E-flite’s AT-6 25e ARF is a superb scale replica of the legendary “Texan” trainer used by the U.S.—and its allies—from WWII through the late 1960s. It features a level of scale detail that is exceptional for an ARF of this size. You get all this realism without having to spend weeks of building, covering and painting. Just about everything has been done for you before you even open the box. All that’s left to do is a few hours of final assembly and radio installation. When you’re done, you’ll have a fantastic flying, scale warbird your friends will swear you scratch-built yourself.
Platinum Series Statement
Our Platinum Series delivers superior, enhanced features and meticulous attention to detail. The symbol on this kit is your assurance of excellence and one more way that E-flite brings you the most advanced electric flight experience.
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 each step completed. 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.

Notes Regarding Servos and ESC
WARNING: Use of servos other than those we recommend may overload the BEC of the recommended Electronic Speed Control (ESC). We suggest the use of only the servos we recommend when utilizing the recommended ESC’s BEC, or the use of a separate BEC (like the UBEC) or receiver battery pack when using other servos.
Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly more volatile than alkaline or Ni-Cd/Ni-MH batteries used in RC applications. All manufacturer’s instructions and warnings must be followed closely. Mishandling of Li-Po batteries can result in fire. Always follow the manufacturer’s instructions when disposing of Lithium Polymer batteries.
Warning
An RC aircraft is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only in open areas, preferably at AMA (Academy of Model Aeronautics) approved flying sites, following all instructions included with your radio.
Keep loose items that can get entangled in the propeller away from the prop, including loose clothing, or other objects such as pencils and screwdrivers. Especially keep your hands away from the propeller.

4. Slide the stabilizer and tube in position in the fuselage.
Note the direction of the control horn and that it faces the bottom of the fuselage. Slide the remaining stabilizer onto the tube. With both stabilizer halves tight against the fuselage, use a drill and 5/64-inch (2mm) drill bit to drill through the hole in the stabilizer and into the stabilizer tube.

Motor Installation
Required Parts
Fuselage Motor w/mount and accessories #4 washer (4) Cowling Dummy radial engine Radiator scoop (red) Propeller 4-40 x 1/2-inch socket head screw (4) 4-40 x 1/4-inch socket head screw (4)
Required Tools and Adhesives
Rotary tool w/sanding drum Ball driver: 3/32-inch Hobby knife 6-minute epoxy Card stock Low-tack tape Felt-tipped pen Pin drill Drill bit: 1/8-inch (3mm) Threadlock Medium CA Phillips screwdriver: #2
1. Attach the X-Mount to the motor using the screws
provided with the motor and a #2 Phillips screwdriver. Make sure to use threadlock on all four screws so they do not vibrate loose.
2. Attach the motor to the firewall using four
4-40 x 1/2-inch socket head screws, four #4 washers and a 3/32-inch ball driver. Make sure to use threadlock on the four screws to prevent them from vibrating loose.
Note: The blind nuts in the fuselage for mounting the motor can be positioned for a variety of motors. Position them so they are aligned with your particular motor before mounting it to the firewall.
Note: You may paint your dummy motor to simulate the engine found in most full size AT-6's. It is better and easier to paint it at this time before it is installed in the cowling. Please refer to our Scale Accessories section beginning on Page 43 for the correct color choices for the motor.
3. Use a hobby knife and rotary tool to remove the area
in the center of the dummy radial engine.
5. Use 6-minute epoxy to glue the dummy radial engine
inside the cowling.
4. Use a hobby knife to remove the area between each
of the cylinders to allow cooling air to pass through the cowling and over the motor.
6. Cut four strips of card stock. Make a 1/8-inch (3mm)
hole in the end of each strip. Align the hole with the blind nut and use low-tack tape to hold the card stock to the fuselage.
13E-flite AT-6 Texan ARF Assembly Manual
7. Slide the cowling onto the fuselage. The card stock will
be on the outside of the cowling.
Important Information About Your Propeller
It is also very important to check to be sure the propeller is balanced before installing onto the shaft. An unbalanced propeller may strip the gears or cause poor flight characteristics.
8. Slide the propeller and adapter onto the motor shaft.
Position the cowling so it will not be rubbing on the propeller when the motor is running. Tape the cowling in position on the fuselage.
9. Use a felt-tipped pen to transfer the locations for the
4-40 socket head screws onto the outside of the cowling.
Note: If it is necessary to enlarge the hole in the propeller, make sure to check the balance of the propeller afterwards.
10. Use a pin drill and 1/8-inch (3mm) drill bit to drill
the four holes in the cowling for the mounting screws.
11 Slide the cowling back onto the fuselage and secure
it using four 4-40 x 1/4-inch socket head screws and a 3/32-inch ball driver. Make sure to use threadlock on the screws to prevent them from vibrating loose.
12. Use medium CA to glue the radiator scoop to the
side of the fuselage behind the cowling. A felt-tipped pen can be used to color in the scoop to give that open look.

Main Radio Installation
Required Parts
Fuselage Receiver Servo w/hardware (3) Pushrod connector (3) Hook and loop material
Required Tools and Adhesives
Thin CA Felt-tipped pen Side cutters Pliers Pin drill Phillips screwdriver: #1 Drill bit: 1/16-inch (1.5mm), 5/64-inch (2mm)
Note: The installation of the elevator servos will require either of the following options, as using a standard Y-harness for the servos will result in the servos moving the control surfaces in the opposite directions.
Option 1: Use a computer radio to mix the elevator servos together using two separate channels. Ensure you use a correct mix in your radio that has an active trim to trim both elevators in flight.
Option 2: Use a reversing Y-harness (EXRA320) between the two servos and the receiver.
2. Prepare the rudder and elevator servos for installation
by removing any unnecessary arms from the servo horns as shown using side cutters. Install any grommets and brass eyelets at this time as well.
 3. Position the elevator servo in the fuselage, aligning the
outer hole in the servo arm with the elevator pushrod. Mark the locations for the servo mounting screws on the servo mounting rails using a felt-tipped pen.
1. Turn on your radio system and select a new model if
using a computer radio. Make sure all the sub trims have been set to 0 and no mixing functions are turned on. Center the trim levers and stick at this time as well. Plug the servos into the radio system and make sure all servos operate and are centered as well.
