Texaco engine question

WoodCutter Tue Dec 27, 2011 10:41 am

Hello All, I just registered today (1st post)

After 35 years of modeling, I had gotten busy with other things and not built flown for a few years. Well I'm back now and am real exited about getting into the 1/2 A end of the model spectrum.

I have just ordered some of the parts for a Texaco engine. Before I get the tank and Backplate parts, I have a question about an apparent contradiction....

I was reading the rules for the 1/2 A Texaco event on the S.A.M. website. It said that the engine tank size must be less than 5cc's in capacity. Why then is cox selling a tank labled as Texaco 2 which is the larger 8cc size?

I would like to be able to have a goal of competing in the S.A.M. events one day so should I get the 5 cc size or the 8cc size?

Thanks for any replies.

Robert

Cox made two Texaco engines. One with 8cc tank and other was smaller and belive under 5cc. Spaecial tank was made for this engine.

Hi Robert(good name),

I don't know much about FF or Texaco for that matter, but I found this in the SAM contest rules.

E. 1/2 A Texaco engines must be Cox reed valve .049's with an integral fuel tank of not over 5.1 cc capacity. These must be basically "stock" engines as typified by the Texaco Jr., or Babe Bee designs. Other Cox reed valve engines such as the Black Widow, or Golden Bee designs are acceptable as long as the larger 8cc tanks are replaced by the 5.1 cc tank, such as found in Cox #1596 conversion kit, containing the smaller tank assembly. The only modifications allowed are: Moving the fuel pickup from the middle to the bottom of the tank, addition of a muffler, and/or addition of a needle valve extension.

I found it here> http://www.napanet.net/~billb/Contest_rules_1997-98.htm Scroll about half way down to "engine definitions".
Sounds like the standard BabeBee tank would be ok by the rules, but like I said, I don't know.
The Texaco Jr. tank does look smaller than the BabeBee one to me sometimes. I only own one of the
8cc ones, but plenty of BabeBees.
I'm sure someone else will chime in.

Hope this helps and doesn't confuse you more.

Welcome to the forum Robert.
As mentioned above cox sold the 8cc texaco and 5cc texaco jr.

WoodCutter Tue Dec 27, 2011 11:33 pm

Thanks for the replies....

It's interesting that Cox originally sold both the 8 and 5 cc tank Texaco engines. I would think that the present owners would consider assembling a Texaco version with the 5cc tanks. I can understand someone wanting to fly a 8 cc version for "sport" use with the large diameter prop, but personally if I'm going to build a Texaco event-legal airplane I'd rather put a event-legal size tank on it.

I just sent off for the parts today to do just that but it would be nice if one day a person could buy the small tank version without having to buy the extra tank.

I shouldn't complain though, I'm just happy that someone is finally trying to support Cox brand product in a better way again.

I just hope that I don't find out the hard way that Cox engines might be just like potato chips.... you can't have just one, or three! Smile

The thing you don't wanna find out.
yeah you will end up with loads of the things!
Put the idea to Matt or Bernie as they are both members here they might be able to help you.

Hey Woodcutter!

Yep! What Indra Said!!!! These things have a way of working their numbers into your engine collection!

Also, I think it'd be very interesting if you were to post your progress in the Texaco Event! Contest summaries are usually very brief, with flat numbers of the results. It would be great reading if you were to post an account of working up your engine, and the things that happen along the way.

Just a thought. As you might suspect by now, members of this forum love all aspects of running and/or flying Mr. Cox's little engines!

Kim, Yeah that would be great if people were to describe their Texaco Event experiences more. I'm just in the planning phase of trying it out myself. I've yet to start building an old timer model for it. However I'll try and remember to post when I get further along.

Frankly, I'm surprised I haven't been able to find more online about building and flying in the 1/2 A Texaco event...

With the "Golden Age" of modeling from which the aircraft used must be from being from a time when many of us weren't even born yet, you would think that getting the word out about the fun to younger people would be a high priority. Huh...

I can think of litterly dozens of things I'd like to know about the Texaco event and the kinds of planes that do well in them. I plan and joining the Society of Antique Modellers (S.A.M.) real soon here. Maybe their newsletter will be helpful.

Have fun now you'all

Woodcutter,

We do have a Texaco Jr. Look-alike with the 5cc tank. Here is a link to it:

Yeah that would be cool.
Maybe a summer build off?

lol only if you are getting 20 min texaco flights lol.
It no scary if you trim and build well.

Welcome to the Mad House, Woodcutter! Oh, you WILL be bitten by the dreaded Cox Bug, it happened to me! What?

Where are you in the World? I see no location in your profile

Yup it happened to all of our members lol.

WoodCutter Thu Dec 29, 2011 10:33 am

Bernie, thanks for the link to the "Black Sportster" I had skipped over that one because of the lack of a extra cooling head. I didn't know it came with the Texaco Venturi backplate. I did read somewhere that the standard glow head works O.K. even for bigger props, but I'd still probably replace it with the 5 fin head for extra piece of mind.

Regarding the Texaco airplanes themselves, I'm a bit confused here... I thought that the event was flown with old timer models but with rudder and elevator R/C control. Is it only done as Free Flight?

That idea dosn't give me the warm and fuzzy feeling either.

I think more research is in order....

Robert,

Many modellers replace the standard glow head with this one for low RPM applications:

http://coxengines.ca/product.php?productid=450&cat=27&page=1

or this one for high RPM applications:

http://coxengines.ca/product.php?productid=452&cat=13&page=1

the difference lying in the "heat factor" of the insert.

There is some discussion as to whether the 5-fin head conversion is indeed "Texaco legal". Mostly, judges have been fine with them but we have one customer that got such spectacular results (using our head conversion), far surpassing other competitors, that this induced the ire of some competitors, and he was disqualified.

He has since launched an initiative to get our heads officiallly declared legal with the argument that OEM Cox heads are nigh impossible to obtain.
