Here is my configuration:
Transmiter: Futaba 18SZ
Powerbox: Competition SRS
Receivers: R7003SB & R7008SB
Airplane: Carden Pro 124
At my normal flying field I usually get those values:
Antenna Fades: between 20 and 75 on each receiver. Sometime I get a little bit over 100 when there is many flyers.
Lost Frames: Most part of the time it's 0
On a specific flying field I got those values last weekend:
Antenna Fades: Receiver 1: 1590 and Receiver 2: 940
Lost Frames: 255
At what values do I need to consider grounding my plane.
