Did you say 4th generation?
Light aviation has evolved a lot since its inception more than a century ago. With the Elixir, we are stepping in a new era that lays the foundations of the future. This generation rhymes with the end of complex assemblies, illustrated by OneShot that removes rivets, glue and screws. Ribs and spars belong to the past! It allows improved safety, reduced costs and unmatched versatility.
What is OneShot?
OneShot is a technology that has been used in competitive sailing for more than 15 years. This technique consists in designing and manufacturing complex elements (such as a wing) without complex structural assemblies. For example, the Elixir wing is made without ribs or stringers. Traditional mechanical assemblies such as screws, rivets and glues are no longer required. Elixir Aircraft is the first company in the world to design a complete wing (the entire wingspan) entirely in OneShot. The fuselage, canopy arch and control surfaces (ailerons, flaps and daggerboard) are also made in OneShot.
Be careful not to confuse OneShot parts with monobloc parts. A OneShot part is necessarily monobloc, but the opposite is not true. A classic monobloc wing is a unique element from one end to the other but consists of hundreds of parts assembled together (spar, rib, skins, stiffeners...). A OneShot wing is monobloc from one wingtip to another but it has no longitudinal members and no ribs, it is a structure called a "box" structure without separately applied and glued elements.

Carbon fiber is hard to repair.
Even if broken in half, a composite part is still repairable. The operator will probably spend less time repairing a carbon fiber part than on a wooden or metallic one. Moreover, the repair will not leave any after-effects.If a part of your Elixir is damaged by an impact, no need to change it completely! Sand it, laminate it, paint a patch and you are done.
For 40 years, the majority of gliders have been made of composite materials and fly without any problems while being subject to more stress (field landings). For your information, we recommend viewing a very good video made by Grob on composite repairs.
A certified aircraft is expensive.
Not anymore! With the Elixir, flying on a CS-23 certified aircraft has never been so accessible. OneShot reduces the number of parts, and therefore maintenance costs.
The modern engine powering the Elixir also reduces fuel costs, thanks to reduced consumption (10-15L/h) and the use of cheaper auto fuel (E5).
In addition, the Elixir team designed an aircraft with maintenance in mind. Thus, for each maintenance operation, an access hatch and a straightforward procedure have been designed to reduce the number of maintenance operations. Less operations, fewer costs and more safety! 40€/h of fuel and maintenance, that's our goal!
EASA CS-23 type certificate, what for?
CS-23 certification is issued by the European Aviation Safety Agency (EASA). It ensures compliance with the safety regulations established by the latter. It concerns all aspects of the aircraft, whether its structure, powertrain or flight characteristics. This is a guarantee of safety but also of quality.
Without MTOW limit at 600kg or 750kg, without minimum stall speed, IFR-allowed... The EASA CS-23 now opens the doors to future evolutions of the Elixir, where other aircraft will be limited. Finally, the CS-23 certification will allow you to fly in almost any country in the world, without restriction.
Why a 2 seater and not a 4 seater?
The Elixir is a versatile aircraft, designed for training and travel. Statistics show that today’s aircraft are occupied 80% of the time by one or two people. High acquisition cost, more complex and expensive maintenance, higher fuel consumption. With the current use of aircraft in mind, a two-seater makes more sense to us
What about the environmental impact?
After 50 years of flying heavy aircraft, using fuel-consuming and environmentally unfriendly engines, light aviation must lead the way to energy transition. Elixir Aircraft offers a certified aircraft, 50% more fuel efficient than the vast majority of certified aircraft to date. With its Rotax 912iS (100HP), the Elixir uses unleaded gasoline that is less harmful to the environment and consumes only between 10 and 15L/h.
In addition, thanks to OneShot, the Elixir is lighter and has a greater carrying capacity. OneShot significantly reduces dust and solvent phases during production, further reducing its impact on the environment. For the future, Elixir Aircraft is carefully looking at the emergence of new engine technologies.
Why the T-tail?
In love with Michel Colomban's designs, the T-shaped tail is perfectly mastered by Elixir Aircraft. This configuration is easy to maintain, far from the wheel projection areas (ideal on grass strips) and allows you to recover from a spin in all circumstances, never masking the rudder.
What are the wing fences designed for?
Students, experienced pilots, pilots doing their minimum 12 hours... The Elixir is an aircraft that can be put in all hands. Nowadays, stalls during the last turn are still too common. Unfortunately, in the last turn, no matter how easy it is to recover from the spin, it is already too late.
Since the appearance of certifications, manufacturers have had to design aircraft that recover properly from spins. At Elixir Aircraft, we consider that this is not enough. We wanted to make sure that no matter the situation, the Elixir will stall safely and will remain steerable after the stall. The objective is to allow the pilot to flatten the wings in the event of a stall at the last turn and avoid any inversion of the pitch. This significantly increases the chances of getting out of it.
The "Fences" therefore play a major role. At high incidence before or during a stall, their role is to prevent the turbulent air flow from reaching the ailerons. Thanks to their association with the evolutive wing profile, aileron control remains effective during stall and allows you to recover from a worrying situation.
Why is there a keel?
The keel is present to ensure optimal stability at all speeds, from the stall to the Vne. Like the "Fences", it contributes to making the Elixir an aircraft that can be put in all hands
How are the hourly costs explained?
You regularly hear about 40-45€/h. This is our estimation of maintenance and fuel costs (E5) over 2,000 hours of use, up to the Rotax TBO. Thus, we estimate the maintenance cost at 40,000€, or 20€/h. On an average of 12.5L/h, we estimate that the fuel represents about 37,500€ at a cost of 1.5€/L.
The 70€/h corresponds to our rental offer, mainly for flying clubs. This amount is based on 360 flight hours per year (30 hours/month), which corresponds to the average number of hours flown by flying clubs (in France). This offer includes insurance and maintenance.
