MSH-850 and Flyability Elios (web app integration)

we have a series of questions regarding the MSH-850 and Flyability Elios drones.

  1. Is ArduPilot compatible with these models?

  2. How do you connect to the drones from a web application to get its flight information, especially GPS coordinates and video streaming? Are there any APIs?

  3. Are there any ArduPilot APIs that perform these operations or we need to use drone manufacturer APIs?
