We recommend installing the lighting kit andinterior in the sequence of steps shown in themanual. Adding these items after the model is builtmay not be possible without causing damage toyour airframe. Please decide prior to beginningconstruction whether or not you would like toincorporate these items in your airplane.Required Tools and AdhesivesTools & EquipmentBox wrench: 10mm Felt-tipped penLow-tack tape Flat blade screwdriverIsopropyl alcohol Hobby knife with #11 bladePaper towel Nut driver: 1/4-inchPetroleum jelly Phillips screwdriver: #1, #2Pin visePliersRulerScissorsSide cutters SquareToothpickT-pinsMixing sticks Mixing cupsDental floss SandpaperDrill bit: 1/16-inch (1.5mm), 5/64-inch (2mm),7/64-inch (3mm)Hex wrench: 1.5mm, 2mm, 3/32-inch, 5/64-inch,1/8-inchOptional Tools & EquipmentBalancing stand (optional)Adhesives30-minute epoxy PAAPT39Medium CA PAAPT02Thin CA PAAPT08Threadlock PAAPT42Formula 560 Canopy Glue PAAPT56Before Starting AssemblyBefore beginning the assembly of your model, removeeach part from its bag for inspection. Closely inspectthe fuselage, wing panels, rudder and stabilizer fordamage. If you find any damaged or missing parts,contact the place of purchase.If you find any wrinkles in the covering, use a heat gun(HAN100) and covering glove (HAN150) or coveringiron (HAN101) with a sealing iron sock (HAN141) toremove them. Use caution while working around seamsor areas where the colors overlap to prevent pullingthe seams.During the course of building your model, wesuggest you use a soft base for the building surface.Such things as a foam stand, large piece ofbedding foam or a thick bath towel will work welland help protect the model from damage duringassembly. This is not shown in the instructionsto provide the greatest detail in the photos.When referencing directions (up, down, left,right, top and bottom), take note that these arein relationship to the pilot sitting in the cockpitof the aircraft unless noted otherwise.Hinging the Ailerons and FlapsRequired PartsWing panel (right and left)Aileron (right and left)Flap (right and left) Flap hinge (6)CA hinge (8)Required Tools and AdhesivesSide cutters Petroleum jellyT-pinsToothpicksThin CALow-tack tapePin viseDrill bit: 1/16-inch (1.5mm)30-minute epoxy Isopropyl alcoholMixing sticks Epoxy cupsPaper towel 1. Locate the wing panel. Separate the aileron andflap from the wing panel by removing the tapeholding them to the wing panel.E-flite Super Cub 25e ARF Assembly Manual5

2. Locate three hinges for the flaps. Use side cuttersto trim one end of each hinge to 11/16-inch(17mm). The trimmed end will be placed in the flap. 4. Fit the hinge and flap to the wing. Position theflap so it aligns with the wing and that the hingeline is equal along the entire length of the flap. 6. Remove each hinge and apply a small amountof petroleum jelly to the hinge point in order to helpprevent the glue from penetrating the hinge whichcould prevent it from operating correctly. 3. Insert the trimmed end of the hinges into the flap.Check that the hinge moves perpendicular to thehinge line. Also check to ensure that the hinge is notprotruding through the top of the flap skin. If yousee a bump, trim a little more off of the hinge. 5. Check that the flap can move freely through itsrange of motion. This will ensure that the hinges areinstalled correctly.Dipping the hinge knuckles in heated petroleumjelly (in a liquid state) is easier than trying toapply it with a toothpick in the gel state. 7. Remove the flap and hinges. Mix a small amountof 30-minute epoxy. Use a toothpick to apply theepoxy inside the holes in the wing and flap, theninstall the hinges. Check to make sure the flap ispositioned as described in steps 4 and 5.6 E-flite Super Cub 25e ARF Assembly Manual

8. Use a small amount of low-tack tape to hold theflap in position until the epoxy fully cures. Use apaper towel and isopropyl alcohol to remove anyexcess epoxy before it cures. 11. Place a T-pin in the center of each of the fourhinges. This will center the hinges equally in theaileron and wing when they are installed. 13. Slide the aileron into position, guiding thehinges into the hinge slots in the wing.9. Repeat steps 1 through 8 to install theremaining flap. 12. Insert the hinges in the ailerons. The T-pin will reston the edge of the aileron bevel. 14. Remove the T-pins from the hinges. Position theaileron so the hinge gap is as small as possible.Also check that the aileron is centered between theflap and wing tip. 10. Use a pin vise and 1/16-inch (1.5mm) drillbit to drill a hole in the center of each hinge slot inthe aileron and wing to create a tunnel for the CAto wick into. This will allow the CA to penetrate thehinge, creating a better bond between the hinge andsurrounding wood.E-flite Super Cub 25e ARF Assembly Manual7

