I have tried nearly all fuels with a 30% nitro content. The exception to everything listed would be the Traxxas, I never tried it. For the most part, they are similiar, but not the same. Wildcat is made here in KY. One of the stores here sells almost exclusive Wildcat. Also Wildcat theoretically makes Trinity Monster HP. I can tell you that all I run is Trinity Monster HP 30%, nothing else. It will make a huge difference in HP on some engines like Pico, and moderate gains on other engines. I can also say that Wildcat is on the very bottom of my list. Maybe I had a bad batch, I don't really know, but I actually threw out 1/2 gallon of it. My engines are easier to tune with this fuel. O'Donnell is what all my Serpent buddies swore on, I tried it, and it is a good fuel, just not as good as Trinity Monster HP IMHO. BTW, I also buy it by the case (price break), if that's any indication of how much fuel I go through, and have 7 gallons or so right now.

I was listing high dollar fuels, and demand maximum power out of what I have. If you are new and just playing around, any of the fuels should work for you, so get whatever is cheapest at your LHS. I would avoid a real high oil content though. It can cause problems. I also prefer synthetic or synthetic blend, as too much castrol can build up. Ultimately the choice is yours, and there are a lot of good opinions in here.
