Hi it looks like you have got a clone if it have a white sticker on the side saying Tear invalid and patent pending with the number FCCID: BRWDASRX11. also inside the casing the number HC809E with mine when you first the bind its ok, both units switch on ok then when you disconect the battery and trany
Restart trany connect battery and i find the main receiver lights up but the satellite receiver will not switch on, no light. If you rebind it switches on i can only assume that only the main receiver is working
only,
This may work on a range test but at a distance with the plane at multiple angles can the receiver recover the signal, how can we check this. john
