A 3D printed version of the famous Stinger400 created some 20 years ago by S. Sobayakin.
You can print and fly this ultimate pylon racer for under 250g. Choose between a small out-runner or an in-runner setup.
With a 60w 1806, you get a nice little sport plane. On a low cost 175w at 250g, you get a blistering little bugger and still a nice and easy landing.
Use a pair of 3mm bamboo skewers for spars or carbon rods for a high performance setup.
Included with this "kit”:
• 3mf files provided for Cura users (4.13.1)
• Factory files for Simplify3D
• STL files for all components
• Assembly manual and user guide
UPDATES:
2022-11-23: Updated Cura files; most parts are symmetrical and need to be mirrored in your slicer except for W1R-1Servo.stl. Also, WingletLstl sported a small error.
2021-08-02: Added support for QM2804 out-runner on 3S and 4.75x4.75 prop, including spinner. Fast!
2022-02-20: Updated start scripts and now all parts
fit into a limited printer volume.

Print time: 30hrs
Print weight: 110g
RTF AUW: 215g-235g with gear listed below installed.
REQUIRED COMPONENTS:
X1 1806 2300Kv out-runner Motor (or similar) / BL2040 3900Kv in-runner
X1 20AMP ESC
X1 900mAh-1300MAH 2S LIPO (or similar), 59g
X1 4ch+ Micro Receiver
X3 3mm Bamboo Skewers / 3mm Carbon Rods
CA Hinge Sheet or X8 Micro Hinges
Velcro (sticky back)
Some 1mm music wire for pushrods.
X2 M2.5 screws to attach the 2040 in-runner
For a 2 servos wing:
X3 3.7g Micro Servo
For 1 central servo hidden inside the fuselage:
X1 3.7g Micro Servo
X1 9g Micro Servo
PRINT OPTIONS
2 different noses
A- small back-mounted drone out-runner (1806, 2804, BR2205).
B- small front-mounted in-runner
2 wing/servo options
A- 2x 3.7g with 1 servo in each wing, partially sticking out in the breeze
B- 1x 9g central servo with a rocker drive
PRINT VOLUME:
200x200x250
300x300x380
All the parts will fit in a 200x200x200 printer
now. Following demands, I figured a way to split F3 and still have a compact
way to align the 2 parts. The original F3 at 272mm is still available. I recommend printing one part at a time for best resulting parts.

3D PRINTING SETTINGS
PLA+
I used Ingeo 3D850 PLA from local Materio3D filament manufacturer.
• print head = 230 deg C
• print bed = 60 deg C
No cooling fan will provide better layer adhesion.
The tall and thin pieces might be wobbling during the print. Scalloped braces have been provided for optimum printing quality.
