Maxa wing spar

1 – flanges hot cured from carbon pre-preg in an autoclave;

2 – outer balsa webbing at 45 degree bias;

3 – Spread Tow carbon of ±45 degree layup totaling 0,04 mm in thickness;

4 – inner balsa webbing at 45 degree bias.

Maxa’s wing spar is cured at high temperature under vacuum. The spar flanges made in an autoclave from high strength carbon pre-preg are securely glued to the multi-layer web. We use high strength carbon fiber IMS 65 for the flanges.

The spar durability is improved by the use of balsa shear web. Balsa is more durable than any other material in this role. Placing balsa at ±45 degree bias not only improves it ability to carry shear load, but also improves the strength of the glue joint between the web and the flanges.

Additional layers of Spread Tow carbon improve the stiffness of the wing spar.

We build spars with two flange sizes:

- 11,5 mm wide;

- 10,5 mm wide (lighter spar).

The XXI century design from Vladimir’s Model employs Rohacell for flap core, which results in amazingly lightweight thin wings of surprisingly high strength. Combination of high aileron stiffness and low weight eliminates flatter even at the highest flight speeds.

To build wing for Maxa, we use bi-axial carbon Spread Tow fabric of our own proprietary design and production, made of high strength IMS65 carbon fibers. The weight of this fabric is 38…40 gram/m², which leads to lighter and stronger parts.

Maxa Spread central wing section

1 – Outer layers of our carbon spread tow laid at ±30 degree bias. Such layup results in high torsional stiffness and, at the same time, works in bending together with the spar. Outer Spread Tow layers improve the wing durability;
2 – Herex core of the composite sandwich;
3 – inner layers of thin Kevlar fabric at 45 degree bias;
4 – Spar flanges from high strength IMS65 carbon fiber, 10.5 mm wide;
5 – Rohacell flap core;
6 – The front wall of the aileron is made of balsa plywood covered with glass fabric. This design reduces the weight of the control surface, while its height together with Spread Tow outer layers results in unsurpassed torsional stiffness;
7 – strip of the hinge material;
8 – the rear wall of the wing from balsa plywood and fiberglass.

Maxa Hard Spread central wing section

1 – Outer layers of our carbon spread tow laid at ±30 degree bias. Such layup results in high torsional stiffness and, at the same time, works in bending together with the spar. Outer Spread Tow layers improve the wing durability;
2 – Herex core of the composite sandwich;
3 – Inner layers of our carbon spread tow laid at ±30 degree bias;
4 – Spar flanges from high strength IMS65 carbon fiber, 11.5 mm wide;
5 – Rohacell flap core;

Advantages of the ultra-stiff Maxa fuselage:

- The fuselage is attached to the bottom of the wing with 4 screws to facilitate the assembly—you don’t need to turn the plane over, after you plug the wing servo connectors.

- The wing structure is tied together with special shape nut, which is glued through the whole thickness of the wing. Such design better spreads shock loads of hard landings.

- The sharp nose stops the glider at the landing target. The shape of the tip meets F3J requirements.

- The tilt junction the tail boom with nose, in addition to the elegant appearance, greatly reduces the stress concentration at this location;

- Maxa ships with the completely assembled pod with tow hook and ballast tube already installed. The tail boom has the pushrod sleeves already installed and the vertical stabilizer glued on. You only need to glue the pod and the boom together.

- The Adjustable Tow Hook allows for launch optimization for any weather or C.G. location in the recommended range;

- Fuselage servos are installed horizontally, which allows for easy access to the receiver and the battery (see more on the manual bookmark).

- The front part of the nose is radio transparent made out of kevlar and high modulus fiberglass. You can place an antenna of 2,4 GHz receiver inside the nose (to the end of the canopy).

Tail boom

The Tail Boom is made from thin carbon Spread Tow laid at +45 degree (1) and -45 degree (2) bias. Between the Spread Tow layers, there are 2 layers of unidirectional high strength carbon fiber (3). This design yields stronger, stiffer, and more thermal stable tail boom, which weighs only 41 gram without pushrods.

Canopy

Canopy is made of carbon composite. . It uses reliable mounting latch design proven in many Vladimir’s Model planes: Supra PRO, Supra Electric, Blaster 2 Electric, Sprite, Graphite 2 Electric.

By numerous requests, we made Maxa’s tail of classical X-shape design.

We managed to overcome inherent drawbacks of this design and the resulting aerodynamic gains became apparent.

The horizontal stabilizer is now located higher up, which increases the launch safety.

The new design together with Vladimir’s Model trademark D-box built-up tail structure reduce the weight and increased the stiffness of the whole control system.

Vertical stabilizer

The tall and stiff vertical stabilizer gives Maxa good yaw stability and control even at low flight speeds. The horizontal stabilizer doesn’t shadow the rudder, which improves its efficiency.

The light built-up rudder can be taken off to reduce the fuselage length for ease of transport, this requires removing only one screw at the bottom. The screw with precisely ground stem slides into the bearing, which contributes to the accuracy and the stiffness of the yaw control, which is crucial for high energy launches. The composite tube serves as the rudder spar, which results in its extremely high torsional stiffness.

Horizontal stabilizer

Well balanced and light rotating horizontal stabilizer provides the required pitch stability. Its weight together with the joiner is 36 gram.

We have beefed up the horizontal stabilizer’s pivot, which resulted in substantial stiffness increase of the whole control system. The elevator pushrod is under tension, then you push the elevator up, which results in more precise elevator control.

Excellent control at low speed is achieved with the help of larger horizontal stabilizer area, which results in more accurate landings.

Our advanced CAD/CAM design and manufacturing yield unmatched accuracy of all the parts.

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;

Location-tail servos in the nose will significantly reduce the inertia of the fuselage. This significantly improved the control model at zero speed when landing;

- 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 3.5 EL

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 4 EL

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

This glider has no competition in the absence of lift in the morning or in the evening.

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

Unique aerodynamic properties and increased airframe stiffness result in very high launch speeds despite large wins span.

Maxa 4 EL climbs with confidence, when everybody else complaints about lack of lift.

The use of our proprietary, made in-house, high strength Spread Tow carbon laminates resulted in a glider with world lowest wing loading.

Wide selection of colors allows you to customize your model to reflect your unique style.

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