Sideslip correction and Servo yaw PIDs

Hi all,

Recently I've switched over from flying a Bixler to a Skywalker.

The skywalker param file available is entirely not suitable for my skywalker plane(think its because of the large differnce in servo throws). Tuning was a bitch.

Also, it is obvious that the skywalker is alot more prone to sideslip (its extremely windy in my country at this time of the year) than the Bixler. So my question is, does anyone know how Arduplane makes correction for sideslip?

The Servo Yaw PIDs are all zero in the skywalker param file available in diydrones.. does anyone know what the Yaw PID does? Roll and pitch are easily understood.. but im guessing yaw PIDs are for sideslip correction?

Or does Arduplane even corrects for sideslip by applying rudder deflections?

Many thanks!

Sideslip is corrected with the Rudder mix setting, mixing a percentage of the roll with the rudder servo. If the PIDs for yaw (rudder servo) are all 0, then you are effectively telling APM not to send any output at all to the rudder.
