Description
The North American Aviation XB-70 Valkyrie was the prototype version of the planned B-70 supersonic bomber for the United States Air Force. Two prototypes were build, one of which (No. 2) was destroyed in a mid-air collision. No. 1 is on display at the Wright-Patterson USAF Museum.
This printable model I created is just a very rough model, specifically designed for easy 3d-printing. It has to be glued together (please see post-printing section).
Dimensions: length: 160mm wing span: 67mm height (assembled): 56mm
Scale: 1:375
The folding wing tips can be printed flat (with Curas lay flat option in the rotate menu on the left).
Printer:
Anycubic i3 Mega
Resolution:
0.1 (0.2) mm
Infill:
25%
Filament:
FormFutura (unknown) PETG/HDglass (PLA) blended white (RAL 9005 black)
Notes:
The afterburners and the stand were printed with black PLA with a resulution of 0.2 mm.
The main hull/fuselage, wings and canards were printed with white PETG with a resulution of 0.1 mm.
Glue Everything Together:
Usually you can glue all the parts immediately together, without a lot of reworking. I recommed using superglue or instant glue.
The engines part slots right into the main hull part.
The engine vent is to be glued under the tip of the inlet.
The afterburners go at the rear of the engines. But maybe you have to sand the edges a bit to make them fit respectively make the engines fit under the fuselage without a gap.
The canards have to be glued behind the cockpit windshield (as shown in the picture).
The wingtips have to be glued at an 65° angle.
And the stand has to be glued in the center of gravity. To find the center of gravity, simply balance the fully assembled plane on the tip of your finger. The perfect position for the stand is found, if the nose of the plane pitches slightly upwards.
