Description

3D MODEL DESCRIPTION

Designed by Nakajima as the Army Type 4 Fighter, the Ki-84 is generally considered the best Japanese fighter to operate in large numbers during the conflict, with high speed, excellent maneuverability, and formidable firepower - up to two 30 mm and two 20 mm cannon. Almost 3,500 were built.
https://en.wikipedia.org/wiki/Nakajima_Ki-84
This 600mm wingspan version is powered by a BR2205 2300Kv or a low cost QM2804 2300Kv or similar electric out-runner and is designed to be printed in LW-PLA, with a few key parts in PLA, like the motor mount, propeller blades and hub.

Included with this file:
• Factory files for Simplify3D
• STL files for all components
• Assembly manual and user guide
• Sample markings

UPDATES
2021-09-18: BR2205 + 5x5 e-prop + 3S 550mAh is the best combo; lesser torque side effect, easy hand-launch, better than 1:1 power to weight ratio.
2021-06-08: v1.5
• All the key parts now printing in a continuous motion to reduce/eliminate those LW-PLA twisters: F1, F2, F3, Wings, Stab, Hatch.
• Factory files improved; end script, start point, firmware type updated/corrected
• 2mm round toothpicks can be added to stiffen the stab
• Magnets to retain hatch increased to 6x2mm
• Stiffener added to hatch back magnet
• Trailing edge wing fillets added
2021-05-19: CG at 31mm on flying prototype
2021-05-16: Successful test flight! Needs stronger magnets to hold down the hatch. Fast on the BR2205 / 2S 1300mAh.
2021-01-29: New thinner Propeller Hub
2021-02-01: Updated Fuse3c with a thinner central rib to match the other internal formers and fixed the location of the hole through Fuse3c for the elevator joiner.
2021-02-05: Updated F3d.stl with a better front end, making for a cleaner print.

3D PRINTING SETTINGS

LW-PLA parts;
• print head = 250 deg c
• print bed = 60 deg c
Cooling fan to be run for each layer at 100%; I start around layer 4 for better adhesion to the bed.
The Wing panels are tall at 248.5m and printed in one piece without the wing tips; the wing extremities could end up wavy from wobbling during the print. This can be solved by printing the Braces with them.
