"No idea, why my comment has been deleted a few days ago. Nevertheless, I stated there, that the video features a variety of aircrafts, ranging from Sparkletech's Eagle Hero and/or Technosys Thresher-03 down to the product line of JOUAV…"
"Indeed, great performance for that "bulky" X8 airfoil ;-) I'm highly interested in the "official" version of that A/C and it's performance - keep me updated.
Btw.: what's the landing radar log? Are you using radar…"
"My 5c about efficiency of transitional A/Cs: in terms of parasitic weight, I agree with you that this design is as minimalistic as possible, however the huge thrust needed for take-off and landing demands powerful motors and props, which are (often)…"
"Hey Joe and Gisela,
as a wildlife biologist, I deeply appreciate your dedication for the conservation of wildlife. As a mechanical engineer I really love your approach of optimizing established techniques and technology by the local means. This…"
"Great plane and perfect control. I am looking forward to the conversion kit, as the flight time of V2 (90 minutes) @ 100km provides a powerful package for big area surveying. Keep me informed when and where to get it ! "
"Nice design, Dorjano, however, this solution is not very efficient either, as you're still using 4 motors for propulsion in airplane mode. Just think about the power used during this airplane mode. Furthermore, the propellers used…"
"Regarding the electric drives for the VTOL mode, I would guess that you should be able to lift 12kg with 4 18''-props. A short calculation in ecalc.ch proves that using e.g. Plettenberg motor Xtra 25-12 (265kV) with a 6S setup and 18x12…"
"The wing span must definitely be a typo mistake. If you look at the picture on their homepage, the guy holding the plane must otherwise be a midget... I'd estimate it at about 3m, at least. Although I think that 1kg payload can take quite a bit…"
"Great, thanks, this helped me quite a bit - but no, I am definitely not an expert in this. It looks, however, as if my guess was right then, correcting the lens focal length of the monochrome sensor to 3.02mm, instead of 3.98mm.
BTW, for the…"
