1/10 TC help please.

[revol]

I fancy having a crack at 1/10 TC this year but have a few questions.

Can you use shorty lipo's?
If not, what mah stick pack should I get and how many?

How modern/old of a used car should I start with? AE TC6? Xray t2/3/4? Anything else?
Or, buy a new lower spec car, Schumacher Mi1v2? Xpress Execute XQ1S?
Motors and tyres for racing at MB in Leeds??

Cheers.
