Files of the wing, landing gear, stabilizer, engine nacelle marked " L " for printing the right parts of the aircraft should be in the slicer mirror. The fuselage 2 marked V. 2 has an extended part of the cargo hatch for easy battery placement.
Attention, the wing chord is designed to scale as in the original, so the load will be significant. The flight weight of the aircraft (with 2200mAh battery) must not exceed 1400 grams.

PLA: recommended print speed is 60 mm / s with a maximum print height of 0.18 mm. Nozzle temperature 210-220 degrees, table 60 degrees. You usually don't need to install support, but it depends on your printer settings.
