Al the auto bearing on the gents heli had a crack in it and only under the power climbs and other power extems would the bearing slip.
just trying to give some other ideas to what the issue could be.

Hey I didn't ask for this fetish.!!!But I'am sure paying for it....

I understand. This is the only case I've heard of on a rap60/90.

I am agreeing with Scott on this one. It sounds to me that your needle bearings in your one way are slipping on the sleeve. You also stated that is was kind of cold there which would cause the grease in the one way to get thicker and cause the bearings to be slower at releasing to grip. A way to check this is to pull the one way out of the main gear and remove the sleeve from the inside and give it a good degreasing. Try lubing it with a lighter oil. I use ATF on mine and have never had a lock up or any slippage. As for the clutch I dont see how you could have it slipping only after a gallon and a half.Unless you have had a few hot starts. I have a few cases of fuel on my current clutch and have never had one slip or break for that matter. I have only changed them out because of crashes and I only lost the oneway in top of the clutch once because of forcefully trying to start my YS on those cold high compression days.
Hope this helps

A oneway Torrington won't slip unless the case is broken. Even so, the bearing is pressed into the hub, so the rollers can't push the cracked case outward, as in the Hirobo machines where the bearing is a loose fit in the hub. If the bearing is going to slip, it will be on the ground, not under power. I'm not saying the condition that Scott describes is not possible, just never heard another case like it.

fwiw..

Here is one of the FEW instances of TT dropping the ball...(flame suit on)
Stock R90 clutch has up to .015 clearance, making for way too late engagement...I recommend getting the blue TT liner, cur card or paper stock to fit, then assemble paper and clutch liner in thickness sufficient to allow .008 or SLIGHTLY larger gap on each side. (Clutch Dia. +.016")...Use 30 minute epoxy to glue in the shim and liner simultaneously, use the old masking tape around the clutch trick to press the new liner firmly into contact with the bell. (I normally use a layer of saran wrap to allow easy removal as well.)
( You guys ever notice I love parentheses?)

P.S. If you need to remove the old liner, soak the clutch bell in acetone overnight...
P.P.S...Al, I'm still using the defective TT auto hub upgrade!

I have a .020 clearance between the clutch and the clutch liner right now. I'm pretty sure it was the clutch slipping, but we will find out for sure in a couple of days. Thanks again for all of your suggestions. I will keep you updated on any further news.

Regards,

Michael

Sounds like Mr. Al is a litle sensitive about the team Raptor site. ONly cause he got burn over there already and has only made about 5 post.
It's OK Al someday you will be loved by somebody just not any time soon. Try keeping your out spoken thoughts to yourself sometime then maybe people will listen to you more.

Aim, you don't see how the clutch can be slipping? Your one experience with a Raptor clutch qualifies you for? Could be the auto bearing, though, Sensitive? Yeah right. A swartz, or a seneca can't hurt my feelings, sorry. Look at it this way: It gives them something to talk about, 'cause there ain't much happening over there. The Raptor forum here, gets more activity in five minutes, than the "team" site gets in a week. Stephen, you can quote me on that one too. Actually, I received more PM's yesterday, than total number of posts on the "team" site in a week. They're rockin' for sure.

no love

Your right aim no love at all for AL, for one his is a keyboard pilot and loves the attention here the team sight is a straight forward in its answerers like the one I am giving now oh and AL there is more to life than post counts and pm’s and if you decide to play nice and not bash stuff Jeff may let you back now on to the help that was need. The problem you are having is not the auto unit but the clutch to liner gap is to big, two thing you can do first call ace and speak with Anthony in service he will take care of you, tell him what is happening ask him for a new clutch bell and liner, the one way might be slipping but that would make a ratching nose when you start the heli let him know that I told you to call, TT serve is first rate. The second choice is if you need to fly this weekend take a very thin piece of brass you can get at your LHS epoxy that in the bell this will reduce the gap then epoxy the liner on top of that this is a quick fix I would still have you call Ace and get a new bell reason is that at times the bell are cut out to deep and the clutch cant wing out that far to engage the liner and will slip the same thing happen to me on my back heli not a big deal but a pain yes hope this helps, I will not post again about this if you need more help pm and I can help more Dino

Dino, your help really isn't needed here, thanks. The Team site a bit boring? I know, not much happening. I have no interest in the team site, or Ace's little puppet show. We've all done just fine with our Raptors since they came out. We'll do just fine in the future. The fact that you need to come here, tells me a lot. Since we're on the subject, and we have one of the "team" puppets here, can you tell me what sending it to Ace is going to accomplish, except getting another one of the same? No other helicopter in history had such clutch issues. Maybe QuickUK will come out with a clutch bell also. I'm confident they can set the gap clearance correctly.

diapers for Al <edited>

Al, your ponderous excretions serve well as reminders that on ANY forum, your posts must always be taken with a grain of salt.

I for one am frequently annoyed by your occasionally narrow-minded approach to the simple act of sharing information, and I'm not alone. That certainly won't stop you from excreting again, not only here but on other forums as well. Some folks just can't help themselves. There's a word for it.

I'll send you some adult diapers. It's the least I could do, considering your equally ponderous contribution of USEFUL information here over the years.

Check your mailbox on Friday -- or would you prefer UPS?

By all means, put me on your Ignoramous List, or better yet, un-sub from RR, as I've un-sub'd from the Team-Swartz site. Your personal attack puts YOU in an unfavorable light , not I.

without getting too deep into the on going fight, I am interested in hearing more about the auto hub slipping. I have a R50SE that was doing some "strange" things recently. I would begin to spool up and and all of a sudden it would seem like the clutch would just release and the motor would over rev while the head speed slowed down. Shut things down and checked it out and things seemed fine. Started machine and held head while raising throttle and definitely no clutch slipping. Spooled machine up again and things are normal. This phenomena happened 3 or 4 times so I was starting to suspect the Auto hub. After reading this tread, I'm beginning to lean more this way. Now this may be the $64 clue......I did grease the hub before assembly as I had done with all my previouse helicopters. Do you think this is contributing to the problem?

You may want to check if the motor was running backwards. On another thread a few 50 Hyper owners (including me!) have had this happen occaisionally, usually when the engine is running rich and its cold outside!

Castle, when greasing the hub doesn't work, try cleaning out all the grease with spray BrakeKleen, and lubing with automotive automatic transmission fluid only. The auto "bearing" rollers are sticking in the grease, preventing full lock-up.

call ace

Call Ace there customer Service is great, In regards to the 50 yes it is slipping not a big deal but a pain yes, Anthony or anyone in customer service can help you out. Explain what is happening, they will send you a new auto unit, they did have a run of some huds on the 50 that where slipping. Use lightweight oil or atf as stated above on the 50-auto unit.

Oh what is the reason to call Ace and get a new one its call customer satisfaction.
