Printing thin-wall models¶

Desktop 3D printers are perfectly capable of producing great-flying R/C models durable enough to withstand hangar rash and general use. However, aircraft designs contain a unique mix of thin surfaces and intricate solid supports that require some practice to print perfectly. Keep the following tips in mind when printing your model.

Slicing with OrcaSlicer¶

The model download includes .3MF project files for OrcaSlicer – a modern, free, and open source slicer with wide support for popular printers and the ability to utilize multiple plates and varying settings within a single project. These project files include print settings tailored to the model as well as filament settings with adjusted temperature and retractions. The provided settings have been tested to suit a wide range of printers – in most cases, no changes should be necessary aside from choosing your printer.

The video below provides a guide for opening the .3MF project files in OrcaSlicer and ensuring the included process and filament settings are applied properly.

Tutorial video¶

Modifiers and per-object settings¶

OrcaSlicer allows per-object modifications to slicing settings, and this method is frequently used in the provided .3MF files. When making settings changes, be mindful of these per-object settings as well as any height range or other modifiers that have been applied to each part. You can use the "View all object's settings" button to quickly view the modifications for all part files in each project.

Quality filament¶

Using good quality filament can be the key to successful thin-wall prints. Foaming LW-PLA is the filament of choice for these prints due to its low warp and high interlayer bond strength – but not all LW-PLA is created equally. With poor quality filament, you may notice surface imperfections, underextrusion, or inconsistent foaming. We've had the best results with 3DLabPrint's "PolyLight" LW-PLA and strongly recommend it for printing Lofted Aero models. If it's not available in your region, Colorfabb's LW-PLA is a good substitute. Bambu PLA Aero will produce acceptable results, but weight and surface finish tend to be worse than the 3DLabPrint or Colorfabb materials.

Preparation¶

Print the templates on large-format plotter paper. Adhere them to foam board with a light dusting of spray adhesive. They should fit on three 20" x 30" sheets.
Cut out the lower fuselage shell. For the double sets of lines between the bottom face and side panels of the part, only cut about halfway through the foam.
Remove the paper template from those areas.
Cut out all remaining foam parts.

Wing assembly¶

Using UHU-Por, Foam-Tac, or epoxy, laminate the parts shown.
Similarly, laminate the side doublers of the forward wing section.
Laminate the upper doublers onto each wing panel.
Bevel the leading edges of the wing on both the top and bottom.
Apply strapping tape to the bottom front and top aft spar areas of the wing panels as shown.
Cut the 119mm forward spars and 37mm aft spars from 10mm carbon square tube. Glue them into their slots in the wings, pressed down against the strapping tape. The aft spars will protrude from the underside since the lower wing doublers have not yet been installed.
Cover the top side of the forward spars with strapping tape.
Wrap another piece of strapping tape around the beveled leading edge of each wing.
Glue the two lower wing doubler parts to the underside of each wing, surrounding the aft wing spars.
Cover the bottom of the aft wing spar with a piece of strapping tape.
Cut the 76mm forward and 110mm aft spar joiners from 8mm carbon tube. Glue them into the wing spars using CA. The forward joiners should protrude 39mm from the edge of the wing spars, while the aft joiners should protrude 72mm from the edge of the wing spars.
Glue the roll thruster housings into their cutouts in the wing panels.
Cut the 287mm center spar section from 10mm square carbon tube. Use the main gear mounts as a guide to drill 3.2mm clearance holes for the M3 spar bolts.
Place a piece of strapping tape along the underside of the forward center wing section.
Use the strapping tape to join the forward center wing section, center spar, and aft center sections.
Wrap and trim the tape on the underside of the center section as shown.
Spread the spar and foam apart and apply epoxy to the contact surfaces. Rest the part flat while curing.
Once the glue has cured, cover the areas shown with strapping tape.
Use a pencil to mark the locations of the carbon square fuselage spars. They should be 119mm apart – flush with the edges of the cutout in the aft fuselage.
Use UHU-Por, Foam-Tac, or epoxy to glue the carbon fuselage spars to the underside of the assembled center section. The front of the spars should be flush with the lip at the corners of the inlets – protruding 10.5mm ahead of the cutout for the lift fan mounts.
Laminate the three lower fuselage doubler components to each side of the underside of the center section as shown.
Use epoxy to attach the main gear mounts to the spar and underside of the center section.

