"I have strong reasons to suspect that my PX4FMU has some weird manufacturing fault, it never worked as it should even with help from the designer of it and several other people. Sent off an email to inquire about what the RMA procedure would be, no…"

"Gary, yep I am aware of the disconnect/reconnect. Just for testing purposes I also tried to leave usb plugged in without doing anything for about 25min before attempting to connect, but still no hartbeat. What I did not try was resetting it, will…"

"tried both ArduCopter 2.9.1b as well as 3.0.0 rc1, firmware uploads fine but after that nothing, no hartbeat, so mavlink connecting is aborted...
Since I am not familiar with MissionPlanner at all I have no clue if it is behaving correctly, at any…"

"Tested now with the missionplanner download thingie, and I can apparently flash the firmware on the device but that's it. Mavlink fails to connect after 30sec of timeouts. So I tried it all from scratch again, same result after many attempts at…"

"Oh to answer your question, yep using PX4 without any IO now as the AR drone thingie is dead atleast seems to be. I still think the px4 firmware has an issue with versions on the motors as I cannot see anything hardware wise atleast on PX4IOAR that…"

"Gary, the LED's on the FMU show armed state with the LED's, forget exactly which LED did what (disassembled/disconnected at the moment). At least they do with the standard PX4 firmware ver I am running on it atm. 
What exactly do you mean by…"

"In case anyone is curious, this setup never actually flew and has since been disassembled and at least for the moment put on hold. If I get back to it and it actually flies one day I will update here with my experiences."

"this is a bit frustration inducing since I have been at it now since 2009, bought the original ardupilot etc, never flew because it never worked correctly, so I gave that up and waited a few years, now tried PX4 which has also never worked correctly…"

"hum, I think my PX4FMU is borked, I built a carrierboard for the microquad for it, everything checks out except it does nothing with the ESCS other than init them. It arms as it should etc, but throttle does absolutely nothing... So I ripped it off…"

"I will try the F330 PID's plus expo, I'll upload a pic tomorrow of what the setup looks like I seem to have misplaced the cable. 
Anyways made a PX4 adapterplate out of veroboard this evening, that uses standard KK2.0 spacing to attach to the quad,…"

"Awesome, I just knew there had to be a task out there for my high pitch sounding microquad <3!"

"The parrot setup doesnt have escs as such, it uses custom stuff that don't have a calibration, the issue is that px4 fails to detect and initialize one of the motors. All the motors run the same firmware etc latest version, so it's not that. The…"

"any more flight testing with this done? videos? 
I seem to be getting setback after setback, and will apparently have to abandon trying to get the px4 to work on my AR Drone frame. It does not initialize one of the motors, nor attempt to spin it up,…"

"Hmm, didn't even check for the modules existing also in 868mhz, cool stuff! I have the OrangeRx OpenLRS from hobbyking so I will probably try to swap the moduled for 868mhz ones :).
Do you have any estimate on how high the duty cycle is? what bps do…"
