I think they SHOULD warrantee the mast. It's just like a similar situation. A buddy of mine is fighting with Ford as his new cobra motor with 4300 some miles on it grenaded. Ford says that he "drove it hard".... umm, or what the heck is it for then? Are you supposed to own an SVT (special vehicle team) car and drive it like someone in a crown vic?
Likewise, are you supposed to own a Racing cat and sail it like it was a sunfish? You buy something that is 2 years old and it fails...ok, perhaps it was worn out or went through to many stress cycles....you buy something that is 2 weeks old and it fails.... start asking questions....
The more I look into class rules, and stuff like dealers not taking care of customers, the more I just want to piece a taipan together and not even think about the non exsistant but make you feel warm and fuzzy warrantee
end of rant
