E-flite PT-19 ARF Assembly Manual

Using the Manual

This manual is divided into sections to help make 

assembly easier to understand, and to provide breaks 

between each major section. In addition, check boxes 

have been placed next to each step to keep track 

of its completion. Steps with a single circle (

) are 

performed once, while steps with two circles (

 

indicate that the step will require repeating, such as for 

a right or left wing panel, two servos, etc.

Remember to take your time and follow the directions.

Introduction

During WWII, the PT-19 Cornell was one of the 

primary training aircraft for the Army Air Corps. The 

PT-19 had a higher wing loading and higher stall 

speed that helped pilots in training learn more than the 

current biplane trainers.

E-flite’s version of the PT-19 is a scale, almost-ready-

to-fly, electric model designed for radio control with 

the option of control line. It’s 90% pre-built out of the 

box and boasts an appealing USAAC trim scheme for 

a great scale appearance. Those modelers who enjoy 

radio controlled flying can complete this ARF with the 

recommended E-flite

®

 Park 450 or high-powered Park 

480 motor. The PT-19 features an easily accessible 

magnetic battery hatch and steerable tail wheel for 

improved ground handling.

The PT-19 can also be flown as a control line plane. 

All of the internal control line completion hardware is 

included, while the ESC timer, wooden control handle 

and spool of wire cable is available separately. 

Control line flying will allow the airplane to be flown 

by two cables that connect the model to the operator 

through the optional control line handle and allow the 

operator’s hand movement to guide the model.

Either way you choose, the flying options are yours 

with the E-flite PT-19.
