My problems with damaged components has been more insidious. I have one Tx unit that flat spin fell in a nose cone from 3,500' that still seems to work. The lights blink, but compared to my other units, it takes much longer to GPS lock and the RF range is extremely short. At one point the regulator failed and had to be replaced, so something is amiss; and it is still very flaky. Not sure if the problem is the GPS, XBee, both GPS and XBee or something else. Another unit got the duck antenna connector on the XBee bent when I pushed too hard into a nose cone. That one has less range as well compared to my third Tx. Has anyone else seen variations in range among units? I have verified all Tx are operating at the same transmit settings. I am thinking to try replacing the XBee to see if that helps.
the one where the gps takes longer to acquire a lock seems like the gps is bad. That could be causing issues with the voltage regulator. What is the voltage on that board?
The second one seems like a broken etch or solder joint on the antenna trace on the xbee. replacing the xbee should fix that.
