Crawler guy chiming in here. I started with a dx3e worked great but I needed a better controller for more than one rig. I then purchased a dx3-c. It was a great radio for a while, not one problem not one glitch. I love the feel of the spectrums. Then I needed more channel mixing to run dual esc, so purchased the 4pl. The 4pl is amazing for the price but I still like the feel of the spectrums better. If I could get away with fewer options I would go back to the dx3c. I never had any problems with them even when I was using 333-486 in/oz servos. Of course I always used an external bec or a crawler esc with a beefy internal one.
