So far after one year the iFly 720 works great. What a powerful punch for the price. I recently installed a Trio Pro Pilot and on the first flight eveything worked flawlessly. The A/P displayed and tracked all the waypoints. Toward the end of this first one hour flight the A/P displayed "No GPS." NMEA Output indicates "No serial port detected." Connected devices / serial ports have been reset to default. No change.
