I actually read this thread, put the tail together then decided to put the Fury Tail Hub on, works a treat!

I think my solution to this problem is good. The problem is the set (grub) screw. It is hollow where the nut is secured and therefore not as strong in that area as the remainder of the screw.

Taper the ends of two 20mm socket head screws so that they will fit into the indentations in the shaft. Install the hub using blue or what I use, green #290 Loctite. With your Dremel remove the socket caps and using Loctite install the nuts. After you install the nuts grind off the excess screw material. The down side is that if you want to remove your hub you will have to use locking plyers to remove the screw. It is easily done and 25mm screws are reasonably inexpensive. I've built two SEs with this modification and have done this to my converted 90 with good results. If you really love smooth running machinery you can get the tail rotor balance almost perfect by selectively grinding different amounts of screw material from each side.

se
how about my second option,
to use a grup screw to hold to the shaft and then scure the bearings with cap screw, i will use green loctite.

or i just do as DTM said not to over tighten the nut and apply some green locktight.

i checked other heli manufaturer i think it was hirobo and they are using cap screw ro the tial assimbly.

your answer are really apreciated

woman will never understand. The field is where you prove it not by your tong.

My SE kit came with the pointed tip set screws. They were assembled with blue lock tite. On the first time I brought the head up to speed as I was checking my throttle curve. Bam! one tail grip let loose!

I had read about the grub screw problem, so I was aware of it. I think the issue is more of how tight you make the nyloc nut on the grub screw when assembling the tail hub! My pointy grub screw broke flush with the hub.

Upon rebuild, I was very careful to triple check everything! The round nose grub screw supplied with the new tail hub seems to be working fine. I have over a gallon of fuel through the heli now with no further problems.

Fly it like you stole it!

My Raptots have the min. fury tail assembly
All Raptor 60 and 90 tail assemblies are garbage - no thrust bearings. I know alot of you will disagree, but I don't believe that a heli tail should be without thrust bearings and a more rigid tail.

I never installed the thunder tiger equiped tail and from building the kits from start, always installed a miniture frury tail assembly complete with hub, blade holders, thrust bearings, radials, etc..

Oh, forgot - Yes I did first fly the raptor tail and same thing happened, blade and holder flew off in 2nd week of flying. Same thing happened to other Raptor owners at my field.

i totally eliminated the 18mm set screw and went with a 3mm grub to lock the hub to the shaft. i used a 3mm socket head bolt with a shim washer to secure the blade holder bearings. works great so far.

same problem appear here with rap50,v1 and 2 .I see that many version ov v2 report a warning advise in the building box with the new screw.They say that are much stronger than the old.

DANGER Raptor 90SE Tail Failure
Hi All,

I really don't know where to start on this one.....Since Christmas I have been building my new Raptor 90SE. Good news one would have thought. I did at first as I already have a Raptor30v1 and a Raptor 50v2, so I went the whole hog and bought the 90SE and the MD500 fuss kit to fit at a later date.

Equipped with an OS 91 C Spec pumped, Youngblood Muscle pipe, NHP Razor 710 Blades, CSM RevLock, CSM Micro SL560 Gyro and 4 Hitec 5945 servo’s and 1 Hitec 5925 servo for the tail the “standard” helicopter is at last finished (without the fuss kit).

I have to say at this point I’m pretty feed up with the thing as I seemed to have run into problems that just should not happen. As far as I’m concerned the quality control at TT, Youngblood and NHP has left the building along with my future custom.

In no particular order here are some of the things that I encountered.

• Top and bottom main shaft bearing blocks threads required re-tapping as anodising and crap had filled them up. (Part No & BK0488 BK0489)

• Socket Screw on Carbon Pitch Frame fails on Elevator Control Lever.

• Carbon Collective Pitch Side frames (BK0464) were made from 2 different thicknesses of carbon sheet. One frame measures 2.24mm the other 1.9mm thick. Great quality control TT. By the way does any know which ones right?

