Some time ago I opened a post to understand why my Hexacopter shut down in the air, and crashed from 30m, resulting in considerable damage (2 engines, 4 arms, 1 gps, the landing gear and it's gymbal with servos, MinimOSD, etc). It was its first flight.
I love the community here, and the wonderful support you can get. Graham was kind enough to look at my logs and told me that it ran out of battery. Well, I thought, when I started the flight, the Mission Planner told me I had 52% of battery left, but it crashed after less than 2 minutes. Therefore, I guess it's the current sensor that plaid a trick on me, or I don't know what else to think.
So, the first hexa's frame being heavily destroyed, I bought a Quad frame, used the components that were still intact, and I happily assembled a second rotor.
Here's the video of it crashing. Yet again, on its first flight. As you can see around minute 2:08, it starts behaving erratically and at 2:32 it simply shuts down in the air. After the crash, you can hear the ESC and motors rebooting. Oh and -yes- this was a fresh fully-charged battery pack.
- balanced the props
- calibrated the ESCs
- calibrated the gyros and compass
- calibrated the PIDs using Dave C's method
- set the failsafe to RTL if current went under a certain level
It crashed while in Loiter mode.
I think I'm done. I'm either too unlucky for this hobby, or the Arducopter is a little too experimental for me to afford its costs (I've spent $3,000 on this, everything included), and I'm saddened about this. Too much effort and money for two flights on two different machines, both crashing on first flight.
Any pointers welcome?
