I am trying to use the v.setPitchYawRollXYZ command but it won#t work for me.

when using
http://127.0.0.1:8085/telemachus/datalink?a=v.setPitchYawRollXYZ[0.9,0,0,0,0,0]
nothing will change in the game. I get as response
{"a":0}
and the game receives Data.
Accessing Data from the game like altitude is no problem using the webApi.
Also the build in Web Interface works as expected
