I did a factory reset on the Mercury and I had removed the old RX bound to the CORE for this model before I did any reset on the Mercury. I tried to bind two 26D RX. Both flashed fast red and I could bind RX 2 but RX 1 gave me a message that said to switch on the RX. I disconnected that RX and when I plugged it back in I could bind it and see both on the CORE.
I set up all the channels on the Mercury and noticed on the display it only showed RX2 as “OK” and blank for RX1. The CORE shows both RX bound and both show Unique serial numbers and LQI values. If I unplug the RX2 the Mercury goes into failsafe. Even though RX1 is plugged in and shows an RQI on the CORE
I will be at the flying field tomorrow and have a second Mercury that is also new and 2 new 26D and some new cables. I will try a new RX 1st.
Your advice is appreciated.
