XRAY - Model racing cars

Hello,

im thinking of buying the m18mt, but i dont know if i should take the powerpack or not, because it seems the cheapest thing to do to make it fully RTR, however i dont know how it'll do on the long run, if i wanted to get a faster motor for example. So my question's are:
- What is the limit of turns of the ESC
- Howfast is it stock [m18mt with powerpack and 1100 MAH battery].
- Are there many motors for it or do i have to go Brushless to go faster?
- Is there a conversion to do a 1/10 motor in it [540 size i believe].
- And are there ways to put other battery packs in them with a higher capicity then 1100 MAH?
- Why should i take the M18MT and not some other 1/18th car? (what makes it good or bad?]

If you got any other recomendations about the ESC, motor or anything else, please post them [and where i can get them in the netherlands, or a Online Shop!]

There are the questions that i wanted to ask, i dont know if these are asked before but i couldnt find it with the search function.

thanks alot, i've allso seen a cheap brushless set, would the xray be able to handle it without being ripped apart? [im going to buy a alu shaft anyway, but the rest stock probs.].

Its a 5 Tunrs brushless set

sorry for this post, i've read the FAQ, never mind
