Spektrum RC DX4R Pro 4 Channel DSMR Racing System w/SR2000 & SR410 Receivers
I've owned this transmitter for a year now. I am very satisfied with its performance. Fast, smooth, excellent setup options and model organization. I did immediately put on the thickest grip to add more weight to the system as it feel ridiculously light when you first pick it up. I was also initially concerned before buying it due to how it is completely plastic and can look and feel cheap before you actually use it. Ultimately it has been a delight to use, with really no problems at all. The spektrum receivers work well and consistently, no connection problems. I might upgrade to the fancy new one, but this one has been very good to me over the past year.
