to get rid of the weird sign changes for RC input we changed it to follow the
standard aerospace axis conventions. It was really annoying because control, navigation, etc. follows the conventions, but for historic reasons only the RC input did not.
This change is now in 4.0_beta, so it means that you will have to change your radio control xml file to get a positive value when pushing roll stick right and a positive value when pushing yaw stick right!
If you encounter any issues, please report them... and don't forget to do proper pre-flight checks (as you should always) before going into the air ;-)
