Yes, Vector vision is very good for the higher altitude work and for wide angle low level work , but its camera system cant do big closeups from a distance.
A stabilised TV gimbal can have a 22x or 42x zoom. What we are shooting is a doc so big closeups are important.
The snakecam system fitted to an Aero Commander 700 fits between heli and lear jet speeds is a good option.
