Nearly lost the sbach today due to loosing rx signal. Coming down in a steep dive lost all control and couldn't pull up. Got closer and closer to the ground and finally got control back about 10m from the deck. Needless to say I landed pretty quickly after that.
I was extremely lucky in the end to save her. Thinking back I must have lost signal momentarily earlier in the flight but at the time I thought it must have been a wind gust.
I was using my spectrum dx6i and and orange 6ch with orange satellite rx. I've had problems in the past losing signal with the 6ch orange rx but thought the addition of a satellite would tidy that up. How wrong I was, I've heard that the 7ch fail safe orange rx is much better quality but who knows. I think I might just take the official spectrum rx out of one of my other less important models and use that and replace it with the 7ch orange rx.
All I can say though is I'm one lucky guy.
