Ultra light helicopter for sale

Ultralight helicopters have opened up the market to make helicopter flying accessible to many more people than the general aviation class for which both the purchase price and the operating costs are prohibitive to the general public.

The Dynali H3 Sport is an ultralight helicopter authorised in certain European countries under the ultralight helicopter category (MTOW 500 – 600 kg). The Dynali is certified for 500 kg and retains a comfortable reserve of power.

Incorporating a number of safety features generally found only on far more expensive aircraft in the general aviation class, the Dynali H3 Sport has been designed to meet the latest standards in the light aviation industry while retaining the simplicity of the airframe design and structural components.

The Dynali H3 Sport has an over-dimensioned steel airframe designed to provide maximum passive safety for the pilots. The complete main transmission of the H3 has also been deliberately over-dimensioned to handle over 250 HP, providing very wide safety margins.

On-site manufacturing of practically all mechanical parts and quality control of source materials complete the formula for a reliable helicopter in which owners can fly with confidence.

The H3 has been designed to provide easy accessibility to all the vital assemblies, thus providing for relative simplicity of maintenance for owners. The simplicity of maintenance provides a great advantage for owners.

The Dynali H3 Sport, has taken the market leadership as the two-seater microlight helicopter with the lowest cost, both to purchase and to operate and has proved its reliability in multiple roles, utilitarian, flight training and leisure.

The H3 is fitted with a 135 HP engine, based on the Rotax 900 series and modified by Dynali with an injection system and enlarged cylinders.

This helicopter is supplied in flyaway condition (or as a kit according to the regulations in the destination country).

Skids

The landing skids are very strong and can allow for very hard landings. Our ground tests allowed at 600ft/min impact with 1,5x the MTOW.... The skids are made from aluminium with stainless-steel sleeves which allow progressive deformation upon strong landing.

Airframe

The H3 has a monoblock tubular stainless-steel airframe: this is the principal structure to which all components are connected.... The airframe supports the engine and the mechanical parts. It directly underpins the seats and the cabin fairings. Where other light helicopters have a dangerous thickness of less than 1mm, the airframe of the H3 is designed for maximum passive safety with an average material thickness of 2,5mm in the tubular structure.

Cabin

Thanks to its 1,3m wide cabin, the H3 is the most spacious ultralight helicopter on the market. It allows two large people ... to sit comfortably and easily in the cabin, with plenty of elbow room, giving a feeling of space, while providing a panoramic view.

Rotor mast

The rotor mast is made of Cr-Mo steel and designed to bear a load of +22G.

Rotor head

The main rotor consists of two blades articulated in pitch. The teetering hinge rotor allows for great flexibility in use and... allows for tighter turns than most similar machines. The rotor blades are either in extruded aluminium or (optionally) in carbon composite. Aluminium provides the best resistance in poor weather conditions while carbon blade provides an extended lifetime.

Engine

The H3 Sport is powered by a 4 stroke Rotax flat four engine with injection system and big bore cylinders.

Main transmission

The main transmission gearbox transfers the rotating movement from the main transmission shaft to the main rotor mast.... The MTG of the H3 is dimensioned to support 250 HP whereas in reality it only has to bear a maximum of 135 HP. The gearings are fabricated from aviation quality steel which is thermally treated and lubricated in a mineral oil bath.

Stabilisers

The horizontal stabiliser provides excellent pitch stability. The vertical stabilisers are oriented 4° in relation to the longitudinal axis... of the helicopter. They compensate for the rotor torque by their aerodynamic effect. Thus the pilot does not need to use the rear rotor permanently. In the unlikely event of engine failure, the pilot can easily keep his heading by simply maintaining forward speed until flare.

Radiator

The coolant radiator of the H3 is a very important item for training schools. It is very large and allows for the H3 to be flown in hover for long periods... without over-heating, without requirement for periodic circuits to cool the engine oil. One (or two for hot climates) oil radiators are positioned on the coolant radiator and provide the same high efficiency performance. Two large fans, equipped with thermo switches allow for the automatic independent regulation of coolant and oil temperatures at ideal levels.

Governor

The governor acts as a « cruise control » and allows the pilot to avoid having to constantly adjust the throttle to maintain engine... and rotor RPM. The governor is a standard equipment on the H3.

Cyclic

The cyclic pitch control on the H3 provides both for easy access to the cabin and for comfort in piloting as there is no column between... the legs. On the passenger side it can be folded away when the machine is not being used for training.

Clutch

The clutch system of the H3 is commanded from the cockpit. It serves to connect or disconnect the engine to the transmission system.... When disconnected, it allows the engine to start with the rotor stationary, ensuring the safety of those on the ground during warm-up. Once ready for take-off, the rotor is engaged by the pilot using a switch on the instrument panel.

Storage

Storage lockers are provided for personal effects and documents beneath the cabin seats.
