this could be a pop-corn thread... but it ain't... yet
Some very good comments on expo above, so I won't add any. Dual rate: I'm using a 3 position switch on my DS-24, for all the aircraft I own, including sailplanes. For all of 'em top position of the switch is Takeoff, mid is Flight, bottom Land. For the 3D stuff I use lo (usually 25-35% travel) deflections on the Takeoff and Land positions. Some of the 3D aircraft are quite pitch sensitive, and I end to over control for a landing, the more so if the whole gang is watching
Using reduced deflections for landings helps me regain my posture
