A relatively smaller, modern helicopter with no more than five seating capacity and weighing less than 2,500 lbs (1,133kg) powered by a lightweight, fuel-efficient, and powerful piston (or reciprocating) engine comprising of four- or six-cylinders fuelled by Avgas (Aviation Gasoline).

The piston engine operates as follows:

First, the piston is drawn down into a cylinder by the crankshaft where the intake valve at the top of the cylinder opens, sucking in air and mixing it with fuel. The cylinder then rotates from the bottom back up in the cylinder where the intake valve closes, completely sealing the cylinder and compressing the fuel/air mix as the piston rises to the top. As the piston reaches the top of the cylinder, a sparkplug ignites the fuel/air mixture causing a tiny explosion rapidly expanding the increasing pressure that forces the piston back down in the cylinder. From the bottom of the cylinder the piston is then forced back up to the top of the cylinder. With the momentum of the crankshaft and the other cylinders firing, the exhaust valve opens to allow the dissipated gas to be discharged through the exhaust outlet, after which the exhaust valve then closes, ready for its next cycle.

The Robinson R44 Raven II is equipped with a Lycoming IO-540 (derated to 245hp for take-off and 205hp for continuous flight) six-cylinder, fuel injected engine for the four-seater helicopter with a Max Gross weight of 2,500lbs (1,134kg)

Enstrom Helicopters utilizes the robust Textron Lycoming IO-360F1-AD turbocharged engine delivering 225shp and 167kW to power their three-seater Enstrom 280FX and F28F model helicopters with a gross weight of 2,600lbs (1,179kg).

Powering the Schweizer 300CBi three-seater (utility certified) is the Textron Lycoming HIO-360-G1A engine with a 180shp rating and a 134kw output to lift the Maximum Take-Off Gross Weight of 1,750lbs (794kg)

Guimbal Helicopters opted for the Lycoming O-360 180 hp (derated to 145shp) engine to power the Cabri G2 two-seater helicopter weighing at a max gross of 1,5,43lbs (700kg). This engine is certified for the use of unleaded Avgas or unleaded automotive gasoline.

Leader in the helicopter training industry is the light-weight Robinson R22 Beta II weighing in at 1,370lbs (622kg) powered by the dependable Lycoming O-360, four-cylinder, carbureted engine that has been derated to 131hp for take-off and 124hp for continuous flight.

To answer this question, we have to consider that with turbine powered helicopters we are dealing with altitude pressure and temperature whereas with piston helicopters the power relies on the altitude density.

Piston engines are also known as reciprocating engines and are usually used in the smaller type helicopters, because they are cheaper to manufacture and maintain than turbine engines. The biggest difference is the result of atmospheric conditions on energy (power). In the piston engine the power available depends on the density of altitude and in the turbine engine the power available is dependent on pressure altitude and temperature.

In turbine engines, the air is sucked in through the air inlet before it enters the compressor. Most turbine engines are fitted with a particle separator that removes any foreign matter (sand/dust/tiny stones) that could cause damage to the compressor blades. As the air flows through the blades, it becomes more compressed, increasing the pressure and reducing its speed feeding the air into the combustion chamber. Fuel injectors inject atomized fuel into the combustion chamber where the air/fuel mixture is then ignited causing it to expand and forced through a series of turbine wheels, causing them to rotate. The spent fuel is then ejected from the engine through the exhaust system and released through the exhaust air outlet.

In most piston powered helicopters the pilot controls the engine rpm by means of the throttle on the collective. Power management in turbine helicopters is controlled through an electronic system more commonly known as FADEC (Full Authority Digital Engine Control) which controls the demand for power when collective changes occur.

Piston and turbine helicopters also use different fuels. Avgas (Aviation Gasoline) is mainly used in piston engines and is relatively inexpensive, whilst turbine engines consume JET-A1.

Turbine helicopters are also more expensive to maintain than piston helicopters.

In order to demonstrate the difference between piston and turbine helicopters, we shall be comparing Enstrom Helicopter’s F28F and 408B models.

The F28F is fitted with a Lycoming HIO-360-F1AD turbocharged engine and has a fuel capacity of 40 US Gallon (151l) and an estimated direct operating cost of $211 per hour. It measures in at a height of 2.7m (9.0ft) and width of 2.2m (7.3ft). With a seating capacity of up to three people, the F28F can reach a range of approximately 229nm (424km) and an endurance of around 3.5 hours.

Flagship 480B is fitted with a Rolls-Royce 250-C20W turbine engine and has a fuel capacity of 90 US Gallons (341l) and an estimated direct operating cost of $342 per hour. Standing taller than the F28F the 480B measures in at 3m (9.7ft) and is also slightly wider at 2.4m (8.0ft). The 400B seats up to five people, can reach a range of approximately 370nm (685km) and an endurance of around 4.7 hours

GAMA (General Aviation Manufacturers Association) released the figures of the new piston helicopter deliveries for the first quarter of 2022 in May, with Robinson taking the lead with the most deliveries of 36 units in total.

Robinson R44 Raven II (19 Units Sold)
The Robinson R44 Raven II has been the world’s best-selling general aviation helicopter since production started in 1992. The Robinson R44 Raven II is derived from the two seater Robinson R22, adding two additional seats, a more powerful Lycoming IO-540-AE1A5 fuel injected six cylinder engine and wider main rotor blades, improving altitude performance and increased gross weight.

Robinson R44 Raven I (12 Units Sold)
Significantly less expensive than the Robinson R44 Raven II, the Robinson R44 Raven I is fitted with a Carbureted Lycoming O-540 engine and although it offers a slightly diminished payload, it features carburetor heat assist which automatically adjusts carburetor heat, reducing pilot workload.

Robinson R44 Cadet (2 Units Sold)
With the same airframe, engine and rotor system, the Robinson R44 Cadet’s aft compartment has been refigured to accommodate cargo instead of people, the maximum gross weight has been reduced to 2,200lbs (997kg) and the engine power derated to 210hp on take-off and 185hp continuous.

Guimbal Helicopters Cabri G2 (3 units sold)
The brainchild of Bruno Guimbal (a former Eurocopter engineer) this two-seat light helicopter packs a big punch for such a small rotorcraft! The ground-breaking Guimbal Cabri G2 helicopter is the first piston-engine helicopter to feature a glass cockpit with an all-in-one digital flight display system and also the first to make use of the plasma ignition system. A storage compartment behind the cabin seats has a widow, providing for easy in-flight access.

The Guimbal Cabri G2 is powered by the Lycoming O-360 piston engine rated at 145hp (producing 108kW) at max continuous power and able to cruise at a speedy 90kts (166km/h) offering a range of up to 377nm (700km). Instead of the skids being directly bolted onto the fuselage, the Guimbal Cabri G2 utilizes elastomeric mounts providing greater articulation and reduction in ground resonance.

Robinson R22 Beta II (3 Units Sold)
Since production started on the Robinson R22 in 1979, this two seater helicopter has been domineering the helicopter training segment for over forty years! Known for its affordability, excellent performance and adaptability, the Robinson R22 Beta II is also used for livestock management and game capturing. The Robinson R22 Beta II is powered by a Lycoming O-360 engine that has been derated to 131hp for take-off and 124hp for continuous flight.

The Top five Piston Helicopters based on their altitude performance ranking from the lowest to the highest HIGE (Hover Into Ground Effect) and (Hover Out of Ground Effect).

1. Robinson R22 Beta II
   Powered by the Lycoming O-360 with a 180hp derated to 131hp, it has a MTOW of 1,375lbs/634kg, a HIGE of 9,400ft and HOGE of 7,500ft.

   Powered by the Lycoming O-360-J2A engine with a 145hp rating, it has a MTOW of 1,540lbs/700kg, a HIGE of 5,000ft and a HOGE of 3,500ft.

The feisty Guimbal Cabri G2 is the leader of the pack when it comes to range capability, reaching up to 377nm/700km. Travelling over such a distance quite comfortable due to the larger than usual cabin, constant airflow through ergonomic air vents and excellent visibility. The Guimbal Cabri G2 is a two seater side-by-side configurated helicopter that is powered by a Lycoming O-360-J2A piston engine.

Schweizer’s 300C utility/training helicopter fitted with Lycoming HIO-360-D1A has a range of 374nm/694km, making it the helicopter with the second farthest range. In training configuration, the rotorcraft has a seating capacity of two, while in the utility configuration the pilot can be accompanied by up to two passengers.

Third in line we find the trio of Robinson R44’s comprising of the Raven R44 Raven II, Raven R44 Raven I and R44 Cadet. Although powered by different Lycoming engines, all three helicopters have an approximate range of 300nm/550km. Mr. Frank Robinson knew what he was doing when he created this diversity of helicopters to cater to a multitude of missions.  With exception of the Robinson R44 Cadet (mainly used for training, being a two seater with additional space for cargo), the Robinson R44 Raven II and Raven I can seat a pilot and up to three passengers.

Fitted with a Lycoming HIO-360F1AD engine the Enstrom F28F comes in at fourth place with a range of 229nm/424km when operated at the excellent altitude of FL3,000ft (Flight Level) (with no reserve) it is mainly used for private use, helicopter pilot training, commercial and agricultural purposes and law enforcement.

Beating the Magni Gyro M24C ever so slightly (225nm/416km) for the last placement – but not the least on this list - is the Robinson R22 Beta II with a range of 250nm/463km. As one of the most reliable light helicopters with over forty years proven in operation, the Robinson R22 Beta II has stood the test of time.

The pricing of a pre-owned helicopter is dependent on the overall condition of the rotorcraft, maintenance history, damage history, additional equipment and avionics installed. New aircraft are priced at a Base Aircraft Price that does not include additional equipment, customized paint, interior, and additional avionics installed.

As the only four seater piston rotorcraft, it does not boggle one’s mind that the Robinson R44 is the one of the most expensive options available with a Base Aircraft Price of $465,000. Starting from nearly $530,00 for a low model, high-end option helicopter down to a low of $353,000

Second of the most expensive single piston helicopters in this world, the Schweizer 300C with its longstanding design, high safety record and reputation for extreme manoeuvrability, weighs in at an Aircraft Base Cost of approximately $463,000 which includes priced optional extras, with pre-owned options ranging from $138,000 for a late model 1970’s rotorcraft up to $493,000 for a recent model factory new option with most of the trimmings.

Considering that the Guimbal Cabri G2 features cutting edge technology such as the three blade fully articulated main rotor blades, Fenestron-type tail rotor, extensive safety adjustments and state-of-the-art all-encompassing glass cockpit display, the Base Aircraft Price of $395,000 (excluding optional equipment and avionics) is most certainly justified in second place! Pre-owned, the Guimbal Cabri G2 can be acquired from anywhere between $370,000 up to $400,000 with the latter being exceptionally spec’d out.

As the world’s most economical light helicopter, the Robinson R22 Beta II is offered at a Base Aircraft Price of as little as $314,000. For used Robinson R22 Beta II helicopters you can expect to fork out anything between $60,000 up but not limited to $324,000, depending on your needs and expenditure.

The Safari Helicopters RotorWay A600 does not disappoint in terms of acquisition costs. Offered as a kit to be assembled by the owner, a Base Aircraft Price of $150,000 is not understated if you consider that the new owner is not billed for any assembly hours. RotorWay does offer the option to purchase the aircraft in four stages, though. Used, there are no offerings available as of yet.
