"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…"
"Good news, congratulations, Sander! One question concerning the telemetry of the DeltaQuad: you mention a 4G data link, however, is there also any solution for areas without mobile network coverage, e.g. LR VHF or similar? "
"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…"
