[TowerTalk] 8 pin rotor quick disconnects

[Jim White, K4OJ]

is this planned obsolesence (did I spell that right)

The weakest length when torque hits the mast is the one that will 
give...if you pin at the rotor I guess you had better hope the boom to 
mast connection slips under high winds otherwise you'll get a bucket of 
gears and bolts for a rotor!
