Hey Guys,

Always stand to one side or the other of your machine when hovering. I was flying my GMP Cricket today. I put a set of used tail blades on the machine. They were covered end to end with shrink tube blade covering. All was going well then all of a sudden, it sounded like a fire cracker going off. One of the tail blades flew off-literally pulled right through the wood ! By the time the machine came to rest on the grass, the vibration caused by the one blade now missing caused the other blade, tail grip and all, to launch off somewhere too. I still haven't found it. However, I did see the first one whizz right by my head. Had I been directly behind the machine, it probably would have hit me in the face. No more used blades for me ! Stay safe fellows.

Why on earth would you fly a set of blades like that?

To hover is divine, the alternative is rather PLANE.

What, nobody ever uses used blades ? They looked fine and I'd used them before. I had a brand new set of NHP carbon fiber blades come apart on me once. It happens.

Used to make my own tail blades out of wood back in the early 1990's. Had great luck with it. Shrink wrap just makes a wood blade more efficient. Great advice on standing in line with the tail blades.

I think he meant, why would you use tail blades covered in shrink wrap? I've been involved with helis since the mid 1990's and I've never seen such a setup.

I seem to remember way back in my Raptor days, that the Marrvik wood blades came with shrink wrap on them from the factory.

Good reminder, thanks. A tail can also kick up a small piece of debris, never be in line with the tail blades when the heli is on the ground.

When I started in 2008, there were cheap 325 mains made from wood and shrink wrapped.

My point is/was why fly a set of used blades with shrink wrap when you can buy a relatively inexpensive set of new carbon blades.

No matter how new or good the blades are I always try to take off with the tail blade rotation out of my eyeball path.

Unfortunately, you can't buy carbon blades for a Cricket.
