Boeing 737 Ceiling Flyer

cults3d

When strung up to the ceiling, the plane will soar through the air in perfect circles under its own power thanks to its propeller. If there's enough interest, I may release other aircraft models, including some actual prop-driven planes with twin engines. Like it if you want more. Watch it fly with a short propeller and slower speed: https://youtu.be/3tPDYEYpzAM Longer propellers and faster speeds are also available for bigger loops: https://youtu.be/QQKlanOFjk4 Materials: 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 don't need the rods if using the "Shaft and Prop", but I think they 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 and 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. Assembly: 1) Insert engine into 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) Use hot glue gun to secure electrical hardware in place on the lower fuselage. Be careful not to cover conducting parts that will contact batteries. 5) Pass red wire from motor up through fuselage, into nose cone, and out rectangular hole at top of nose. 6) Pass red wire from battery compartment into nose cone and out rectangular hole. 7) Solder red wires, 1 to each terminal on the switch. 8) Solder black wire at back of battery terminal to motor black terminal. 9) Insert 2 AA batteries, then screw on fuselage top. 10) Insert 2mm steel rod into coupler and push through hole in back of tail onto motor spindle. If using "Shaft and Prop", you won't need the steel rod. 11) Push propeller onto back of steel rod. 12) Hang from ceiling axis, flip switch, and take flight! Thanks to Navy876 for the cool model design.
