Today at the park Iris took off happy, flew to my limit and came back like it should. I start flying again and Iris becomes unresponsive and heads for the ground, lands hard and takes off again, I was on loiter mode. I switched to standard mode to try to regain control. I was able to get it on the ground-upside down, but at least it didn't fly away again. Ruined one prop, but that's fine. I bring it home and connect to Mission Planner, did the accelerometer calibration just in case it got knocked off . Put new prop on and go to another place to try it out. Did good for a while and then started acting up again. When it went out to my limit at 150 ft away it just dropped, touched ground and took off again. I couldn't get it to come back to me, but I did hit the land switch and got it on the ground, but motors didn't want to stop After a minute they finally did. At the end of this ordeal my transmitter starts beeping-low battery for it. Could that have been my problem ? Low power on transmitter ? Should I reset everything back to factory settings and do all calibrations ? It seems like ever since I got to use Mission Planner been having intermittent problems.
Any ideas ?
