Are any of you going 2.4?
I bought a 12Z 13 months ago just for my YA F-15 and future jets. I'm going 2.4 but not Futaba's expensive peice. Xtreme Power Systems has modules for both JR and Futaba--I'm just waiting for them to release the 12-chn module for the 12Z. It is already completed according to them, just waiting on the plastic housings.
Many folks at my field have been using them for a while--check them out:
