In other words, no the DX4R will not make you faster than the DX3R Pro but it will give you mixing for crawling.
+1 agrrement here. the Dx4r is just another channel. Not any more latency that the 3R pro. 5.5ms is all your going to get... Now if you havent set your speed on your 3R pro to 5.5; do that and you'll notice alot faster responce of radio input, to your car reacting.