Lower fuselage assembly¶

Trim the hatch cutout as needed. Hinge it on the underside with a piece of strapping tape.
Fold the hatch over, then hinge the inner side with strapping tape as well.
Add some scrap strips of foam to the inside of the hatch to support it when closed. Be sure to only glue these strips to the lower fuselage shell, not to the hatch itself.
Keep the hatch closed for now with a strip of masking tape on the outside.
Carefully peel away the foam interior strips along the seams between the sides and bottom of the lower fuselage shell.
Use hot glue to fix the middle side panels upright, perpendicular to the bottom. The edges of the side panels should rest beside the bottom panel, not on top of it.
Glue the solid triangular wedges to the aft edges of the front side panels, and the notched triangular wedges to the forward edges of the aft side panels.
Fold the forward side panels into place and attach with hot glue, using the triangular wedges to set the angle. Use a straightedge to press a crease into the inlet portions in order to bend them inwards.
Fold the aft side panels into place and attach with hot glue, using the triangular wedges to set the angle. Use a straightedge to press a crease where the aft and middle sections meet such that the entire assembly can be placed flat.
Glue the completed lower fuselage shell to the underside of the center section assembly.
Reinforce the forward and aft edges with strapping tape.
Install the spacer wedges between the rear of the lower fuselage and the carbon fuselage spars.

Upper fuselage assembly¶

Use CA to glue the 3BSM mounts and rear brace to the carbon fuselage spars.
Cut the 72mm rear spar receptacles from 10mm square carbon tube and glue with epoxy.
Cover the rear spar receptacles with strapping tape and trim as necessary.
Glue the cooling vents into their holes in the center section.
Use CA to glue together the two upper fuselage sections. Trim the corners shown in order for the parts to interlock properly.
Use epoxy to glue the upper fuselage to the center section.
Use a sharp hobby knife to carefully cut away the hatch opening.
Insert a pen spring and the hatch latch into the forward hatch section. Then, glue the two sections of the hatch together. Ensure that the hatch latch can slide freely.
Glue the upper fan doubler to the forward section of the upper fuselage.
Trim the circular fan cutout area.
Dry fit the wings and drill clearance holes for the forward and aft spar bolts.
Glue the top reinforcement plates above the landing gear mounts on either side.
Install threaded inserts in the top of the forward and aft 3BSM mounts.
Install threaded inserts in the underside of the aft 3BSM mount, used for capturing the rear wing bolts.
Install five threaded inserts in each main gear mount.

Nose assembly¶

Glue the three nose sections together as shown.
Glue the upper fan doubler to the aft section of the nose assembly.
Cut out the circular fan mounting area.
Drill clearance holes for the upper and lower nose mounting screws as shown.
Cut two 55mm lengths of 8mm carbon tube. Drill M3 clearance holes centered 7.5mm from one end. Glue these tubes into the carbon square fuselage spars, protruding 15mm from the front.
Cut two 55mm lengths of 5/16" (8mm) wood square dowel. Use CA to glue them into the upper fuselage.
Install six threaded inserts in the nose gear mount.
Install a threaded insert in each lift fan mount.
Slide the lift fan mounts over the square carbon fuselage spars and the square dowel joiners.
Slide the nose gear mount over the round carbon tube joiners in the nose. The holes in the tubes should align with the threaded inserts in the mount.
Slide the nose over the nose gear mount and onto the square wood joiners. Ensure that the aft edge of the nose properly interlocks with the forward edge of the upper fuselage.
Use two M3 x 20mm cap screws to secure the underside of the nose. These screws should pass through the nose gear mount and carbon tube joiners and engage the threaded insert on the opposite side.
Use two #2 x 5/16" self-tapping screws to secure the top of the nose to the wood square dowels.

Control surfaces and tail assembly¶

Use CA to install the stabilator hinge inserts into their pockets in the aft fuselage stiffeners. Use a section of pushrod to keep the hinge axis aligned while glue cures.
Use CA to attach the stabilator control horns to the stabilator stiffeners in the orientation shown.
Use epoxy to join the stabilator stiffener and control horn assemblies to the foam stabilators. Wrap a thin piece of strapping tape around the leading edge of each stabilator.
Use epoxy to install the aft fuselage stiffeners over the foam and carbon fuselage components.
Install two threaded inserts in each vertical tail base.
Use epoxy to mount the vertical tail bases to the aft fuselage. Ensure that they're parallel and aligned.

