yeah the wildcat eliminator is actually a great race fuel ive been running the 30% in my jp racing .21 p5 and no problems at all. engine runs good temps. stays in tune, not a whole mess of residue left over like you end up with when you run blue thunder(garbage). before i was a hardcore odonnell guy but im leaning toward the wildcat now. everyone else i race with all run and swear by byrons,one of them is sponsored by them and loves and raves about it.so stick with the good big names is what i say and stay away from the blue thunder if possible. haha
