A6M2 Zero Model Aircraft, designed by 3Dlabprint.
This aircraft is designed for 3D printing with LW-PLA. A model with 100cm wingspan that can be controlled by a 4-channel remote control.
The filament I use: Esun brand LW-PLA
Printers I use: Org. Prusa MK3S+ and Artillery Genius
The values I give should be considered as a reference. Different results can be obtained in filament and other brand and model machines.
The wall thickness of the pieces I printed was between 0.6 and 0.68.
In the factory files of the company, the nozzle temperature for LW-PLA is 230 °C. Since I could not obtain the correct wall thickness with this value, I printed all the parts at 239 °C.
Flow is 56-57 for fuselage parts, 50-51 for wing.
The tail of the scale versions of Zero RC models is usually heavy. Therefore, it is necessary to put extra weight on the nose part. If you do not want to use additional weights in this model, you have two options.
1- Using a higher capacity 3S battery (like 2200mah) or 4S battery.
2- Printing the tail pieces lighter and moving the motor mount 7-9 mm forward.
I chose the 2nd method because I want to use a 3S 1550 mAh battery. For body parts, I usually applied 56-57 as flow value.
But for the parts of the tail, I applied the flow value as 49.
The body and tail parts I want to lighten:
Fuselage 5, 4 and 3
All stabilizer and elevator parts
When I printing in this way, I was able to lighten the rear part of the body by about 14 g. And I extended the motor mount 8mm. As a result, I got the right center of gravity without using extra weight with the 3S 1550 mAh battery.
With Emax XA2212 1400KV motor, 8×6 slow flyer propeller, ZTW 30A ESC, Gens 11.1V 1550mAh lipo battery, 3 MG90D micro servos, the total flight weight was 622 gr.
With this equipment and weight, the flight time is 9-14 minutes (Depends on the usage style).
