booster set question

[sharpshooter]

I've broke my supra and I was planning to get another one but now i'm interested in the booster sets, i've read almost all the booster threads and I still don't understand.

correct me if i'm wrong but to my understanding, if I have one with a 2.6, and i'm on 'B' mode, I drive my car around with it being slower than a standard car with a 2.6, then I hit the 'boost' button (like the NOS button in the fast and the furious) and it makes the 2.6 go faster than a standard car with a 2.6. am I right?

And how long does the boost effect last? is it only effective if I hold down the boost button or something? I find this useful for turning in tracks etc.

so A is to control regular cars? and B is for what I described above, and C is for a constant boost speed?

and I understand it is a 4 channel controller, so does this mean theres a seperate thing for adjusting the frequency? like if I buy the 45 mhz booster car, do I just adjust it for 45 mhz THEN fumble with the ABC thing?

sorry for all these questions, but this is really fustrating me, please reply quick, I have made plans with my friend to go get our cars and stuff tomorrow!

thanks!!!
