Texaco info

Greetings:
New kid on the block.
Have been flying electric but really miss i.c. so I'm back.
Question:
I've read that the Cox Texaco was made to swing a larger prop.
I guess this is to haul a larger air frame.
What did Cox do to modify their engine to make it a Texaco?
Can any of the Cox engines be modified to swing a larger prop?
Thanks, appreciate any information.

Welcome to the forum Scratch Hand Shake

The Texaco engines were made for duration flights, and the low engine speed with a larger prop gave better fuel economy. I think the actual ”horsepower” figure of the Texaco is lower, but it is suitable for large(ish), light and slow models.

The Texaco’s backplate had a smaller intake orifice compared to other ”Bee-type” engines, otherwise it was just like the Golden Bee of the same era. Most Texacos also had a glowhead with more cooling fins as the low rpm with the load of a large prop caused the engine to run a lot warmer.

I think Texaco backplates and glowheads are available at the usual suspects, Ex Model Engines and/or Cox International.

Hope this helps.

Many thanks for your help Kari.
I have two Cox engines that I won at auction.
Both may have been product engines.
One, a Bee type that may have come from a P-40.
The other, a Sure Start that may have come from an AT Texan.
In any case my hope is to build a scale motor glider.
Big but light.
