With this receiver they say it's "designed for KO PROPO FHSS protocol transmitters"

Does that mean it only works with ko propo fhss transmitters, or does it also work with generic fhss transmitters like a FlySky iT4/absima cr4t?

Or should I use a different fhss reciever like a FrSky VD5M 2.4Ghz 5CH Micro Receiver, which is also pretty small:

If you are working with a "sports" series Mini-Z chassis then the IT-4 or Kyosho 432P transmitter will bind directly with the chassis. Either radio has separate protocols for FHS and FHSS.

No I'm planning to buy an atomic BZ 2017 which comes with no tx/rx, so I need a small rx that works with a flysky transmitter (or absima cr4t transmitter, those are clones).
The absima cr4t works confirmed with kyosho sports series (with some software settings altered)

Or should I go for one of these when I want to use a FlySky FS-iT4/absima cr4t transmitter:

these digital protols are pretty confusing.

I would think that the first thing to do is select the transmitter. Once done then proceed to receiver choices. Though I have not experienced it, I have heard of range issues with the Das Mikro units as well as the bootlegged Gogolap clones.
