I was flying at the Club field today surrounded by oilseed rape, which is horrible and impenetrable, a flyer lost his plane in the field and we had a hard time finding it, because the crop makes it impossible to see or move around.
I am using Frsky telemetry which gives RSSI signal strength, it occurred to me before flying I would see if I could locate my plane (in the pits) by putting the transmitter in low power range test mode and looking at the RSSI signal.
Yes it worked and it gave a very directional homing in signal (with the aerial horizontal).
So everyone with RSSI can use this trick to find lost planes in crops and woods.
