Instruction Manual. FAIR CHILD PT 19. INTRODUCTION. Thank you for choosing the PT 19 ARTF by SEAGULL MODELS. The PT 19 was designed with the intermediate/advanced sport flyer in mind. It is a semi scale airplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood to make it stronger than the average ARTF, yet the design allows the aeroplane to be kept light. You will find that most of the work has been done for you already.

www.seagullmodels.com Remove the covering. Pen. 7) Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them using a modeling knife. 3) Put the stabilizer into place in the position of the fuselage. 4) Install the stabilizer onto the fuselage. Align the centerline drawn on the top and the rear of the stabilizer with the centre of the fuselage. When that is aligned, hold the stabilizer in that position using T-pins or masking tape.
Instruction Manual. FAIR CHILD PT 19. Remove covering. Fill epoxy. 2) While holding the vertical stabilizer firmly in place, use a pen and draw a line on each side of the vertical stabilizer where it meets the top of the fuselage. Fill epoxy. Fill epoxy. 10) After the epoxy has fully cured, remove the masking tape or T-pins used to hold the stabilizer in place. Carefully inspect the glue joints.
