3D Printing

Another take on the CF frame

In the last post I went through the process of designing and realizing my first Carbon Fiber-based H-quad. While the molding and lamination process itself was successful, the design was based on an open section, a fact that made it twist excessively even though it was quite resistant to bending. I thus went on to redesign the central "unibody" frame…

On the Road to a Full-CF Aircraft

The main driving force behind my current UAV experiments is lowering aircraft weight and noise. In principle though, this should not come at the expense of other factors, such as flying time, rigidity, responsiveness and crash-worthiness. So with these in mind, and after the eventual success of my last build, I've been planning for some time to build a quadcopter…

New ESCs, 3D Printed Raspberry Pi Mounts

The last incendiary event made me soon figure out that new ESCs would be required if I'd want to get the craft off the ground anytime soon. I went and grabbed a bunch of T-Motor Air 20A ESCs, whic turned out to be quite the reliable little beasts, and quiet too. Granted, the whole cable management business was a bit more…

CF-450: Designing the 3D Printed Brace

After the last experiment, I went on to design a frame that would have reduced weight but still be stiff enough. This time I planned to use the center plates of the F450 frame, because of their stiff connections to the arms. I started by looking at the weight breakdown of the F450 frame: Arms: 50 grams or 1.76 oz…

S01E01: The W-500

It always starts with an F-450, or a clone of it. Always. Unless you're a pro willing to cough up a five digit figure just to get in the air, or you're going for the RTF stuff, you must have come across an F-450 in your multicopter ventures. I think that DJI should be proud for this achievement alone though.…
