This is a super simple toy glider plane with adjustable flaps for fun in any weather!

It flies extremely well, is very light and easy to print, and very durable! 

Few things to note:

1. Before first flight, flaps should be adjusted to point slightly upwards. 
   When thrown, this setting will force air upwards and push down on the wing, balancing the load from the nose.

   

    

2. Below the best way (i have found) to hold the plane when throwing:

   

   Throw the plane the way you would a paper plane, focusing on keep it flat and lofted.

   
   (If you have an open air area, try to throw it vertically upwards! It should steady itself and glide slowly downwards)

    

3. For enhanced stability, make the tail wings into a “Y” shape. This allows the airflow at the rear to hold the plane stable in its yaw (tilt from side to side)

   

    

That's it! 
Play around with the settings of the flaps, angle of the tail wings and share your adventures!
