I am doing a Canadian livery on my Eflite AT-6 and wanted an exhaust pipe to help it look more scale like so I designed this.
Printed @ 20% infill with supports “ touching build plate only”. Print it laying down as shown in the pics. Although not necessary once done you might want to spend a few minutes cleaning it up and then painting it flat black. Mine has not been finished yet but it will be before the plane is done. I used Foam-Tac to attach it to the pipe coming out of the fuse as well as cut a little slot for the attached support and used the same glue for that. After it was completed it added 18 grams to the plane. That's less than an ounce.
EDIT: Cowling and dummy radial can be found here…
