Depends on what kind of tracking you're looking to do and how much your house payment is. I got a GPS tracker with a SIM card for around $100 which let me call the thing, then it texted back its location... there's telemetrum's products if you have a HAM --also BRB, Eggfinder, Missile Works, or you could attach a large streamer to track visually. Hills and valleys may play havoc with your radio transmission... I'd be asking people you fly with what they use with good results...
Later!
