JR Heli Vibe - Airskipper - Sylphide - Venture > Problem Report/Count Vibe 50

Guys, we have heard about some issues with the Vibe 50 here on RR, mainly vibrations, humming and vibration associated- or caused failures.

Please report your problems in a few words and in a counting manner.
That way we can get an overview what happens often and what problems are rare.

This thread is not for bashing but for statistics and finally maybe helpful conclusions.

Thank you all out there.

I am "1",

having had vibrations and humming noises of unknown origin, one spontaneously in-flight broken boom and lastly havy tail vibrations in a completely new boom-tail unit, which was build with high attention and care and with all parts aligned perfectly.
I felt the high performance and great pleasure to fly this thing but all in all I never had the chance to start real training because of so many issues.
Therefore, I went back to my Vibe 90 and Synergy...

Every single problem I had was my fault (non JR parts and solutions). 200 flights, no problems

I had 0 issues until I crashed it, then spent a few flights tracking down the Vibe. After replacing every shaft etc, it turned out it was the tail hub being bent slightly. After that, back to smooth flight.

My swash didn't fit when I put the heli together. It was too tight on my main shaft. My fan hub was also VERY loose on my engine. My seesaw is loose no matter how much I tighten the bolts. This is the only heli I have that has a constant tail drift (I blame the gyro). I also have the Vibe "hum".


... although it is still a very nice heli

Spartan gyro

I would blame the "hum" and say that vibrations are causing the drift but there are 2 more Vibes at my field that both "hum" just as bad as mine with no drift at all.... both are using Solid-Gs.

Also, there are no visible vibes at all... just the humming noise while flying.

1: Tail boom broken in flight
2:Bearing gone out from the strat shaft bearing Block (bearing was locked by the company)
2: Tail boom problems...during flying i have githes (gyro sensitive changeing dosent make any difference)sometimens tail pith control locked in one position expecialy on turning left. Gyro changed for new, Servo changed for new. Everything checked on the groung warks perfectly (gyro futaba 401, servo 9254.)
3: After 20 flights One way Bearing has broken....(a lot of money )
4: After 50 flights every bearing are to change....(made in singapuer why it is the problem)
Well so far so good

about #4

Only the main shaft bearings and the bearing above the pinion are made in singapore. The rest is made in Japan. I complained about this right at the beginning and I couldn't understand why two types of bearings. I got a handfull of oem bearings (probably made in china too) at like $2 per piece but for now everything is supersmooth. The only bearing that when south was the one above the pinion but that happen because I didn't align the engine properly the first time and that bearing was hammered to death by the pinion.

about #3

You should have sent the one way to where you bought the heli. JR one ways don't fail unless something was out of spec. Mine locked up and the entire one way assembly was replaced at no cost by RealRaptors/Macgregors

I have a Vibe and fly it almost daily no problems. The machine is just what I was looking for. A machine that I can burn lots and lots of fuel and go back out the next day and do the same thing. The machine just stays together. I have 30+ gallons thru it.

Save for the tail snapping off after approx 100 and something flights and the occasional humming, i have had zero problems with it, and its been properly abused in flight...

I have had 1 problem with mine just a slight humming and tail hub blowing off in flight. Had a vibe but I put 3 bearings on the tail and it went away. Talk about a smooth tail. All in all a great heli. I have about 8 gal through her now and still going strong. Just ordered a second one and building it now.

I've got 2 Vibe 50's and they've never missed a beat. By far the best 50 size heli I've ever had

Zero problems & total satisfaction !!

I got humming, too, then i took rotortech/funkey-tail blades 85mm and the humming was gone. The bolt holes in the stock tail blades had become worn out, it became a slotted hole.

except the humming, no problems at all.

Yes

I put 3 bearings in the tail. It is so smooth its unreal. Stopped the vibe I had and my humming is practically gone. You have to listen for it now. The TT moves so smooth and free. Good fix and upgrade I can try to get some pics of it. I will have to take tail apart for it so don't know if its worth doing but you should try putting another bearing on it

So you put 2 extra bearings on the torque tube? Or are you saying that you replaced a bearing else where on the tail?

Add another Vibe to the list of no problems at all.

Mine is built completely stock except for the following:
1) Carbon tail boom braces (Was a x-mas present so why not use em).
2) Modified plastic tail boom clamp, to save weight.
3) Updated JR rear canopy breakaway tabs installed to put my mind at ease.
4) Carbon RJX tailblades (Ya ya I know, their cheap and work a treat!), Radix paddles.

I had a slight humm maybe the first 3 flights when the motor was still slobbering rich, that went away completely. I do take great care when building though and spent alot of time getting frames parralel, mainshaft bearings properly aligned, clutch and motor properly aligned, balancing etc.

Setting the bearings for the tail drive-shaft.

I saw this thread and became nervous as in 3 days I pick up my new Vibe 50; after having a faultless run with the 90.

So obviously I've had no problems but I would love to hear everyone's thoughts on this:

Setting bearings with perfect precision.

Some, like the main vertical shaft bearings will just 'pop' in with no dramas.

We all know that a vibration that causes dirt digging can come about from the smallest angular displacement. Or even a 'bad' bearing in the sense that it's not balanced properly.

I don't know if anyone else does this (I maybe the only very weird person on the planet...) but, when I build or re-build the main head I start by sticking the main shaft in a high speed drill. no foolin... I spin it and if it's balanced I move on and add the next element effectively isolating the unbalanced element if in fact there is one.

looking forward to tips !

cheers

The drill has too much runout itself to make something noticable. I'm pretty paranoid myself so what I do is stick the drill on the mainshaft (after everyhing installed ie tail drive, main gear, etc) and spin it up to 3000rpm. If there is something out of balance, you will feel/hear it. a tail rotor/drive that isn't perfect at 15000rpm will show it right away.
