Hi Folks

On a 5 bladed 600 size rotor head, what is the range of end play at the blade tip...

When you grasp the blade tip gently, how much vertical movement?

I am interested in the range folks have on their existing helis...

Thanks

what head have you got?
while different brands will have different tollerances in the machine work, there should be minimum play if any at all. this is something i have never actually measured(or given much thought to for that matter), its just that if there is excessive play anywhere, its a no go. with the blades off, you shouldnt be able to feel any up and down play. with the blades in place i imagine you will get slight as the blades may shift in the grips because of the leverage.

drive a rotary, fly a rotorcraft
