NRJ 1.5m DLG F3K

Reaching the excellence in a DLG concept is for our actual times very difficult. Our goal was to put in the project all the best choices for aerodynamics, handling and flight abilities using the actual best technology and building skills.

The NRJ F3K characteristics are :
19 dm², Aspect ratio of 11.9 , 150mm root chord and an average chord of 130mm. This allows a good cruise speed and a a good L/D. The main difficulty about this type of design is to keep the wing performance at slow speed and High AOA. The wing has been developed specifically to address this issue. 

The airfoil series is going from 6% to 5.2%, keeping a reasonable camber and a good elliptical lift management along the wingspan (without tip twisting ) .

Chris made the choice to keep good acceleration characteristics and the average momentum of wing reasonably low and smooth to give to the model an easy speed-changing and a global ease, very appreciated in uncertain flight situations.

The good dihedral allows small inputs on the radio sticks to keep the circle while thermalling, with the minimum drag.
 The special tip shapes mark a different style during flight and to make the model more recognizable.


Launch abilities are superb, our small 4 in nose thin fuselage will help in low drag and speed flight modes.

The RTF weight would start from 190 gr for light version, giving the possibilities of great minimum sink rate flights, 210 gr for the standard version, (Textreme 60gr) and to something like 230 gr for the strongest layup.
The NRJ is a very “hands off” flying aircraft, with excellent L/D, and exceptional stability at lower speeds. 

The NRJ features a unique 3D printed "4 in the pod" servo mount that is included with each kit. The NRJ comes with servo trays for the MKS 75k. Available layups are:
Light-cw20 or cw30 spread tow
 Standard-cw40 spread tow,
 Strong-cw60 or textreme 60. All models are solid cnc foam core wings and tails featuring - CASCELL® IH
