Micro t questions

[nckmat]

Hi,

Just wondering if anybody knows with a box stock Micro-T:

What size is the stock spur that comes with the car?
Can you gear the stock motor down beyond what comes in the box?
What is the stock FDR?
Can you gear the Atomic BB motor any further than the stock motor?
Do you have to change radio system or servo if you upgrade to brushless?

Don't seem to be able to find answers anywhere.

Cheers,

Nick
