vibration analyzer
We are purchasing a new Bell 407. We are also buying a blade tracker/vibration analyzer. Would appreciate any comments or opinions on the various makes and models available (RADS, CHADWICK, DSS, etc).

Don't go cryin to Bell if you can't work the rotors with something else but the RADS and want warranty support. RADS works best for all of the 4 bladed Bells hands down over the others. You get what you pay for...
There is another new player in the field called IAC, their model is called the 1087 and is priced near the RADS and VXP. They also make the vibe portion of the new 412 onboard monitoring system (BHVM) that Bell/AAI recently STC'ed.
Regards,
Chuck

As Chuck..... said if you want to do a 4 blade Bell use the RADS , have used and like the chadwick 8500c but have had problems on 412's and 407's with it and have had to fit the RADS to get the job done, there are better systems but Bell support the RADS with info, software etc they don't support the others!

We leave this sort of thing to our Engineers. They seem to know what they are talking about. Funny isn’t it how we get to think we know after a while when really we would not have a clue.

Three or Four bladed maybe. I wouldn't recommend the RADS system for the 206 though. I think their system has some issues. I spent 3 hours over two days last weekend dealing with "Rainman" (a tenth at a time) trying to get one of our L-4s sorted. It wasn't the first time either. If anyone else was willing to let us test one of their systems, we'd probably buy it. (We run the AS350, 407. and 206)

From engineering experience on four blade systems I would recommend the Chadwick Helmuth 8500C+, Its easy to use and you can add all the goodies you want, from basic blade track and balance through to a full 12 sensor airframe vibration analysis which can help pre empt component failure. If its easy to use then you will save money on labour costs - I have seen some amazing things done with this system.
In saying that I can't say I've used it on elastomeric heads........

Bell has invested a fair bit of effort developing and configuring RADS software for their products.
If you want the light helicopter product support managers angle on the matter see page 4,5&8 of this Newsletter
http://www.bellhelicopter.com/en/sup...b/rz100102.pdf
And note here the 407 configuration software is kept up to date by Bell.

If your engineers are having a problem with a MM procedure using Bell software they need to get in touch with Mirabel. Like Chuck says if you would like their ear on a vibe related warranty issue it’s the system they prefer to support. Make sure you have a comprehensive data and move inventory to support your case.

The 8500 is an easy to use, very practical tool. If you had never used one, you could pick it up, and use it immediately with great results.
The Microvibe is the best all round piece of equipment I have ever used, but I find the controls are not intuitive (to me anyway) and if you are not using it continuously, you have to learn it all over again.
I have used the VXP, but I have to tell you that I had a serious problems using the solutions it proposed and the outcome it generated. In fairness, I suppose that I have experienced some problems with every system that I have used if it is followed blindly, without a little bit of operator intelligence.
Sometimes track and balance adjustments don't all move in straight line mathemetical functions, and there is no replacement for a little bit of human brain power, intuition, and suck and see!

Personally I'd go with the 8500, it's tops!
Can't speak for a 407, but have had absolutely no joy with Microvibe, and am not a big fan of RADS.
Go for the 8500 with the smart track camera it may be more expensive, but it's proven and it works!!

I too like the 8500c with Cyclic Hotline and Helieng , but........as I said earlier if your doing a 407 or a 412 you need the RADS , I can give about 3 examples on a 412 and 2 on a 407 in the last 2 years were the 8500 couldn't get the a/c in limits we had to fit the RADS kit and it came in, this is a case of buy the equip the manufacturer recomends not somthing else.
We use the 8500c's on 206,206L, 212, 365's ,S76's and Super Pumas (when Hums fails) and it works great and we have a RADS kit just for 407 and 412 use which was bought just for the Bells because of past problems.

Vote for RADS, bell will not give you warranty unless RADS is used.
And it works very well... AND 407's have all the sensors built in, all you have to do is hook up the rads to the left of the front pannel.

RADS is the only thing approved by Bell for the 407. Remember, just press DO!
