the JR Z-1 radio is a helios that has a module compatable with JR's synthesized receivers. I would still get the Helios because it has a better receiver. it is also tested and out on the market for some time. if you get the JR Z-1 you might experience some "first batch bugs."
Thats the exact reason i orderd a M11! I went a whole other direction. I like the M11 so i orderd it. I might cancel my backorder and switch to the 3pk...
