I was going to say, the top one is a diesel and the bottom one isn't. But Dan stole my thunder.

Danny has one of those Cox engines with a disc valve. At one time they brought near 200 on eBay. Down on power next to a TD. At least his was. I think one of his hot reed valve Coxs ran as fast.

I have two of those RR-1's.  Were used on Combat Kittens and both out ran Tee Dees on bladder.  I only ran 10% nitro in them.  Also have the reverse disc valve in them.   Oh, the props I used were top Flite 6 X 3 nylon. D>K

The diesel is Russian and was sold by Mecoa quite awhile ago. It was $39.95. I bought one and had it for a few years. The castings were nice but the back plate had no way of being fastened to the case. They presumed that tight mounting to the firewall would do the deed.
I got rid of it a few years ago. However I have reached the age when my memory for names is almost a permanent state of affairs. Sorry I don't remember the name it sold under. I never made any attempt to run it.

Hi Bob,  The diesel is a Russian or Ukraine .080cc 1/2A Combat engine. I've got one but haven't
run it. I bought it 15-20 years ago. I was going to see how it ran compared to Combat prepped
.049 TD's.  That was about the time that the new generation Russian/Ukraine/C.S. .049 engines
killed Cox TD Combat.

Hi, Gents.
Thanks for all the interesting replies.
I may play with the little Diesel as it looks kind of neat.
The Cox engine will go to the Brodak museum since I don't do much with 1/2 A.
