RaceCity -> RE: Article about Castor Oil in R/C Report (4/16/2006 4:05:13 AM)

FlyNBHappy....you seem to offer the notion that there may be some variability with Bakers AA. Running "several batches"with no rust ???

I've run the stuff consistently for almost 30yrs and haven't seen a problem, so use it with abandon! It's an old, tried-N-true product. It's good stuff.

FWIW...I've run BeNol as well in some other engines and find it to run well, albeit nowhere near as clean as Bakers. For the price, BeNol ought to be sensational, but it seems no better than Bakers, and Bakers costs less, PLUS it runs cleaner in my experience.

Go figure.

RaceCity,

Thanks for an answer about BeNol that I can actually use.

Oh, My. What a rousing discourse. I wrote R/C Report and they had the guts to print my letter in this issue. After reading our Aussie fiends comments about Brian Winch, I was right to begin with, some castor is good, no castor is bad.

I too sensed the hype in Brian Winch's writings, none of that in Clarence Lee's writings. BTW Clarence Lee has designed and manufactured engines, I rather think he qualifies as an engineer. Don't know squat about Brian Winch except what I have read. What I have read makes me wonder.

I hope Gordon Banks reconsiders him. Probably has a contract and is stuck for a while. To good of a report to continue with a questionable contributor.

Cheers,

Chip

Race,
My intention was not to degrade Bakers AA castor, but to state what I've been using all these years (never used Benol....quite expensive as you stated). Mainly I run 20% castor/syn lube, but once in a while I'll mix a batch of 20% all castor. That was what I meant to say.

As far as cleanliness, my Baker's is still very messy. I don't think there is a "clean" castor oil.



Jim Thomerson -> RE: Article about Castor Oil in R/C Report (4/17/2006 3:26:34 AM)

It is castor oil's job to go through your engine, lubricating all the way, and emerge out the exhaust unchanged except for carrying off some heat. So it gets on your airplane and does its best to hang on when you try to remove it. [;)]



griz11 -> RE: Article about Castor Oil in R/C Report (4/17/2006 8:40:52 AM)

I run R/C dragsters and use castor only in my engines. We do some crazy things to our engines. Like using 55 and 60% nitro and very little oil 3% or less. Synthetic just doesn't hold up to this madness :) The runs only last a couple of seconds for a very slow one 1.6 seconds for a competitive run 1:10 track which is 132 ft long. I've used Klotz and Castrol castor in my motorcycles and Castrol in my cars for ever with no problems in any of them. I think the problem when you get a lot of carbon from castor is overheating the engine. That formula in a previous post tells you why. If you get the heat and pressure up enough to break those bonds all you have left is carbon. That is the only time I see any deposits in mine. I tear down my engine completly after every race clean it out with B12 Chemtool and let it dry before reassembing it using a little castor. I started doing this because I noticed if I didn't the crank wouldn't turn as freely. I attribute this to the castor left in the engine starting to gum up. One guy at our track runs no oil in his top fuel engine during the actual competition. He runs 3% for the practice and switches to none during the rounds. Certain brands of nitro have a little lubricant in them for blowers. If you use that you don't need oil in our sport. That engine ran for over a year won the biggest event last year and finally gave up a bearing a couple of weeks ago after a run-away. Castor only in that engine. I don't think the synthetics would hold up. Castor might be sticky gummy goo compared to synthetic but it protects and sticks to parts better than synthetic in my opinion.

loughbd -> RE: Article about Castor Oil in R/C Report (4/28/2006 7:15:04 AM)

Chip, in which issue of RCR was your letter printed?? Never mind, I found it, the May issue. Love Winch's answer. There is no synthetic used today that has a higher flash point than Castor oil like he says. Castor burns and leaves and ash hard enough to scratch chrome???? Oh, puleeze. It leaves CARBON and the only carbon that hard is Diamond. Maybe we have little diamond makers mounted on out airplanes. Hey we can all be rich. I'd sure like to see that ash. I could use it for a grinding compound with my lathe.