15. Saturate each hinge with thin CA. Apply CA toboth the top and bottom of the hinge. 16. Once the CA has cured, gently pull on thecontrol surface and wing to make sure the hinges areglued securely. If not, apply CA to those hinges thatare not glued and recheck. 17. Move the control surface through its range ofmotion several times to break in the hinges. Thiswill reduce the initial load on the servo duringyour first flights.18. Repeat steps 10 through 17 to install theremaining aileron. Once the glue has fully cured onthe flaps, remove the tape placed in step 8.Aileron and Flap Servo InstallationRequired PartsWing panel (right and left)Transmitter ReceiverNylon clevis (4) Nylon control horn (4)Receiver battery Silicone tubing (4)Servo with hardware (4)2mm x 8mm washer head self-tapping screw (16)2mm x 8mm self-tapping screw (8)Aileron pushrod, 2 9 / 16 -inch (65mm) (2)Flap pushrod, 2 5 / 16 -inch (59mm) (2)Servo extension, 6-inch (152mm) (2)Required Tools and AdhesivesThin CA Phillips screwdriver: #1Pin viseDrill bit: 5/64-inch (2mm)Dental floss Hobby knife with #11 bladeCanopy glue Low-tack tape 1.

Use sandpaper tolightly sand each of the carbon rods. Mix a smallamount of 30-minute epoxy. Use a toothpick toapply the epoxy in the holes for the carbon rods inboth stabilizer halves and the fuselage. Place thestabilizers and carbon rods back into position andallow the epoxy to fully cure before attaching thebracing. Remove any excess epoxy before it curesusing a paper towel and isopropyl alcohol.18 E-flite Super Cub 25e ARF Assembly Manual

5. Use a pin vise and 7/64-inch (3mm) drill bit toenlarge the hole in the eight nylon brace ends.7. Attach the nylon ends to the stabilizer usingtwo 4-40 x 5/8-inch socket head cap screws andtwo 4-40 lock nuts. Use a 3/32-inch hex wrenchand 1/4-inch nut driver to tighten the hardware.Leave the hardware slightly loose so the rods canbe positioned.When installing the rods, make sure they are intension with one another slightly. This is what givesthe tail bracing its strength. Nothing should bewarped, and the anchor points are the two attachpoints in the bottom of the fuselage. The fin shouldnot bend to one side and the stab should remainflat. This may take some adjustment to get right. 6. Thread the nylon ends on the two 2-56 x 6 1 / 2 -inch threaded rods and the two 2-56 x 6 3 / 4 -inchthreaded rod.8. Adjust the position of the nylon ends so the holesalign with the holes in the fuselage. Use a squareto make sure the stabilizer isn’t being overly-forcedinto position. Use a 4-40 x 1/4-inch socket headscrew and a 3/32-inch hex wrench to install thescrews, securing the ends to the fuselage.Important: The shorter 2-56 x 6 1 / 2 -inch threadedrods are located on the bottom of the stabilizer,and the shorter 2-56 x 6 3 / 4 -inch threaded rodsare located on the top of the stabilizer.Always use threadlock on metal-to-metal fastenersto prevent them from vibrating loose.E-flite Super Cub 25e ARF Assembly Manual19

Control Throws1. Turn on the transmitter and receiver of yourmodel. Check the movement of the rudder usingthe transmitter. When the stick is moved right, therudder should also move right. Reverse the directionof the servo at the transmitter if necessary.2. Check the movement of the elevator with theradio system. Moving the elevator stick toward thebottom of the transmitter should make the airplaneelevator move up.3. Check the movement of the ailerons with theradio system. Moving the aileron stick right shouldmake the right aileron move up and the leftaileron move down.4. Use a ruler to adjust the throw of the elevator,ailerons and rudder. Adjust the position ofthe pushrod at the control horn to achieve thefollowing measurements when moving the sticks totheir endpoints.The Super Cub benefits greatly from having ailerondifferential. The suggested DX8 transmitter has aprovision for this that will allow you to set this upwithout adjusting your ailerons travel volumes. Thedifferential on the DX8 should be set at 80%. Thissetting should allow the travel measurements to matchthese below. If not using a DX8, you can also set thetravel adjustment to match the suggested throws.AileronHigh RateUp: 1-inch 25mmDown: 1/4-inch 6mmLow RateUp: 11/16-inch 18mmDown: 5/32-inch 4mmElevatorHigh RateUp: 1 1 / 8 -inch 28mm 15% ExpoDown: 1 1 / 8 -inch 28mm 15% ExpoLow RateUp: 3/4-inch 19mmDown: 3/4-inch 19mmRudderHigh RateRight: 1 1 / 2 -inch 38mmLeft: 1 1 / 2 -inch 38mmLow RateRight: 1-inch 25mmLeft: 1-inch 25mmFlapMid 3/4-inch 19mmFull 1 1 / 4 -inch 32mmElevator-to-Flap mixingMid flap: 5/32-inch (4mm) down elevatorFull flap: 9/32-inch (7mm) down elevatorMeasurements are taken at the inner orwidest point on the control surface.These are general guidelines measured from our ownflight tests. You can experiment with higher rates tomatch your preferred style of flying.Travel Adjust and Sub-Trims are not listedand should be adjusted according to eachindividual model and preference.We highly recommend re-binding the radiosystem once all the control throws are set. This willkeep the servos from moving to their endpointsuntil the transmitter and receiver connect.Check Your RadioPreflightBefore going to the field, be sure your batteries arefully charged per the instructions included with yourradio. Charge the transmitter and motor batteryfor your airplane. Use the recommended chargersupplied with your particular radio system, followingthe instructions provided with the radio. In mostcases, the radio should be charged the night beforegoing out flying.Before each flying session, be sure to range check yourradio. See your radio manual for the recommendedrange and instructions for your radio system. Eachradio manufacturer specifies different procedures fortheir radio systems. Next, run the motor. With themodel securely anchored, check the range again.The range test should not be significantly affected. Ifit is, don’t attempt to fly! Have your radio equipmentchecked out by the manufacturer.Double-check that all controls (aileron, elevator, rudderand throttle) move in the correct direction.Check the radio installation and make sure all thecontrol surfaces are moving correctly (i.e., the correctdirection and with the recommended throws).Check all the control horns, servo horns, and clevisesto make sure they are secure and in good condition.40 E-flite Super Cub 25e ARF Assembly Manual

