I heard from a friend of mine that the big Jet Ranger with the turbine at the 3D Masters was using metal blades for it's demo. He said metal blades are illegal to fly in the UK (same as here) and that it has caused a real controversy over there. The pilot was from Germany and you can do anything you want there, and either he didn't know or didn't seem to check and now the British Flying Model Assoc. is up in arms. Can anybody over there comment? Just curious is this was the case...

Maybe I'm wrong, but I don't think they're illegal, it's more of a BMFA issue.

When I meant illegal I didn't mean by the law..I meant according to what ever rules are in place. Like ithe AMA is for the US.

BMFA guidelines

BMFA state in the member handbook page 24 under

"A model helicopter must never, under any circumstances, be flown or run up"


(c) with metal rotor blades.

Not sure who job it was to check these things - looks like it slipped someone

I dont think they anyone has a much chance of proving it, even if they were metal

I Guess that it was written up before carbons were around, but saying that maybe they are more dangerous, it would depend on the metal and the form it took - obvousely i solid stainless leading edge would be rather dangerous whereas a thin aluminium skin less somewhat less so.
Anyone heard of any tests done on metal blades?
I think you can get them in italy

The problem with metal blades is if you crash, they don't break but just bend up and keep turning.

get your concepts straight

Nothing is illegal unless it says so on some statue or from jurisprudence (past court rulings).

The rules you are referring to are just derived from the clauses in the contract between the persons and/or clubs and the INSURANCE COMPANIES being it AMA or BMFA.

The blades are not illegal they just tell you that in case of an accident they (AMA or BMFA) will not cover the damages that's all.

You can fly your metal blades here in the US all you want but you will not be covered in case of an accident by the AMA. You will very likely be covered by your homeowner's policy though. And at the end of the day the AMA is only a "suplemental" policy, in other words it kicks in AFTER your homeowners policy coverage is depleted.

Don't confuse those facts.

Thanks for the free legal banter. I think we already covered the fact that I mis used the word illegal. We get the concept of the insurance thing that was not the intentions of the post. It was to discuss what happened at the 3D Masters with the big Jet Ranger and it's blades.

I would think Karl - Heinz Plich's 206 Jetranger would have had a private insurance policy to fly at the masters.

I know that here in the UK the BMFA derive alot of there guide lines from the CAA (civil avitaion authoirty) they published cap658 a guide to small model aircraft,

now it would seem that it is not illegal to fly with with metal blades, however all BMFA members is outright told that you must not do this .


in that the CAA deemed that it not safe to fly with metal blades so any insurances will not stand and loss of membership to the BMFA, LMA , now to fly a model that size LMA is a must (large model assoc.) so i expect while you would not prosecuted by the BMFA, the family of any injured would have a field day


my 2 cents worth

Kaz

p.s. only a MORON would ignore it

Thanks for the helpful information Augusto. It is always a pleasure to watch your flying, and I appreciate your information about insurance. Your video server is an excellent resource as well.

Thanks, John Cadwell

I would imagine a heli of that size and that blade loading would be safer with "full size" style blades made of metal...

but who knows

The thought of a metal blade on an RC Heli gives me the goose bumps the sight of one will make me run home.

My friend Remi from France gave me a set of "M-blades" a few years ago. They're hollow extruded aluminum. I never did fly them. Here's a picture...

I know that a carbon blade will give against the human body, and start to break up, which is a good thing trust me

I am not so sure about a metal blade, I think that if Rob Shaw was flying metals when he hit his arm, he would be armless now, that i believe.

I'm with Galifrey on this one, the heli is probably closer to being a full size ship than being a small rc model. It was huge and flew with the rotors going at only 650 rpm. I would rather it use the aluminium blades if they gave it better performance than degrading its performance by putting carbon blades on just for safety reasons. With a blade of that size they have loads of inertia and no matter what they were made of I don't think they would think twice about taking your arm off. Sure a wood blade may break off on contact, but the other blade will swing around and finish the job.
