How can you argue with logic like that? I hate it when I 'loose' lift.
My post had very little to do with the advantages/disadvantages of turning with rudder or ailerons. If you want to fly an incredibly large circle in the most inefficient way possible, go ahead, yaw away. My point was that Viking had said in numerous posts how poor the rudder response was when initiating a turn with the rudder. I pointed out that the Phoenix 2K has a completely flat wing, and the rudder isn 't going to do anything except yaw the plane along its longitudinal axis. It's certainly not going to initiate any turns. He listed 3 other planes that had much better response to 'initiating a turn' using only the rudder, and I pointed out that the 3 he listed all had polyhedral, which rolls the sailplane along its longitudinal axis (no ailerons needed) after application of rudder. Of course they're going to have better (faster) turn response with only the rudder.
I'm just trying to give the P2K a fair shake, as it's doing exactly what it was intended, its rudder does an excellent job.
Good day (and I mean that).