Phil Heller -> RE: Article about Castor Oil in R/C Report (5/20/2006 7:38:32 PM)

I will not run an engine unless the fuel contains at least 5% castor in the lubrication mix.

As far as Winch is concerned, his column is entertaining in a manner that makes me believe he was bitten by a rabid Dingo and it has affected his cerebal functions![sm=rolleyes.gif][sm=rolleyes.gif][sm=rolleyes.gif]

Kreth -> RE: Article about Castor Oil in R/C Report (5/26/2006 12:11:47 AM)

I use castor as lubricant as I have a number of older engines. [8D]



RaceCity -> RE: Article about Castor Oil in R/C Report (5/30/2006 3:52:16 AM)

Kreth...

You have "older engines" BECAUSE you run castor. See my point?

Keep that old iron going....




hpi apollo -> RE: Article about Castor Oil in R/C Report (6/1/2006 2:23:57 AM)

can anyone actually send a link to the article, i am really skeptical about this



loughbd -> RE: Article about Castor Oil in R/C Report (6/1/2006 5:28:49 AM)

skeptical about what????



hpi apollo -> RE: Article about Castor Oil in R/C Report (6/2/2006 5:05:54 PM)

skeptical about that brian winch guy flaming on castor oil and truly getting 44 gallons outta his engine



Sport_Pilot -> RE: Article about Castor Oil in R/C Report (6/2/2006 6:44:27 PM)

I am skeptical that he actually kept track of the fuel he used.

Satsloader -> RE: Article about Castor Oil in R/C Report (6/3/2006 2:20:44 AM)

I'll Paraphrase one of Cher's best lines.. " I'd call him ( Brian ) stupid, but that would be an insult to stupid people".

Ok, that may be harsh on the old duffer, but his reasoning doesn't stand against proven history.. Castor is a superior lubricant for glow fuel engines. Unfortunately a lot of modeler's won't find thier way to info sites like RCU to at least be exposed to alternative opinions. Some will likely take Brian's comments as the last word and find out the hard way what a good insurance policy castor is against the eventual lean run. And that's the real bit isn't it.. I mean, in a perfect world fuel lines don't split, needles don't get clogged, outside temp and humidity don't change. I'd use Klotz synth all day in that world ( and at the end of that perfect world day, I would run the the engine dry and pour some castor in the carb and hand cycle the prop a few times, because hey, even in a perfect world I use nitro in my fuel ). Castor has it's place, even in a perfect world.

I'm just getting back into the hobby after a 30 year layoff. I bought a new Magnum 52 four stroke for my first plane and the break-in instructions is use a minimum of 20% castor, don't use synthectic. 10% max nitro. We live in a hobby deprived area, and the three stores here sell paint balls and car fuel. I finally found a quart of 10% nitro with 17% Caster/synthecic oil. A bit low on Castor so I went down to the local drug store and picked up a 6 oz bottle of Castor oil, the largest I could find. I ask the drugest if it had any additives because I was going to burn it in my model airplane engine. His reply was that it was that it was USP so it was pure and then we got into a half hour discussion about model airplanes and such. I poured an ounce or so into the fuel and shook it up well. No noticable extra smoke, and the engine seemed to run fine. I think I'm going to put another ounce in what is remaining fuel and do my last two break in tanks and first flight using it.

I need to find a source of castor oil locally, the stuff at the drug store is expensive. Around $1.20 an ounce.

Hope the wind is calm in the morning, I may get to test flight my plane.

hpi apollo -> RE: Article about Castor Oil in R/C Report (6/4/2006 2:34:11 AM)

Klotz BeNOL castor oil
$6.79 for 16 ounces, i use this



Phil Heller -> RE: Article about Castor Oil in R/C Report (6/4/2006 5:41:43 AM)

campgems -

You could order from Sig - they sell Bakers AA, also Fox sells a premixed fuel with 20% castor and 10% nitro, or check to see if there is a speed shop (Cars) in your area, they usually sell Castor oil, Nitro, and Methanol, then you could mix your own at about 1/2 the price of premix.

