An intentional spin recovery at 700 feet AGL is reckless, and certainly not "normal" - do not participate in flights like that! A 152 Aerobat does not really "flat spin" it just spins. If something has been done to alter its spin characteristics, the aircraft is out of limits, so don't fly in it!
Spins are great practice, but like anything in a plane, they should be flown with caution, and respect!
