I've been trying to figure this one out and not having much luck. When I map a mission with a turn greater than 90*, I seem to get this weird twitch (see video). You can hear something odd in the motor speeds as well at the turn. The video shows the same turn in two consecutive passes/loops. Any ideas? http://youtu.be/JiJiu4DtaH4 The leg was on a 64* heading turning to a 183* heading at a programmed speed of 10 m/s. I used this same turn several different places with the same results.
