I just like the smell of castor. :D



tailskid -> RE: Article about Castor Oil in R/C Report (11/14/2006 2:49:21 AM)

Me too, especially in the early morning hours and as the sun sets....

anyone know a cheaper place to get good castor oil from for less than $7/pint cuz thats what im paying for BeNOL



speedster 1919 -> RE: Article about Castor Oil in R/C Report (11/14/2006 1:27:45 PM)

If you can find it in a quart it is cheaper by the once. I use blenzall from Comet Kart in Greenfield In. Cheaper--They are the worlds largest kart shop and does a big mail order biz.



Sport_Pilot -> RE: Article about Castor Oil in R/C Report (11/14/2006 3:07:05 PM)

Morgans and Fox will sell you castor oil for about $20 a gallon.



hpi apollo -> RE: Article about Castor Oil in R/C Report (11/14/2006 9:13:17 PM)

$20 a gallon? thats pretty cheap, is it of good qulaity?



Sport_Pilot -> RE: Article about Castor Oil in R/C Report (11/16/2006 5:00:05 PM)

Morgan's is the same stuff they put in their Omega fuels. Fox's is the same as there fuels also. Best grade available Bakers AA.

Hello,I bought castor oil from Brodak Hobbies,it says on label AA,not medicinal.I would think they sell lots of castor oil,the pilot can consider what amounts run best in his engine.thanks shark45

Castrol or Shell M only in my engines.

I trust these companies products more than some of the "bathtub" refineries.

I will only use Shell M in my air cooled Yamaha race bikes. These put out around 76 ~ 80 hp as a 350cc which is considerably more than they ever did on 115 octane (Methyl Benzine added) or the old leaded avgas, while it was available.

The Castrol lubricates exactly the same as the Shell, however, when racing in wet conditions, for some reason which has been explained to me, but that was years ago and long forgotten, the Castrol can cause the water in the air to affect the anodised aluminium throttle slides and they can stick open. Not good.

We still use Castrol R30 and R40 in the gearboxes. When something that is commercially available and better can be found, sure, I will use it. We did, back in 1994 ~ 1996 have access to Elf X-2560, which was developed for the Williams F1 engines. The problems were, it was VERY expensive and even more alarming, carcinogenic.

So, put me in the Castor Oil camp, I think I'll stay there, thank you.

Castor oil is not refined, the beans are pressed, the oil collected, then filtered, and graded. Thats it. However, additives can be mixed with it to modify viscosity, solubility, and other properties.



stratmoto -> RE: Article about Castor Oil in R/C Report (1/6/2007 1:00:15 AM)

Ah yes, my mistake.

I should have been more careful with my choice of wording.

I also see that this has been explained before, sorry about the oversight.

Sig sells AA Castor Oil by the pint, quart, or gallon:

$6.79 per pint
$10.46 per quart
$19.99 per gallon

Sig also sells 20% pure castor fuel in 5%, 10%, and 15% nitro versions; and 25% pure castor fuel in 5% and 10% nitro versions.

It's unfortunate that 25% pure castor oil fuel is ideal for bushed engines like O.S. Max LA series or Thunder Tiger GP series, but it's almost impossible to find at hobby stores any more. I wonder if all of those Avistar Select RTFs at our club would still sound like angry hornets if they were being run with the proper fuel?



Fuel Dinosaur -> RE: Article about Castor Oil in R/C Report (1/23/2007 9:44:40 PM)

AA castor from SIG is fine, Klotz Benol is fine. The article about the bad and evils of castor are greatly exaggerated, misleading and has false data and assumptions. Folks have been using some questionable castor sources and wonder why it is no good. Castor, for those chemists in the crowd, one double bond at C-9 and it is somewhat reactive. Keep excess oxygen out of it, store it in a nice cool dry place and enjoy it. Castors have been used in model fuels for over 50 years now. I try to keep telling folks it is not synthetic vs castor, both have some great properties. Remember that report was written on the bias, and without sound foundation. I.E. It was horsepucky. Ask for AA castor grade, Klotz Benol or a similar very good grade and enjoy your flying. Your engines will thank you. The old fuel mixing dinosaur.[:D]



awdrocks -> RE: Article about Castor Oil in R/C Report (1/24/2007 3:09:36 AM)

Subscribing.