Range Test Your RadioBefore each flying session, and especially with a newmodel, it is important to perform a range check. Itis helpful to have another person available to assistduring the range check. If you are using a Spektrumtransmitter, please refer to your transmitter’s manual fordetailed instructions on the range check process. 1. With the model resting on the ground, stand 30paces (approximately 90 feet) away from the model.2. Face the model with the transmitter in yournormal flying position. Be sure the throttle is in thefull down position and plug the flight battery intothe speed control.3. As you move the controls, watch to be sure theairplane’s motor and controls operate smoothly.You should have total control of the model at 30paces (90 feet).Flying Your ModelOkay, it’s time for the moment of truth. Now that youhave your Super Cub at the field and put together, takethe opportunity to check over everything one more timeto ensure that all is in order. Verify control direction,battery level, CG and range check your model. Aftereverything checks out, the only thing left to do isviolate some air molecules.Set your throttle trim to a low idle; this will be yourflight idle. Taxi out to the runway and line up with thecenterline. Smoothly advance the throttle and maintaindirectional control with the rudder. The Super Cub isa very light airplane and has a very large wing, so itdoesn’t take much airspeed to get airborne. If you holda little up elevator, the airplane will be off in about 15feet. If you apply a little down pressure to raise thetail, you’ll have a longer takeoff run. Once you areairborne, establish a gentle climb angle and make aclimbing turn to parallel yourself with the runway.Set up on a downwind leg and reduce power. Whenyou are abeam your touchdown point, add the firstnotch of flaps. Continue your descent into your baseleg and onto final. Gauge your decent rate and let thatbe your judge whether or not to fully extend your flaps.When you are over the threshold, begin to reducepower to idle. When you get close to the ground,round out your descent and flare. You should touchdown gently. Once back on the ground, maintaindirectional control with the rudder.That’s it! You’ve just flown your Platinum Series SuperCub from E-flite. We wish you many more successfuland enjoyable flights with it in the future!4. If control issues exist, call the appropriateHorizon Product Support office (see addresses listedin the Warranty Services section of this manual) orgo to horizonhobby.com to find a local Spektrumdistributor in your country for service if using aSpektrum radio system.Once at altitude, you’ll find yourself cruising aroundat half throttle. Trim the airplane out and get the feelfor how it flies. Cubs are inherently very gentle, soyou’ll have no issues with maintaining control orgetting behind the airplane. After you have the feelfor it, try your hand at a few basic maneuvers—loops,rolls, wingovers, spins, etc. The airplane will performthese with great ease. Many full scale Cubs fly thesebarnstorming-type maneuvers, so coupled with thedetail of this Platinum Series design, you’ll have a hardtime distinguishing your airplane from the real one!Unfortunately, all good things must come to an endand your flight battery is the malevolent dictator of thisdirective. Before you try and set up for a landing, pullthe power back and try some slow flight. Extend theflaps and get used to how the airplane handles withflaps extended. They have quite a bit of area, so theywill induce a lot of drag when you have them fullyextended. It’s best in a landing configuration to not tryand drag the airplane in with flaps; you need to aim itat the ground and fly it in.E-flite Super Cub 25e ARF Assembly Manual41

Daily Flight Checks1. Check the battery voltage of the transmitterbattery. Do not fly below the manufacturer’srecommended voltage. To do so may cause youraircraft to crash.When you check these batteries, ensure you have thepolarities correct on your expanded scale voltmeter.2. Check all hardware (linkages, screws, nuts, andbolts) prior to each day’s flight. Be sure that bindingdoes not occur and that all parts are properlysecured.3. Ensure all surfaces are moving in theproper manner.4. Perform a ground range check before each day’sflying session.5. Prior to starting your aircraft, turn off yourtransmitter, then turn it back on. Do this each timeyou start your aircraft. If any critical switches are onwithout your knowledge, the transmitter alarm willsound a warning.6.
