The R44 news has a turrent on the nose.
Fitting a second stabilised camera is not possible.
Fitting an extra internal camera doesn't cover much of a weight penalty, although Im not sure what that does to certification as you are adapting part of the aircraft.
So perhaps they mean adding another downlink which is an optional extra from Robinson is carrying a weight penalty.