Battery hatch assembly¶

Slide the battery hatch latch into the holder along with a pen spring.
Glue the small round latch tab into place, securing the assembly.
Glue the completed hatch latch assembly into the foam battery hatch panel and reinforce with tape.
Glue the battery hatch latch receptacle into the cutout in the underside of the fuselage.

Finishing touches¶

The wings slide into place and secure with four M3 x 20mm cap screws. The verticals secure with four M3 x 16mm cap screws – punch holes for these to pass through the foam. With the airframe complete, it's a great time to paint your model if desired.

Landing gear installation¶

Use the printed guide to bend 3mm or 1/8" steel rod into the shape of the landing gear struts.
Grind flat spots to engage the set screws on the brass shaft couplers.
If necessary, extend the flat spots on the retract units to also accommodate the couplers.
Use the couplers to install the steel struts onto the retract units.
Install the wheels using 1/8" shaft collars on either side.
Mount the nose retract unit using four M3 x 6mm flat head screws. Install the nose steering servo with two #2 x 5/16" screws and washers plus a steel pushrod.
Mount the main retract units using four M3 x 6mm flat head screws each.

Power system installation¶

Follow the 3BSM video guide series to assemble the 3BSM. While the guide details assembly of the 90mm version, the 70mm version is nearly identical. There are just six screws/bearings per ring instead of eight.
When using the 3BSM configuration app to set up the controller board, be sure to select the defaults for the 70mm size 3BSM when prompted. This sets the gear ratio and homing parameters appropriately.
Use four M3 x 10mm socket head screws and washers to mount the completed 3BSM and the fan onto its mounts.
Extend the wires on the roll thruster motors as shown.
Use some of the screws included with the roll motors to mount them to the roll thruster housings.
Pass the roll thruster motor wires through the mounts and install an MR30 connector on each.
Slide the lift fan exhaust duct onto the aft edge of the lift fan. The "shelf" on the bottom of the duct should face aft.
Remove the nose and nose gear mount. Attach the lift fan to its mounts with two M3 x 10mm socket head screws and washers. Also use two self-tapping screws to secure the exhaust duct to the lift fan mounts.

Servo installation¶

Use #2 x 5/16" self-tapping screws and washers to attach each stabilator servo to its mount plate. Center and install the servo arms.
Scuff or remove the paint in the areas where the servo mount plates will attach. Scoring the paper covering the foam helps as well.
Use epoxy to glue the servo and mount plate assemblies in the location shown.
Connect the stabilators with pushrods and EZ-Connectors as shown.

Ports and functions – Matek H743-Wing or TBS Lucid H7 Wing¶

The recommended configuration uses the ports and connection scheme detailed below. If you wish to change sensors or output assignments, refer to the ArduPilot wiki to ensure that parameters are updated accordingly. The firmware flashing process is different – here's a useful video guide: Installing ArduPilot on an H743 Flight Controller.

Servos and motors¶

Device	Autopilot Port
Lift Fan ESC	S1 (SERVO1)
Main Fan ESC	S2 (SERVO2)
Right Stabilator Servo	S5 (SERVO5)
Left Stabilator Servo	S6 (SERVO6)
3BSM Controller Yaw	S7 (SERVO7)
3BSM Controller Tilt	S8 (SERVO8)
Electric Retracts	S9 (SERVO9)
Nose Steering Servo	S10 (SERVO10)
Right Roll ESC	S11 (SERVO11)
Left Roll ESC	S12 (SERVO12)

Sensors and peripherals¶

Device	Autopilot Port
R/C Receiver	RX6 (if using PPM or S.BUS), TX6 (if using SRXL/DSM)
GPS/GNSS	CAN1 (if using CAN), TX2 RX2 DA1 CL1 (if using Serial + I2C)
Telemetry Radio	RX7 TX7 RTS7 CTS7

Power¶

Device	Input	Output
BAT 8-36V Pads on H743	6S from main batteries	None
H743 Servo Power (Vx)	Set to 7.2V by soldering jumper pad. Refer to Matek documentation.	—

Note

Requires all servos to be HV capable!
Do not connect ESC BEC (red wire) to H743, since it has a built-in regulator to power the servos.
Power main ESCs direct from battery, not from BAT/ESC pads. The current draw is too high for the H743.

