Yes, it is implemented with v6.08
You can do wireless student/trainer mode by using a TINY5 at the trainer BAT6x. It must be bound to the student BAT6x, set to sum signal output (12ch). The sum signal output of the TINY5 is then connected to the PPM input of the trainer TX. The TINY can be also powered via USB from trainer BAT6x USB port; no extra power supply required.
