I have been experimenting ............. I set my 18MZ up using 2 x R7008 SB receivers with one receiver set to CH 1 - 8 and the second receiver set to CH 9 -16. All seems to be working fine at the moment. I just wanted to share this with you, I have not tried this set up before.
I have ordered a R7014SB anyway, intended for another model. I will test with this one also ................
Thank you to all who have made contributions to this thread.
Take care all
Andrew
