I had problems with original onewaybearing and HGonewaybearing. So I shifted to this one from Correct 016-1422 DRIVE PULLEY 50T (WITH ONE WAY BRG) . I run a West50 in the Caliber.

After 3 failures from 2 separate stock units and many $$$ in parts.

I bought the Correct 016-1422 DRIVE PULLEY 50T (WITH ONE WAY BRG).

2 full seasons and nary a problem...

Ok, what should I do?

I had a pretty bad crash last weds trying my first attempt at an inverted hover. I want to say the cause was the stock one way slipping because when I got it inverted at about 40-50ft, (hoping it would give me enough room to correct any errors), the helo started slowly decending like I was autoing. I kept giving it more neg collective to pull out of it and it still came down. At about 15-20 feet I tried to flip it back around but the helo acted like I didn't have enough head speed to do anything with it. Oh yeah, yes I was in Idle up mode. LOL. Reason I think the oneway was slipping and not my pitch settings, is when I put Idle up on while I'm on the ground and give neg col, it has enough pitch to compress the landing gear a bit. Question is, I'm on a real tight budget and I have about $80-90 worth of damage. Should I go ahead and upgrade the bearing and gear and jack my cost up to 150 or so or should I clean the bearing real good and try ATF? Is there another way to check the bearing besides listening for it to slip? (Visually). Thanks for the help.

If I were you I would get the Correct Gear and Oneway, and be done with it!!, This will give you peice of mind, and save you $$, avoiding any future problems!, I think RCHeliworks has them in stock.... Well worth it, in my opinion........

You can tell best by looking at the shaft where the bearing rides. If it's shinny and polished looking, or worse yet scared and blueish in color, or flakeing, the bearing is slipping. If it's just real shinny (like mine right now) I just used 600 grit paper and scuffed it up and am trying the same bearing with ATF. We'll see how that goes. Do you have a ptich gauge and know fur sure that you had enough negative pitch to hold your heli up?

I know this is a stupid question.....but were you maybe giving to much negative pitch while trying to hover inverted? The reason I ask is that the first few times I tried it, I noticed that was getting nervous and putting almost full negative pitch which degraded my headspeed. Once I realized it I was able to manage the headspeed and hover fine inverted. Just a thought.....

Are you using the HG upgrade bearing or the stock? If it's the upgrade bearing I would look for signs of damage to the rollers, clean and lube it with ATF and give it whirl!

If it's the stock one-way bearing...then PM me your address and I'll send you another stock one to replace it for the price of the postage if you want (since you're on a tight budget).

If your one-way was slipping, your engine would have lost at least some if not all of its load. Assuming that you are not using a governor on your machine, the failure would have been accompanied by the sound of your engine revving out, and total anxiety rushing through your body.

You did not mention that the engine was screaming as you were going down. It is possible that your one way is fine and perhaps your pitch, technique, or "other issues" may be the cause.

The correct upgrade has the potential to save you BIG time. If you are convinced that it is the one-way, or even think that it is a possibility REPLACE IT! A little more money now ... or possibly a LOT more money later.

If you decide to go for the one-way upgrade... make sure you also replace the counter shaft as well.


Thats my 2 cents...

Alright I got the bearing cleaned up and put ATF on it. Now for my hard headed , can't see what your saying brain can you explain how you guys think that by putting oil on the shaft just above the one-way bearing that the oil will ever GET to the bearing. It looks like to me the counter gear hold two sealed bearings, one above and one below the one way. Now how does the oil get thru the top bearing. I mean if the bearing is good the inner race will fit tighly on the shaft and spin with the shft, that is'nt much room for oil to get thru. I'm not sayin what you guys are doin dos'nt work,,,,,I just dont understand HOW it works,,,please help

Wurthless,
I use a hypodermic needle to squirt some in mine. My father when he was a live had sugar and when he passed there were some needles left. the nice thing about the needles is that you can get what ever liquid you have in them into the tightest places.

Yes I also have a needle to get to the shaft but,,,my question is HOW do you get the oil thru the top roller bearing down to the one-way. The one way is sandwiched between two roller bearing, one on top , and one one bottom. Not much oil can get thru those bearing to ever get to the one way as I see it...my brain hurts,,and worse is my bearing is still slipping,,,,
