types
All this talk about offering the best equipment for the job makes me cringe.
A jetranger with an STC'd sliding r/h rear door (cameramans harness with STC'd attach point) should be the minimum for that type of work (that's if they're serious about offering the best equipment). Ideally a Squirell.
If memory serves me correctly, I don't think the R44 (not sure about the Enstrom as I have never seen one up close) even has a hardpoint to attach an approved cameramans harness for filming, is there an STC'd mod for the R44 for an attach point?
