RadioActive
Payload weight options are quite limited with the Phantom.... in any case..... I have used a DJI LK900Mhz datalink system which has a side benefit of a complete flight trace on my Notebook PC to the final landing spot c/w GPS location. weighs less than an IPhone but costs a lot more...... Don't recall though if it will work with NAZA V2 though as it requires canbus etc. Radio direction tracking without GPS is possible with many frequencies by means of a directional antenna such as a patch or Yagi antenna of the appropriate freq design. If the MR can't be found because the radio signal is too strong.... a 5 to 15 dB attenuator can be put in line between receiver and the antenna to get better direction as you get closer to the MR.
