can i mount an extra oplink modem on a drone wich flies between me and the oplink controlled drone in order to use it as range extender? thank you

OpLink does not currently do that.  There may be some other telemetry boards that do it though.

Well ... You might be able to have one OpLink on ground, two at the mid point (one talks to ground and the other talks to the far aircraft) and one in the far aircraft.  The mid point pair would be wired together.  I forget some details about whether the code would allow that.

You would want to run the two segments on different (non overlapping) min-max channels, and even then you would probably have interference.  Maybe use CP-left and CP-right for the different segments.
