"Hello,I am using PX4Flow and Lidar with Pixhawk and I am getting an error “EKF2 IMU0 has stopped aiding” on MP. in addition, the altitude is changing a little even I put the UAV on a table with a stable condition. I was wondering if the calculation…"
"Hi Clifton,
We will try to modify the mix file and have a flight test. Clifton Hipsher said:
The side arms are too long. This non-standard configuration confuses the firmware and I'd wager this could be the source of the high vibration levels."

"Hi Clifton,
Thank you for your help.
As you mentioned, the vibration level is extremely high, I noticed that if the vibe.clip was rising, the drone will suddenly climb up and lose altitude control.
I tried to decrease the weight of IMU measurement,…"

We use copter 3.5.5 for our hexa-rotors UAV.The Vibration is in good level in stabilize mode. but changed worse in Loiter mode with forward flight.The altitude control is getting worse.Can anyone help?the bin file is as…
Recently, I've added RTK GPS module on my PIXHAWK(firmware 3.3.3).I checked the Ublox's GPS protocal was NEMA 0183 which inluded GPGGA GPGSA GPGSV GPRMC GPVTG GPGLL.But my RTK GPS module can give BESTVELA.So I wonder if PIXHAWK can receive the GPS…
"Hi Randy Thank you for your reply."
"Hi Randy
I've just fly my Quad-rotor with 3.4RC1.
It will descent slowly, almost crash in AUTO mode.
I don't think the LIDAR is used in AUTO mode.
Any ideas? Thanks!
here is the tlog in the attach files.2016-06-16 12-18-53.rar"

"You said it!
I've downloaded the MP_1.3.38, and now I can change the PID parameters.
Thanks!
Awesome! You guys have done a great job! "

"Randy
in Copter-3.4RC1, i can't change the PID parameters. why?"
in Copter-3.4RC1, i can't change the PID parameters. why?"
"And what's the relationship between EK2 and EKF?"
"Randy，
My octa is now running 3.4RC1, in the parameters. should I need to change EK2_ALT_SOURCE to 1 in order to let pixhawk use LIDAR ?
and the default value of EKF_ENABLE is 0, should I need to change it to 1?
There isn't any parameter…"

"Thank you very much, Randy.
I will try Copter-3.4.
Then I'll share the results.
Thanks."

Hi everyone.I recently assembled a new octo-copter(running 3.3.3) with a LIDAR.In loiter mode, it can hold the height good.But in auto mode(the Dalt is 8m), it will drop slowly, the LIDAR's result is almost 2m. I wonder the pixhawk does not use the…
"i haven't my buzzer mounted."
"thanks！Justin.
i use futaba T8FG，when I fly the hexa-copter with 3.2.1, it is all right with the flight modes changing.
i will try changing flight modes with the telemetry later to see what happen.
you said it！ i will try to reset the copter to…"
