fuel is like 10% oil. 20%nitro, 70% fill. If you can generate 15% more power out of the same amount of fuel then your going to have better run times. I'm not familiar with the engine, but there should be a thread on it some where. Basicly, to power the buggy enough to reach the end of a straight the 30% will use less then the 20%.

In terms of weight, i think the Mbx5 is not that much better than the Hyper 7. If you have some money to burn, may be you can buy the good 2.4G radio system...B/c you can always pull it back out and tranfer to another buggy.

Engine, the 21BF is good; but for about similar price, I will also look into a 3 port RB, i think its called "S3". RB is much better in terms of power and longetivity, and i like the way it sounds too. I also ran the Mamba .21; not as good as S3 or 21BF...

I think the weight thing is overrated . I just bought a cen matrix fre & everyone was saying it's heavy. I weighed it next to my friends losi & it's only 7 ozs. more. I don't know about you but i don't have pro driving skills so i can't tell a 7 oz difference. Get better on the hyper 7, you'll know when the buggy is holding you back.

Heat it with a heat gun, or a hair dryer, then unscrew the head bolts while its still hot
nothing to see here................................
