Finally got to handle the 172 like many have wanted to in the past a few days ago....
Only got into the incipient phase in the video, sorry...

Unfortunately, just full back pressure and left/right rudder... We do the spins in our training with neutral aileron... The instructor eventually demonstrated a few fully developed spin and I think he was cross controlled... I was surprised how difficult it was to get a 172 into a spin (and ultimately a fully developed spin) in the utility category. We needed power (about 2000 rpm) each time to get the bird to aggressively turn over. Im sure that when your more aft, its a bit more serious.... Regardless, its a great experience to stare that dirt in the face and pull out!!! My instructor made a great point in doing spins that not only do you have to exit the spin, but also exit the spin without overstraining the airframe.... We sometimes exited the incipient phase with a >90° pitch change to re-enter stable flight... First time I felt some "Soft G's".... Heres a pic of our g-meter.

Looks like fun! My 1 time thus far spinning a plane was in a 172S. "OK now break the spin. I said break the spin. Crap we're wrapped around tight hold on!". Lost 3,000+ feet. I guess the CFI was a little aggressive? Spun a lot fast than this one too, though people say the 172 has a docile spin.

More like 1 roll then the spin. Too early on the rudder you think? Try to avoid the accelerated stall whip, it's hard on the tail when you snap the rudder over and could cause the tail to snap off if your airspeed is too high. You don't want to snap roll this thing, its a 172.
carefull out there.

Eh, in my experience.. that's just what 172's do. I've never gotten a 172 to enter an actual spin without being pretty aggressive about the rudder/pitch combination. Basically.... wait for the stall horn, then pull, then rudder. And hold. Almost always you'll get the roll the first time, then it devolves into the spin. Without doing that, they have a tendency to just do a spiral dive.
Basically... spinning a 172 kinda sucks, because the attitude is so nose-low, and the entry is usually pretty weird. And then if you actually get it into a good spin, the recovery takes a bit of effort and isn't as simple as just adding anti-spin inputs. I first did spins in a Super Decathlon, then followed that up with a 172. The Decathlon spins beautifully. The 172 is a bit of a mess in comparison.

Who am I? Where are my pants?
I think the problem is that so many GA pilots haven't *really* spun an airplane, so they don't know what it actually looks like.
I haven't spun a Super D, but its little brother, the Citabria, is wonderful at it, too

That's not the D's little brother... That's the D's Grampa!

What does it actually really look like? My instructor showed me one time last week but that was on paper and all...I remember something about the wing on one side is stalled and the other one is not at all. That's right, eh? I don't frick'n know. Doesn't the wing root stall faster?

by taking the brain out of the pilot and cutting off the main gear in flight with special pyrotacticts. ;-)
oh, so dangerous, you guys are just so dangerous.

Why are you pulling almost 3.5 g's?

I'm not judging here do what you will do but here take this and do something with it please...this is no stick measuring here.
This is taken out of the book word for word Basic Aerobatics Geza Szurovy/Mike Goulian (p.144)
Snap Rolls
The snap roll is an autorotational maneuver. it can be thought of as a spin along direction of flight in which the aircraft was traveling prior to beginning the maneuver. This is made possible by such a brisk rate of change in pitch and yaw that the direction of the relative wind is unable to keep pace and remains unchanged. The abrupt control movements imply a high acceleration rate (Gs); therefore, entry speed control is critical and the maneuver must be performed well below maneuvering speed to allow for a good safety margin. the snap roll as performed by establishing the proper entry speed and briskly applying full rudder in the desired direction of rotation followed in a fraction of a second by aft stick to create an accelerated stall. These control movements are not separated but "joined" with a split second delay in stick application....The snap roll uses up a considerable amount of energy as can be seen from the high G meter reading and the big drop in airspeed by the end of the maneuver...Because the snap roll is started at a low airspeed to begin with, the snap roll can get the pilot into trouble if mishandled, most commonly resulting in an inadvertent normal spin.
What you have here is a video of a 172 snap roll then a spin or two performed in sequence. Tell others you're doing a snap roll to spins in a 172. Well, almost a proper snap roll, just work on rudder first in joined with aft elevator. Good job, keep up the practice!
