Default Corrosion caused the crash



A friend lost a plane while float flying this week and it was a result of corrosion on the connector between the battery and the switch (it had bluish green corrosion on the plug from the battery). He lost complete contact with the plane, and then it crashed into the lake. Is there a spray or coating that can safely keep corrosion from occurring on electrical connectors?

I did some searching and found the following:

DeoxIT: http://store.caig.com/s.nl/it.I/id.66/.f

Stabilant: http://www.stabilant.com/appnt42h.htm and http://www.stabilant.com/index.html

Homemade: 80% naptha (coleman lantern fuel) and 20% mobil one 0 weight synthetic motor oil. The naptha is used as a cleaner and carrier for the oil, the oil contains cleaners to clean poor contacts and anti oxidants to keep it from breaking down. Put this in a squirt bottle with a spray nozzle and it will cost about 20 cents a bottle. Works as good or better than the commercial lubricants.

At one time oleic acid was a good lubricant but times change, there are now better products available. http://www.antiqueradios.com/forums/...403&highlight=

Any other ideas?

Thanks,

Ken

"it had bluish green corrosion on the plug from the battery"
That is "Black Wire Corrosion " more prevalent with NiMH batteries than the earlier NiCD.
Always disconnect the battery from the switch harness when system not in use, especially if used/stored in a damp environment. - am external coating of grease will only hide the problem inside the wiring..

Not sure how to correct "Black wire corrosion" because it develops inside the insulation. If you suspect "Black wire" you can strip back the insulation and you will notice the corrosion traveling up the wire under the insulation.

If you do not have "Black wire corrosion" then I suggest you use a product called "Corrosion-X". I use it on all my waterplane electrical equipment. I dunk my RXs right into the stuff, and my ESCs if it's an electric plane. It's great stuff. Do a search on the forum and on youtube. Sometimes hard to find locally. You may have to order it online. I found some at a local ACO hardware store.
