I just converted from a DX-18 to a JR XG-14. Extremely happy with the JR and it's XBus system. Hooked up one 7 channel receiver into a Duo X Port and had 14 full channels. I noticed a big difference in response and smoothness over the DX-18. I had several QC issues with a brand new DX-18 and lost confidence in it. The JR Xbus system is great.
