ALBATROSS by CRASHTESTHOBBY.COM

 

The Albatross is a unique slow flyer designed to put its nose on the horizon and level its own wings without a pilot.  It is 
very quiet and designed to use inexpensive electronics.  It is one of my favorite night planes and small park flyers 
because it is quiet and easy to fly.  The fuselage is a strong solid block of EPP foam which increases its durability.  You 
will cut holes in the EPP fuselage to install your radio rather than installing electronics in a hollow fuselage.  We 
recommend you build your Albatross with a pod mounted motor because it protects the prop and motor and leaves room 
for a camera up front.  The Albatross is available with ailerons for more advanced flying and FPV but don't underestimate 
the stability and fun of the polyhedral wing.   

 

Instructions included for the front mount and pod motor and the polyhedral and aileron wing 

The optional pod mount and/or aileron wings do not change the CG location. 

Laminate included only for the fuselage.  The wing is NOT laminated. 

The aileron wing has the ailerons precut in the wing. 

Center of Gravity: 3.75” (9.5 cm) back on the wing. 

Elevator throws: 3/

8” (1 cm) up/down.  Rudder 1” (2.5 cm) left/right.  Ailerons: 3/8" up/down. 

On the polyhedral wing the wing 

tip angle is up 5” to top of the foam on each wingtip. 

On the polyhedral wing the rudder servo is plugged into the aileron plug on the receiver. 

The aileron wing has each wing tip up 2.5" on each wingtip or 5" up on one tip when the other wing is flat. 

Front wing dowel is 

back 9” from the nose of the fuselage. 

The back wing dowel is ½” behind the back of the wing. 

Use six to eight  #64 size rubber bands to secure the wing. 

Best flying weight: 19-27 oz (570-810 gm) Lighter always flies better!!! 

2812 motor, 25A ESC, 2 (or 4 for wing with ailerons) mg90 servos. 

1300 to 3000 mA 3S lipo battery recommended. 

Launch at 1/2 throttle and throttle up.
