When initially started designing for this series of drones the priority matrix was reduced to a single design element... ie performance. By that I mean maximizing the aerodynamic efficiency of…

 I was feeling that lucky that decided to try the auto take off, On my previous only flight I only tried manual, circle mode and RTL which seemed to work…
