"Maybe latest MP have changed something. I didn't update and fly my px4 for month maybe more(building skywalker 168 for long range) so I can't help you in this question."

"Do you mean internal PX4 power converter or BEC? USB alone is not enough, garanteed ;-) I see it on the PPM encoder. I use 3S lipo connected with balancing cable to PX4 together with USB to APM planner. In flight I use battery connected to Q Brain…"

"Ok, solved it... I synthesized the exact RC's signal with a standard arduino and fed it to the PX4IO board. The signal was also ignored. Than I changed some timings and found out the pulse needs to be about 480 Usec max.  My remote gives…"

"Yes I tried uploading with MP 1.2.62. It erases and seems to program because the green progress bar moves to the right. Just before the green progress bar touches the end, the PX4 resets, playing the OK tune. But than it is impossible to connect…"

"I understand.  I'm not asking about software tuning, but about such trivial things as protection case/normal pins/etc. Why APM boards are improving, but PX4 is not? 3DR not planning it as a head board for future development? "

"PX4 is cool and seems much more powerful, but I don't understand: what is the official 3DR roadmap for this boards? APM 2.5/2.6 now looks like the complete solution: it have the case, new compass at 2.6, etc. Improving 2.6 seems strange btw,…"
