Thank You.The E50 can use SD cards up to 128GB (<=32GB use FAT32 formatting and >-64GB use exFAT formatting)
The ST16S can only use <=32GB with FAT32
Figured there must be a reason for the SLOT being there! The manual has very little information about using the SD Card in either the Camera or the Transmitter.For what do you need a SD card in the ST16? There are several statements not to have a SD card in during flight. I do not know why but who knows ... bad experiences or so. However I do not understand the use case for the SD card in the RC except the one in the ST10 as the only public file system.
