I train new students to think of flying a plane like driving a car. When your about to go up a hill in your car you don't floor it, you just roll on the throttle to maintain the same speed as needed. Most maneuvers, not all, are started from about half throttle and the power is rolled on to maintain that speed. Throttle is cut on the down line or wings tend to let go as you pull out. Some of the fastest planes I see out at the field are electric powered deltas, they can handle the stress better then a normal wing type of plane. I learned the hard way about too much speed in a big plane doing high G maneuvers.
