My Posts This: Topic  Forum		Furys are the Best out there!

My Fury Expert 60 with plastic tail box is the best heli I have every flown. I have never had a problem with there metal gears or the plastic case. I guess I don't do 3D enough....but you should have used the metal
tail box like they warn!

Better luck with your next heli.

My Posts This: Topic  Forum		how everybody doing with this

subject. I think MA should offer the cnc tail box at a big discount. I haven't had the trouble yet but I will not fly it now until an upgrade. Where is the best place to by the cnc tail box for the best price.

My Posts This: Topic  Forum		I hear your pain. I expereinced the same problem with my tail gears in my Fury expert. I was running a YS 61ST2 with a GY401/9253 on the tail and expereinced a tail gear failure after only 11 flights of hovering and basic stunts (no extreme 3D cause I can't do it yet).

I did report this to MA as to the cause of this problem and they asked me a couple of questions like what motor I was running and what Gyro. They did hint that I should run the metal gear box, which I have purchased, but still these things shouldn't where out after 11 flights. Certainly not a significant number of flights and certainly within the warranty period. Did not receive any offer for a discount or replacement on the parts that broke after the hard landing due to this failure.

I've been a loyal MA flyer for 6 years now but to be honest I'm not impressed by this problem. At first I thought maybe I didn't put the tail togther but after hearing other reports of this nature am led to believe that this problem is more serious and is a bigger issue.

I'll continue to fly my Fury cause I love it but this has certainly made me think twice about MA's handling of this situation.

My Posts This: Topic  Forum		Hi Guys,
Just could not resist jumping in and putting my 2cents in...
I have been flying for over 20 years...had just about every model ever out...and have been flying MA since the beginning....Yes Like everything in life they are not perfect..but they are very close to being the best flying Heli....What makes MA also great is that they evolved the model over the years...listening (although we may not believe quick enough) to the input of it's customers...
Forums Like RR are Fantastic and open up a whole new venue that was not available a few years back..and connects all our experiences and complaints worldwide....
My Point is since there are sooo many comments concerning the tail on MA helis..Then everyone Flood Tims Phone lines with comments/complaints until they listen and come up with an improvement....so be it I for one would not Mind paying a bit more for a better tail system...Hell I throw away $$ on Parts that just Look Good when I'm bored
Just my opinion...But I know there is a Very Large Following of Furys & Now Tempest...Imaging if Tim at MA received calls from Half the owners twice a week Until they fix the problem?

My Posts This: Topic  Forum		I too had a fury which I sold after a year because I couldn't be bothered with the tail gear issue. After looking at other Fury's, including my instructor's, I have come to the conclusion that it's was mainly my fault for the problems I was experiencing with them, but even he changes gears after so many flights (exact number I don't know).

Wayne Mann has suggested something that I suggested about a year ago on this forum. Helical gears may be less efficient but they mesh very well and you will have no problems with them. My old Hirobo Tsurugi (forgot how to spell) had helical gears. The Superio gears that Wayne is referring to is on the older models, all subsequent Superios were belt drive so finding these parts is even harder. The Freya EX WC is shaft drive and it uses helical gears in it's tail gearbox, only bad thing is that it won't fit into the XCell boom because it's larger in diameter (apart from being very expensive as well).

My Posts This: Topic  Forum		Helicul gears are not as strong as straight cut gears, the reason they are sometimes used is because they are quieter than straight cut gears. An example would be the gears in you car rear axle,they are helicul so they will be quiet. The reason the gears wayne mentioned are better for some another reason,like the strength of the steel they are made of, or they mesh better.

Yep, and tell that to the "fools" that are running helical gears in 5000+HP drag cars. I've stayed out of this until now....but please, gimme a break. If you are going to make a statement, at least make it intelligent.

The helicopter manufacturers would go absolutely broke
if they replaced everyones parts/helicopters due to failures.

That is ture.
But there getting rich on crashes with this
failure.
Why fix it, just sell repair parts.
MA should have a built tail unit in the kit.
This would put the tail gear box to a test.
Is the tail junk or is it a good?
But if you need a upgrade the tail is junk.
So lets play the upgrade game again.
Flame suit on, and I fly a FURY

Helical gears are used between parallel shafts. If the shafts are 90 degrees off, they are called "spiral bevel gears". Diff gears are usually hypoid. I wish all r/c helis used sprial bevels, but they are a lot more expensive.