Nice thread.

Ok then AA Castor is the best and to always use it.

EDIT: Sorry about this off subject question but all the right people seem to be here to ask.

What about the synthetic oil? I heard that a good test is to put about an ounce of mixed fuel in tin can or something. Light it on fire, and that the fuel mixed with the good grade synthetic will burn blueish and you should have a perfectly clear clean oil remaining at the bottom when the fire goes out. BAD synthetic oil will leave a dark nasty residue that looks like burned coffee beans, and the fire will be yellowish.

Anyone ever try this?

Give Stan a call he has top grade oils. He can sell you the oils or make any custom mix you want.

Sport_Pilot -> RE: Article about Castor Oil in R/C Report (1/24/2007 7:08:41 PM)

Sounds like BS to me. The color has more to do with how much light is in the room and how much air can get to the flame. Methanol will burn a hard to see bluish flame in bright light, but a bit orange in dim light. More air more blue, less more orange. Just like natural gas, a blue flame indicates proper mixture. I think the dye used in the oil would have more to do with this than the flame. Some are known to change color in bright sunlight, making the use think the fuel has gone bad. Most US synthetics are one of the UCON brand oil, a polypropolene gycol based synthetic. Note that it's clean burning, while castor oil only partially burns.

awdrocks -> RE: Article about Castor Oil in R/C Report (1/25/2007 7:51:38 PM)

Ok thats the color of the flame, maybe I should have not mentioned the color of the flame. What I was most going after is after the flame stops, the residue left. Good oil will leave a perfectly clear oil as opposed to nasty black kinda charcoaled oil at the bottom. I'm going to try it myself see what happens.



gkamysz -> RE: Article about Castor Oil in R/C Report (4/16/2007 2:03:26 AM)

I lerned something about castor oil this weekend. I spoke with Klotz at Toledo. "Degummed" is a term they created. Degumming is a process that they put their castor oil through which reduces carbon buildup. He asked why people in the hobby industry are after "Bakers AA" casotr oil. He said "Bakers AA" is a trademark. Surely enough, googling Bakers AA brings nothing but hobby related hits. I did find that www.bakerbro.com is the old company, they aren't into castor oil anymore. And there is www.caschem.com which say they are related, but no information is available on the site.

Where do you buy your Baker's AA castor oil?

Rubbish, they're either lying or don't know what they're talking about. Degumming is part of the original process of refining castor oil after it's been pressed out of the castor bean. Virtually all castor originates in India and is then sold off to any company that wants it. Castrol in England were the first company to sell castor commercially as a lubricating oil (the name comes from CASToR OiL) and that was about 100 years ago and it was degummed of course.



Sport_Pilot -> RE: Article about Castor Oil in R/C Report (4/16/2007 1:56:22 PM)

The Gum in Castor oil is green. Bakers AA has none and Bakers A does. Bakers AA is the first pressing, that is the beans are pressed till their shell pops open and the oil drains out. The oil is drained away and pumped through filters into containers, this is Bakers AA. The press is then pressed harder to squese out the rest of the oil, which also presses some gum out of the shell and any stems. It has a greenish tint and is graded Bakers A. Drug store castor is Bakers AA which is tested to be sure it has no ricin toxin which is more likely to be in Bakers A. If the oil is truely degummed, then they have chemically treated Bakers A because there is no gum in Bakers AA. It is actually a marketing term. Degummed oil will congeal just as quickly as oil not marked degummed, but this has nothing to do with gum as the congealled oil also has no gum.

Baker is or was the main importer of castor oil in the US, likely the Klotz oil is Bakers Oil which is treated and packaged under their name.

This is Baker's AA castor oil.

I have found that degumming reduces the phosphorus content in the oil.

http://www.wsu.edu/~gmhyde/433_web_pages/433Oil-web-pages/castor/castor-oil2.html

This is the process of production. I don't believe that first press doesn't have "gum". What the heck is "gum"?



gkamysz -> RE: Article about Castor Oil in R/C Report (4/16/2007 5:19:40 PM)

And the jackpot!
