I've been messin with profiles since the inception of the Morris offerings and had several discussions with Walter himself back in the day. Have three of them presently as well as a 33% Edge and a 40% 3W 330S. My current dilemma is the 3W 150 in the 330. It has ample power and flies great. I'm trying to get the throttle curve for hovering and am getting frustrated! I have a 10X and am trying to tailor the curve. Maybe it's the engine? Are you 3D and hovering gurus of large aircraft moving the throttle stick one or two clicks, or zero to half travel to get the engine to do what you want? It seems that one setting is too low and the next click of the stick is too high to keep a steady hover, or to start a torque roll? I've watched others and it seem that they move the throttle stick quite a bit. My style is to move it a little with just the right rpm setting between clicks. My engine is sthe older style 3W 150. I've witnessed the new style 3W engines in action at the Chatanooga 3D fly in and it seems like they are crisper and a bit more responsive in the throttle. Help me out here_bob
