My typo on DX3.0 vs. DX3R. Still seems like an esc issue to me. Perhaps try profile #5 I think it is, the one with 25% reverse just to see what happens? Apologies if I'm off base, but are you sure you are switching profiles and not something else? I know the blinky lights and their color confuse me the way I have mine partially blocked by the chassis, have heard of others with same issue. Do trims seem to make any difference?

Help guys!