7.2V servo power and 5V power harnesses¶

Solder the 7.2V jumper on the H743-Wing. This will provide 7.2V to the "Vx" rail, allowing for faster servo responses that particularly benefit 3BSM performance.
Since the retracts must run from 5V but the H743 is configured to output 7.2V to servos, prepare a 3-way Y-harness with the red power input lead separated. Plug the red BEC lead from one 80A ESC into this lead, while the signal and ground connect to the flight controller.
Similarly, prepare a male-to-male extension for the 3BSM controller board that splits the power leads into a separate connector. The 3-pin end of this lead should connect to S7 on the flight controller. The lone signal lead should plug into the rudder input of the 3BSM board, while the power end should plug into one set of the servo power pins on the 3BSM board. This will provide Vx (7.2V) to the servos.
Lastly, the second male-to-male extension for the 3BSM controller board should have its red lead split off into a receptacle. This should connect to the red BEC lead from the second 80A ESC, while the signal and ground connect to S8 on the flight controller. The complete 3-pin end should connect to the 3BSM controller's transition input pins. This will provide 5V power to the 3BSM controller board in addition to the tilt signal.

Avionics installation¶

Extend the motor leads on one of the 80A ESCs to the length shown for the lift fan.
Solder the two main ESCs together with wires of the length shown. Use a length of 10AWG wire for the battery input and a length of 16AWG wire which will connect to the flight controller.
Cut a hole for the battery connector to enter the battery hatch area. Reinforce with strapping tape.
Use double-sided tape and zip ties to attach the ESCs to the fuselage spars. Pass the battery connector through the hole.
Prepare two MR30 connectors with 22AWG leads for the roll ESCs.
Solder the MR30 connectors to the roll ESCs. Connect them to the flight controller with 16AWG wire.
Solder the 16AWG battery input leads to the flight controller.
Re-stack the flight controller, then use double-sided tape to fix it inside the fuselage. Use one of the battery strap holders to set the spacing. You may wish to load firmware and calibrate before mounting.
Use double-sided tape to adhere the roll ESCs just inboard of the main gear. It may be helpful to temporarily remove the retract units.
Dry-fit the wing panels and secure the roll motor leads with strapping tape.
Secure the various leads from the 3BSM servos and control board with cable ties. Ensure that there is enough to allow for the entire range of motion of the 3BSM.
Make a cable to connect the GPS module with a 6-pin JST-GH connector on one end and header pins on the other. Refer to the Matek pinout diagrams.
Use double-sided foam tape to attach the GPS module to the nosegear mount in the position shown.
Use cable ties to secure the GPS cable along with cables for the nose retract and steering servo.
Connect the remaining wiring using the provided diagram. Tidy and secure with cable ties. Glue in the second battery strap holder.
Mount the flight controller's USB extension to an accessible location in the upper fuselage.
Mount the R/C receiver to an open area inside the lower fuselage.
If using a telemetry radio, it can be mounted in the lower fuselage as well. It's a good idea to mount it as far from the R/C receiver and GPS as possible.

Setup & finishing¶

Refer to the flight controller setup video to load firmware, perform calibrations, and configure ArduPilot for flight. Setup for the 70mm model is the same as the 90mm – just with elevons instead of separate aileron and elevator surfaces and no flaps. See also the Firmware Flashing Guide for ArduPilot on the Matek H743-Wing.

As mentioned in the video guide, adjust control deflections using the suggested throws below. It is VERY important that throws match these suggestions, as the default stabilization gains will be incorrect otherwise. Dual rates and trim should not be used, as this can interfere with the flight controller's functions in assisted modes. Regardless, consider using 25% - 50% expo for a smooth control response.

Match these throws exactly

Control (measured at forward-most tip vs. fuselage)	Travel
Stabilator — Roll	22 mm up / 22 mm down
Stabilator — Pitch	22 mm up / 22 mm down

The recommended CG is located at the mark shown, 85mm to 95mm behind the leading edge of the wings at the root. Ensure that the model balances at this location with the battery, electronics, and all hatches installed. The landing gear should be extended during balancing.

Recommended CG location

Please consider also operating the model in RealFlight, as described in the following video. This simulator runs real ArduPilot firmware and interacts with Mission Planner just like the real model would. Mastering the simulator model is a great way to prepare for the first flights. Again, the 70mm model is effectively the same as the 90mm model shown in the video guide.

Secure the battery with hook and loop straps.
