E-flite’s Pulse™ XT 25e is a 25-size electric version of the classic Hangar 9 Pulse 40 XT. This is a great flying sport ARF that’s perfect for intermediate pilots and sport fliers who want to fly an airplane that’s more aerobatic than high-wing airplanes. Based on the original Mike McConville design, the Pulse XT 25e offers excellent features such as its lightweight laser-cut balsa construction and bolt-together wing and tail assembly.

The Pulse XT 25e is easy to maintain and quick to assemble. The wing bolts in place, making it easy to transport. The aluminum landing gear comes already painted along with factory-painted fiberglass cowling and wheel pants. All control surfaces are pre-hinged, control horns are installed, and wheels and axles are mounted on the landing gear.

Depending on your performance desires, you can select from an E-flite Power 25 or Power 32 motor. The Pulse can also be flown from the water by adding the optional E-flite fiberglass .25 size floats (EFLA500) and utilizing the included aft float mount.

Using This Manual

This manual is divided into sections to make assembly of the model 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 (Ο) are performed once, while steps with two circles (Ο Ο) indicate that the step will require repeating, such as for a right or left wing panel, two servos, etc.

We recommend reading through the entire manual before beginning assembly in order to familiarize yourself with the model and its assembly.

Preparation

Your Pulse XT 25e arrives prefinished and it is recommended that you take time to properly prepare your work area. Clean off your work surface and lay down a foam pad or blanket to protect the finish of your model.

This is also a good time to check through the list of required parts and tools and obtain any items not on hand that you may need to complete the model.

Landing Gear Assembly and Installation

Required parts:

Fuselage Main landing gear (wheels installed) Wheel pants (2) 6-32 x 1/2" socket head bolts (2) #6 steel washers (4) #2 x 3/8” sheet metal screws

Required tools and adhesives:

7/64” balldriver Thin CA Dremel rotary tool w/ cutoff wheel #0 Philips screwdriver 1/16 in (1.5mm) drill bit Threadlock Pin drill Felt-tip pen

Ο Ο 1. The axles as supplied are suitable for the optional float kit installation (EFLA500) and require trimming for use with wheel pants. Cut off the exposed portion of the axle leaving approximately 1/4” protruding from the wheel collar. Approximately 1” total axle length is the longest that will fit within the wheel pant. A cutoff wheel in a rotary tool works well for this. Do this for both main axles.

Ο 2. Use a 7/64” balldriver to install the landing gear on the fuselage with two 6-32” x 1/2” socket head bolts and #6 steel washers. The landing gear has a slight sweep and it should be installed on the model angled forward. Threadlock may be used to prevent the bolts from loosening in flight.

Ο Ο 3. Locate the wheel pant on the landing gear and mark the hole locations with a felt-tip pen. The trim lines on the wheel pant and fuselage can be used to align the parts to each other. For another method see the E-tip on page 6.

Ο Ο 4. Using a 1/16 in (1.5mm) drill bit in a pin drill, drill two holes where marked on the wheel pant. Apply a drop of thin CA in each hole to strengthen the wood.

Ο Ο 5. Using a #0 Philips screwdriver, install the wheel pant on the landing gear with two #2 x 1/2” sheet metal screws.

An accurate method of aligning the wheel pants to the fuselage is to level the fuselage with a block under the rear end, then support the wheel pant with another block while marking the location holes for the attachment screws with a felt-tip marker.

Dimensions of 6-7/8” (175mm) under the rearmost point of the fuselage, and 1-1/2” (38mm) to the upper aft corner of the wheel pant work well.

Ο 6. Now install the opposite wheel pant following steps 3 - 5.

Tail Installation

Required Parts

Fuselage Vertical stabilizer Horizontal stabilizer (2) 4-40 x 1/4" locknuts (2) #4 steel washers

Required Tools

1/4” nut driver or wrench

Ο 1. Place the horizontal stabilizer on the aft fuselage. Its leading edge needs to locate under the tab on the rear turtledeck former as shown.

Ο 2. Slide the vertical stabilizer into place. It will be necessary to deflect the rudder to the right in order for the rudder horn to clear the elevator. The 4-40 rods will pass through the horizontal stabilizer and the fuselage. The forward end of the vertical stabilizer assembly will slide over the turtledeck tab, and the fin post will slide between the aft fuselage sides.

