The Absima CR3P is made by FlySky, it is basically a modified FlySky GT3B/GT3C.
There are a TONNE of issues with FlySky and interference. They have been known to interfere with one another and with other radios too, specially when running on 8 batteries like the GT3B. And when running on 4 batteries they suffer from glitching themselves.
I've done a test with a FlySky GT3B and a RadioLink RC3S and when close to one another the GT3B will cause the RadioLink to glitch like hell. This is reduced if the RadioLink is run on 3S rather that 2S though.
There are numerous reports of FlySky's causing interference and they have been banned on many tracks, eg:
