Cox .15 Special? Empty Cox .15 Special?

Post  HRCBLADE on Sat May 25, 2019 5:25 am

Hi
I am hoping someone could help me with identifying an engine I have. My late father had a huge collection of motors and sadly i have very little knowledge of them or what they actually are. This one has an old instruction sheet and just wanted to be sure it is correct and is actually a Cox .15 Special and not something else.

Many Thanks
S

Just do a Google search type in the name and see what photos show up.


You will soon learn this is a Cox .15 Medallion.  Small Cox Logo

At the risk of being pedantic-there was no such thing as the 'TD .15 Special' ..there was the TD .15, the Cox Special .15 and the Special .15 MkII-in that order of manufacture...mainly due to usage showing the TD .15 was a bit lightly built in the cylinder and failures -cylinder cracking round the exhaust port were appearing in use-Cox's solution was simply-and sensibly to beef up the lower cylinder OD slightly-and thus the Special 15-essentially just a product improved TD 15.The single exhaust schneurle ported Special 15 Mk2 was the result of a lot more R&D and the final development of the TD intended to maintain Cox's competitiveness against threats such as the Super Tigre G15-but fell short with the imposition of the straight FAI fuel requirement ca 1965...

Those three .15 engines are all part of the Tee Dee family. Old Bugger
On the Cox manual the word TEE Dee was left out on the last two versions.
Primarily anodizing color scheme, pistons and cylinders are the differences as described:
