Adding three ounces of oil to a gallon increases the total percentage by a bit over 2%. 1 ounce increases it less than 1%. Both of these are negligible amounts. I fly in the winter and it gets cold up here. I use nothing but 20% castor fuel. Temperature makes no difference in the consistency of the fuel. I have put fuel in the freezer at zero degree overnight and it is still nice and "watery" with no thickening.

The amount of oil that gets on a plane after a ten minute flight isn't really all that much. After a days flying all it takes to clean it off is a couple of paper towels and a few squirts of 409. Think about this 20% of 8 ounces is 1.2 ounces and of that amount, very little ends up on the airplane.

Now I will say this. In the winter when it's cold, the oil that does end up on the plane is thicker and a bit more difficult to clean off but not enough to traumatize anyone.

Now that's what I'm talking about!!!!

Nice post Aero...



Flyboy Dave -> RE: Article about Castor Oil in R/C Report (7/16/2006 5:04:30 PM)

I am going to post this again. Some of you Guys must have some castor
bean oil oil around, and perhaps some other auto oils, maybe some synthetics.

Give this a try: [;)]....A Simple Oil Test.


Do you think your brand of oil is good? Try this test...take an old cookie sheet,
or a piece of tin sheet...put a few drops of castor bean oil on it ( about the size
of a quarter ), then put your favorite oil next to it...about an inch away. Now
take a flame of some sort ( a cig lighter will work ) and put the flame under
the sheet between the samples. The bean oil will run TO THE HEAT ! Your oil
will probably run away from the heat.( Mineral and synthetic oils usually do ).
That's why fuel manufactures use Castor bean oil as the main lubricant, and
fillers such as Klotz as a base.

FBD.

I know my oil is good. It's Bakers AA and it is the best.

Because it'd be commercially futile promoting CoolPower fuel when it's pragmatically unobtainable, one might suppose thats why BW perpetually mentions CoolPower oil ....except when he's writing an promo article for another advertising sponser selling an alternative brand product when surprise, surprise Gomer....guess which brand fuel and/or oil distributed by which distributer rates the mention during the "engine test" exercise and review? Of course it could all be consistant coincidence and the Easter Bunny and Tooth Fairy might be real..just I haven't seen them yet.



BW addressed my letter to Gordon Banks RE "He is doing a disservice to your readers." I don't suppose Gordon has time between pizzas, flying, writing his articles for his magazine to read RCUniverse. If he did he would get an ear full. I suspected BW and now I know what he really is, a prepaid journalist.

Botton line, some Castor is good, a lot is messy; none is dangerous and can lead to premature wear in alcohol engines.

I just knew beans were good for you. Just do not eat any fresh or dried Castor beans, deadly poisonous -- Ricin. The oil from pressings is okay. Used medicianally on a lot of us for years. Youngsters do not have to suffer as we did. Perhaps BW has been using his Castor for iternal problems rather than in his engines?

Cheers,

Chip

Where are all you "oil tester guys" ? [8|]

They're out racing their cars and buying a new engine every weekend :D

Brian....I know you have different oils laying around....[8|]

Try the castor oil heat test, and report back....OK ?

FBD.



tailskid -> RE: Article about Castor Oil in R/C Report (8/1/2006 2:37:31 AM)

Anyone try that heat test with Byron's Fuel? I've heard it has a pretty low oil content (but high quality oil)....



loughbd -> RE: Article about Castor Oil in R/C Report (8/1/2006 3:18:05 AM)

Byron's fuel does have a very low oil content.



Flyboy Dave -> RE: Article about Castor Oil in R/C Report (8/2/2006 7:27:42 AM)

Nobody has any castor oil around ? [X(]



downunder -> RE: Article about Castor Oil in R/C Report (8/2/2006 5:03:55 PM)

I've got plenty of castor but nothing to compare it with :)



Flyboy Dave -> RE: Article about Castor Oil in R/C Report (8/2/2006 5:33:39 PM)

Don't you have some regular motor oil for the car ? The whole point is, the
castor runs to the heat, the other oils run away from the heat. When I first
did this test back in the seventies I was in the motorcycle shop, and I had
several different type of oil to play with.

You always hear...."the castor oil will save the engine during a lean run".
This is because the castor runs to the hots spots and lubricates where it is
needed most....that's the really neat thing. The other oils run away from
the hot spot....and you have the scuffing, wear, and eventual failure.

This is why most racing engines run straight castor. [;)]

british bloke -> RE: Article about Castor Oil in R/C Report (8/2/2006 9:24:43 PM)

hi surely its the damp/water in the air that causes the corrosion, as far as i know any oil coated surface stops corrosion- never seen a rusty sump in a car engine, if this guys engines are going rusty they must be shelved for a hell of long time so he cant be much of a flyer can he?
if anybody is going to worry about an engine going rusty cos they not going to use it then they might as well sell it, engines are fairly priced, just not worth worrying about, sounds bit of a tight-ass to me, just my opinion[:D]



D Bronk -> RE: Article about Castor Oil in R/C Report (8/2/2006 11:12:07 PM)

I`ve only read this 1 page, but I hope the Fellow that started a thread this morning ,about his LHS telling him that Castor oil was a thing of the past, and an all synthetic oil in the Glow fuel,is the way to go, reads through this Thread.He`s from Japan, I think..He`s running a High RPM, Norvel 0.061" .I`ve gotten over 21,000 Rpm [:@]out of mine, and she`s gaing RPMs still.[>:].A total of 10 ounces of fuel since new.. Here`s a chart I made up, of some testing I did,on the same type engine,a BigMIG Sport R/C 0.061".2 ounces to break it in, and the rest of the runtime, was at W.O.T. and is detailed, and recorded, on this chart..Check it out Guys ,you know, She`s got to be Hot, at these speeds ,and bolted down to a table.I also let the engine run(to get Temp.up) for a short while, before taking my readings.Unfortunately, I didn`t have a means, to measure The TEMP.[:o] But I did use different types of fuel and quantitys & percentages of oil.

I found this link in a search for information about castor oil. It doesn't appear to be quite a simple as it seems.

Sorry mistake post.



Bone -> RE: Article about Castor Oil in R/C Report (10/27/2006 4:54:40 AM)

I got 15 litres of Castrol M castor (about 4 US gallons) under my work bench - I will use it all & then go out & buy some more. I've also got 6 litres of the synthetic stuff. Will use a combined mix of each in my engines or fuel containing 100% castor oil but not fuel containing synthetic oil by itself.




hpi apollo -> RE: Article about Castor Oil in R/C Report (10/28/2006 4:53:12 AM)

i run mostly castor in my fuels, it is just superior, but has anyone had problems with engines that have internal one way bearings and run high castor oil fuels?

Not so far. My son is using 20% castor and zero nitro in his pull start .28 car engine (Hyper 7) and I must admit I'd never even considered there could be any problem. So far I think he's only run about 4 or 5 litres through it though.



rajul -> RE: Article about Castor Oil in R/C Report (10/28/2006 5:51:21 AM)

Dave, that sure sounds like an interesting experiment. Is there any explanation why castor oil moves the opposite way?



Flyboy Dave -> RE: Article about Castor Oil in R/C Report (10/28/2006 6:23:52 AM)

The castor oil is like a fireman....it runs towards the heat....

....everyone else runs the other way. [8|]

FBD. [:D]



loughbd -> RE: Article about Castor Oil in R/C Report (10/28/2006 7:01:53 PM)

What is a one way bearing??

"95% of all statistics are made up on the spot". Where did you get that statistic???



w8ye -> RE: Article about Castor Oil in R/C Report (10/28/2006 7:23:08 PM)

Bruce,
If you don't know what a one bearing is, you must not have very much experience working on model airplane engines?

They also have other names like roller clutch, dog clutch etc by some people. They are on the gas engine that you wind the prop backwards against a spring and release the prop to start the engine. Just like on the Cox Babe Bee with the spring starter.

To be fair, you're not going to find a one-way bearing on your average model airplane engine -- it's only the autorotation clutch in helicopters and pull-starters in buggy engines that use them regularly.

There's no application for a one-way bearing in your average 2-stroke or 4-stroke model airplane engine at all.
