Static discharge sticky

[worldofmaya]

If recall it right, it shouldn't make a difference when using RX or VStabi, because both share the same negative line. Anyway, I'll try the RH proposal...

correct just in some cases easier to find an open channel, thus reason said to rx is all. But yes either is fine, just need an open slot

Connecting to the negative of the receiver using a patch cable is the same as going to the negative lead of the battery. It's an elegant solution. =)

Another opinion I got was that one should use a really thin wire or a resistor between the motor mount and the rest. If there's a short-circuit in the motor (which could happen) the resistor / thin wire should protect RX / Vstabi.

I sure look forward to the day when a fully-grounded tail is designed into the heli...

I have been flying my logo 5003D with Zpower motor for about 30-40 flights, no static issues yet,

I am now considering buying a 6003D - In reading all this thread about static discharge - is there a fix that has been agreed upon or that everyone knows works well. I am curious if there is a particular setup I should follow to not encounter static issues.

Can any elaborate?

Thank you,
Jeff

While I can see the savings in wiring here, is there any disadvantage in that the high voltage is going through the receiver this way?

With the continuous grounding, the static charge shouldn't build up.

Yes it is just ground is all.

I have some static issues with my 500 flybarless. I have graphit 33 but I think I will do the grounding as well. Do I need to run a negatuve lead from the rx to the motormount and the tail boom, or just the motormount? Do I attach the wire to the screws that hold the motor or elsewhere on the mount? What's a good method of attaching it to the boom (if needed also).

Thanks for any help.

billy I'll try to get some pics tomorrow for you man, sorry just been busy.

Hello,

I had the static issue on my Logo600.

Hereafter some picts of my mod. Static problem has now totally disappeared.
Ground continuity between boom and motor mount is ensured by the black ESC BEC wire.

Boom side :




Motor side





Note that my ESC (Jazz 55-10-32) is not an opto ESC, so ground battery cable is internally connected to the black ESC BEC wire (of course, ESC BEC red wire is not connected !! ).

Cheers,
Laurent

[billyd]

Thanks for posting that Laurent. Do you need to ground the esc like that?? What if you did have an OPTO isolated esc and an Rx battery with bec (voltage regulator)? Would you have to ground the bec (voltage reg) and the esc to the motor mount and the boom? Or would just a ground from the boom the motor mount to the bec or voltage regulator (negative lead from rx) be sufficient ??

Hello Billy

The informations I gave in my previous post for solving the static issue came from Mikado some months ago. (I don't remember the name of the mikado team guy)
Very simple :
1 / Ground the boom,
2/ Ground the motor mount.

Just 2 words : it works.


BUT, If you have an opto ESC, DON'T GROUND ESC as shown on the 2 last picts !!!!

==> If you have an opto ESC: connect the ground black wire of the ESC BEC to the motor mount, BUT NOT the Battery black wire

My understanding of this issue is that it is necessary to have the same static potentiel (not sure of the word...) from the boom to the motor.

To have a perfect Logo anti-ESD system, you can add a little resistance (50 or 100 ohms) on the wire coming from the boom (second pict), to avoid high current pulse when a electrotatic discharge occurs. (resistance is still not added on my logo ... one day perhaps... lol )

Hope this helps.

Sorry for my "Frenglish", I do my best...

Cheers,
Laurent

Nice explanation Laurent!!
After a little glitch with my VStabi Logo, I connected the boom with motor mount and used Graphite 33 on the belt. I've done this on all my helis now, just to make sure
The main problem if you're using Fasst is the VStabi unit. The 6014 Fasst receiver should be resistant against these issues. That was also what I had when my Logo had his little problems. All VStabi functions where affected.

I also ordered MIK3046 which is an antistatic tail drive pulley for the logo 10, 400, 500 and 600.

I got it at www.mikadoheliusa.com right before they sold off the rest of their mikado stock. I wanted to buy another one for my soon to be built 400, but when I went back to mikadoheliusa they sold off all of their mikado inventory.

Readyheli is the only USA mikado rep now but Readyheli didn't carry the part. So I emailed them this past weekend and they responded Monday morning that they will be carrying the MIK3046 by the end of this week. They are a great retailer. Very responsive.

So if you are in the USA and want the antistatic tail gear check Readyheli and it should be there by Friday, Dec 19th.

[OICU812]

Laurent, so I have this perfectly clear, you connected the ground from your esc on to the boom, then you also connected your BEC negative to the boom as well, is this correct?

They are showing up at Ready Heli now Billy, here is a link. Ready Heli

What is different about this pully and the one that comes in the stock kits? They both look like they are made from the same Mikado style plastic.

Just curious since I am planning on a L400 build in the next month or so.

They look to be made of a different kind of plastic. They have a different kind of color (still black but more gray in it). It says specifically on the packaging that it is an antistatic gear.
