1/30 Scale A330-300 Tail Section - RC EDF

3D model description

Here is the tail section for a 3D printed airliner I am currently designing. The tail will be compatible with the final release of the full airframe. Planning for a release in Summer 2019.

Build log here:

Design is based on a 2-perimeter (0.8mm wall thickness) construction approach to minimize the amount of internal supports needed. I am utilizing ABS as the parts can be welded together with acetone, and weigh ~15% less than PLA

Features include:
-Alignment tabs that provide additional glue surface and easier assembly.
-Built-in servo hatches
-Removable horizontal stabs
-Break-away "Sacrificial base" at bottom of parts to reduce warp/elephant foot for several parts. This is a 15mm section that gets discarded after printing. A light bending will cleanly remove the base from the parts.

All parts can be printing without supports, with the exception of Tail4.

Flip fuselage parts onto build plate so "sacrifical base" are on the build plate.

-6x4x175mm carbon tube is required for the horizontal stabs.
-6x4x190mm carbon tubes (qty 4) are required for attachment to the forward fuselage.
-Dubro nylon hinges required for the rudder and elevators.
-Lightly score with an xacto the servo hatches to release from the parts. A gently prying may be required.

3D printing settings

ABS: 255 degree C nozzle, 80-100 degree C bed. 0.2mm layer height.

All parts can be printing without supports, with the exception of Tail4.
