The fact is, this component will do SOMETHING!!!!

It may be small you are right, but to say it does NOTHING is factually incorrect.

sorry to pick on ya

Speculating? WRONG.
There is local filters in the reciever and servos.
If a cap is going to help here, get the spectrum cap,.
you just dont get it... this is stuff I work on all day and night,
people pay me several g's for answers like this.

Come on......

Its a speculation.

"Technically" true but I doubt ANY COMPANY in the US released products without some type of testing due to LIABILITY. Lets take the attitude down a notch please.

I have seen several threads talking about "brown outs" and "voltage drops" It may be to address these issues.

Align has better ways of getting $5 out of you pocket for sure

There is no liability in this product to worry about.
Plus this will have no effect on the issues you mentioned.
Did anybody ever found the direct cause for a brownout or VDrop?

Nope, that's why a definite solution can not be found yet as the true problem has not been determined.

[Finless]

OK just got off the phone with Andy from Assurance.

He sad this was created by Align mostly for 72mhz and sensitive RX's like the Futaba G3. Feedback from the servos run off a switching BEC seems some RX's are prone to glitching.

It is in no way suppose to try to solve brown out issues are anything like what is being reported on the 500. In fact this was made by align for all helis not just the 500.

Now I said to Andy.... "Well you know some are going to balk at this answer and claim Align had to make this because their BEC's are noisy and such". Andy said no that is not why Align made it. In testing they found some RX's like the G3 are more sensitive and they knew going to the manufacturer and claiming this might never get a response so Align decided to make this on their own.

So there is the answer right from the horses mouth! Take it or leave it.

With Brownout issues, moslty are due to radio gear hard failures.
The problem here, there are many areas these hard failures can accure.,
But its a whole lot easyier to troubleshoot the cause, than EMI/RFI/Static issues.

so has andy or align made any comments on the brown out issues? What do they think or make of all the problems?

This is THE question. I do not care about gadgets, let's get answers for THE problem.

(ok, I did not fly my Trex 500 yet, and to be honest, I am not in a hurry to crash my new heli... I want to know what is the problem with that RX/ ESC/ BEC/ STATIC/ TAIL/ DON'T KNOW WHAT problem).

[Finless]

Andy did ask me what I thought as he does see all the reported lockouts.

I told him the many things people have done and in turn have reported success. I told him grounding the BEC to the motor mount has helped some and others have had to ground the tail system and that has helped some. While he sounded interested he questions why so many more (like me) are running stock with no issues?

So no he is not aware of anything "specifically" pointing at a known cause and why the 500 seems to be getting more reports of this that other helis. I think the reason is too many variables and causes...

I explained to him that there is some data people have posted. One of them is Aberdeen's mod which while I haven't seen his data, he says his equipment showed a clean up of BEC noise when grounding the black input wire to the frame. Makes sense to me and did when he posted it BUT it sure would have been nice to post the O-scope screen or whatever to prove it to Align... Might have gotten them to do something about it. Needless to say I told Andy some have had success so far using this mod.

And I told him that several folks have shown data that there "can be" a static problem. One of the guys posted the tools he used to measure it and after grounding showed the results. Others have posted success with grounding the tail system as well.... At least so far.

So I did explain what I thought and what people have posted about here. Now if Align actually looks at this as anomalies? I dunno....
Bottom line Andy said Taiwan has been unable to reproduce any of these problems. Reproducing something before try to fix what you cant reproduce, you have to admit is a problem for them.....

Don't they have quite high humidity there Bob? A dry static prone atmosphere may be the variable that they can't reproduce...

The biggest problem here is that this problem do not show up on every flight. Some fly for 20+ flights with no problems and then all of a sudden, problem accure. Some have no problems at all with no fixes or mods. Some moves things around after the problem or change thing and think the problem is gone. So until we can duplicate a brown-out in flight every time or on the bench by adding more noise or (EMI/RFI/Static), we may never get to the end of this.

Well maybe I can duplicate this test with my scope. How is the noise measured?

Kevin Pm me a contact number ,
get scope and heli ready.

[HeliBurns]

Bob, without a schematic of how it is connected internally, then this device cannot be analyzed..."feedback from the servos" is not an accurate term.....

Is there any way that Andy can get you a schematic from Align in Taiwan? I can't imagine that it would be some sort of proprietary techology....

[Finless]

FYI I am gonna have to go find the posts but 2 guys DID confirm a static issue on the bench 100% or close. One guy said his 6200 LED would blink when he spooled up on the bench. Removing the boom and belt and it stopped doing that. Put it back on and it did it again. Grounded everything and problem gone.

Another guy use a HV probe and registered static at the belt in the tail drive case.

So go find those posts and see how they read the static noise.

Kevin I would LOVE to see the different O-scope readings with and without Aberdeens mod..... We can send them to Andy.

Bob

[tkbr0wn]

Someone in another thread just stated they had a brownout after doing Aberdeens mod. Seems like maybe that mod is the joke of the month.

Sorry, couldn't resist.

I just did it, but I didn't not measure the way Aberdeens said to...

What a POS! I haven't had any brown-outs with my Gaui.

Sorry, I couldn't resist......
