After seeing Joshua Cameron's Mini RC Wing: https://www.thingiverse.com/thing:2781182, I decided to use the same techniques to make a larger dual boom aircraft which would be able to carry FPV gear better and support more powerful power systems.

To print this model you will need the following 3D printed parts:
1x Left wing
1x Left Aileron
1x Right wing
1x Right Aileron
1x Horizontal stab
1x Elevator
1x Cockpit or FPV Cockpit
1x Fuselage front
1x Fuselage rear
2x Spar
2x Vert Stab

You will also need:
1x 1507 or similar motor
1x 15a ESC, dependent on your motor
3x 3.7g servos
1x RC Receiver
1x Servo extension for the elevator servo
1x 3in Triblade Prop
1x 4s 650mah LiPo

In order to keep the weight down, all parts (besides wings, control surfaces and stabilizers, more on that later) should be printed with only 2 perimeters and 2 top and bottom layers. Use 5-10% infill.

For the wings, control surfaces, and stabilizers you're going to print them with just 1 perimeter and 0 top and bottom layers. I used 5% infill. After printing, you will cover these with a covering film, or you can use packing tape like I did. The control surfaces can just be taped onto their respective wings/stabilizers.

Depending on the tolerances of your printer, you may need to use a soldering iron to widen the holes for the vertical stabilizers, or use a file to remove material on the rear fuselage where the wing slides in.

Assembly:
You should attach the motor and esc to the rear fuselage before doing anything else. Then, attach the two wings together and cover them and the ailerons with tape or covering film. Slide the wing through the fuselage and fix it in place with CA or hot glue. Then attach the rear spars, again with hot glue or CA. Make sure these are perfectly square in all axis and are not warped from printing. Then cover the horizontal stabilizer, elevator, and vertical stabs with tape or covering film. Attach the horizontal stabilizer to the spars with CA or hot glue, again making sure it is square in all axis. Hot glue or CA the vertical stabs, again making sure they are square with the rest of the aircraft. Hot glue or CA the servos in place, as well as the front fuselage, and you are finished!

If you have any questions on the build process or the aircraft in general, please let me know. This aircraft is still very much a work in progress, and tends to be tail heavy even with 650mah batteries, so keep that in mind that it may need extra nose weight when flying it.
