Aircraft to spin: C152 Aerobat for its forgiving nature. Not to spin: PA38 for its tightness and associated recovery problems, and the DA20 Katana, which wants to remain spinning for some time after the recovery process is implemented. Inadvertant spins, as mentioned, are easily prevented, providing the wings are kept level using RUDDER ONLY. As an instructor I have been spun unintentionally twice, and due to the spin practice during my own training, I was able to recover without second thought. Give it a go, youll enjoy it too.
