Un-spinable? You might want to watch this and look up the USAF report conducted on the spin characteristics of the ASK-21.

ASK21 is unspinable unless you equip with spin kit designed to move cg well aft of normal limits. Without this kit you cannot spin 21.

One addition:
The spin weights put the CG to the normal aft limit, but not beyond
it.
This is the same CG that you would have if a light pilot flies without
a copilot.

With the spin weights the ASK-21 is an excellent spin trainer.
