armchair engineering here but looking at the canopy lines and gear doors etc.. i have a feeling the rcs isnt going to be that small
More so than that.. the engine setup is REALLY bad for RCS. There's nothing low-observable about those engine nacelles at all. RCS will be bad, as will IR detection.
Biggest RCS problem that airplane is going to have is head-on looking into the intakes. The engine compressor blades are going to show up like the side of a barn! There's a reason those are shielded from direct view on the F-22 and F-35.
