In the mid 80’s friend of mine was messing around with Wally Sedgwick (50000hr WWII pilot, legendary Chicago DPE in the day). They went up to spin a C and got 2 spins and into a spiral. Burned 5000’ in the recovery. Wally said it scared him more than any event in his life including having people shoot at him. Neither of them have any idea how they got out of it.
Spins are an acrobatic maneuver. Spins can lead to spirals which kill you (if you release the back pressure it is going to go to a spin in just about anything I have flown that can spin). On a 150 with a good engine you can get it to spin (weak engine it is just going to stall and roll a bit) and there is a video of one of Bill Kershner’s CFI’s spinning one down from 18000’. Planes like a Mooney aren’t going to hold the spin, you lose control authority and at that point you are along for the ride hoping an air pocket or something knocks it out.
Vne and beyond comes very fast in a spiral and if you aren’t careful on the exit, off comes pieces (like the wing).
In short fun maneuver in gliders, 150’s, and the like. There is a reason though why some planes shouldn’t be spun.
Rolls in a Mooney are a totally different story but I wouldn’t know anything about that…..
