Copter: LOITER_TURNS command with zero radius uses radius of last time LOITER_TURNS command was executed #19028
Description
During the testing of this wiki pull request ArduPilot/ardupilot_wiki#3769 I found that if Copter executes a LOITER_TURNS command (in Auto mode) with the "Radius" field (aka "Param3") set to 0 it will use the radius from the last time.
Do people think this is the proper behaviour? Another option would be to default to the CIRCLE_RADIUS parameter value.
