XRAY - Model racing cars

Hi guys,

A few noob questions. I'm planning on getting the new NT1 limited edition with the JR HV servos.

I was wondering if someone could help me with the following questions:

1) What size/capacity LiPo do I need to get that will fit the NT1?

This? http://www.amainhobbies.com/product_inf ... ancer-Plug

or this? http://www.amainhobbies.com/product_inf ... ancer-Plug

2) Is the receiver that comes with Spektrum DX3R capable of handling a 2S LiPo (8.4V)?

3) Do you recommend both servos to be high speed? Or should I get the high torque for steering? JR Z9100HVS and Z9100HVT?

4) Does the kit come with an air filter for the engine?

Thanks so much,
G
