"Hi Chris, thanks for raising attention to the project.
As I'm currently working on comparable topics (detecting diurnal mammals instead of humans) in the same climatic environment, I am most interested in any investigation of the applicability…"
"@Bart Theys, this brings me to another point: my aerodynamic knowledge might prove me wrong, but I'd think that the static thrust is different from what you'll get in flight. As such, one might consider measurements in a wind tunnel rather…"
interesting performance data of your concept. They fully correspond with my wish list. What stage is the project currently? The airfoil and wing section seems very thin and small. What's the MTOW you consider for this plane?"
"Thanks for sharing your experience and the steps of development of this exceptional aircraft. Furthermore, I am happy to see some follow-up on the RAPTOR EV to get this craft commercialized - sooner or later ;-)"
"Pretty interesting setup combining the efficiency of the believer platform with VTOL capabilities. Amazing ! Do you have any news about the flight test, e.g. flight performance, duration, behavior in wind, etc.?"
"From the point of view of efficiency (and thereby noise), larger props that turn slower are beneficial. As you said already, they will all do their job, and small props increase responsitivity and therefore faster control. Now, it's the…"
"I wonder where and how much you gain in flight performance and efficiency compared to a simple quadcopter. The flight trajectory displayed in the video seems more like a quad with a wing and not really like a FW."
"Second point, which is not completely clear to me: the product comparison sheet shows a flight time of 2 hours with the 23Ah LiPo, however the specs (of the EU version) states a flight time of 1 hour 50 minutes with the same battery. I…"
