This was more a general battery enquiry, rather than specifically for planes. But thanks.

Thanks Andy. I found out about the Mag' sulphate. I have heard that pulsing AC into some batteries can help clean the plates. A lot of this is too new for me as I haven't done much on batteries recently. There is only so much I can learn. ;) That link was sort of helpful but I was a bit confused with the chemical reactions. But I'm getting my head around it slowly. There is the "Trick" too that in DEEP CYCLE batteries, that the plates don't go as far down - or the batteries are "taller" - so any gunk from the plates falls down into the empty area and not shorting the plates with each other. Or so I am told. But back to what you were saying: Adding the salt would change the PH and/or SG - wouldn't it?

Bruce, I read your post: Although I haven't checked with an oscilloscope, I would expect these capacitors would smooth out the peak pulses. That's what capacitors do. Errrr.... No. That isn't what they do. Well, not the SMOOTH OUT PEAKS part. If there are spikes, they will not reduce them. Capacitors WILL smooth drops in the voltage, but can't reduce spikes. COILS can do that, but it gets difficult to do it because a lot of maths comes into it.

But flying in formation has its own set of problems too!!!! There are tradeoffs on how things are done.

Folks, I'm jumping in here feet first. While bored, I was looking on ewe tube and there were some posts about batteries. I'm from the "Lead acid" genre and know about Mallaroy batteries way back when. Now there are SLA, LIPO, NiCad, GelCel, and so on. The order is just the order I recalled the types. So I'm a bit confused: If you have an old lead acid battery which is "dead" (or dieing) they show taking the acid out and replacing it with EPSON SALTS. Huh!!?? Quick trip in the time machine: School teachings. There are three kinds of PH: ACID, BASE and SALT. I don't remember the exact definitions etc, but bear with me. I get that in an ACID battery, the two plates react with the acid and that causes the electrons to create a charge. So: If you replace the ACID with a SALT, ...... HOW will it work? Granted there are ALKALINE batteries. And they would use a similar principle to how ACID batteries work, but there would have to be SOME differences in the equation. I know the "trick" where you get vinegar and bi-carb to make carbon dioxide. Isn't EPSON SALT much the same? The fact it has SALT in the name must count for something in where/how it fits into the three definitions of which I was told at school. So, could someone give me a bit of a hint/push/help on getting to understand how it works?

This is an interesting use for beer bottles. http://www.loopinsight.com/2014/06/05/what-to-do-once-youve-finished-all-the-beer/

Interesting. To me: Twit - fool. Twat - part of female anatomy. Twot - acronim for Total Waste Of Time.

Anyone watching it? Episode 2. The reporter flys out to....... where ever. (Starts with L) and there is a small yellow plane in the background. Skyfox, gazelle? Anyone?

Haven't watched it, but from the comments, is that the one where the guy is standing there hand on copper and it circles him? Yeah, great flying. Shame the fun police have stopped it.

Yeah: It wasn't a Cessna this time! ;)

I'm (kinda) at work. As much as I am allowed a few indulgences, I can't spend the day doing searches on shows. I'll try to remember. I am close to "OVERLOAD" with other tasks just now.

Well, maybe. I have been wrong before - I think. ;)

But the shots of inside the cockpit showed it IS side stick controlled. So the question remains about the Air Crash Investigation episode which showed an (aledged) A350 cockpit with a yoke control. And it was a LONG TIME AGO too!

Ok, here's the thing: I watch Air Crash Investigation. ALL of them! Don't know when, but NOT recently there was an episode and it was an Airbus plane in the story. There was a cockpit view and HANG ON!!!! There is a YOKE! Can't be an Airbus! They have side sticks. I think I know enough about the differences between Boeing and Airbus! And the people who make "ACI" aren't that cheap to use incorrect cockpits! Later it was said it was an Airbus 350. I know the Airbus 310, 320, 330, 40 and 80. But hadn't heard of the 350, so accepted it. Now Airbus are saying it is their new kid on the block. Huh?

I've flown into Hotham twice. Just ring and inform them. They don't mind. It is a short bus trip to the "fields" if you want to go skiing. Nice people. They helped me with fuel there too.

I was in hobbyco today. I was looking at the models and finally realised which plane I had seen. I knew one of the airbus planes had a "weird" set of wheels. A MIDDLE set. Now I know it is the 340. But looking at the models, there are two kinds of that too! One has a single set of wheels and the other has two sets of wheels. Comments?

'twas just a suggestion.

Um, I'm scratching the brain cells, but instead of tracking from the "dam" to Q1 and having that height restriction: Why not keep going north. Sorry can't find my charts. Go up towards Watts Bridge then go South Stradbroke. It keeps you over ground longer. You just have to watch out for a little airstrip somewhere near the northern bit of Surfer's, just south of Sea world. I haven't been that part of the world for a LONG time now, but flown past it about 6 times. Good luck.

Marty, So: Who's a Doctor Who fan then? ;)

And another question: (Though I don't mind) Why was it reported in a Kiwi paper and not a "local" one?

For anyone up tonight ABC2 has a show called "fear of flying caught on camera" at 21:30. From the shorts it looks funny.

Found this on the tube: And, it was done here in Oz. I'm impressed.

eightyknots: I don't think that would be a good idea, Coz the other person may ....... take offence. (think about it)

Yeah, well on the other side of the coin: If she offers you one, but DOESN'T allow you to pick a name, be careful in accepting, coz you just don't know who the third party will be - or more importantly: The sex of said party. That is: ACKWARD!

Thanks. Shall do.
