I'm just thinking that if someone took the placard method... which is cheap and expedient and perfectly legal.... there is still nothing on the tail to prevent the rudder from jamming. Aside from a warning not to do intentional spins.
If being placarded is the minimum, I won't not purchase the plane. But, what other "minimums" have occurred? Or, less than "minimum".
I'm thinking - if the rudder stop is dangerous during intentional spins, then its just as dangerous on unintentional spins. And if the spin is unintentional, then you've already got one problem - don't need two.
To me the placard is a temporary fit, until the cash shows up on the tree. 500 bucks is 500, but the risk I might take shouldn't be shared with my passenger.
