The reason I have been flying in rate mode is because I started flying in rate mode back in 1990 or so with an Xcell 60 and have always preferred to maintain the rudder myself. However, with the introduction of rescue mode on the Spirit unit, I am now feeling the need to utilize heading hold mode to make the rescue setup easier. However, I would prefer to eventually have rescue + rate mode alongside heading hold mode setup and accessible when wanted/needed.
Most of my flying is low head speed stuff and scale but when I am doing aerobatics, I have always like maintaining the rudder myself: call me weird
For me, learning to fly the rudder in rate mode during any type of heli maneuver has become second nature so it really isn't much of an issue.
Cheers!
