Right now, the only thing limiting its acrobatic flight capabilities is not the flight model, but simply programming the manoeuvres in. This last task is almost insignificant in terms of difficulty, when compared to the challenges of the vibration dampening system, systems integration, and flight dynamics model development.

Automated gunfire detection.
    XL: Total weight, ~11 pounds. Payload: A small video camera.

    Predator: UHF and VHF radio relay links, a C-band line-of-sight data link (range 150 NM) and UHF and Ku-band satellite data links.