• Bolts that were supplied with Muscle pipe were wrong size for the OS, two required reducing in length two needed to be longer. Not very good for £90!!!!

• First set of NHP blades were damage during manufacture but got to the shelf for someone to buy. Damage in the coating around the blade tips. Again, not good for £70!!!

• Instructions fail to state where the Washout Base Guidance Ring should be secured. (Phasing)

• Carbon base plate required considerable modifying to clear OS head making the front carbon spar weaker.

• And 2 socket screws in the bags had no thread.

That will do for now anyway………..

So this lunch time I decided I could not put it off any longer I would start the engine and run a tank of Coolpower 12.5% fuel through.

So in the garage the engine started 2 time of asking, things are looking up.

Then I carry it out to the court yard where I often run up my models. (I never hover them here as it’s too confined).

The plan was to bring up the head speed to ensure things were ok before making the trip to the flying site.

About 2 minutes for revving up to about 1K head speed the tail blew apart.

Upon investigation I found that one of the Set Screws (HME3-18B) that retains the Tail Rota Hub (BK0307) to the Tail Shaft (BK0374) had snapped.

At this stage I must say I’m totally new to RunRyder but hang on didn’t I see the same thing had happened on there to someone?

Low and behold olivierparis posted a “Raptor 90SE Warning” back in September last year and Jeff Swartz a proclaimed Thunder Tiger Factory Team Pilot stated he was taking it up with Ace in the USA.

I have reported the failure to my supplier in the UK and await a phone call once they have had a chat with the importers Amerang.

I far as I’m concerned this is a major failing of the model which is one of the most powerful available on the market today. If things had been different for me or any of the other people this has happen too TT could be facing corporate man slaughter charges.

I for one will be reporting this failure to the BMFA in the UK and hopefully they will cover it in their next publication.

I trust TT will own up to the problem before someone gets hurt or worse!

Now I know what your thinking if you got this far. Either you will joint me in my disappointment in the way so many manufactures and suppliers treat our “hobby” and would love the press to start working for us and not them. (I wonder what Jeremy Clarkson is doing?), or your thinking silly old man he doesn’t know what he’s doing it’s all his fault and everything in the RC helicopter garden is rosy.

To be sure I’m getting older but I’m also a fully trained and qualified Tool/Instrument maker trained by the aero industry. Therefore I feel justified in passing comment.

I shall keep you posted & thanks for your time.

I just did the same controlled test you did, but with much better results...things that shook loose were my fault and not a catastrophe. Luck of the draw, or perhaps a failure waiting to happen. Two q's

Re: • Instructions fail to state where the Washout Base Guidance Ring should be secured. (Phasing)

When I put all the links on, this ring seems to find it's own phasing, right? I hope so!! If I've got this wrong, let me know.

And I'm a little confused on the right tail set screws. The ones I have don't have a point on them. I did not torque them down, but locktited them with blue...then put the nylon lock nuts on...which were tight and provided quite a bit of torque. That's the way, right?

Thanks,
Tom

Raptor Tail is Crap
I Love Raptor Helis and own 2, BUT The Tails Assemblies are Bull Sh#t and very dangerous. I use Fury Tail assemblies on all my Raptors after learning my lessons!

Just Love the Fury and other Min. Machines, Build it and forget it - never need to modify it or keep fixing it. Disadvantage here is that I don't know much about the Fury as far as dissembling it so I would need the instructions to take it apart in the event of a crash. I know the Raptor inside out and can completely take it apart and put it back together with my eyes shut because that Dam tail assembly has caused 3 crashes for me. All blew apart in the air. This hasn't happened again since I put the "FURY" Tail on the Raptor. Iam sure other Tails will work on this machine. Raptor is a great machine and everything is enginereed very well EXCEPT for the TAIL. Oh which cost more - The RAPTOR in my opinion. I did the math - The cost of repairs due to tail failure + Fury Tail + New Modifications - My Raptor cost much more.. But I still Love this machine

Yes, lets make ACE aware of this.
