Recently we discovered some problems with the Spektrum high resolution mode. It turned out, that it is currently not possible to run this mode with two satellites absolutely safe. Depending on unknown circumstances, it can happen, that the radio link is weak, which expresses in yerky running servos, and short dropouts. It appears to happen per bootup, so if the link is ok, it will stay ok, and if it is weak, it will stay weak.
Since this situation is not satisfying for me, i strongly recommend not using the high resolution mode anymore until a solution is available. Probably your setup is not affected, but since we cannot be absolutely sure on this, its safe to not use hires to completely avoid probable problems in the future.
Please go to the "Receiver" Tab at the Setup Screen and choose "Spektrum Satellites (1 or 2)" instead of "Spektrum hires Satellites (1 or 2)". Then redo the transmitter calibration, since the high resolution mode usese different centers and throws. I apologize for any inconvenience.
