Assembly Line

Dynali helicopters are manufactured and fully assembled from A to Z in a single production site in Belgium. All mechanical parts are machined and welded in our factory. The Dynali 912 ULS-I-BB is based on a Rotax engine block to which Dynali has added its own injection system and an ECU entirely mapped by our engine specialists. Cylinders, pistons and other critical parts have been designed by Dynali to provide 135 hp and an engine fully adapted to helicopters.

Following assembly, the engine spends 5 hours on a test bed for break-in. All parameters are monitored during a normalized procedure. After this step, the assembly is finalized and the bodywork can be performed. This stage includes painting of the fairings in our paint shop equipped with a paint mixer and a chromograph. This allows the client to specify exactly the colour scheme desired. Finally, the helicopter is submitted to 5 hours of test flights covering the full flight envelope – then a quick wash and polish and it is ready for delivery to the lucky customer.

It is this integration of the production processes which enables Dynali to quote very short delivery times (around 120 working days).

A Highly Qualified Team

The company has 25 full-time employees working in a 4 000 sqm factory in Belgium. A large part of the personnel is employed on the production line. At the same time, a team of engineers works full-time on developing UAVs/drones designed to provide tailor-made solutions to customers’ requirements.

The concentration in a single production site of all the skill sets required for the manufacturing and assembly of helicopters, from engine preparation to avionics, provides Dynali with tight control over all processes and offers a guarantee of quality and short delivery schedules.

Our Process of Production

We invest in high-precision equipment for machining essential parts such as rotor and engine components. Our CNC machines enable the production of complex parts with strict tolerances, ensuring exceptional performance while complying with rigorous safety standards.

Our skilled welders use proven traditional techniques to perform high-quality welding. Thanks to their expertise and the use of premium materials, we ensure the strength and durability of every metal component. This process is crucial for guaranteeing the longevity and safety of the structures, relying on a fully mastered craftsmanship.

Painting is carried out with exceptional expertise in our in-house paint booth, located directly within our factory. This allows us to guarantee a flawless finish that meets each client’s requirements. We offer a wide range of colors and finishes, making it possible to customize every helicopter according to your preferences, while maintaining impeccable quality. Each layer of paint is applied with meticulous precision to ensure a refined and long-lasting appearance.

The engine is prepared by our engine specialist to deliver 135 hp from a 1600 cc displacement. It is equipped with an innovative injection system, specifically designed to meet the unique needs of our helicopters. The injection management has been carefully developed by our engineers to ensure optimal performance, increased reliability, and maximum efficiency during every flight.

 

The test bench phase involves testing each helicopter by simulating various flight conditions. This step verifies the proper functioning of all systems and ensures that the engine meets strict performance standards. It guarantees the safety, reliability, and optimal performance of the helicopter before delivery, confirming that it is ready to operate in real-world flight conditions.

Experienced pilots perform flight tests to assess the helicopter’s handling, stability, and safety in actual flight conditions. These tests allow for any necessary adjustments to be made and ensure a seamless flying experience. Each aircraft undergoes multiple flight tests before being delivered to our clients.

Maintenance & Operating Costs

The H3 Sport maintenance program is designed to ensure the safety and longevity of your aircraft, with inspections scheduled at 25, 50, 100, 300, 600, 1200, and 2000 flight hours. Some maintenance protocols are available in the documentation section of our website.

Direct & Operating Costs

The estimated maintenance cost, including parts and labor, is €75 (excl. VAT) per flight hour, calculated over a total of 2000 flight hours.

Calculation Method:
The estimate is based on all parts listed in the maintenance manuals and the associated labor time. The total cost for 2000 flight hours was then distributed evenly over each flight hour.

Total Operating Costs

  • Direct operating cost per flight hour: €75

  • Allowance for unscheduled repairs per flight hour: €5

  • Fuel consumption (22 L/h): €40

  • TBO (Time Between Overhaul) for the rotor: 1200 hours
  • Main Transmission Gearbox (BTP) and Rear Transmission Gearbox (BTA) are inspected every 300 hours
  • Engine overhaul required at 1200 hours
  • We offer several levels of maintenance training, tailored to the needs of each user.
  • Professional tooling is essential. Dynali has developed specific tools to simplify certain maintenance procedures. For more details, please refer to the maintenance protocol available on our website.

