I never used 3 channels anyway. My DX5C has 5... I use 2. lol!I should have gotten a screen protector for mine :/ I'm thinking I might have to rma it though, the power button keeps getting stuck so the radio turns itself on and off.................
I found out something cool about the DX2.0 doing some research on it, the only difference between the DX2.0 and the DX3.0 is a solder joint on the circuit board. You just have to bridge the 2 points together and boom it becomes a DX3.0, it even says DX3.0 on the circuit board lol. I haven't dared to do it though as it is very very tiny like maybe 0.5mm and there are other solder joints within 1-2mm of it and my hands are far too shaky to be trying that.
