RE: Help with An OS.46SF-P
"Pattern" flying is aerobatic flying that conforms to the FAI-type pattern of maneuvers. They do absolutely NO type of flying that could be called "3D". Throttle movements are generally slow and smooth, and the goal of the flight is smoothness as you fly from maneuver to maneuver. The goal is to fly each maneuver with absolute precision and timing, with smooth flow between the maneuvers.
If your engine will idle well, transition well to full throttle, and then do the reverse, as well as run properly in the midrange, then it's operating as it's supposed to operate. It may not respond well to "bang, bang" throttle movement. IF you move the throttle smoothly and the engine responds, then it's correct.
The SuperTigre may be better, but still could be a bit rich in midrange with a slight stumble when you bang the throttle around.
