I just picked up one of these Cox Texaco .049 engines at a hobby shop.  Yes, it is brand new, in the packaging and all.

My questions:  is the Texaco engine just a standard Cox .049 with a large tank?  I've read that the glow plug with its extra fin is to allow the engine to run cooler and thus swing a larger prop.  Can I use a standard Cox glow plug and a standard 5 or 6 inch prop on this engine?  As far as power or rpms, is the Texaco comparable to a Babe Bee or to a Black Widow?

Bottom line is yes. It will not hurt the engine...but as Larry said, less power.

The smaller venturi provides better fuel draw at lower RPM's, and the glow plug dissipates heat better because of the extra cooling fins.

Not a bad idea, Larry!  I think the only use I would have for the Texaco engine is to use it to tow a 2 meter glider.  The long run time would fit well with this use, but then again, a black widow will run long enough to get the glider to a good height.

I'm not one to modify any engines, as I'm afraid I would screw things up!

Anyone got a mint condition Black Widow that they want to trade for a new, unused, untouched by human hands, Cox Texaco .049 engine?
