Pretty much everything has been covered in previous posts, but one word of warning on the Blue Thunder Fuel.

I used to use it on several different RCs, and I was having some issues with one way bearings in the pullstart failing constantly and with a build up of "gunk" in the engine, and somewhat lackluster performance. I did a lot of searching and asking questions and it turned out to be the fuel. I guess they Dye they use causes problems for some people. Switched fuel and had all my problems solved.

Not that this will solve your overheating, but just keep it in mind if you have other issues as I described above.
