Recommended Radio Equipment You will need a minimum of a 4-channel transmitter, receiver and four servos. You can choose to purchase a complete radio system, or if you are using an existing transmitter, just purchase the other required equipment separately. We recommend the crystal-free, interferencefree Spektrum™ DX5e 2.4GHz DSM® 5-channel system. If using your own transmitter, we recommend the JR SPORT MN48 and MC35 servos.
Rudder and Elevator Servo Installation Parts Required Fuselage assembly Radio system Tools Required Pin vise Sidecutters Felt-tipped pen Mini servos with hardware (2) JR MatchMaker Ο 2. Install the grommets and bushings in the rudder and elevator servos. Note that the bushing is installed from the bottom of the mounting lugs. Ο 4. Place the rudder and elevator servos in the fuselage servo cutouts and mark the mounting holes with a felt-tipped pen. Ο 3.
Ο 6. Apply 2-3 drops of thin CA to each mounting screw hole to strengthen the wood. This will make the servo mounting screws more secure when installed. Stabilizer and Fin Installation Parts Required Fuselage Elevator CA hinges (8) Tools Re quired Felt-tipped pen Allen wrench Rubbing alcohol 6-minute epoxy Mixing cups Ο 3.

Ο 11. Align the elevator with the stabilizer and apply 2 - 3 drops of thin CA to each hinge. Do not use accelerator on the hinges as the CA needs to penetrate the hinge for a complete bond. Ο 13. Locate the tailwheel assembly. Using the supplied Allen wrench, separate the tailwheel shaft from the wheel assembly. Ο 12. Using the marks made in steps 1, 2 and 4, check that the stabilizer is aligned with the fuselage. Apply several drops of thin CA to each side of the joint to glue the stabilizer in place.
Ο 16. Apply a few drops of thin CA to each rudder hinge. Do not use accelerator on the hinges so the CA can penetrate the hinges completely.
Ο 4. Use a pair of pliers to place a bend in the rudder pushrod so that the threaded end is 1/2-inch from the fuselage side. Ο 6. Install a silicone keeper and clevis on the rudder pushrod so that the clevis pin is aligned with the rudder hinge line. Ο 8. Use the marks and the control horn as reference to drill the mounting holes with a pin vise and 1/16inch drill bit. Ο 5.

Use a 3/32-inch balldriver to install the four 4-40 x 3/8-inch Allen bolts and #4 washers. Apply a small amount of threadlock to the bolts to prevent them from vibrating loose.
ΟΟ 4. Hold the servo in place on the underside of the hatch with the arm centered in the opening and aligned with the edge of the hatch. ΟΟ 5. Use a pencil to mark the location of the servo mounting tabs. E-flite Stearman PT-17 15e ARF Assembly Manual ΟΟ 6. Use medium CA or 6-minute epoxy to glue the servo mounting blocks to the aileron hatch. ΟΟ 8. Use a 1/16-inch drill bit in a pin vise to make the servo mounting holes. ΟΟ 7.
ΟΟ 10. Using a #0 Philips screwdriver, install the aileron servo to the hatch with the screws provided with the servo. ΟΟ 11. Use a 1/16-inch drill bit in a pin vise to enlarge the outer hole in the servo arm. ΟΟ 12. Remove the tape from the string near the aileron servo opening in the wing. Tape or tie the string to the aileron servo lead. and use it to pull the lead through the wing. ΟΟ 13. Use the string to pull the aileron servo lead through the wing. ΟΟ 14.
Aileron Installation Parts Required Lower wing panels w/ailerons (L & R) CA hinges (6) Tools Required Thin CA ΟΟ 2. Remove the tape holding the aileron to the wing and separate the aileron. Insert a hinge into each of the hinge slots in the leading edge of the aileron. ΟΟ 4. Slide the aileron and wing panel together on the hinges then remove the T-pins. Felt-tipped pen ΟΟ 1. Prepare three CA hinges by inserting a T-pin in the center of each hinge. ΟΟ 3.
ΟΟ 6. Apply a few drops of thin CA to each of the three aileron hinges. Do not use accelerator as the CA needs to penetrate the hinges fully for a complete bond. Aileron Linkage Installation Parts Required Lower wing panels w/ailerons (L & R) Aileron wire pushrods, 1-5/8-inch (41mm) (2) 2mm x 10mm sheet metal screws (4) Nylon control horn (2) Nylon clevis (2) Silicone keeper (2) Tools Required 1/16-inch drill bit Felt-tipped pen Philips screwdriver #0 Ο 7.
ΟΟ 4. Use a 1/16-inch drill bit in a pin vise to drill the control horn mounting holes. Use care not to drill all the way through the aileron. ΟΟ 5. Apply 2–3 drops of thin CA to each hole to strengthen the wood and prevent the screws vibrating loose.
Ο 2. Using a #1 Philips screwdriver, install the motor mount using the screws supplied with the motor. Use threadlock on the screws to prevent them loosening due to vibration. Ο 4. Connect the three motor wires to the ESC wires. Cowling Installation Parts Required Fuselage assembly Cowling 2mm x 10mm sheet metal screws (4) Cockpit hatch Tools required Pin vise Manila card stock Low-tack masking tape Philips screwdriver #0 1/16-inch drill bit Felt-tipped pen Thin CA Punch or awl Ο 1.
Ο 2. Use a 1/16-inch drill bit in a pin vise to drill a hole in the center of each cowl mounting block. Ο 4. Use low-tack masking tape to tape the alignment tabs to the fuselage with their holes centered over the holes in the cowl mounting blocks. Ο 3. Prepare four 2” x 1/2-inch alignment tabs from manila card stock. At the end of each tab use a punch or an awl to form a hole. Ο 5. Install the cowling on the fuselage, making sure that the alignment tabs are on the outside of the cowl.
Ο 8. Remove the cowling. Use a 1/16-inch drill bit in a pin vise to drill the mounting holes at the marked locations on the cowling. Ο 10. Remove the cowling and apply 1-2 drops of thin CA to each of the mounting holes. We recommend that this be done after the cowl has been mounted and the screws have formed a thread in the blocks. This will prevent them from splitting.
Ο 2. With the fuselage inverted, slide the lower wing panels on to the joiner tube and install the 4-40 x 3/8-inch retaining bolts and #4 washers with a 3/32-inch balldriver. Ο 4.

Connect the throttle lead from the ESC. ΟΟ 3.
Wing Installation Parts Required Fuselage assembly Wing panels on transport jigs (L & R) Upper carbon wing tube, 14-3/8-inch (365mm) Lower carbon wing tube, 10-5/8-inch (270mm) 4-40 x 3/8-inch Allen bolts (4) #4 washers (12) Ο 2. Slide the left and right wing panel assemblies approximately half-way on to the wing tubes, leaving about a 1-1/2-inch gap between the wing and fuselage/center section. Ο 4.
Center of Gravity An important part of preparing the aircraft for flight is properly balancing the model. Caution: Do not inadvertently skip this step! The recommended balance point for the PT-17 is 3-1/4 to 3-3/4 inches (82 to 95mm) behind the leading edge of the upper wing. Mark the range for the Center of Gravity on the underside of the upper wing as shown. Interplane strut removed for clarity.
Control Throws Ο 1. Turn on your transmitter, plug in the motor battery and switch on the receiver power. Make any clevis adjustments necessary to center the control surfaces, then secure all the clevises with the silicone keepers. Ο 2. Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Ο 3. Check the movement of the elevator with the radio system.
