SetDesiredPitch of the AI aircrafts

[Roll Kate]

Hello eveyone,

Recently I'm working on a program controlling the AI aircrafts using the SetDesiredPitch() method provided by the PDK, however it seems that no effect is seen after calling the method. It's frustrating and unreasonable because other method like SetDesiredHeading() is just fine...I'm crazy about it... has anyone encountered the same problem? Any solutions?
