RE: -=OFFICIAL HPI FIRESTORM THREAD=-
try their race 2000 blend, stay away from the rtr blends, too much oil....I had to use wildcat 20% rtr blend with 18% oil and my motors all ran funny, I mean I was ready to smash a truck cause I couldn't get a good tune with all that oil, I only bought it cause the hobby shops fuel delivery was several days late and they had been bought out of fuel, big race weekend....I purchased trinity monster horsepower 30% with 12% oil and I really like, gives a great tune and I have stuck with it, use it everywhere...
give a quart of Byron Race 2000 a try and see how you like it, then you aren't out much, but do try a medium plug, with all my nitro experience I have a personal preference of McCoy glow plugs, also Dynamite plugs are McCoy
MC8 is Medium/Cold
MC9 is Cold
MC59 is Hot
I wont buy a os plug unless I have to, they don't last as long as McCoy
The traxxas #3232 plug is a good long lasting plug too
