I would expect it will work fine. I have the RTx system which uses the same GPS and radio and I've flown to 21k with no loss of signal and recovered up to 1 mile away with no issues. I fly my RTx simultaneously connected to the LCD screen and to my phone (using RocketTrack when I have phone signal). Please report back here after you've flown and share your experience.

I finally got to do this launch. When I lost sight of the rocket and looked at my phone, RocketTrack was updating the position and altitude. GPS said the apogee was 17,455 feet. The Stratologger CF altimeter reported 16,380 feet, and I think that may be more accurate.
I turned off Follow Me and zoomed out. I could see where the rocket was over our field. Its path was traced with a thin black line. I got regular updates on altitude and coyld tell it was descending under drogue. The distance was updating too and i could see it was drifting over a mile away.
I was able to tell about where it was and pointed in its direction. Mikec searched with his binoculars and found it right as I was saying "700 feet, main should be firing." And was able to confirm the main was out.
It landed 1.5 miles away, so we took a Jeep out for retrieval. The data stayed on my phone and i could see the distance to the rocket counting down. The driver is aggressive and we took a hard, slamming bounce that knocked the phone and receiver out of my hands. When I picked them back up, the bluetooth had lost connection with my phone. I got them reconnected but all the data was gone. According to the screen before the phone got knocked out of my hand, we were within 1300 feet. I got out of the jeep and walked around for a few minutes before I reacquired the signal and it took me to my rocket.
So it worked to at least mid 16k feet, mach 1.5 and a mile and a half out. I really liked watching the trace on the map and the stats update. I didn't like losing the bluetooth connection and data.
