E-flite PT-19 ARF Assembly Manual

MANEUVERING

Just for refreshers, we want to demonstrate the correct 

control technique for control line flying. You will want 

to hold the handle straight out from your body and 

give control input by moving your arm up and down. 

Very slight wrist movements will come into play, but the 

major control part is by full arm movement.

To fly level keep your arm straight and horizontal.

Neutral

To climb, move your arm upward which will cause the 

elevator to give an up command to the model.

Up

To descend, move your arm downward which will 

cause the elevator to give a down command to the 

model.

Down

TAKEOFF

With your helper holding the model and the battery 

hatch removed, position the plane where the wind is 

at the tail of the model for takeoff. Plug the battery 

in and wait for the speed control to initialize. Once 

complete, have your helper/holder push the button 

down on the timer to set the run time for the flight. 

Once set, your helper will install the hatch and you are 

ready for takeoff. Have your helper hold the model 

with the nose pointed slightly outside of the circle. The 

pilot should be ready to step back to maintain line 

tension immediately following release. Once the model 

is rolling along, apply a small amount of up elevator to 

have the model rise from the ground. Once in the air, 

level off at an altitude of 6–15 feet above the ground. 

As you fly, try some simple up and down commands to 

get used to your PT-19.

Flight Path

FLYING

During the flight you may wish to perform some basic 

aerobatic maneuvers. Using a combination of your 

straight arm technique as described earlier and very 

small wrist movements, you can begin your maneuvers. 

Practice and try one maneuver at a time. Ensure you 

place all maneuvers with the wind at your back to 

maintain line tension. If during any time of the flight 

you notice a decrease in pull from the model, this is 

an indication of reduced line tension and the pilot 

must step back immediately to regain tension. Failure 

to do so may cause you to lose control of your model 

possibly resulting in a crash and damage to the model.

LANDING

When the timer is at the end of the flight cycle it will 

cycle power very quickly to let you know you have 

less than 20 seconds until it shuts down. Once this 

occurs, you will want to position the aircraft to a level 

flight position approximately 6–10 feet above the 

ground. As the motor slows down, gradually descend 

to touchdown. Keep in mind the line tension is very 

important during this phase of flight. If the model is 

flying into the wind (or with the wind in your face) 

you may need to step back quickly to maintain line 

tension until touchdown. Once you have landed, have 

your helper pick up the model and take it back to your 

takeoff spot. During this time, try to keep the lines 

taut so not to snag them on the ground and cause 

any kinks which could fail at a later time. Unplug the 

battery and you have completed your flight. 

This is where it all started over 75 years ago in the 

world of model aviation. If you grew up with a blue 

and yellow PT-19 as most of us did, we believe this 

model should help you relive some of those great 

memories of yesteryear. We hope you enjoy the PT-19 

in both Radio Control and Control Line format as much 

as we do.

Happy flying!

FIRST FLIGHTS

Remember, it does not take large movements to fly 

a control line airplane. For the first couple of flights, 

concentrate on keeping your wrist and forearm locked 

into a position and move your hand up and down 

at the elbow. This will provide the needed amount 

of control movement while stabilizing the airplane 

and leading to a very successful flight. If you start 

by moving your wrist up and down, the airplane will 

respond very rapidly and it could result in damage. 

Take your time and relearn the skills you used to have 

… and you’ll have a blast again!