Ο 3. Install the two washers and retaining nuts with a 1/4” nut driver or wrench. Tighten them enough that the tail assembly is seated fully and is not loose.

Fuselage Servo Installation

Required Items

(2) Servos and hardware (2) 23 5/8” rudder and elevator pushrods (2) nylon clevises and silicone keepers (2) pushrod keepers Fuselage Radio system (Tx, Rx, battery) JR MatchMaker (optional)

Required Tools

1/16 in (1.5mm) drill bit #1 Philips screwdriver Pin drill Low-tack tape 5/64 in (2mm) drill bit Tongue depressors/popsicle sticks #0 Philips screwdriver Clothespins Thin CA Felt-tip pen Sidecutters

Ο Ο 1. Prepare the fuselage servos by installing the rubber grommets and brass bushings in the mounting lugs. Place the servos in the fuselage and mark the screw hole locations using a felt-tip pen.

Ο Ο 2. Using a 1/16 in (1.5mm) drill bit in a pin drill, drill the four mounting holes for the rudder and elevator servos. Apply a small drop of thin CA to each hole after drilling to strengthen the wood.

Ο Ο 3. Using a #0 Philips screwdriver, and the screws provided with the servos, install the rudder and elevator servos in the fuselage mounting tray as shown. In this view, the front of the fuselage is to the left.

Ο Ο 4. Remove the servo arm using a #1 philips screwdriver. Using sidecutters, trim three of the arms from a standard four arm servo horn, leaving one long arm. Drill a 5/64 in (2mm) hole in the outermost hole using a pin drill. Center the servo using a JR MatchMaker or your radio system, and install the arm as shown using a #1 Philips screwdriver.

Ο Ο 5. Install the clevises and silicone keepers on the pushrods as shown, then install the pushrods in the fuselage from their openings in the rear fuselage sides.

JR’s MatchMaker is a great tool for setting up a model because it allows you to center and cycle servos without the need for a transmitter and receiver.

It will accurately center two servos simultaneously, and also cycle them at various speeds, allowing you to evaluate end points and control surface travels right on the workbench.

Ο Ο 6. Attach the clevises to the control horn on the elevator at the third hole from the mounting surface, and on the rudder at the second hole from the mounting surface. Do not install the silicone keepers at this time. We will do that later in construction on Page 27.

Ο Ο 7. With the control surfaces and servos in their neutral positions, mark the location of the pushrod at the servo arm hole using a felt-tip pen. Place a 90degree bend (towards the bottom of the fuselage) in each of the pushrods in this location. Install the nylon keepers on the pushrods at the servo arms. Trim the remaining wire using sidecutters.

Here are a couple of methods that work well to center the control surfaces for setup.

One technique is to use a pair of tongue depressors and clothespins. Another is to use low-tack tape. Fold a tab in the end of the tape for easy removal

Ο 8. Repeat steps 1 - 7 to install the second servo and pushrod. Note that step 6 dictates which hole to hook the clevis to for both the rudder and elevator.

Receiver Installation

Required Parts

Fuselage Spektrum AR6200 Receiver Adhesive backed hook and loop tape

Ο 1. Install the main and satellite receiver in the fuselage as shownwith adhesive backed hook and loop tape. An alternate location for the satellite receiver is also shown. The rudder and elevator servos can be plugged in at this time.

Motor and Battery Installation

E-flite Power 25

Required Parts

E-flite Power 25 Motor with hardware E-flite 40A ESC E-flite Battery Propeller (4) 4-40 x 1/2" socket head bolts Adhesive backed hook and loop tape (2) Hook and loop straps

Required Tools

3/32” balldriver #1 Philips screwdriver Threadlock

NNoottee::

Your E-flite Pulse XT 25e has been designed to accept the Power 25 and Power 32 motors. We have flown the model on wheels and floats with both motors. The Power 25 delivers adequate power to fly the model on floats but for extreme power you may opt for the Power 32 and 4S battery combination.

Ο 1. Using a #1 Philips screwdriver, install the mount on the rear of the motor using the countersunk Philips head screws included with the motor. You may use threadlock to prevent these screws vibrating loose during flight.
