fwiw...Hundred of flights on stock raptor tails..No problems...None of these tail assys are immune to ground strikes....New steel hubs are nice, though....

I finally got my new 90se flying this past weekend, had 3 flights trimming her out. an update to the VXB.com thrust bearings that they do have a larger ID on the inner washer and smaller OD on the outer washer just as they are supposed to be. now the plastic grips seem just as loose as the evo grips but once spinning i think they will be ok.

one question is that i noticed that quite a bit of the grease flew out of the grips when i checked them after flying. would it hurt to seal the opening with something like silicone or mount the thrust bearings to the inside (closest to the tail shaft/hub)?

Thanks
James

Sorry, but I hope that the tail works better than it looks. Old and heavy.

Did anyone ever find out if the Century raven tail would work on the Raptor? It has thrust bearings.

check out my new tail system. got from Quick Japan at $120USD, for everything from the tail boom on to the blade grips. i believe the grips have thrust bearings in them. quality is superb, and there's zero slop. it comes with two shafts. i'm using the longer one now, it gives up to 45 deg of tail pitch. it'll be a pity to break it. such a work of art...

What do you mean you believe it has thrust bearings? It either does, or it does not. Take off one of the grips and take a pic of the bearings and we'll let you know

i did just that, but couldn't get the bearings out as the grips are cnc press fit. shone a torch in, and saw two radials, and something between them, like a few washers. the space between the two radials is rather large anyway, i reasoned it was a thrust bearing. i wouldn't bother heating the grips up just to check if it has a thrust bearing or not.

The Gohbee Stinger tail has trust bearings also, and is almost identical to the Raptor tail

BUT, I stil can't see why you're all having problems. I've been flying my Raptors (3x R50, 2x R90) for years now and ZERO tail problems. This was in the std. configuration.
I've also helped over 15 people witht their Raptors and ZERO tail problems there!

Just DONT overtighten the nut, just get the slop out and that's it. NO force is needed.

Anyway, for those who think they need a fix. Get the QuickUK tail (very stylish!) or the Gohbee tail.

Cheers,

Richard

KeeWay/Guy etc..

Further to fitting the thrust brgs I am undecided as to whether it is going to be such a success as hoped..as I have been unable to get my gyro to hold properly since..

I may well have a little run out on the tail drive shaft since throwing the grip & blade as I am getting a fair bit of vibration and there occasionaly appears to be extremely slight stickness on the tail slider. The stickyness is so slight that it is actually very difficult to reproduce consistantly but it is there.

Everything appear to be running true visually when spooling down etc though.

As I was pushed for time I changed the complete tail drive assy from another Raptor as a temporay fix which solved the problem.

Hopefully tomorrow I will get a chance to substitute the parts one at a time to find the problem and get back to you all.

Barney - when I looked into the possibility of employing a thrust bearing, one thing that was immediately apparent was that one of the thrust bearing races would bind in the grip - they're the same diameter. The only solution I could come up with was to remove some material from the grip where the thrust bearing was 'locked' to the inner if you see what I mean. This is why I like the idea of using angular contact bearings, if I could only find some.

Guy, The thrust bearings I have.. the side with the smaller inner hole already has a slightly smaller outside dia too..I fitted them with this side in the middle of the grip to allow it to rotate without grabbing the plastic grip..it's probably only a few thou smaller.. but it is noticable when you place the thrust outers back to back.

Whether it has given enough clearance I'm not yet sure..Another option rather than remove grip material would be to remove a little material from the thrust washer outer edge as the brg race track is central within the flat washer

Tomorrow I will swap the parts over a bit at a time to see where the problem is in my setup

guy/barney

the thrust bearings i got from vxb.com does have a smaller od/id on one washer and larger id/od on the other and in the plastic grips did not bind, but in the metal grips from "CORRECT" did bind.

i have moved the thrust bearing to the inside and flew only one flight today and seemed fine also there was no problem with the grease flying out like i had when the thrust bearing was on the outer part of the hub.

since i am using the sus hub i just took the entire assembly off and put it on my hi-point balancer just to make sure the tail grips/assembly was perfectly balanced, just in case.

i can post pics tomorrow of the bearings if you would like?


Thanks

On a similar but side note.

Anyone know where I can get the Quick UK tail grips? I did not see Ricks as stocking them. Dont want to order directly from Quick UK.
