I was using a buddy lead with my Hitec A9 as the master and the Eclipse 7 as the slave. I used the recommended momentary switch on the A9 as the trainer switch and the model, with Michelle in control, turned towards the slope and went into a dive.
I released the momentary switch to take control but I had no response and so I ensured that the switch was indeed in the forward position but there was still no response from the stick.
The model ploughed into the ground at high speed with the damage shown in the picture.
I checked that the buddy leads were properly connected to both transmitters and that there was enough charge in the flight and transmitter batteries. So I'm currently bemused as to the cause of the apparent signal loss, which I have not experienced previously with the Hitec AHFSS system.
