I never had any report of 'erratic' flying characteristics of a chacon, but certainly they sometimes developed a spin (as per the thread subject) without any instability.
Smooth and balanced flying is always the key: I've even done a GCA with a load which flew (as much as we could tell in IMC, according to the crewman watching out of the door) without any problem.
