When strung up to the ceiling, the plane will "fly" in circles under the power of its propeller. If there's enough interest I may release other aircraft including some actual prop-jobs, maybe even twin-engine. Like it if you want more.
Watch it fly with short propeller, slower: https://youtu.be/3tPDYEYpzAM
Long propeller, faster / bigger loops: https://youtu.be/QQKlanOFjk4
1) Motor + switch + battery case ($12 for a set of 5 each): http://a.co/elPTgfI
2) Steel rod ($7.87 for a set of 20), 50mm length: http://a.co/7UfjWzZ
[You do not need the rods if using the "Shaft and Prop", but I think the rods work better.]
3) M3 screws, 5-10mm x 2
4) Two AA batteries
5) Soldering iron, flux, solder
6) Transparent filament to suspend plane, ~100cm
7) Screws to mount axis to ceiling
8) Glue, either E6000 or cyanoacrylate.
9) Hot glue gun
A note on printing: The body + wings part should be printed upside-down and rotated 45 degrees to fit on a 20x20cm build plate. This model cannot be printed on a smaller build plate if you intend to install the motor and batteries.
1) Insert engine in tail with wires facing up, then glue tail to lower fuselage.
2) Glue nose cone to lower fuselage.
3) Remove electrical hardware from battery compartments (spring and gromet) with wires intact. I found nippers to do this easily.
4) Hot glue gun the electrical hardware in place on the lower fuselage. Be careful not to cover the conducting parts that will contact the batteries.
5) Pass the red wire from the motor up through the fuselage, into the nose cone, and out the rectangular hole in the top of the nose.
6) Pass the red wire from the battery compartment into the nose cone and out the rectangular hole.
7) Solder the red wires, 1 to each terminal on the switch.
8) Solder the black wire at the back of the battery terminal to the motor black terminal.
9) Insert 2 AA batteries, then screw on the fuselage top.
10) Insert the 2mm steel rod into the coupler and push though hole in back of tail, onto the motor spindle. If using the "Shaft and Prop", you won't need the steel rod.
11) Push the propeller onto the back of the steel rod.
12) Hang from the ceiling axis, flip the switch, and go fly!
Thanks to Navy876 for the cool model.
If using the "uniprop", I recommend printing it on its side, with supports.
