Pelican Polyhedral Wing Building Instructions

SPECIFICATIONS

Fuselage length 26" Polyhedral and Aileron wings are 34"

The Pelican is cut from 100% EPP foam

The fuselage is laminated but the wings are designed to not be laminated.

Center of Gravity: 2.75" (7 cm) back on the wing

Pod mount motor does not change the center of gravity

Elevator, Rudder and Aileron Throws: 3/8" up/down/left/right (1 cm)

Wing tip angle is up 3.5" to top of the wingtip on each side of the polyhedral wing.

Dowels back 5" and 13" from the nose of the fuselage

Motor pod is back 5" from the nose of the plane behind the front dowel

Motor has two 3/16" washers under bottom screw to get a positive motor angle

Use four to six #64 rubber bands to secure wing

2812 motor, 7x6 APC prop, 20A ESC, 2 mg90 servos,

1300 -1500 mah 3S lipo battery

Target All-Up Weight: 15-22 oz

Lighter always flies better!!!!

The aileron wing for the Pelican is a great variation of an old favorite. With the 2812 motor is a nimble and

exciting plane to fly. You can build it light for slow and stable flight or put a more powerful motor and

bigger battery on it for aerobatic flight with more throw on the flight surfaces. Watch the Pelican Build

Page 1 Lighter always flies better!!!! The aileron wing for the Pelican is a great variation of an old favorite. With the 2812 motor is a nimble and exciting plane to fly. You can build it light for slow and stable flight or put a more powerful motor and bigger battery on it for aerobatic flight with more throw on the flight surfaces.
Page 2 Mark the central spar location by lining up the tips with the main wing core. Lightly sand the carbon spar. Use a metal straight edge and a new razor blade and cut a 1/2" deep slit across the top of the middle core of the wing. Press the carbon fiber spar into place with the spar centered with the same amount of spar poking out of each side.
Page 3 Using the hot glue gun work several pumps of hot glue in the wingtip around the spar that is in the tip from both the top and the bottom. Make sure the wingtip is still 3.5" off the table while the glue cools. The aileron wing has a cut out in the center back of the wing that not only helps with ailerons but helps strengthen the back of the wing so it is less likely to tear with the rubber bands.
Page 4 Using a medium temperature hot glue gun glue on the nylon reinforcing braces to protect the foam from being torn by the rubber bands. This is the end of the stock wing build. Due to the number of flyers flying with bigger motors and FPV gear we are adding information on how to reinforce the wing tips.
