Yuppers, those are the ones...you also need 2 of the BK0584 "thrust washers" I'm not sure what parts bag these come with...but they're 1mm thick washers that make the race from the roller bearing hit the thrust bearing correctly...same washer that goes between the thrust bearing and the rollerbearing in the head.

PV0200 are not thrust bearings. They are radial bearings.

Wonder if this would work?

1 x d5/D10/W3 Radial bearing Part No. SMR105C-Y AF2
1 x 1mm washer
1 x d5/d5.2/D10/W4 Thrust washer Part No. F5-10G

Parts looked up from Boca Bearings.

My only question is the ideal thrust bearing outside diameter should be slighly smaller than the 10mm i can find.

Of course, another way would be to substitute the outside stock bearing on the tail for a bush???

Your call is important to us.

If it's so important, answer the f*ckin phone!

Tday - I use a washer anyway because if you look closely at the nyloc, the 6 points are bevelled which can result in some end play on the bearings because the 6 points barely overlap the bearing inner. The only thing you have to watch out for on assembly is that the washer perimiter doesn't bind with the plastic blade grip. I tend to remove a tiny amount of plastic to resolve this.

EDIT: oops, this was a response to a question from Tday on page 1.

Exploding Raptor Tails Solutions???

I was in discussion about this in another thread (T/R Thrust Bearing Pros & Cons). I have looked into trying the Century T/R. Not sure of the shaft size yet and its a bit expensive, but its being used on other Heli's for the reason posted. Here's the cost:

HI3096B 3 POINT 3B.B T/BLADE GRIPS 2 $10.95 $21.90
HW3098A STEEL TAIL ROTOR HUB – SE 1 $12.50 $12.50
CNBB0930 M3X9 THIN BALL BEARING (2) 1 $15.95 $15.95
CNBB49T M4X9T THURST BALL BEARING (1) 2 $10.50 $21.00
CNBB410 M4X10 BALL BEARING (1) 4X10X4 2 $3.99 $7.98
Total Cost $79.33

Thanks Guy, I'll take a look. Also, the quickuk tail grips look beautiful for sure and don't weigh more than the original parts.

QuickUK tail grips

Search for R6T-11 on the page---it's about 3/4 of the way down.

mmmm nice. I wonder if they have thrust bearings ?
I've got some of the metal TT tail grips which seem quite heavy and would put extra load on the 2 radial bearings so I've never used them

Thrust bearings

Quote 
So it goes:
RB = Roller Bearing
TB = Thrust Bearing

RB - TB - Hub - TB - RB

Just like in the grips on the head.


This is NOT the order of the bearings on the Head of a Raptor 90SE. As a matter of fact, this is not the way a thrust bearing would have its best advantage.

The thrust bearing should be on the outside. It does help to have a smaller inside diameter smaller on the outside but the TT hub, either of them, dont have this tapered. So it would be useless to try to fit a thrust bearing in the hubs by TT.

The best bet is to have Quick UK CNC Tail blade grips to accept this thrust bearing.

And all worries are gone.

I agree with you Flying Tivo. Especially when you look at the alternatives. My point in that other thread was that of cost.

Yeah, I was looking at those SMBs last night. A mate at the field the other day was singing their praises, and uses them throught his helis. I can't remember how many times I've bought TT bearings and they've been notchy

That's the order they go in for the 50. I agree that the thrust bearing would do a better job on the outside...

Those pic's illustrate bearing failure, problem will be solved when TT or someone else comes up with a design that incorporates thrust races just like in the main blade grip.


Someone did, the Hirobo Evos all have thrust bearings in the tails. Perhaps an Evo tail assembly would fit? Maybe just the hub, grips and bearing?

BS BS and More BS,

Here we all are AGAIN trying to figure out a fix for Thunder Tigers Malfunctions First is was a issue with the canopy poping of and now this? I think its time for thunder tiger to start sending fixes for there flaws to people that have purchased there helis. That is bad buisness selling one flaw after another only to have the community come up with a Fix for somthing somthing that casted $$$$

Tail rotors

I don't know the history of those that failed, but do consider if you whack the t/r blades, you may damage the bearings and lead to failure. I've got >500 flights on TT30, 50, 60, 70, 80, and 90 helis w/o a failure, but have had a MA t/r hub fail and 2 Hirobo t/r grips fail. I'm NOT the TT apologist for this forum, but other helis aren't immune to problems, either. It seems prudent to check the t/r before flight and if the bearings are sloppy or notchy, then replace them. A catastrophic failure of a bearing that checked out normal isn't impossible, but hopefully there would be some indication from the preflight that they were failing. Hope this helps. steve.

I agree with Steve...very few crashes on my 50 have been caused by faulty parts...faulty flying yes, but I have had only one crash due to a bad part, and that could have been fixed if I would have caught it earlier.

If you want to crash because the parts are bad, fly a T-Rex. I have had numerous crashed from their parts failing. Just this weekend my tail pushrod pulled apart and caused a crash...don't get me wrong, I still love my T-Rex...all helis have issues, they're not really supposed to fly anyways

Century tail rotor...

Here boy's, this is allot easier to order and has everything you need to upgrade your tail rotor on your Raptor.

http://www.heli-world.com/detail.aspx?ID=3976

RevGadget,
Allot cheaper too than buying all the parts separate.

Only thing is if the shaft diameter isn't the same you'll have to find a way to enlarge something (output shaft or the hole in the rotor shaft).

Later...

Scott!
