OVERVIEW: This replica of the famous Piper arrow IV is designed for quick and easy construction and printed using light weight PLA (LW-PLA). For best results the canopy should be printed with clear PLA The motor mount and propeller assembly in regular PLA. Designed to suit the 1806 2300kv outrunner on a 2 or 3 blade (5x5) propeller.

ASSEMBLY INSTRUCTIONS After all parts have been printed, some may require to be cleaned as LW-PLA is prone to stringing. Do this by gently sanding back the rough sections with a file, sandpaper or blade until the surface is smooth. All faces which are to be glued to other parts need to be given a light sanding (scuff the surface) to assist with glue adhesion.

Cut 15mm sections of skewer and place into alignment holes in the fuselage sections. NOTE - It may be required to open up the holes a small amount if the fit is too tight. Do this by using a 3mm drill bit. Gently spin it in reverse as you insert it into the hole. This will ensure the bit does not tear the print.

From part “fuse 3” remove the inner section of the lead tunnel with a knife or heated metal rod to allow the servo lead for the aileron to pass through. (refer section marked in red) From fuse 4, remove the section marked in red for the elevator pushrod connecting the bellcrank to the elevator control arm.
Page 9
INSTALLING THE ELEVATOR DRIVE -Cut a 15mm section of 3mm bamboo skewer and test fit it in the bellcrank seat located inside fuse 4. Trim as required to obtain a good fit. Once happy with the fit, cut the same length of 3mm carbon.
Page 10
Fit the elevator bellcrank to fuse 4 with a small amount of hot glue as indicated below. Glue fuse 4 to the remaining fuse sections. Glue the “Vertical stabilizer lower” section to the fuse using the 3mm skewer as a guide. You may need to remove some material from the top of this section where the push rod is required to pass through.

Glue the “elevator races” to the “Vertical stabilizer upper front” section. Be sure that the back edge of the race is square with the “Vertical stabilizer upper front” section. Test fit the 3mm carbon square tube in the elevator control arm. Make sure the fitment is tight.
Page 12
Cut a 100mm length of 3mm square carbon tube and test fit it to the tail section through the elevator control arm. Next feed the small “bearing liners” onto the carbon tube and press them into each race. The bearing liners and races should have a neat fitment with as little play as possible to reduce slop in the elevator.
Page 13
Note the correct neutral position of the elevator control arm relative to the elevator! Glue the sections of the wings together. Glue the wings to the fuselage NOTE – if using 3mm x 0.6mm carbon strip, now is the time to install it.

Run a string through the aileron servo wire tube from the mount hole for the aileron servo to the wing root. Leave enough length so that you will be able to feed the string through the fuse later. Install all servos using a small amount of hot glue to secure them in place. The aileron servos mounting tabs will need to be trimmed.

Place a drop of CA in the hinge slot of the control surface and insert the hinge. Be sure that the hinge is perpendicular to the control surface. Then bend the hinges to 90deg back and forward a few times to make sure they are appropriately loose. See below Glue the rudder and ailerons in place.

RUDDER and ELEVATOR Install the magnets to both the fuselage and the canopy using CA. Place the motor mount in the slot provided on the firewall. Note the orientation of the mount with the small raised sections at the top. Secure it in place with two m2 x10mm screws into the lower holes only.
Page 17
Install the motor to the motor mount. The motor mount holes may need to be pre-drilled with a 3mm drill bit. Secure the motor mount with the final two m2 x10mm screws. The top two screws are first fed from the front of the aircraft through the cowling mounts, then through the firewall and finally through the motor mount.
The holes on either side of the motor slot are for the ESC wires to pass through into the battery compartment of the model. Fit the front cowling to the rear cowling using CA glue. Glue the front and rear section of the canopy together. ** IF NOT USING LANDING GEAR SKIP AHEAD TO STEP 42 ** Cut a 122mm section of 2mm wire and bend according to the diagram below.
SIDE VIEW Fit a 25-30mm foam wheel and secure with an M2 wheel stop collar.

Insert the gear leg into the wing as pictured below. (different aircraft pictured below but the method is the same) Apply a small amount of hot glue to the outer bend of the leg (red circle on image above. This will hold it in place but also allow it to be removed if desired. Fit the wheel and secure it with a shaft collar.

From the fuselage section near the nose, remove the over extrusion lump from the floor. (marked in red) Insert a length of 2mm wire through the nose leg hole and place the nose gear washers over the wire (small washer in the slot on the belly of the model and the larger washer glued to the floor of the battery bay.
Page 22
Cut a mm length of 2mm wire and bend according to the diagram below.
Page 23
Place an M2 wheel stop collar over the top of the nose gear leg and secure the collar with 17mm protruding out the top. The grub screw should also be aligned with the neutral forward position of the gear leg. Then insert the leg into the slot. Press an M2 wheel stop collar into the nose gear steering arm and fit the assembly over the nose gear leg.
Page 24
Connect up the rudder servo with the nose gear steering as pictured below. BALANCING AND CG Fit the battery using Velcro as required and balance the aircraft inverted on the CG marking points located 40mm aft of the leading edge at the wing root. RANGE OF TRAVEL: NORMAL FLIGHT: Elevator...

LAUNCHING: It was found that the safest and most successful launch technique for this model was the under-arm style. The aircraft should be launched at approximately 20deg nose up at 50% to 75% power. Too steep and the aircraft will stall, too shallow and it will contact the ground.
