It feels a lot lighter than my other futaba radios. But in fairness to futaba, the DX is built as "robust" as their radios. You can certainly feel the "plastic" in the Spektrum, not that that will make it function any worse, it just feels "lighter"
Also, being a tray radio, you will need a harness to support it. It's way to wide to hold and operate a model easily. ( but I kinda guessed that before ) so ordered a nice graupner body harness for it... don't I look special now
