Oh awesome. Thats the fuel I'm trying to get shipping quotes on. I understand that Sig has been around for a long time in this hobby and I am under the impression it's a name I can trust. How about Morgan Cool power or Pro Pattern? Have you experience with those blends by Morgan rc fuels?

What size/ format is best to use when posting pics here, and what is the best way to view them? When I open pics I only get a vertical strip portion of the image and the rest is not showing. Is there a recommended browser or something? What am I doing wrong?

Can I get your recommendations for the best fuel to use in the Big Mig 074 R/C? If I remember correctly the instructions state that "20% nitro/18% oil" is recommended but I'd like to hear other peoples opinions.

Hi guys. I bought my first Norvel engine and it arrived today. I also ordered a turbo plug head to go with it as I was informed this was the best combination for the Big Mig 074 RC. I had both heads off and on the table and am now confused as which one is which. I posted a pic. Can someone help to figure out what one is what? I'm not talking about the threaded plug insert or stock button plug. I'm talking about the cylinder head (part with the fins). I've been going through Google looking at images but am coming up short. All help is really appreciated.
