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

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.

Ο 2. Using a 3/32” balldriver, install the motor on the firewall with four 4-40 x 1/2" socket head bolts. The motor wires should exit towards the bottom of the fuselage. You may use threadlock to prevent these screws from vibrating loose in flight.

Ο 3. Remove the battery hatch by sliding it forward to disengage the magnets, and lifting at the rear. It can then be pulled rearwards and off the model.

Ο 4. Install the battery with two hook and loop straps. Slots are provided on the floor of the battery compartment for the straps to pass through. The natural curl of the straps will allow them to be fed down one slot, under the battery compartment floor, then up through the opposite slot.

Ο 5. Install the ESC on the right-hand side of the battery compartment with hook and loop tape. The battery leads, switch leads and throttle leads will be towards the rear of the model. Connect the ESC to the motor.

Motor and Battery Installation

E-flite Power 32

Required Parts

E-flite Power 32 Motor with hardware E-flite 60A ESC E-flite Battery Propeller (4) 4-40 x 3/4" socket head bolts Adhesive backed hook and loop tape (2) Hook and loop straps (4) 4mm aluminum motor mount spacers

Required Tools

3/32” balldriver #1 Philips screwdriver Threadlock

Ο 2.. Using a 3/32” balldriver, install the motor on the firewall with four 4-40 x 3/4" socket head bolts and four 4mm aluminum spacers. The motor wires should exit towards the bottom of the fuselage. You may use threadlock to prevent these screws from vibrating loose in flight.

Ο 3. Remove the battery hatch by sliding it forward to disengage the magnets, and lifting at the rear. It can then be pulled rearwards and off the model.

Should you find that the rotation direction of your E-flite Power Brushless Outrunner is opposite to that needed, reversing it is just a matter of switching any two of the motor wires.

E-flite’s Power series brushless motors and Pro series controllers are outfitted with red, blue and black power wires. Matching the color is not critical to their operation, it only affects the direction of rotation.

Cowling, Propeller and Spinner Installation

Required Parts

Fuselage Cowling (4) 4-40 x 1/4" socket head bolts (4) #4 steel washers Spinner with screws Propeller Propeller adapter (supplied with motor)

Required Tools

3/32” balldriver #1 Philips screwdriver Tapered reamer Dremel rotary tool with high speed cutter

Ο 1. Using a 3/32” balldriver, install the cowling with four 4-40 x 1/4" socket head bolts and four #4 steel washers.

Ο 2. The spinner backplate requires the hole to be enlarged to suit the propeller adapter. For a snug fit on the prop adapter the hole should be approximately 9.5mm diameter. This is best done with a tapered reamer. Proceed carefully and check the fit on the shaft as you enlarge the hole.

Ο 3. Install the propeller adapter, spinner backplate and propeller. Tighten the propeller nut with a suitably sized screwdriver or Allen wrench shaft.

Ο 4. Install the spinner cone using a #1 Philips screwdriver and the supplied Philips head screws.

An alternate method to drilling completely through the spinner backplate is to grind only the relief necessary to clear the propeller adapter hub.This can be done by hand using a straight cutter in a Dremel rotary tool. The remainder of the hole can be left at its orginal size and will be a good fit on the propeller shaft.

Wing Joining

Required Parts

Wing halves (L and R) (2) dihedral joiners (2) leading edge dowels (2) 6-32 x 1” socket head bolts (2) #6 steel washers

Required Tools and Adhesives

Ο Ο 1. Install the leading edge dowels in the wing panels with 12-minute epoxy. Use paper towels and rubbing alcohol to clean any epoxy that squeezes out onto the wing.

Ο Ο 2.. Upon installation, approximately 5/16” to 3/8” of the dowel should protrude from the leading edge of the wing.

Ο Ο 3. The rear side of the dowel is accessible through the wing root rib and a small amount of epoxy can be added here to secure its installation.

Ο 4. Apply low-tack tape to the upper and lower surfaces of the center of the wing panels as shown. This will allow for easy clean up of any excess glue and make for a clean joint.

