This shows the problem with the dead band issue with the Hitec Aurora 9 radio. In my case it's the left aileron but other owners have reported problems with the elevator and rudder.
*Update*
Hitec has a fix. You must send your radio in for a free update. They will change one of the main circuit boards which has a new D/A converter with more bandwidth to handle POTS that are badly out of alignment.
