I just got a DX3R I was messing with it today a bit and it is a lot more user friendly than my M11 . I have a M11 fhss and if the M11x is the same as far as adjustments it's kind of a pain to operate . The DX3R seems much more easy to navigate . I haven't had a chance to use it on the track yet , but I have used my friends and I liked it a lot .
