lol..no doubt the skyhawk is one docile bird. whenever i'm required to teach spin entry/recovery techniques to new cfi students, i have to carry at least 2,000 rpm's of power or put a case or two of oil in the baggage compartment..then of course if you don't apply anti-spin controls, they simply quit rotating after a couple of turns, you recover from the dive after full forward elevator to break stall.
what about this grumman yankee? i'm not familiar..only seen the tiger and cheetah. does it have a fast roll rate? large ailerons? something unique about the wng? the control surfaces? on take-off, does it exhibit a greater left-turning tendency, needing more right rudder or just a pig for available climb rate with a magnetic affinity for trees?
