and students / pilots alike who train / fly with us are strongly advised to take out Personal Accident Insurance to cover the risks - not forgetting to inform their insurers of the activity being undertaken.

Furthermore, students / pilots will be asked to provide a Paypal or cash deposit and sign a proforma at the beginning of their training / flying stating that they agree to pay for any damage to any equipment that they are responsible for whilst training / flying and belonging to Mahony Aviation.

4-Stroke Paramotors

We are proud to be a Dealer for the Bailey Aviation range of 4-stroke Paramotors.

British-based Bailey Aviation has been producing what many people believe are the best designed and constructed paramotors in the world.  Recently, Bailey Aviation turned their attention to the 4-stroke engine and they are now the only producers of 4-stroke engined Paramotors in the world.

Take it from us that when you have flown a Bailey 4-stroke machine, it is unlikely that you will ever want to go back to your smelly, noisy, oily two-stroke days!  If you would like to test fly a Bailey 4-stroke and you hold a BHPA or BMAA SPHG ticket, we can arrange a test demo for you before you buy!  Please contact us for details.

All About Bailey Paramotors

ENGINE HISTORY

The Bailey Aviation 4-Stroke engine was bourn from a simple idea – A compact, lightweight engine to revolutionise the world of paramotors and ultralight’s, providing an alternative to the run-of-the-mill 2-Strokes that have dominated the industry for the past 20 years or more.

Paul Bailey’s vision was to develop the 4-Stroke way beyond any previous attempts, massively reducing weight and size, increasing thrust output, all whilst keeping the engine’s operational stability and temperatures well within his design brief.

The results are world class engines that are smooth and linear from idle right up to the redline. They set new standards in fuel efficiency, are amazingly quiet and have no need for messy oil / fuel mixing. Above all, this engine has proved reliable and flexible, as proved by its countless competition wins around the globe.
Initial development of the 4-Stroke project started in 2003 and the prototype was flown successfully by Paul Bailey at the World Paramotor Championships the same year, with much interest from pilots and other manufacturers. This 125cc prototype was relatively heavy and underpowered but the combination of a 25cc capacity increase, substantial lightening of various parts and the re-working of some of the core engine components yielded big power gains. And so the production of the Bailey 4-Stroke 150 engine was introduced in Mk1 guise with 14.5 HP.

The production 4-Stroke 150 was a strong and confident performer, showing the world that the 4-Stroke vision was indeed now reality, successfully winning the UK and French 2004 paramotor championships and winning the best overall paramotor at the prestigious Sun & Fun exhibition in the USA the same year. The engine was produced with manual or electric starting systems and become a firm favourite with competition pilots and pilots wishing to push the envelope of long distance flights. With the amazing fuel consumption of the 4-Stroke 150, over 250 Kms was now possible with a 10 litre fuel load.
Introduction of the Mk2 4-Stroke started in 2006 with improvements made to the engine’s internal and external cooling fins, reduction drive mounting, the addition of a simple air cooling system and a new design of faceplate.

2007 saw the introduction of the 4-Stroke 150’s bigger brother, the 4-Stroke 175 which produces 18 HP (24% more power than the 150cc unit), along with revised carburetion / exhaust and the switch to electric only starting, allowing the addition of our new Forced Air Cooling System. The Forced Air Cooling System is manufactured from carbon fibre and is a shroud that fits around the engine mount side of the power unit and utilises a lightweight, high air-flow fan that is crankshaft driven to provide additional cooling over the cylinder head, thus reducing CHT temperatures.
2009 sees the introduction of our latest two 4-Stroke engines, the V3-180 (180cc 2 valve / 18 HP) and 4V-200 (200cc 4 valve / 22 HP). The release of our new engines opens up a world of possibilities for customers with paramotors or ultralights who previously only had the option of installing 2-Stroke engines in their projects. The fuel efficiency, compact dimensions and flexible mounting system of the V3-180 and 4V-200 engines are making many pilots’ dreams a reality.

ENGINE DESCRIPTION
The Bailey Aviation V3-180 is an aviation engine designed to power ultra-light aircraft, hang gliders, paramotors, trikes and any other aircraft that requires an auxiliary power unit. As the first and only dedicated small capacity 4-Stroke aviation engine, it is ideally suited for use in lightweight solo applications due to its exceptional fuel consumption, low noise, reliability and flexibility.

The engine is an air-cooled 4-Stroke single cylinder SOHC unit designed and manufactured in the UK by Bailey Aviation with a capacity of 180cc and producing 18 HP at 8000 rpm. The engine is smooth and linear in its power progression offering much improved NVH (noise, vibration, harshness) levels over a similar 2-Stroke counterpart. The engine was designed from the outset to be used in either pull (traction) or push conditions, offering high versatility in its mounting and operation.

The SOHC Bailey 4-Stroke has bespoke CNC machined 6082-T6 alloy crankcases with integral reduction drive support and four widely spaced engine mounts to reduce torque affect and offer maximum engine support. There is a single engine breather from the cam cover that must be vented to atmosphere.
Reduction is by lightweight 6082-T6 pulleys featuring a Poly-V belt system with integral eccentric adjustment for belt tension. A number of different reduction drive ratios are available to match alternative propellers designs and sizes.

A gravity-fed, pulse type mechanical fuel pump is used, with integral one-way valve which is mated to a very small and neat fuel primer bulb to prime the fuel system. The pressure-compensating carburettor is a float bowl design and has been chosen as it offers un-paralleled AFR (Air-Fuel Ratio) which is optimised all the way from Idle (3000 RPM) to its maximum continuous revs (8000 RPM).

The high-powered Capacitive Discharge Ignition (CDI) system utilises an electronic flywheel magneto and alternator (with 8 amp output) offering in-flight charging of the attached 12 volt batteries. The robust starter motor is powered by a separate starter solenoid and our shielded wiring harness contains all the connections required to run to dedicated start and stop buttons via a master switch.

All V3-180 engines are fitted with our Forced Air Cooling System which is manufactured from carbon fibre. The Forced Air Cooling System is a shroud that fits around the engine mount side of the power unit and utilises a lightweight, high air-flow fan that is crankshaft driven to provide additional cooling over the cylinder head thus reducing CHT temperatures.
