The DX3R is the best! The M11 only has one feature the 3R doesn't, ABS, almost useless. The DSM2 , that neither M11 or DX3S have, is a HUGE improvment over ths normal DSM and well worth trading ABS for.
One button programing, superlight weight and ultra fast response time make the DX3R the only choice IMO
