Hi. I am having trouble during auto takeoff using catapult launch. After I changed the mode to auto, the motor started to spin. I waited for a few seconds and then launched the plane. It shoot to the sky for only a few second and then suddenly it roll to the left and drop.
I had successful repeatable manual takeoff before this. I am using Arduplane v.3.8.4 and skywalker 2015 airframe.
Here are my parameters for catapult launching auto takeoff:
TKOFF_THR_MINACC = 0
TKOFF_THR_DELAY = 0
Here is my datflash log: https://drive.google.com/open?id=1hasxorhzDJ9-4vaLyaenTaC-DASZQGlK
I am hoping that who has experienced in using catapult launch / great in log analysis can guide me.
