it makes sense why it would be a sudden failure coming into a hover after getting warmed up after a flight and finally letting loose at a high power/torque setting with lots of pedal needed. :/
i love the idea of a cogged belt for additional cooling/less stress on the belt around the pulleys, easier power transmission, however i think the real culprit is the bands weakening. i dont know what the original bands are EPDM, poly, or aramid?
my belts are getting replaced due to their age, i understand these are a 3 year item? i have new mitsuboshi red label main belts on the way for the same reason and i havnt ordered tail drive belts yet, so i am interested in what we can find!!
i just wonder if there is a kevlar reinforced/not wrapped, cogged belt out there.
I am following up with Optibelt here in Australia, will advice what I find out.
