Align is giving this away to those who exploded their tail rotors before getting the new screws. If not, you didn't whinge enough.

We know that, Its just for a picture of the screws.... I have also noticed that all the new tail rotors are shipping with the new screws in the package.... so you can change them out when you purcahse it.... I dunno when those are gonna hit the states.....

But Honey, I can't live with just stock.....

Is it black or silver?

The black kits have the corrected bolts it seems.

You should be taking the pieces back apart anyway to re loctite them, so just check the color when you have it apart.... like was said... the black ones without the shoulder are the new ones.. the silver ones with a shoulder are the old ones...

Look at it. The replacement bolts they sent out were wrong also.

Boyd.... you may think the replacements are wrong, but they are what they are... there is no right replacement out there that align will send... as far as they are concerned the black ones are the right replacement... and FWIW, they work great for me....

There is a valid reason for the shouldered area on the bolts as shown on the Align engineering drawings. The bolts provided are not shouldered and are the wrong length. If you're happy with the fix for your $520.00+ heli then good for you. Sorry, but I just want it right.

its funny how this thread has 6500 views.... for some screws...

So the new screws arn't right? Is it really that hard for align to send the right ones? I mean come on you dont need to be an engineer to pick the right screws for the job. I haven't been keeping up with this thread but I have replaced different screws on my XL because the align ones were junk.

So align messed up again? lol!! Someone please send some pics of the new screws so i can see for my self

Ok, first they are the right length, as far as I know, because they aren't too long to thread into the tail shaft hole, and they aren't too short because they thread down quite a ways, definitely adequate.... ...
Second... The shouldered area on the screw is what caused the problem in the first place... stopping a tap half way up a shaft creates a weak point right at that spot, and that is why the screws failed... adding a shouldered area to the the steel screws would weaken them in the middle and they might fail as well. Fully threaded screws aren't the worst thing in the world... they just aren't as smooth, which isn't a problem, because the double bearings in the grips compensate for it. As for their width, I read you saying they had side play, but for the life of me, I cannot get any side play once they are bolted down.... I don't see what the problem is here....

Tmaster, its the same screws as in the picture here.. the ones on the bottom right...

Although, the ones in the pic do look short, but my replacements side by side look exactly right....

Align sent me the entire HS1147 repair kit, not just the screws. Just the screws are useless if the rotor has already exploded.

Ovaltine... did the screws seem short to you??

Based on this fine piece of attempted mechanical engineering, I guess we better throw all the fully threaded fasteners away, as the heads are going to break off now that they are at the theoretical weak point. ???????????????

You crack me up Ozydego

Too much of that Buckeye cold weather maybe.

first of all they use a die to make threads

or a special cutting tool on a machine.

second of all how are they screws breaking, it seems real funny that they would break off unless you were in a really bad crash, or had a defect.

Third of all I dont see any problem with those screws unless they are made from a cheap pot metal. Use some good screws made from steel, or even 316 or 18-8 Stainless steel. You wont ever snap one of those unless there is a defect.

done and done!

Top 3 are from crashes, last 1 i just took some pliers to it lol!!

I just go on what I know... Where the threads stop, on both sides of the screw there is a point where the concave of the thread stops and it is the first spot to flex when screwed tight into the hub. With the screws being brittle I guess, that is where they broke, right at the point where they come out of the hub. A fully threaded screw has the same strength throughout the length and will break if brittle at it weakest spot, which can be anywhere along the shaft, and a lot of times it is at the head. I'm guessing that the steel screws aren't nearly as brittle and bend rather than break...