I've got a hobby shop near me that sells some pre-mix, and if I could just doctor it up a bit, I don't think I could top the price, I bought a gal last week for $12.95. I'm not into buying drums of components, which I'm guessing you would have to do to beat the $12.95 a gal price.

I looked at going the internet/mail order route, but you need to buy a case, four gal or 12 quarts at at time. Along with the hazardious materials sur-charge on shipping, the best price I could find was around $20 a gal. As long as I can get near what I want cheep in small quanitys and then doctor it to suit, that is the way I would like to go.

I'm guessing there must be a speed shop around here. We are within a couple miles of the only beach in the state that you can drive on and you should see some of the machines that go out there and on the dunes. That along with the local college crowd and there must be a market for a speed shop. I'll have to take a look Monday.

Thanks for the input. I've still got a lot to learn and re-learn.

Don



Phil Heller -> RE: Article about Castor Oil in R/C Report (6/4/2006 2:17:44 PM)

Most speed shops will sell by the gallon . You have to bring your own container. Is there a club or group of other RC'ers in your area? There must be if you have a place to fly. Check with them.

Good Luck, Phil



Flyboy Dave -> RE: Article about Castor Oil in R/C Report (7/10/2006 7:33:28 AM)

Campgems....

....get the castor cheaper at the motorcycle shop. If he doesn't have it, he
can get it from the "oil man". [;)]

MassiveMods -> RE: Article about Castor Oil in R/C Report (7/10/2006 7:39:44 AM)

The gumming effect of casotr inside your engine frees up with heat , it acts as an excellent protector. And unless you are using a real high tech synthetic you cant go past castor. Synthetics that are avalable in RC are very average oils compared to outside Synthetics, mind you finding a suitable one is real hard and real expensive..



Sport_Pilot -> RE: Article about Castor Oil in R/C Report (7/10/2006 3:35:25 PM)

You can buy castor oil from Fox as well. Morgans will also sell you castor oil. I think about $18 to $20, but give them a phone call, you won't find it on the web sites.



AERORICH -> RE: Article about Castor Oil in R/C Report (7/15/2006 9:03:22 AM)

Hi fellows: I just found this thread while reading a discussion concerning castor oil in glow fuel.
Since I am from the U-Control era having moved into RC some years ago, castor oil fuel is all
that I use then. When getting into RC, my impression of the oil debate was what oil to use in
4 stroke engines. It became my thought that since I had no reason to purchase any 4 stroke
engines, there was no reason to change from Sig 20% all castor fuels. When purchasing an
ASP .75 engine in 1998, there was a slip of paper in the engine manual that suggested adding
3 ounces of castor oil to a gallon of my fuel to extend the life of the engine. Well, the 5% nitro all castor fuel I was using really well oiled this .75 during the break-in run, and all of my other
2 c engines. Now as to the clean up of the plane, I believe we all love to caress our autos when
washing and polishing them, well, isn't it great to caress a model that has safely flown all day
for you? Well, as the weather turned cold, the high oil content and low nitro began to make
my engines to sage somewhat; so, went to 10% nitro 20% castor plus only one more added
ounce of Sig Castor oil. Now I have great flights with a nice smoke trail from the muffler, and
know if some how the engine should run lean it will not be destroyed by the time the plane lands. Everyone has to make their own choice as to the type and oil content they are willing to fly with. In my case, I chose to think my engines are of the old Fox .35 variety, and enjoy
caressing the plane for cleaning when the flying is done. If I ever become the owner of
a 4 stroke, I will follow the mfg's recommendations on fuel and oil type to use.

May you all have great flying with no engine problems.

Rich S.
