The FWTM Lite trainer module is an alternative option for pilots who do not have the radio with the PARA trainer system but still expect to use the trainer system remotely. Power the trainer module by attaching it to the radio module bay, now the student radio can bind the trainer module in ACCST or ACCESS mode and work at low latency, so a simple wireless trainer system build is completed very quickly. By plugging an Audio type trainer cable into the trainer module, this module system also provides a wired way to create connections between master and student radios.