Ο 6. 12-minute epoxy is used to install the dihedral joiners and join the wing. Glue the two dihedral joiners to each other.

Ο 5. Apply a piece of clear tape to the front and rear wing saddle area where the wing leading and trailing edges will come in contact with the fuselage.

Ο 7. Using a mixing stick, apply epoxy to the dihedral joiner slot in each wing panel, and to the exposed root rib of one wing panel.

Ο 8. Install the dihedral joiners in one wing slot and slide the other wing panel onto the joiner. Wipe off any excess epoxy that squeezes out of the joint with rubbing alcohol and a paper towel.

Using a 7/64” balldriver, install the wing on the fuselage with two 6-32” x 1” socket head bolts. Tighten the bolts just enough that the wing sits snugly in the wing saddle, and that the two wing panels are exactly aligned with each other along their bottom surface. Wipe off any excess glue from the wing joint with a paper towel.

Aileron Servo Installation.

Required Parts

(2) servos and hardware (2) 6” servo extension leads (2) 4-3/4" aileron pushrods (2) nylon clevises and silicone keepers (2) pushrod keepers Radio system (Tx, Rx, battery) JR MatchMaker (optional)

Ο 1. Install the rubber grommets and brass bushings in each aileron servo. Attach a 6” servo extension lead to each servo and secure it with tape, heat shrink tubing or dental floss.

9. Allow the glue to dry then remove the wing from the fuselage. Remove the tape from the wing and fuselage.

Ο 2. A string is provided in each wing half to draw the aileron lead through the wing. Attach the end of the string to the aileron servo lead and pull it carefully through the wing to the center. Once both leads have been pulled through, they can be secured to each other with tape to prevent them falling back into the wing.

Ο Ο 3. Place the servos in the wing openings and mark the screw hole locations with a felt-tip pen.

Ο Ο 4. Using a 1/16 in (1.5mm) drill bit in a pin drill, drill the four mounting holes for each aileron servo. After drilling, apply a small drop of thin CA to each hole to strengthen the wood.

Ο Ο 5. Using a #0 Philips screwdriver, and the screws provided with the servos, install the aileron servos with the output shaft towards the trailing edge of the wing.

Ο Ο 6. Using a #1 Philips screwdriver remove the servo horn. Using sidecutters remove three of the four arms, leaving one long arm. Using a pin drill, enlarge the outermost hole to 5/64 in (2mm) to accept the pushrod. Center the servo and install the arm towards the wing tip as shown.

Ο Ο 8. Center the aileron servo using your radio or JR MatchMaker. Attach the clevis to the aileron horn at the third hole from the surface and mark the length at the servo arm. Bend the pushrod up (away from the wing surface) at this location and install it on the servo arm with a pushrod keeper.

Ο Ο 7. Prepare each of the 4-3/4” long aileron pushrods with a clevis and silicone keeper.

9. Follow steps 3 through 8 to install the opposite aileron servo.

If you opt to fly from land please proceed to the Flight Preparation section on page 27. If you are installing floats, please proceed to the next page.

Optional Float Installation.

Required parts:

E-flite fiberglass 25-size Float Set Sullivan 36” flex cable Pulse XT 25e (assembled) (4) 1/8” float mount spacers (included in Pulse kit)

Required tools and adhesives:

#1 Philips screwdriver Sidecutters 7/64 in balldriver 5/64 in (2mm) drill bit

1.5mm Allen wrench 11/64 in (4.5mm) drill bit 1/16 in (1.5mm) drill bit Thin CA Pin drill Flat file Felt-tip pen Drill Threadlock Ruler

Ο 1. Locate the parts from the float set as shown below, plus the four float mount spacers from your Pulse kit. Not required for float installation on the Pulse are the wire float mount, the sub-fin and the water rudder pushrod.

Refer to the Float Set assembly manual in addition to these instructions for reference when assembling the floats.

Ο Ο 2. Using a #1 Philips screwdriver, attach two of the mounting brackets and spacers to each of the floats with 3mm x 12mm sheet metal screws. For the two floats a total of four brackets, four spacers and sixteen screws are required.

Ο Ο 3. Remove the wheel pants and wheels from the main landing gear on your Pulse. The 1.5mm Allen wrench in the Float Set hardware bag will fit the Pulse wheel collars. Install the aft float mount landing gear using the wing attach bolts. When correctly installed the gear will angle forward and the hole for the water rudder cable will be on the left.

Ο Ο 4. Use a file or rotary tool to make a 1/4” wide flat on the top of each of the four axles. The flat should be located approximately 9/16” (14mm) outboard of the hexagonal axle base.

Ο Ο 5. Attach the floats using four 5/32” wheel collars and four 3mm setscrews using the 1.5mm Allen wrench provided in the float kit. Make sure to use threadlock when installing the setscrews in the flats made previously.

Note: One of the floats has holes drilled in the aft end for the water rudder bracket. This float will get mounted on the left side of your Pulse XT 25e.

Ο 6. Attach a nylon bracket to the aft end of the left float with four 3mm x 12mm sheet metal screws. Using a drill and 11/64 in (4.5mm) drill bit, enlarge the hole through the mounting bracket.

Ο 7. Install the rudder assembly, steering arm and pushrod connector on the nylon bracket. Refer to pages 12 and 13 in the Float Set assembly manual for guidance. The pushrod connector will go in the hole closest to the rudder post.

Ο 8. Install a pushrod connector on the outermost hole in the rudder horn as shown. Refer to page 13 of the Float Set assembly manual for guidance.

Ο 9. The Sullivan flex cable and tube need to be cut to length prior to installation. The cable length will be approximately 31.5 in and the tube length approximately 26.5 in. With the pushrod cable inside the pushrod tube, attach the tube to the float with a full brass strap and two 2mm x 10mm sheet metal screws.The end of the pushrod tube will be approximately 1.5” behind the brass strap. The cable can now be installed in the pushrod connector with a 3mm setscrew as shown.

Ο 10. Install the other end of the cable in the pushrod connector on the rudder horn as shown and secure with a 3mm setscrew using a 1.5mm Allen wrench.

Ο 11. Use the two remaining full brass straps to attach the pushrod tube to the left side of the Pulse fuselage. Locate the straps as shown in the picture below using the following dimensions as a guide. There are fuselage frames at these locations; ensure that the screws are located in the center of the frame and will not interfere with any internal items such as pushrods.

Aft strap: approximately 3/8” forward of stabilizer leading edge, and centered 9/16” up from bottom of fuselage.

Forward strap: approximately 6-1/2” forward of stabilizer leading edge, and 5/8” up from bottom of fuselage.

Use a 1/16” drill bit and pin drill to make the holes for the 2mm x 10mm screws. Strengthen each hole with a small drop of thin CA and allow to cure. Using a #0 Philips screwdriver, attach the straps over the pushrod tube with both the air and water rudders centered.

Ο 12. Attach the water rudder cable housing to the left float mount strut using the cable tie provided in the Float Set hardware bag. Trim the excess tie material using cutters or a blade.

13. Refer to page 16 in the Float Set assembly manual to finalize the installation of the floats. This will involve final adjustment of linkages to ensure that the rudder is aligned and operates correctly.

It is extremely important that you verify the center of gravity is still correct with the floats installed. It will be more accurate to check the CG of your float equipped Pulse with the model right side up, as opposed to inverted when the wheels are installed.

Pages 26 and 27 of your Float Set assembly manual include some tips for flying from floats. If you are a first-time water flier, please take the time to read these pages before heading out to the lake.

Flight Preparation

Control Directions

1. Connect the throttle lead from the ESC to the receiver.

2. Connect the wing servos to the receiver with two 3” extension leads (JSP98100) if using the dual aileron function in your transmitter, otherwise use a Y-harness (JSP98020). Attach the wing to the model.

3. Connect battery power to the ESC and using your radio verify the correct rotation of the motor. Viewed in the direction of flight, the propeller should rotate clockwise. We have printed an E-tip regarding the switching direction of your motor on page 15 for reference.

4. Center the trims on your transmitter and check that the control surfaces are neutral. Large adjustments should be made at the control surface by adjusting the clevis, fine-tuning can be done using the transmitter subtrim function.

5. Verify that the control surfaces operate in the correct direction using the following diagram. Use the servo reversing function in your transmitter as necessary to correct the direction of motion.

Control Throws

Use a ruler to set the control throws for the ailerons, rudder and elevator. The position of the pushrod can be altered at either the servo or control surface to adjust the amount of control throw. Moving the pushrod closer to the center of the servo, or further from the control surface, will have the effect of reducing surface travel, and vice versa.

These measurements are taken at the widest part of the control surface. They are a general guide from our own flight testing and you can experiment with more or less throw to suit your preferred flying style.

Low Rate

Aileron 3/8” (10mm) up and down Elevator 7/8” (22mm) up and down Rudder 2” (50mm) left and right

High Rate

Aileron 5/8” (16mm) up and down Elevator 1-1/8” (29mm) up and down Rudder 2-1/2” (64mm) left and right

Once you have set the control throws, install the silicone keepers on all the clevises. This will prevent any possible failure in flight of a clevis popping loose.

Center of Gravity (CG)

The recommended center of gravity range for the Pulse XT 25e is 2.5 - 3.0” (63 - 76mm) behind the leading edge of the wing. Before making this measurement ensure that the model is in a ready-to-fly state, with all components in place including batteries, hatches and radio equipment.

Place a piece of tape on the upper surface of each wing beside the fuselage and mark the center of gravity location with a felt-tip marker. Suspend the

iinnvveerrtteedd

model or it can be lifted with a finger at each of those points.

NNoottee:

If flying with floats please check the CG with model right side up.

at the measured points on a commercial CG measuring device,

Preflight

Battery Charging

Use the recommended charger for the batteries being used in your radio and model, and follow the charging instructions.

If using Lithium Polymer (LiPo) batteries be aware that they are significantly more volatile than alkaline, Nickel Cadmium or Nickel Metal Hydride batteries used in other RC applications. Follow the battery manufacturer’s instructions and warnings closely. Mishandling or incorrect handling of LiPo batteries can result in fire. Do not charge LiPo batteries unattended.

Refer to page 31 for more detailed information on handling LiPo batteries.

The model should hang level when suspended at the desired point. The battery pack can be moved forward or aft to correct any tendency for the model to balance nose or tail heavy. Stick-on lead weights can also be used for this purpose.

After the model is flown you may wish to adjust the center of gravity slightly to suit your flying style. Use caution if moving the CG further aft as it will decrease the stability of the model, and increase control sensitivity, particularly the elevator. Moving the CG forward will have the opposite effect.

Range Testing your Radio

Be sure to range test your radio before each flying session, or when you have made any repairs or changes to the model. Follow the instructions provided with your radio to perform the range check, which usually involves limiting the output power of the transmitter while checking model function at a prescribed distance.

Final Checks

Before flying, make a last check of the model and it’s functions, especially if you have made any setup or programming changes.

- confirm that all control surfaces move in the correct direction

- check the radio installation for security

- check motor installation and correct direction of rotation

- check the integrity of control surfaces and hinges

- check pushrods and control horns for security of attachment

•LiPo batteries may explode if damaged or disposed of improperly.

•Always inspect batteries before charging.

•Never charge or use a LiPo battery that shows any damage or disfigurement of any kind. Swelling is a sign of internal damage. Any breach of protective cover, wiring or plugs is also a reason to discontinue use (see Disposal Instructions).

•Use a specific Lithium Polymer charger only. Do not use a NiCd or NiMH charger- failure to do so may cause a fire, which may result in personal injury and/or property damage.

•Never charge around or in the area of any flammable or combustible materials.

•Always charge LiPo batteries in or on fire resistant materials or containers.

•Never leave battery and charger unattended while in use. Improper charging or discharging of LiPo batteries could result in fire.

