The feeling of flying in absolute silence, listening only the sound of the wind is indescribable and causes jealousy in the pilots of every jet. To honor these unique air crafts, I chose to build a racing glider. This construction is made with some new elements that try to simulate the air elasticity of modern wings as well as the ballast system they incorporate.


The wings have five separate segments with variable dihedral from -0.5 to 4 degrees. Also as their thickness and width decrease as they are diverge from the fuselage, an original construction has been applied which gives smoother results. The plane have full span flapeons and a fully functional submersible spoiler system. Ailerons deflect -+10 degrees and flaps have -4 to 8 degrees movement.

To give the illusion of ballast rejection, the glider has a few gallons of fuel. When you want to extend your stay in the air you can activate the nozzles. As the fuel empties you will notice a visible aerosol line at the bottom of the vertical stabilizer. Unfortunately I could not hide the soft sound, but the result does not spoil the illusion as the machine does not produce impulse.

The tow aircraft is a very simple construction with minimal parts. Both planes share common controls, so to ensure that the tractor takes off at a synchronized speed and after taking off will not hit the glider, its wings have a fairly large wedge angle. Be careful as the carrier has GREATER LIFT, if left after takeoff without guidance, it will continue to rise and eventually will fall into a loss of support FIRST (pulling the glider in free fall). It is recommended immediately after take-off to keep a speed higher than 68 mph, with an ascent angle (AoA) not more than 10 degrees (at regular intervals keep your nose down)

In the cockpit there is a pilot that maintains a slight mobility when the controls are moving, and there is a speedometer, compass, vertical speed indicator and turn coordinator that is functional.

Vno=120, Vne=110, Vo=92, VR=60 Vs=36 VTd=45
Ag 1=Airbrakes (Spoilers)
Ag 2=Water Ballast system
Ag 4= Tow cable release

    The fact that you vectored the 'vapor trail' to match the angle of airflow, that's the kind of detail that amazes!

    @Wi1dSk7 Thank you very much for noticing, it has a lot of new information. Among them, the wings are made in a new way. The flaperons move in a cylinder like a real axis.They are also reduce in thickness along the length without gaps.

    @asteroidbook345 thanks for the vote and the spotlight. Did you like the airfoil aeroelasticity?
    @toxicgamer88 better late than never. But you know in one download you get two planes for free. Lol
