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

cults3d

I am currently designing a 3D printed airliner, and I am excited to share its tail section with you. This design is compatible with the final release of the full airframe, which is planned for Summer 2019. You can view my build log here: https://www.rcgroups.com/forums/showthread.php?3117172-1-30-Scale-Airbus-A330-300-(3D-Printed) My design approach involves a 2-perimeter (0.8mm wall thickness) construction method to minimize the number of internal supports needed. I am using ABS, as it can be welded together with acetone and weighs about 15% less than PLA. This airliner features several exciting components: * Alignment tabs that provide additional glue surface and make assembly easier * Built-in servo hatches for convenient access * Removable horizontal stabs for increased flexibility * A break-away "Sacrificial base" at the bottom of parts to reduce warp/elephant foot, which is a 15mm section that gets discarded after printing. This base can be cleanly removed from the parts with a light bending motion. All parts can be printed without supports, except for Tail4. To minimize warping, I recommend flipping fuselage parts onto the build plate so the "sacrifical base" are on the build plate. Here's what you'll need to complete this project: * 6x4x175mm carbon tube for the horizontal stabs * 6x4x190mm carbon tubes (qty 4) for attachment to the forward fuselage * Dubro nylon hinges for the rudder and elevators * Lightly score the servo hatches with an xacto knife to release them from the parts. A gentle prying motion may be required. Edit: I added Prusa Gcodes on November 28, 2019.
