I've been meaning to ask this question for a long time - it's a 2-parter.

First of all, I've seen several references to a "Texaco" event, apparently for 1/2A FF. It appears to have something to do with duration, but I'm not sure (I've seen specially built Cox engines with what appear to be oversize tanks).

Could someone please tell me the principle behind Texaco (and perhaps a few interesting web links as well??)

Also, why is it called Texaco? Did Texaco Oil used to sponsor it??

Thanks a lot for the info,

Bob

Yes, the event was once sponsored by the oil company.

Here are the official rules. There are several different Free Flight and R/C Assist Texaco events. They are listed under the "Special Events" headings:

For more information check the SAM web sight and specifically the rules book. Also check the COX FAQ at the top of the forum. I've included information that I had to learn the hard way. Basically the event (it's a contest) requires a wing loading of 8 oz. per sq. foot of wing (I believe this is a projected wing area) and a 5.1 cc fuel tank (baby bee size tank). Flying is very gentle. You may used an old timer or and early scale model for the event.

Just because a Korda Wakefield is Cub Yellow it's not really a scale Piper Cub.

OK, fess up...How many remember the TEXACO TV commercial line, "Trust your car to the man with the Star"?

PS There are lots of Texaco construction articles in old FM issues.

Some fly these 1/2A engines with 7" or even 8" props. My first Cox Texaco engine was the 1998 version. It had a large unvented (red aluminum) tank with reduced size intake for better fuel draw at low RPM, a plastic backplate with one fill nipple and a small vent hole, and a glow head with extra cooling fins. It came with the older spring starter that completely disengages.

Yup, I used to 'trust my car'. Hey, can anyone remember Tydol?? That goes back even further.

Good for Texaco for sponsoring it.

So, I take it that this is a duration event? Like, how long you can fly with the motor constantly running?

Is throttle allowed? I just took a look at the rules... Interesting challenge...

Is it really all that popular?

N1EDM:

It's a duration event, run as long as you can with the fuel allowed, usually fifteen minutes.

No the engines are not throttled ( in the case of 1/2A) but... You can alter RPM with the muffler or with the venturii, though they are fixed.

Skelly Oil marketed the Jimmie Allen line of rubber powered models in the 1930s.

SAM still has Jimmy Allen contest events.

FWIW, I think outside the USA they also run a Texaco event for .09's. I believe PAW makes/made a diesel that was especially timed and ported for large, slow turning props.

Yes they do and I think they still fly class A texico in the USA. I once prepped a Mills 1.3 diesel for it. I was turning a 12-4 prop at 4K (this with a Perfect #4 tank, 1/2 oz.) It ran for a while, gotta pack a lunch.

I have the article somewhere about how Norm Rosenstock and Dave Platt got "A" Texaco started years ago. I got to meet both of these legends last year at the VRCS meet that Bob H hosts near Apex, NC. That event is coming up in a bout a month and it is definitely worth attending. I know I'll be there.

Bob H in the tan hat, Platt in the white hat.
