Giant 1:4,5 scale Heinkel He-162 A2 RC jet model

3D model description

1:4,5 scale model of the Heinkel He-162.

Length: 1996 mm (without pitot tube)
Wingspan: 1580 mm
Flying weight: 7,5 kg
Power: ~4000 W

Minimum printer size for the biggest parts: 280x280x300 mm
Many parts will print on smaller 200x200x180

CG: 83 mm - Should be slightly forward with gear down and slightly aft with gear up
Elevator throw: 20 mm up and down
Aileron throw: 20 mm up and down
Rudder throw: 12 mm left and right
(Note that the prototype did not have reinforced landing gear like the files here. I'm reprinting with the reinforcements)

Very good stall characteristics and gentle handling in flight. The prototype had a top speed of 228 km/h with the 3D printed EDF. There is no bad handling because of the high thrust line because it is compensated for in the design.

The EDF intake is larger than scale for more airflow to the 120 mm EDF. The turbine intake is closer to scale size. I have no intention of trying turbines myself but There is room in the fuselage for all kinds of tanks. I can design a turbine nacelle if there is a need for one with a larger internal cavity than the duct.

Warning, skills like basic metalwork and brazing (silver soldering) is required to finish this model, as well as general model setup know-how. Don't buy this if you don't know how to do DIY stuff like that, or are not willing to figure it out.

Landing gear parts:
Uses retract actuators from JP to retract the landing gear which is integrated:
2x 130 mm shocks:
2x 1,4x10x50 mm springs for the main gear:
0,8x9x60 mm tension spring for the nose gear (I made mine from spring stock)
M5 threaded rod stock and M5 nuts to make actuator lead screws from
Williams Bros 5-1/4 tires can be used instead of the printed tires. Ask WB to sell tires only to avoid having to remove the hub:
Dubro smooth 3-1/4" nose wheel:
4x 47ODx3,5 mm O-rings for the brakes:

Requires the following carbon fiber tubes and rods:
1x 16x14x770 mm tube for the wings
2x 16x14x84 mm tubes for the lower main gear struts
2x 18x16x157 mm tubes for the upper main gear struts
1x 8x6x300 mm tube for the wings
1x 8x6x167 mm tube for the nose gear strut
1x 6x4x900 mm tube for elevator control
Various lengths of 6 mm tube or rod for strengthening the landing gear mount area
Various lengths of 3mm and 4 mm carbon fiber rod for hinging and reinforcement

Various M3 screws and nuts from 8 mm length to 40 mm length
Various M2 screws from 10 to 20 mm length
M3x5 and 12 mm grub screws
M6x80 mm screws for the main gear strut mounts
M6x50 mm hex head bolts for the main wheels

Ball bearings:
12x 6x15x5 mm for the main gear and elevators
4x 4x11x4 mm for the nose gear

3x JX DHV56MG for the nose steering and wheel brakes:
7x Corona CS-238MG (or similar size servo with 4+ kgf/cm torque) for all control surfaces. Flaps and elevator can use standard servos instead:
1x "9g" servo for the nose gear door

Power for the printable EDF unit:
2x 6S 5000 mAh lipos (Gens Ace 45C recommended)
Castle Creations Talon HV 120 ESC
Het 800-73-590kv motor with heatsink:

The stand uses a 16x585 mm tube as the center member. I used locally sourced aluminum tubing. The stand is supposed to support the plane immediately aft of the gear wells and at the joint between Fuselage02 and Fuselage03.

More info will come....

3D printing settings

PLA is fine for all parts. Your mileage may vary due to temperature requirement and personal preference.

As a weight reference, my Fuselage02 weighs 151 g after the two support pieces are removed.

Open the factory file to see recommended print settings for the main parts.

Wings, tail and fuselage main parts should be printed with 0,3 mm wall thickness and single perimeter only. I recommend 0,12 mm layer height. Thicker print width is not recommended due to weight and balance, but 0,4 mm is possible.

Main landing gear and nose landing gear parts should be printed with four perimeters and 10% infill and 0,12 mm layer height. The same goes for links and other small critical parts.

EDF impeller and housing should be printed with 6 top and bottom layers and 7 perimeters.
