The 7700kv on paper is between the 4.5 and 5.5, I ran the 7700 all last year. On the track it runs with a good 4.5 when geared right. Both my Mamba max's have tremendous mid-band HP witch makes them unpredictable in TC's as stated by rcenut123. I run my low end up and it helps smooth out the mid-band. My 7700 will pull away from the 3.5's and 4.5's coming onto a strait but the 3.5's will pass me on the long straits.
