Not objecting to obtaining DLA system, but not worth investment just for evaluation.
According to the spec the raw average bandwidth of the data stream is 97b / 0.08s = 1213 bytes per second, (i.e. about 12000 bauds). Basically any datalink that can handle sustained unidirectional transfer at that rate would do. For short distances the bluetooth/serial modules like HC05 or HC06 should work just fine.
If you'd extract the roll/pitch/yaw from the packets by using a microcontroller and transmit only them (with some header/trailer bytes) you can do with maybe 1/10th of the bandwidth
