|Time to Build Model and Diagrams||> 4 hours||1 hour 30 minutes|
- Wind gusts at the upper end of the specified operating range did not have a negative effect on control or maneuverability of the UAV.
- Light rain did not impede the operation. However, some later images were marred by rain droplets on the lens. This needs to be monitored in similar conditions and the UAV landed and lens dried if required.
- Timing did not allow the capture of oblique aerial images or any terrestrial images. However, overall model quality was not negatively effected with only some loss of resolution on close-up views of the vehicle.
- Aerial photography, in this case, may provide sufficiently detailed images to prepare preliminary crush analysis.
