"I use various FRSKY receivers with all my Pixhawks... all work perfectly including on 3.3 RC7

Note that the X8R sends telemetry back to the Taranis... In some cases if the X8R receiver is too close to the your GPS, you may get less satelites as the…"

"With RC5 I now get the error message "Error EKF POS VERT AGL" all the time.  The quad (550 H Frame) flies fine in loiter, position, stabilize.

"Looking forward to RC4  Best guess on when it will be available?"

"I noticed this with the Exuhf in my Taranis.  If channel 4 (rudder ... used for arming and disarming) is moved all the way right (more than 2ms) then mode on the HUD (and OSD) would change to RTL as the Pixhawk lost sync on the PPM stream.

"The timing of the rc pulse stream can experience problems if the pulse width exceeds 2ms.  This happens because the 2ms pulse hasnt ended before the next pulse starts.   This problem can occur in the ppm stream decoded in the pixhawk or in the rc…"

"There is nothing to address, the code is doing what it should.  Instead of adjusting the tx trim, you may consider setting the throttle travel (on the "servo's" page in the FrSky to a lower number, say 80% ) so that at center trim, the pulse widthis…"

"This is a long standing problem. Power cycle a few times usually solves it."

"Artem,
Do you have the parameter list for the SR0, SR1, SR2?  I can't find them documented anywhere... I guessed and set SR2 all the same as SR1, which makes the minimosd happy but have no idea what these parameters actually are...  appreciate any…"

"I regularly fly 3.1.1 on my flying wings... it works nicely.
The failure you describe could be related to a couple of things in your setup.
1) the level for the APM has to be calibrated (set it with a few degrees of up (positive incidence) and wings…"

"Toilet bowling is caused by a difference between the compass heading and the motion direction calculated from GPS motion.  
If you have toilet bowling, the compass reading is a problem.  If you change compasses, it is vital that you do a…"

"Try removing the data card and formatting it with your pc    put the card back in the pixhawk restart the pixhawk and see if it comes back to life.  I have managed to corrupt the card on a couple of occations and when this happens i get these…"

"Hmm that was the key to the issue above... yeah the CLI is there... and it shows 3.1.5.  (EKF introduced in 3.2)  Reflashed 3.2 RC11 and all is well...  

Brandon thank you."
