For the life of me I can't remember the name of the book. It was hard bound about 4"x7"... I worked with a guy (I think his last name) Cornfield and he briefly held the record for .049 control line speed and he had a book with the plans/dims to make a tuned pipe for the TD 049. It used an extra TD crank case as the exhaust port for the pipe.

The cylinder fin(s) were machined off the bottom of the cylinder and the cylinder was then inserted through the "extra case" to form a "Rear Exhaust" configuration .049.

If you can picture the the TD .049 in your minds eye, rotate the extra case 90 degrees and insert the cylinder.

If you have the book you'll know what I'm talking about.

I'd appreciate it if I could get the name so I can look for a copy.

Thanks in advance.

Or, you could just get one of these:
