While the proposed load may not exceed the effective moment ratings, it
seems like I remember a specific disclaimer that the T2X is not supposed to
handle anything larger than a 24' boom. As I recall, it's hidden somewhere
deep in the bowels of the manual. . . it's not widely published making it
one of those joyful things that you don't discover, despite your best
research efforts ahead of time, until you have the product on your doorstep.
. . and then find out that it's not suited to your needs.
There are many important aspects with regard to long term rotor performance.
. .effective moment is but one. Look carefully before you leap. If you're
serious about a rotor, I'd look at one of the Big Boys.
