I shot this video of a helicopter exploding due to blade failure

Crazy seeing this in person

Best RC helicopter explosion ! (4 min 21 sec)

It's amazing the abuse these things take. He was flying the heck out of it for sure, but with these 3D heli's, that's pretty normal flying. Many times I think the failure is the result of all the flights before rather than that exact moment it came apart. Things get fatigued and weakened from a million bending cycles.

the blades he was using appear to be "no name" blades, and I've seen those break at the root in flight. i've never seen a name brand blade fail in flight. when you compare the roots side by side there is substantially more structure on the proven blades. On a 700 sized bird it's tempting to go cheap on blades during a rebuild as good blades are north of $130 a pair, but this is the result...

last weekend one of our club members was trying a no name hollow carbon prop on the DA 100. the rear of the prop delminated in flight making a horrendous noise, but he was able to land safely with the entire back of the blade missing.

One more reason I don't miss helis...

That's why parts on full scale heli's are replaced on a time basis. Obviously, the stakes are higher in anything that hauls people, but that same thought process might not be bad for the models also.

I know nothing about model heli's, just a thought.

I won't stand on the flight line during a 3D heli flight for that very reason. The equipment has it's limits.

Even since my 5 year old daughter was 2 inches way from being killed by a heli and I do mean 2 inches I just don't like seeing these things flying that close to ones head. Not hating just sharing info.

Yes, I've have to agree with you. While not specifically commenting on this video, I can't tell you how many times I've seen someone doing extreme maneuvers right in their face or close to others. I don't care what kinds of "mad skilz" you think you've got, stuff like this happens. Trusting your life or the safety of others others to equipment made for hobby use just doesn't make sense to me.

What a bunch of old geezer circle flyers. They have more skill than you can ever hope to have. Oh. wait. Damn. I though this was about hovering a plane over the runway.

that is the issue.... this incident had NOTHING to do with the pilot skill. Obviously he knew what he was doing as it pertains to 3D flight


It was an equipment failure... BUT... it DID happen during a high speed maneuver directly towards the pits and potential spectators....

Just no need for maneuvers like that.... with heli's or airplanes
