That R7018SB receiver is looking nice. I will get one of those and give it a spin.
View attachment 19825 This reciever will be nice....very similar to the Spec/JR power safe rxs. I'm sure it'll have a soft switch connection so you wont have to mess with running your power leads through conventional switches. Forget the power board/expander etc. Cant wait till Futaba officially releases it and lists it's full capability. They'll probably publicly announce it and the new 18SZ at the same time...
I'm not sure they'll replace the 18MZ any time soon. Their top end radios seem to have a pretty long shelf life. The 9Z was very long lived and the 14MZ went 7 or 8 years. The 18MZ is only 3 years old.
If this is near what it looks to be I have to think it will put a dent in 18MZ sales, but that will remain to be seen. I know that the 18MZ out sold even their most optimisitic projections, so I'm not sure that will bother them much.
