"Hi Martin, maybe all Pixhawk owners who experienced IMU problems should also supply info on date of purchase of their Pixhawk. Maybe then, we can see if this problem is related to a particular batch of Pixhawk."
"Ok thanks. I'll replace ESC 4 and try again."
"Andre, please see my attached graph in reply to Tim's post. Why does all current and voltage readings cut out just before the spike in signal to ESC 4?"
"Please have a look at the attached graph. I have plotted RCOut together with Voltage, Current and Vcc. Notice that all voltages and current and Vcc already stopped recording just *before* the moment RCOut Channel 4 spiked. So, that could mean no…"
"Andre, what if the power module is faulty? Somehow it prevented enough power from reaching the ESC but just enough for the Pixhawk to record it's final death plunge. Just a speculating."
"Hi Kabir, see below. Thanks."
"Thanks Tearig.
Quad is a 250 size H-frame mini quad.
Motor: Tiger Motor MN2204 2300kV (brand new)
Props: Gemfan 5030
ESC: Afro 12A pre-flashed with the latest SimonK firmware
Batt: 2x Turnigy nano-tech 1300 mAh connected in parallel

"Andre, that puzzles me too. Your reasoning sounds plausible. The voltage shouldn't go that low as my batt still has more than 60% charge left after the crash and the no-load voltage of my 3s batt is more than 11.3V."
"Thanks Tim for the analysis. I thought the current graph showed that the voltage and current reading got cut off abruptly in mid flight while the other data is still being recorded. Just like what Andre was pondering (see below), if in fact a…"
"This is scary, Graham. I am also using Tiger motors, and all original 3DR components. But I am not even doing any flying, just hovering on the spot, and yet this happens. Sad. My faith is shaken now."
I was maidening a mini H-quad with a Pixhawk running AC3.1. On my first hover in stabilize mode, it worked beautifully. It was hovering perfectly still without any trimming needed. About 4 minutes into the hover, with the quad at about 2 meters…
"Thanks for your reply, Matt :) Yes, I think it is a good idea to set up such a repository so that everyone can dump their quad set-ups together with their PIDs into it. It will certainly help newbies, like me. Is the AutoTune good enough for small…"
Hi all,I am totally new to APM or Pixhawk and am building a new quad from scratch. I am not sure if there is such a thing as a PID library available, but can anyone point me to a PID library or repository featuring PIDs for different quads and…
"Hi David,
This will work. In fact, the Predator V2 and Attitude V2 comes with it. Just connect the balance tab of the main flight battery to this filter and you are good to go. There are connectors on it for 2s, 3s and 4s, so connect to the…"
