RE: Telebee Gyro on the HBK2 ??
You're right, it would rotate the same amount and there would be less translational movement. I think the side to side motion would only affect the lower end gyros though, I can't see a gy611 getting confused over a little side to side motion, then again I don't have a gy611 on my hbk2 so point taken.
As to a blade strike on the gyro, what if you went into the ground at a high rate of speed inverted rotor head first? Think you could hit the gyro now?
