None other than we are all volunteer and use our personal equipment and my pockets aren't that deep. We actually have a grant in place for a matric 210 but covid19 has kept the EMS director busy and the program got put on the back burner. I've unofficially used my fpv drones in the past for search missions but the limited flight times and analog camera make them pretty worthless. I bought this one just to get the ball rolling for establishing a program. The radio is more of an experiment. I think I will end up shaving the weight more, replacing the antenna with a thin wire soldered directly to the board, or replacing it with a family radio, packaging it with some form of protection and purchasing a drop mechanism when they come available. I don't believe I will able to ever get it loud enough to be heard over the props. Yesterday would have been an ideal example as we had a river rescue where a raft overturned and a guy was stranded for several hours until we could get to him. It would have been nice to at least let him know an ETA and ask how he was holding up. Yes, I replaced the 1800mah stock battery with a 2s 450mah I had laying around. The back frame is metal and really can go too if I decide to continue to use this one.
