Hello Rmackay

Maybe you can help me; I don’t know how, or where, to share a “new feature” proposal, in order to evaluate it for the “team”, maybe it is worth it. The idea is to open the possibility to mount a sonar to Multicopter, in order to measure the depth of the water body. I have some ideas that I want to share…

Hi @sofamio,

Enhancement requests can be raised here in the issues list.

Thank you, I placed my idea on it.

Thanks for testing everyone, 4.4.2 is now a stable release.
