I've seen enough video shot from drones now that this proven technology would offer us a means to capture all-around video images of a fully-tufted test vehicle.
Any controlled stretch of roadway or inactive runway/taxiway could provide a safe venue for critical Reynolds number testing of modified vehicles without aerodynamic interference from the 'chase' vehicle.
A 'stable' RC fixed-wing aircraft,helicopter,or actual multi-rotor drone with camera turret would do the trick.
Owned,leased,or rented with operator,the image capture could provide critical information about mods as a prelude to a wind tunnel visit.
What do you guys/gals think it would cost to get into this game?
