is a scale chart that shows the best scaling setting's for a particular plane like the p-51d--for quicker turning-rolling nose up--nose down--i use the "k" button to get the nose up a little faster---and the flaps for tighter turning...i notice sometimes when i pass and ene plane it's like he's on my 6 almost immediately.and when i'm in a dual and i pull back on the stick-it's slow to climb--i use the regular x-52 throttle and stick.
