Mike the module still fails to flash the firmware and will not bind any Receivers, it will however power off when you select a model that uses the internal module. When the flash fails it would appear to not upset the multi module as it continue to work in my X7.

Edit: Even when I bound a Rx to the multi module on my X7 and I then transferred the module to the X10S it failed to work.
