A320LGW
A normal Spin will stop immedietly in the Yak52, given correct Load. ( Backseat Payload was appr. 85kg max in the ones i flew. Western Chute is 7kg, russian Chute is 14kg..)
Invertes and Inverted Flatspin stops fine
A Upright Flatspin will take some time to recover in almost every Aircraft. The 52 is there no exception, its a heavy Beast with small Controls.....
But: It Will Recover! You are waiting up to 3 turns waiting for a reaction..... If you try something different, you have to start from A....
