Climbs and descents take time to practice. Give students at least 1,000 feet to initiate and practice. Pay attention to rudder use, especially during the climb. Make sure right rudder is initiated at the same time as power is added, and make sure right rudder is maintained during the climb. Give them time to stabilize in the climb. For lookout, make gentle turns slightly left and right. Every time you lower the aircraft pitch attitude to lookout, you are destabilizing the climb.
The students should be comfortable in a stabilized normal climb before best rate and best angle of climbs are practiced.
Make sure correct rudder use is maintained in the descent as well. Gradually add in power off descents and descents with various flap settings. Spend time working on the point of zero movement. This tends to be a weak point on flight tests and is important to survive forced approaches.
Take your time teaching turns. Make the students are competent to perform gentle turns before going on to medium bank turns. I would wait until after spins before teaching steep turns. As with rolling into banked attitudes, teach them to look away from the turn and then into the turn before rolling into it. Always stress adding rudder into the direction of roll in and out of the turn.
