Hello all. I am very curious about the above, of course. Who are your most reliable suppliers of aftermarket upgrades? What upgrades do you consider essential, and what do you consider must-avoids? Also, as far as a signal booster, I am looking for something to avoid problems passing behind trees and houses if possible. I do not see me flying miles and miles away, but I certainly want great signal when in the vicinity, and being able to transcieve through a house to the backside of the home would be GREAT! Thanks.
