ground and flipped the flight mode switch to put the
quad into the magnetic heading mode. For the most
part, the heading was constant, but I noticed drift
that was possibly due to a trim adjustment.
As I was fiddling with the controller, the quad’s
port rear motor lost power and I came down on that
boom. The only real damage was a lost propeller
(Figure 29), but I have not figured out what caused
the glitch. I suspected a loose connection on the ESC,
so I tightened up those connectors and have flown
since with no issues.
The overall flying experience with the Quadrino is
very pleasant. It flies nicely, but suffers some from
the slightly complex setup and lack of auto control
range sensing (hence, all of the trimming). With an
improved firmware configuration and ground station
software, it would be an even better product.
I was excited to try GPS flight planning, but was
only able to get a GPS lock once, then the controller
never saw another satellite. I’m in the process of
troubleshooting why the GPS will not lock and will
then share my flight planning experiences with you.
I’m particularly excited about flight planning to
simplify data collection missions (like our IR mapping
project) and allow a more hands-off flying experience.
In the end, I thought the Quadrino was a really nice
product with a very small form factor. It’s lightweight and
has lots of versatility for the hacker/maker (Figure 30). I’d
really like to see more and updated documentation to make
the initial setup experience easier.
As I mentioned earlier, an automatic control range
determination like that of Open/LibrePilot would also ease
the setup experience.
If you are looking to really modify and customize your
quad, take a look at the Quadrino.
Until next month, fly safely. SV

Figure 30: Overall, the Quadrino is a nice flight controller with lots of
possibilities. It is designed for the hacker and experimenter that wants
to dig in and customize their copter with new sensors, code, and a lot
of knobs to adjust.
