Cardboard framed tricopter

Talk about reducing the costs of a build, this tricopter uses cardboard as a frame and has one less motor than its quadcopter relatives. There are almost no details other than those shared in the video after the break so we’re just going to guess based on what we see (feel free to share your own insight in the comments).

The smooth curves of this integrated landing pad makes us thing the frame was cut either with a CNC device or a utility-knife wielding ninja. Two of the three motor supports look just like what is shown above, but the third has a hinged mounting bracket attached to a servo motor. This way the propeller can be tilted around an axis running parallel to the support arm. We’d bet this feature is mainly for adjusting the yaw of the aircraft.

The video comments mention that this can hover when the throttle is at 45%, showing that there’s a lot lift available when needed. That is until you really weigh it down by adding plastic cages around the propellers. It’s kind of neat to see the thing ‘sticking’ to the ceiling at the end of that clip by driving the throttle wide open and using the cages as top-sided landing gear.
