None of the searches seems to address this problem. This is a virtually new I2 with < 10 hours of flight time, that will not power up. Last flight likely a month ago, all was well. Using three different sets of paired TB50's, all fully charged, will bird will not power on with any set. Only anomaly I can see looking at the battery compartments are two slide type switches where one is free-floating, that is, no detent nor spring load, the opposite one the switch is spring loaded in a fixed position. This in itself seems odd. There have been no issues with this Inspire.
