VJet OWL
VJet OWL Flying Videos and Pictures
This cool looking plane flies more like EDF trainer plane. With V shape tail and powered with 70mm EDF, it takes off from land. There is no steering wheel but it is enough to get the plane flying and landing smoothly. It has detachable wings to make it easy for transport. Fiber carbon tubes are optional to use but ready if you would like to use them including two 5mm OD fiber carbon tube inside the fuselage. Landing gears without skirts are also an option if you feel better to use in your flying fields. You can fly it as a sport or aerobatic plane.
Do you want to hand launch VJet OWL ? no problem, 2 STL files are updated to the repository so that you can close the landing gear position area on the Fuselage Part. More details, just find the Update Section in this page.

Center of Gravity (CoG) :
- CoG is 65mm from Wing Root Leading Edge.
- During maiden, please allow 3 - 4mm toward the nose (forward), start with more solid flying and adjust gradually during the next flight.
Weight and Time Estimation :
Following tables show the weight of printed parts, number of required filament rolls and time required to print. The numbers are taken from ideaMaker slicer calculation. From experience, actual numbers show about -5% less than depicted in the table. But the number may vary from printer to printer due to:
– Stepper Jerk value.
– Stepper Acceleration value.
– Steps per unit (either calibrated or uncalibrated)
– Extruder quality/condition.
– Nozzle quality/condition.
– Filament quality/condition.
– Etc.
For sure the relative number are useful when deciding to accept the total strengths or weights when printing. Picking higher strength to some parts are necessary to avoid breaking during high impact landing or sharp maneuver for example.
Here are the summary tables:

Update History
History Summary:
Version : 1.2 – Introduced Wing Spar as an Option / Supporting Using LW-PLA/ePLA-LW Filament for Wing Parts.
Version : 1.1 – Introduced Twin Carbon Tubes to Strengthen Tail Parts as an Option / Supporting LW-PLA/ePLA-LW Filament for Some Tail Parts.
Details, scroll down to the two sections below.
Update from version 1.0 (Released as Version 1.1)
Updated on May 3rd, 2021
Feel free to use 5mm OD carbon tube to strengthen Fuselage-4 to Fuselage 7.
STLs and G-code are already updated into VJet purchased repository and ready to download.

Update from version 1.1 (Released as Version 1.2)
Updated on May 4th, 2021
Introducing 8mm OD carbon tube to strengthen the wing parts (used as spar).
a. carbon tube 8mm OD 1 meter long or
b. 2x carbon tube 8mm OD 500mm long.
When using (a), all the wing parts can be printed using LW-PLA.
When using (b), suggest to print “WING-L-1 # P3_H15 and WING-R-1 # P3_H15” parts in PLA and remaining in LW-PLA.
STLs and G-code are already updated into VJet repository and ready to download.

Refer to the images above for the spar location. For more wing assembly details, please refer to the ASSEMBLY website pages.
Note: avoid to glue the spar/carbon tubes so that it can be easily removed later when trying to reuse it
Update from version 1.2 (Released as Version 1.3)
Updated on October 5th, 2021
Providing larger wheels and no shell main landing gears for grass friendly runaways.
Update from version 1.3 (Released as Version 1.4)
Updated on December 11th, 2021
2 STL files are added to use if you decide to hand launch the plane.
They are :

– NO-LG-B # GR3
Update from version 1.4 (Released as Version 1.5)
Updated on December 17th, 2021
Updated the following files for strengthening tail parts.
They are :
– FUSELAGE-7 # P3_H15 for both options (with fiber carbon tube or without)
– VTAIL-BASE-L-1 # P3_H15
– VTAIL-BASE-L-2 # P3_H15
– VTAIL-BASE-R-1 # P3_H15
– VTAIL-BASE-R-2 # P3_H15
Updated the following file for stronger EDF-HATCH part required for hand launching.
They are :

Recommended Setup
- Motor Options : EDF 70mm, 4s (possible with 6s but not yet tested), see above for some options but not limited to.
- Servo Options : 12gr Servos, 2 x for left and right aileron and 2 x for left and right stabilizers, see above for some options but not limited to.
- ESC Options : ESC with 80A, just pick your favorite ESC but make sure that rated at least 80A.
- Battery Size : LiPo 4s 2200mah - 2700mah.
Tools and Materials
- Printer, in general 200mm x 200mm x 200mm (W x L x H) for all OWLplane Models.
- Filament such as PLA, ABS, HIPS and ASA (do not use silk PLA, it tends to be very weak in layer to layer adhesion).
- CA glue with accelerator. Use thick glue to join surface to surface. Use thin CA glue for coating the joint surface areas.
- Velcro sticker/polyester hook and loop peel-n-stick self-adhesive for positioning and locking the battery.
- Fine sandpaper.
- Sharp knife.
- Screwdriver and/or allen wrench for chosen screws/bolts.
- Pliers, needle-nose pliers, nippers.
- Steel bolt cutter.
- Dremel/rotary tool for cutting carbon fiber tubes and rod with more than 2.5mm.
- Electric drill, its drill-bit size from 1.5mm - 5mm and step cone drill.
OWLplane Printers (for your ref.)
See figures below some printers used, created, developed and modified by OWLplane. Two group printers are set, the first one is utilized only for printing PLA/PLA+ and the other one is utilized to print with ABS, ASA and HIPS filaments (the one with enclosures). Just hover onto the figures to find more information about them.
Modified all Bowden setup printers into Direct Drive but leave Tevo Tornado and Anycubic Mega as is (still in bowden setup).
