Hi Shane:
Thanks. If we were not selling the plane, I might buy the EX. But now that I've learned it started out at $700, there's no way this cheap b is going to spend $1200. I would wait for the economy to tank more and for the price to go back down some. Besides, we have PCAS in the plane so we "see" other Mode A/C aircraft.
Any specific place you bought your aluminum box for the Pi? (Like, it was it designed specifically for the Pi? ) If so, link please? Or just a generic electronics box?
