As I mentioned before, I would post an update regarding the low cost
XRX traffic system that does direction. www.zaonflight.com

I got one of the first pre-production systems and it works well. I
helped beta test it, and consider this a real asset. However you do
have to pay attention to the type of aircraft you fly in order to set
it up correctly.

I know they are taking orders for it now. If anyone wants to more, I
think I know enough to help now.