•Constantly monitor the temperature of the battery pack while charging. If the battery becomes hot to the touch discontinue charging immediately. Disconnect the battery from the charger and observe it in a safe place for at least 1 minute.

•If at any time you see a battery starting to balloon or swell, discontinue charging or using immediately.

•Lithium batteries can still ignite after at least 45 minutes due to a delayed chemical reaction. If the battery is damaged or overheats, observe the battery in a safe area outside of any building or vehicle and away from combustible material.

•Do not allow children to charge LiPo battery packs.

•Do not allow children to use LiPo batteries without direct adult supervision.

•Shorting the wire leads can cause fire. If you accidentally short the wires, the battery must be placed in a safe area for observation for at least 15 minutes.

•Never store or charge a battery pack where the temperature will go below 32 degrees Fahrenheit or above 130 degrees Fahrenheit. Extreme temperatures will damage the battery pack and may cause fire. Battery performance may be diminished by less extreme temperatures.

•Any of the following may cause the battery to be damaged resulting in battery swelling, leaking or fire:

- Bending, folding or dropping of the battery

- Damaging the edge seal of the battery

- Taking the battery apart

- Mixing cells of different chemistry, or types, or sizes

- Mixing cells of different ages

Crash Damage

If there are signs of smoke or overheating, DO NOT go near the battery or equipment until it has been observed from a safe distance for at least 15 minutes. Once it is safe, remove the battery and check for damage. Dispose of damaged batteries appropriately.

Swollen Batteries

Immediately stop using or charging a battery showing any signs of swelling or becoming too warm. If the battery is not warm to the touch, move it to an open safe area and observe it for at least 15 minutes. Be VERY CAREFUL when moving the batteries. Do NOT put ANY pressure on the batteries or covering as this may cause fire.

Additional Information and Guidelines

1. Battery temperature is the best indicator for safety. The E-flite LiPo battery’s temperature should never drop below 32 degrees Fahrenheit or go above 130 degrees Fahrenheit while charging or discharging.

2. Changing plugs or connectors is not recommended as the process is dangerous and any error can cause fire due to shorts, reverse polarity or other improper handling which can cause battery damage.

3. Batteries should be stored in a vented, fire resistant container. Each pack should be stored in its own locked plastic bag within the container. The number of packs per container should be extremely limited to avoid chain reactions. Storage temperatures should not fall below 32 degrees Fahrenheit or above 130 degrees Fahrenheit. Damaged batteries must be kept at even more ambient temperatures. High temperatures may cause fire even with undamaged batteries.

Battery Disposal

LiPo batteries require special handling for safe disposal. The following are basic instructions for safe disposal. For more detailed safety, disposal and recycling please go to: www.rbrc.org or www.earth911.org.

Basic Disposal Instructions

Before discarding any LiPo battery it must be rendered safe. The following steps must be taken to avoid damage or injury to yourself, your property and anyone who comes in contact with the battery.

If the battery is undamaged but no longer useful:

1. Discharge the battery to a maximum of 2.5V using a slow, safe discharge method.

2. Leave battery discharged and retest after 24 hours. Many batteries experience ‘rebound’ and may measure more than 2.5V after 24 hours. If the voltage is greater than 2.5, repeat the procedure until the battery measures

2.5V or less.

3. Insulate each wire lead with electrical tape or other suitable material.

4. Assure that wire leads cannot touch each other by taping them to opposite sides of the battery.

5. Place battery in a sealed plastic bag and place bag in a sealed, vented, fire-safe container.

6. Use fire-safe container to deliver battery to a recycling center authorized for Lithium Polymer batteries. Please note that not all battery recycling services include LiPo’s. If no LiPo recycling facility is available in your area, contact your local or state Hazmat agencies for instructions.

7. If the battery or wiring is damaged, please contact your local or state Hazmat facilities for instructions. Batteries must be rendered safe before being transported or recycled. Do NOT transport or ship batteries which have more than a 2.5V charge OR that show signs of damage without following the instructions given by authorities. Damaged batteries should be rendered as safe as possible and stored in a vented fireproof container until recycled.
