Cox TD .15
I'm looking for burned out TD .15 plugs, preferably the high compression type. I have a TD .15 in parts to which I'll be adding a throttle and muffler. I have a low compression plug/head but this is likely to burn out someday and while it'll be easy to make that one a turbo conversion, I'm still curious to see how well a high compression head would work.
I'd like to make up a fully throttling, muffled version like my TD .09

Andy, a local hobby shop has quite a collection of hard-to-find cox parts. I will go and have a look tomorrow. PM me your address and i will send it out-- given i can get it.

RE: Cox TD .15
CP,
It's a Canon with 3.4 megapixels and a macro feature. But why this picture displayed so large is a mystery to me. Happens now and again for no reason. The original .15 had a ball and socket but a deluxe version had a conventional wrist pin. This is illustrated on Martin Hepperle's site.
Redbird,
I appreciate that. I'll inbox you shortly.
Skaliwag,
Just so there's no confusion, what is pictured is a TD .09. In the .09 pictured, the throttle is from MVVS from their .09 and the muffler is custom made. However, the muffler header IS off of Cox's RC .09 of a few years ago. I never owned the engine itself, I already had two TD .09s so there was no point. I didn't like the weight of their .09 muffler so I made up what you see.
For the .15, I got the crankcase, crank and all the bits excluding the piston,cylinder and head from a hobby shop in Toronto when I spent half the summer there. They had the one Medallion .15 but also a half dozen Medallion .09 crankcase and crank etc. Can't imagine why Cox would package such a set up but there they were. This was a large, established shop that had bought out the inventory of another shop that had gone out of business.
It's a Medallion .15 but I can grind out the crank's port to look like a TD and the plastic, front housing will be modified to take a throttle, probably off of a Norvel .15. I have a BLANK cylinder and a piston on the way. Reason is, I want to make up a cylinder with one exhaust port and three by passes. Also I'll orient the exhaust to the one side as per most engines.
A few years ago, Raj from Singapore sent me a TD .15 to throttle and I did but it wouldn't hold an idle less than half throttle. I've learned a lot since then and I think I can get the .15 to throttle well.
What this is meant to find out is if the Cox design can compete with today's engines. I think it can, easily, and this a real testament to the genius of Bill Atwood and Roy Cox. Their design, the entire Cox line STILL has a modern, attractive look.
