Missing RNGFND1_RECV_ID in Mission Planner

The RNGFND1_RECV_ID parameter is not showing up anywhere under the Full Parameter List neither the Advanced Parameters in Mission Planner (1.3.75, build 1.3.7883.26333) with ArduCopter (V4.1.2).

Several parameters do not show up… Also pressed CTRL-F and Parem Gen. No changes. I need these parameters for custom rangefinder setup.

Are you using latest dev firmware ? RNGFND1_RECV_ID introduced in 4.2dev.

No, we are using 4.1.1. There are several paramters not showing up, which I have seen pop up on systems demontrated on youtube, with older firmware. An example of another is CAN_D1_UC_NODE. Does not show up for me, so I am not sure if I am missing something in the setup process.

Which youtube video are we talking about ?

I got them to show up after rebooting the flight controller. Thanks.