As someone already pointed out, you are mistaken. Helical gears are stronger, handling higher loads and speed than straight-cut gears. They are quieter due to the smooth engagement from tooth to tooth, which is why they can handle higher loads. They aren't as efficient, cost a lot more, and produce an axial thrust component on the shaft that must be accounted for.

That is wrong.

And , rear axles are invariably bevel.

Please do read up before posting nonsense.

My Posts This: Topic  Forum		Tail Failure.

For MA to continue to sell a machine with a known problem is just plain wrong of them.

We're only giving MA this amount of slack because we are dealing with 'toys' here. You would never hear the same apologetic nonsense from the MA Reps above if we were dealing with an automobile here.

Imagine if Ford released a car with a known defect with the rear axle which will disintegrate is you reverse X amount of times. You'd scream 'SUE THEM' in an instant. At the very least , you'd expect a total RECALL.

As for MA's heli , imagine if tail failure caused injury to users/spectators ? What would be your view then ? Would you still whine , and say that you ought to have put in the metal tailbox ? I don't think so , you'd be looking for a good lawyer.

My suggestion to everyone who has had a MA tail failure is just to commence legal proceedings for product liability against Min Air. The way product liability laws are drafted in the US , Min Air is just waiting for a disaster to happen , in my honest opinion.

We ought to make MIN AIR responsible for this.

Cheers.

My Posts This: Topic  Forum		There is nothing wrong with the stock plastic tail box. It was intended for all of Miniature Aircraft birds up to the ones that are for the big bock motors. The plastic box can be used on the big blocks with great results also BUT, with todays gyros, motors and very aggressive flying styles it is recommended to use the metal units! That is why the metal boxes are supplied with the birds INTENDED for this type flying.

I myself am not an agressive enough flyer to mess up a set of gears in the plastic box so I have no problems with the plastic box. If it is properly set up, it will not fail, and there is no secret to doing the set up. The tail set up uses common sense and very little effort. Once you do it correctly, you can do it from now on with no problem. If anyone needs help on setting up the plastic tail box, please contact me and I will walk you through it! I will be happy to, that is what I am here for.

For the intended usage of hard 3D flight using the newest and greatest technology and the talent for very hard manuevers that it seems that the majority of pilots now possess, please use the metal boxed tails! No, it is not a gimmick to sell upgrade parts, it's just evolution!


Hope this helps!

My Posts This: Topic  Forum		i'll say there is nothing wrong with my stock plastic tailbox with gears over two years old and with a 601 gyro.
what is wrong is the pilot banging the tail left and right and having the the tail stop using the opposite control.

The plastic box is designed for 60 size heli's, simple enough... don't use it with an OS91

I was there when a factory rep set his Fury in.
Tail Failure flying with YS 61 and 401 gyro.
There is a problem with the tail if a rep can't
get is set up right.

My Posts This: Topic  Forum		I am not going to stop flying my Fury.
It flies like it is on rails.
But someone needs to make a tape on how to set up the tail and how to check the tail.
Not call me and I will talk you through it.
Post pic or a movie.
Myself I used gear marking paint to check the pattern on the gears when I build it.
This way you can see how the tail gears mesh.

My Posts This: Topic  Forum		Pistole

If you think that suing MA will help the situation, you are seriously in error. I talked with Tim at the recent IRCHA Jamboree and he told me they were the largest maker of helis and there yearly sales were around 5000 units a year. The average dealer price on a MA heli I would imagine to be about $600.00. It doesn't take a rocket scientist to calculate that the total heli sales are on the order of $3,000,000.00/year. The total sales will probably be about double that because of upgrade and spares sold, so figure $6,000,000.00 more or less. Total profit is something on the order of 10 -15% for most businesses, so one can reasonably assume a total profit of less than $1M. It won't take many lawsuits to eat that up. The lawyers for our clinic tell me that their preparations for a single lawsuit typically cost $10,000.00 before they ever get to court or any judgement is made.
The upshot of this rather long winded diatribe is that you can easily kill the industry. I would guess 50 lawsuits a year for a year or two, and Tim would decide to convert the whole operation to making toaster ovens or something similar. I wish they would make them stronger, too, but suing them won't get you there. Steve.
