In the last two weeks, I had plenty of time to sit in front of Fusion 360 to design a few things, but no time to 3D print anything. As a result, I have a couple of almost ready projects. Yesterday I showed you 3D Printed Dualcopter Reloaded. Today I will show you 3D printed tricopter drone. Tomorrow? Who knows…
Last year I have designed and made a fully printable quadcopter frame called Isando. It was fun, but well… There are plenty quadcopter frames over there. Cheap and much stronger than anyone can print at home. But Tricopters? Good luck with that.
I've taken some of the parts of Isando Quadcopter frame, designed some more and here it is.
The most important part of any tricopter is, of course, the tail motor tilting mechanism. I had the following options:
- no bearings, just bushings
- single bearing and using the servo as a second support point
- two bearing and the servo is used only as a torque source, not support point
Guess which option I've chosen? Right… The tail will be quite heavy, so to somehow help with that, the rear motor has enough space to use 5-inch or 6-inch propeller. And the rest? The rest is quite standard:
- Standard FPV camera in the front
- 30.5mm hole spacing flight controller in a middle
- video transmitter and radio receiver just behind the flight controller
- ESCs on arms
- 5-inch props in front
- 5 or 6-inch props in the back
Of course, I will share STL files but only after I will print and assemble this thing. So please wait a little longer.
