How to tell a v1 10ch expander from a v2 ?

Purchased a used setup that has a 6 ch nano rx and a 10 channel expander. Two questions.The transmitter in use is a converted Kraft 5 ch single stick,What does the 10 channel expander do for me that the nano rx doesn't?I am just using standard analog servos at present.
How can I tell what version expander I have?

The X10+ v1 has a single serial input at the top and 11 sets of pins on the opposite side. The x10+ v2 has dual serial inputs next to each other at the top and 10 sets of pins on the opposite side.

The X10+ gives you the ability to use receivers that output serial data streams, and properly power your servos and receiver.

Do I really need to use this with a nano rx and analog servos ?

That really depends on the application. Just because you are using analog servos doesn't mean you aren't pulling the same amount of current as a digital servo. A digital servo can react faster, but they are both still "analog" in nature because they both use a pot to determine position of the output shaft (with exception of the new servos that use optical encoders).

What are you flying? What is the power source? Are you using a switch between the battery and the receiver?

With 2.4GHz the number one important thing it power! Our receivers operate down to 1.8 volts, which really helps, but you still need to be using proper power.

A Nano will work, but you need to make sure that any moving wires are located more than 2" away from the antenna wires. We use to fly our turbine jet aircraft with just Nano receivers, but moved to the X10+ and Nano (or RFU) to move the receiver away from the wiring.
