Maxa EL first glider designed by the concept of the new rules in 2011 FAI F5J.


- Aerodynamic quality glider enhanced by a comprehensive elaboration of the model parameters Joe Wurts. Therefore, the Maxa give odds in the absence of thermals in the morning or evening;


- Maxa is very sensitive to even small bubbles due to very low mass and low inertia especially consoles and fuselage;


Despite the large-scale Maxa has very little wind resistance and is very lightweight, so easy enough for the power plant is almost vertical take-off;


- Penetration, the ability of the glider to return from distant thermals without loosing much altitude, is improved by the exceptional aerodynamic properties of the new model;


- Ability to position ballast in the nose make it very easy to Maxa able to win in the strongest wind.



This combination of state of the art aerodynamics, low weight, and a good size makes the Maxa 4 the best model for competitive F3J soaring, bar none. See this RCGroups Maxa discussion and the Vladimir's Models Maxa 4 page for a lot more info.

Maxa EL first glider designed by the concept of the new rules in 2011 FAI F5J.

The main feature of such rules is the need to find thermals at low altitude and fly all 15 minutes in the final. Eliminated the need for high-power heavy motors. Therefore, the design we did not expect a quick empyrean rise, and rely on the performance characteristics of a glider:

- Aerodynamic quality glider enhanced by a comprehensive elaboration of the model parameters Joe Wurts. Therefore, the Maxa give odds in the absence of thermals in the morning or evening;

- Maxa is very sensitive to even small bubbles due to very low mass and low inertia especially consoles and fuselage;

Despite the large-scale Maxa has very little wind resistance and is very lightweight, so easy enough for the power plant is almost vertical take-off;

- Penetration, the ability of the glider to return from distant thermals without loosing much altitude, is improved by the exceptional aerodynamic properties of the new model;

- Ability to position ballast in the nose make it very easy to Maxa able to win in the strongest wind.

In the equipment, note the weight of the model and its rate of climb. This will allow you to choose the appropriate model of the tasks that you want to perform.

Choosing a model for a quiet and slightly thermal weather stop at Maxa 4 EL. With gross weight 1800 grams, you will receive a unique glider with huge opportunities to win the competition at the highest level.

For complex wind weather stop your choice on Maxa 3.5 EL. Due to its high maneuverability and a smaller scale with a high speed take-off, you get a glider able to find the flow in bad weather conditions, fly it away in the wind and go back to the site. Not of such a model, you dream before! Now it has become possible Maxa.


Maxa EL 3.5m 

 Maxa 3.5 EL is the universal soaring leader for any weather.

This glider takes advantage of even the weakest morning thermals, thanks to its light weight. High structural stiffness and novel aerodynamics allow Маха 3.5 to easily climb and return from distant thermals even in the windy weather.

Efficient wing mechanization permits accurate control of the flight speed not only on landing, but also during the search for thermals.

Increased area of the light horizontal stabilizer improves the control and guarantees “bull eye” landings.


Maxa EL 4m

 Maxa 4 EL –  a version with the wing span increased to 3,925 meters.

Maximum wingspan (according to 2011 FAI F5J) gives significant advantage in reducing the load on the wing.

In the wind, you return very lightweight glider from far flow at low altitude, while competitors were left in the field. This is Маха EL 4m !

Increased wing span also makes it easier to see the plane from a distance.

MAXA Wing allows you to effectively control the speed on landing, as well as to reduce resistance at take-off and switching between flows.

In addition, the increase in the concavity of wing is extremely effectively for the treatment of weak thermals.

Location of servos in Kiel leaves more space in the fuselage for higher capacity batteries.


Maxa EL 4m F5j Long tail

       Maxa EL 4m Long – the newest version with wingspan 3.925m. 

Tail servos are installed in the nose of the model. This significantly reduces the inertia of the fuselage and positively affects the quality of the flight.

The main advantage of long booms is to improve longitudinal stability of the model.

Hypersensitivity to flows, improved handling model, especially on small landing speeds (this also make more accurate landing), will allow you to fully realize themselves, and enjoy the flight.

We recommend you to use HYPER SPINNER POWER 32 mm for all versions of Maxa EL.

You can select the version, which best fits your needs, using the following table.