 

FAQ

Find the answers to all your questions about our helicopters. We also answer your questions about the drone.

Yes you need to. The kind of license will depend upon the applicable regulation in your country. In many countries, the Dynali H3 Sport is considered and certified as an “ultralight helicopter” and thus requires an ultralight helicopter pilot license. The process for obtaining such a license is relatively simple as compared with a “PPL/H” or private helicopter pilot license. In the countries where the helicopter is certified and registered as a kit-experimental helicopter, you will usually have to pass a PPL/H license.

Dynali sold nearly 1 000 fixed wing ultralight aircrafts before starting to develop helicopters. To-date over 200 Dynali helicopters have already been delivered in more than 14 countries, on 5 continents.

You can contact one of our distributors to ask for a quote. The H3 sport is the lowest cost side by side two-seater helicopter in the world thanks to investments made in our production line. All prices quoted by Dynali are ex-works and tax excluded.

Yes it does. Most of the theoretical topics are the same (weather, communication, …). Having some experience on fixed wing aircraft or gyroplane surely helps for the practical side as well, but flying a helicopter requires some more training as it is truly different.

No, Dynali does not provide flight training. However, Dynali has a network of flying schools in numerous countries and can help you get in contact with them.

One Dynali helicopter can be shipped in a standard container (20′), with just the removal of the main rotor blades and two blades from the tail rotor. Reassembly takes less than one hour.

Yes, everything is included to allow for legal and safe flight in VFR daylight conditions. Additional instrumentation, transponder, radio are among many options available. When the helicopter is delivered, all the assembly has been carefully inspected according to the complete control protocol. Five hours of flight tests and commissioning are performed before delivery.

Yes, with an H3 Sport, your instructor can certainly train you on your own machine.

Yes you can. The 25 h and 50 h maintenances can be performed without training. A maintenance training is required for the further maintenances. The formation can be completed at Dynali or one of our Distributors.

Our helicopters fly with SP 98 (unleaded 98 octane automobile fuel). Models produced from 2023 onwards can fly with or SP95, SP98 or Avgas 91UL (unleaded fuel developed for ultralight aircrafts). Please note that these recommendations are subject to updates by the factory.

It depends on the local regulation in your country, regarding ultralight helicopters. In Europe, the H3 Sport falls into the ultralight helicopter category which authorizes it.

Yes. Every Dynali helicopter undergoes ground tests and at least 5 hours testing through the full flight envelope by the company pilot before shipment.

Yes. Every Dynali helicopter is fitted with an accurate governor to maintain the constant rotor speed required for helicopter flight. The governor is fully automatic and does not require any action from the pilot during the flight.

This depends on the status of the order book at the time of placing of the order. The maximum delivery time is 6 months. However, it is only when the firm order and the 50% deposit have been received that an airframe number is allocated and a firm delivery date, which may be considerably shorter, can be confirmed. Usually, the delivery time rounds 4 months.

Dynali welcomes potential distributors and customers at its facility in Belgium. Access is fairly easy as Dynali is at mid-distance between the Brussels National Airport and Charleroi airport (Ryanair hub), and Dynali can provide airport pickups. Alternatively the company is 10 minutes from Nivelles station which is itself a 20 minute train ride from Brussels Midi station, from where Eurostar, Thalys and TGV high speed trains link Brussels to the rest of Europe. An aeroclub 5 km from Dynali welcomes visiting ultralight aircraft (Baisy-Thy/EBBY).

Extremely well. The helicopter’s rotor has been develop considering this important aspect. Thanks to its inertia and excellent flying capabilities and all those who have tried it have been impressed by its docility in autorotation.

For a competent aircraft mechanic it is extremely simple. For those among us who have no mechanical experience, it is probably safer, at least at first, to leave it to a professional who has a copy of the maintenance manual.

First just send an email to info@dynali.com and tell us a little about you and your operation. We will then contact you and send you a standard Dynali distributor contract and invite you to visit the factory, see the manufacturing processes and talk with all our key people. The main requirements for a distributor are to buy a demonstration machine, having a flight school, at least one pilot and one qualified technician trained on H3. If everything fits, for you and for us, we sign a distribution contract.
