Might be a silly question but....

In the Transmitter selection for the Blade CX2 Transmitter there are different ones with different Expo on them what does this actually mean??

Are there any good sites I could read up on about what these sort of things actually mean and do?

Thanks in advance

Exponential "softens" the servo response around the centre stick position.
So small (possibly accidental) left or right cyclic inputs when you only meant to use forward or back inputs can be covered over by the use of expo.

Imagine a straight line going diagonally up and right from 0% to 100%. This is your cyclic stick input without expo. If you move the stick to 25% along that line, the servo will move 25%.
Now, add some expo, and that line becomes curved so at 25% stick movement, the output to the servo might only be 5% - but the 100% point remains 100% as the expo curve ramps up to catch up with the outer part of the stick movement.
Figures used are just examples...

In Phoenix, there are Tx setups with 25% expo added - this will basically soften the stick response around cyclic centre to make small cyclic inputs have less effect on the helicopter - thus making it a bit easier to fly.

I hope that made sense

That makes sense then thank you for that!!!
