Maxa Ultra Light El wing spar

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

2 - сarbon spar walls with +45°;-45° degree bias ;

3 - carbon tubing of ±45° layup improves the torsional stiffness of the spar;

4 - the core is made from high strength foam;

5 - The wall of wing spar from Rohacell.

Maxa Pro El 3.5m and Maxa 4m Ultra Light central wing section 

1 – Outer layers of SC 26 2/45 at +45°;-45° degree bias;
2 – Herex core of the composite sandwich;
3 – Inner layers of SC 26 2/45 at -45°;+45° degree bias;
4 – Spar flanges from high strength IMS65 carbon fiber, 9.5 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 Rohacell with SC 39 2/45.

Maxa wing spar

1,7 – 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 3.5m and Maxa 4m Windy central wing section

2 – Herex core of the composite sandwich;
3 – Inner layers of SC 59 3/45,0 at -45°;+45°;0° degree bias;
4 – Spar flanges from high strength IMS65 carbon fiber, 15 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 Rohacell with SC 39 2/45.

Maxa 3.5m and Maxa 4m Light central wing section 

1 – Outer layers of SC 39 2/45 at ±45 degree bias;

Wing joiners

      During flights of Maxa 4 with standard 5-degree wing joiners it was noticed that the model is very inert while maneuvering.

After flight testing of the model with different tip dihedral angles, we managed to find the angle, at which Maxa 4 ceased to be inert, was well controlled by rudder, but the model was not overmuch stable and “dense” on the course.

Obtained additional rolling stability makes model more secure when flying at a great distance.Maxa 4 with 7-degree wing joiners is now similar to Maxa 3.5 or Supra as for easiness of control.Now the Maxa 4 kit includes two sets of wing joiners with an angle of 5 and 7 degrees.You could also purchase wing joiners with an angle of 7 degrees for your Maxa 4.

Advantages of the ultra-stiff Maxa Pro El 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 tilt fitting of the tail boom with the pod, in addition to the elegant appearance, greatly reduces the stress concentration at this location;

 - Maxa Pro El is supplied with pre-assembled fuselage of two parts.The tail boom is assembled with the stabilizer pylon and pushrods is already installed .You just need to paste the boom by epoxy resin.

Maxa Pro EL tail servos are placed on the board under the wing. There is also a possibility of accommodation servos in the canopy area (that is why rods is  so long in the tail boom). Servo board has additional servo horn supportwith bearing. More information about installing the servos,is in the instructions.

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.
