My IRIS tips over to the starboard on lift off. The right side props touch the ground before it is airborne. Full left on the right hand stick makes only a slight difference.
Prior to my attempt to switch to a 9xr transmitter it behaved great.
As part of trying to get the new TX setup I reloaded the parameters, a mistake I think. I did this because it would not arm, it appears that was because the 9xr ppm throttle output was too high, I lowered that with TX trim. It now arms but tips over.
I have tried recalibrating the ESCs but that had no effect.
I would like to re flash the pixhawk and return it to factory settings. How can I do this?
I think I have it sorted out…
I updated the firmware, loaded the IRIS parameters and then calibrated the accelerometer, compass and ESC.
It seems to be running well except… The “elevator” (right stick forward/aft) was reversed, it’s was in altitude hold mode, it’s nice to be able to let go and think a oh what is happening. I reversed the channel on the TX and functions normally now.
I had a HDOP fault but that cleared up after 15mins.
However I have a fail safe kicking in. It’s happened about a minute into all three flights after I sorted out the pitch.
I need to learn some more on this issue… There must be a way to pull RSSI values off the logs and way to set the failsafe sensitivity.
Does anyone have a link or advice on setting up failsafe? I am very happy I set the failsafe to land instead of RTL, I was in a confined and treed area, the climb to 20 meters would have been a catastrophe.
