Videos and Pictures
If you do not want to get hassle preparing an rc jet plane at the flying field after arriving (all already well prepared at home)… just grab the plane, put the battery in, throw it and fly. Woooooss… from left ….woos from right and the total cost to build is relatively cheap, this 3d printed rc plane may be your best choice. With cool looking shape copying form BAE Hawk T1 model, this OWL BAE Hawk T1 not only fly great but also beautiful in the air. It is considered as semi scale plane. For the wings, it is your choice that you can permanently attaching the wings into the fuselage by gluing them for more solid attachment (suggest to bring CA glue with you in case the wing attachment parts get broken after hard landing).
This model must be printed with LW-PLA/ePLA-LW/PolyLight 1.0 filament only.
Please note that G-code files generated from ideaMaker does not compatible to use with Prusa original 3D printers. Please use Cura or S3D instead if you would like to regenerate the G-code files for your Prusa printers.
Suggestion, please see the following video to throw this model. It has more WCL value than L-39. With using bodyweight to throw, we never fail to launch the model.
We would suggest to use OWLplane Catapult Launcher for launching the model (no human errors). If you use to hand launch rc plane models, ask someone else to help launching during maiden (controlling and throwing the model are conducted by different persons) !
Fyi, it is easier to hand launch OWL L-39 model compare to OWL BAE Hawk T1 model (due to lower WCL value). But after flying in the air, it will scream :).

Aileron/Wing Control Surfaces Rods:
Elevator/Horizontal Stabilizer Control Surfaces Rods:
Electronic Position :
Feel free to position the electronics to get the correct CoG.
EDF Installation and Canopy Trim :
Center of Gravity (CoG) :
- CoG is 73mm from Wing Root Leading Edge.
Launching with OWLplane Catapult Launcher :
Please visit OWLplane Catapult Launcher product page under “PRODUCTS” tab after clicking “ALL PRODUCTS”. You may want to download and print the 3D printed parts.
If you plan to launch the model with your own catapult launcher, you may still want to download the model hook profile adapter from OWLplane Catapult Launcher repository/product and its free.
How to Hand Launch OWL BAE Hawk T1 50mm EDF Model :
Follow the following tips to launch :
– Lean your body backward.
– Use 3 finger grip to launch.
– Start throwing by also moving your body forward.
Please Use 3-Point-Grip Protectors as Follow (Optional but Recommended to Use) :
The name for STL files are :
– GRIP-PROTECTOR-F-L # GR2.
– GRIP-PROTECTOR-F-L # GR2.
– GRIP-PROTECTOR-B # GR2.
Why need to use and what suggested filament type:
– When strongly pinching the grips, it may break the skin of the model.
– Need to print with PLA (better than LW-PLA) for having strong protector.
Just ignore rough surface, it is not sanded yet.
Sand The Surfaces To Get Smooth Ones :
Weight and Time Estimation :
Following tables show the weight of printed parts, number of required filament rolls and time required to print. 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.

Recommended Setup
- Motor Options : 50mm EDF 4s shown above (it is possible to use 3s 50mm EDF and run with 4s only but you may need to use 50A ESC and manage the throttle not full all the time. It will be very useful during hand launch * easier to launch the model * ) .
- Servo Options : 2 x 12gr servos for aileron (left and right) and 2 x 12gr servos for elevator. 9gr servos may be enough but 12gr will have more room when need excessive force during flying.
- ESC Options : ESC may be enough with 40A but better to use 50A (cooler).
- Battery Size : LiPo 4s 1500mAh - 1800mAh (please use ESC location to get the correct CoG).
Tools and Materials
- Printer, in general 200mm x 200mm x 200mm (W x L x H) for all OWLplane Models.
- Filament: LW-PLA from ColorFabb, ePLA-LW from eSUN and PolyLight 1.0 from 3DLabPrint.
- 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 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.
- Propeller shaft reamer or hole puncher reamer.
Hardware Needed
For Fuselage and Canopy:
- Self tapping screw M3x25mm or M2.5x25mm with their washers (optional) for mounting left and right wings including fuselage lid - 4x.
- Ballpoint pen springs for Canopy - 1x.
For Aileron and Elevator Servos:
- 1mm - 1.2mm rod for aileron and elevator hinges (ER308L - TIG Stainless Steel Rod or Aluminum).
- 1mm - 1.2mm rod for aileron and elevator pushrod (ER308L - TIG Stainless Steel Rod).
- Landing gear wheel stop set collar 9x1.6mm for aileron and elevator - 4x.
- Linkage stopper D1.6mm for for flap, aileron, rudder and elevator - 4x.
- 1.5mm-1.6mm OD fiber carbon or aluminum rod for creating support rods. inside control surfaces parts.
