We recently brought Sub into the Wiki as a true vehicle site (still a work in progress). So I have been discussing Sub with Randy and Willian, and I want to promote Sub more into the hobbyist area.
So I have proposed doing a simple FPV underwater ROV that would appeal to a hobbyist AP user. Goal is that it could be built DIY with readily available components and use a surface box with RC and fpv VTX tethered to ROV. Code will be developed to bring RC back into Sub for pilot control which I am working on already (Rc is in, Aux switch under debug, FS RC actions and mode switch next)
