This should be a reminder to keep all helis at a safe distance as anything and unexpected things can and do happen.

I can understand a head came off cause the bolt but the head block broke in 2 no way thanks all any way for your inputs but this is my opinion about this model

Let's do some logic thinking.
The heli is about a year old since it came on the market.
It is being sold world wide, so we can assume that there are at least 200+ out there in usage.
There is 52 weeks in a year.
Assuming that average Joe bloke flies at least 2 flights every 2nd weekend that gives us 200 x 26 = 5200 flights.

Five thousand two hundred flights (and this would be a very conservative figure), we have one single failure that nobody knows yet why.
I am more then happy to take that.

To me they are excellent odds.
Let's see it in another way.
Over the years, I would have seen or been told or have read every single brand and every single model having crashed through a part failure.

On a recent large event here, another well known top of the line heli blew the Head apart. I own one of these and it's a big 90 by a company that has 20+ years in the business.
It was established that one of the blade holders let go.
The heli had a crash at some stage in it's life and I didn't see anybody running back straight to the company asking to have all their Blade holders replaced at no cost.
Nor did there go out a cry over the Net that this brand/model shouldn't be purchased due to serious flaws.

The only one that knows the type of life and the history of the model is the owner. Field Rep or not, if he thinks that there is an issue, then at the minimum, he is going to go back to the Manufacturer and discuss the incident with them and take appropriate actions IF required.

One thing we do know is that this Manufacturer is very, very quick to update the design or manufacturing if there appears to be a pattern of problems that Owners encounter.

This pattern has not been established by one single incident.
It's good to be reported, but let's not yell out that the sky is falling down

Alfred,

Well said, 1 out of 5200 aint bad at all..

Have put 170 ish flights on my x50, only had to replace all bearings so far, and still going strong.. Love it!!

Its easy to say there is a flaw, but no heli is perfect, but the x50 is getting pretty dam close with the new 8mm head, and the way that RJX listen to the people flying them, this heli will go from strength to strength, and will have a huge future..

Just my opinion...
cheers

WOW, I have been flying and watching helis for years and never seen any brand of machine do that, not saying they never have I just must be unlucky never being in the right place at the right time.

I read on RR the other day there was a guy who has seen just about every brand of heli break a mainshaft in flight yet I have never seen it once, what am I doing wrong? Where should one go for such exciting action?

Next time you fly please get some video rolling, I dont care what brand it is that flies apart I just want to see it, maybe if someone reading this has heaps of money they could weaken the J bolt and then go flying

look around the 4.50 mark.
This is my favorite (best/worst) crash ive ever seen. Not a mainshaft but nether the less a catastrophic, part failure.

Would have been nice if the camera man had zoomed in a bit, I don't thing plastic grips are the best choice if you fly like that.

This happened Tuesday 6/4/08, to a friend of mine on his Hirobo 50 while he was practicing his 3D maneuvers



Other than a new tail boon, landing gear, and of course what you see on the head it was not a bad crash

It happen to other brands

Clearly we are dealing with a bit or short-sightedness and narrow mindedness on the part of some people.

If we all had to write helis off our so-called lists because of things going wrong not one of us would be flying helis.

I am yet to hear of ANY heli that has not had any problems, from the Hirobos/JRs/Kyoshos/TT right down to the cheapest rubbish on the market.

If anyone that has been flying since 1982 hasn't seen this then I dunno - Must be flying in the back yard.

Some of us/you are flying the machine at headspeeds of over 2000 RPM. Take each blade at 140grams each and add the weight of the head itself and work out the forces at 2200 rpm, you have a serious piece of tragedy waiting to happen.

I guess I should write Hirobo off my list as well after seeing the above pics... OH damn - I would have to seel my Hirobos then

Opinions are like assholes - everyone has one and some of us are one!

The pictures of the Hirobo that rsalazar provided show a clear breakage of the Head block and not the mainshaft. Another pictures shows that there was no damage to the mainshaft.
Despite all this, I also would like to know, if this was a V1 or V2 headblock.

Does it really matter, you've already made up your mind that the Xtreme 50 isn't for you, that's OK, everyone has there opinion and there choice of what brand they want to fly, Alfred brought up a very good point in his earlier post, a very conservative number of say 5200 flights and one head block incident, which Mike is still looking to see what the cause was and he will work directly with RJX to figure it out. Why don't we just let Mike and RXJ work it out

Thats why i'm getting out of this hobby. R/C helis just cost to much for me. Thats why I sold my extreme a while ago witch I should have never bought in the first place. wasn't all that happy with it anyways.

All i've got left now are some airplanes and my T-Rex600E, YAY ME
