Looks like a practical and efficient design. Add a high-strung engine/generator inside and I’m in.
Batteries for hover, climb, and backup.
I like your sense of humor!
The video quotes numbers: 60dBA for a helicopter, 38 dbA for the Heaviside, in comparable conditions. dBA is a logarithmic measure, so the ratio of noise is 10**((38-60)/10) = approx 0.006. The Heaviside generates about 0.6% of the noise of a helicopter in those conditions. Sure, be snarky about the marketing copy using imprecise language, but give the video credit for providing more rigourous numbers for those who care enough to do the arithmetic.
OK maybe this is splitting hairs but it’s only properly 100 times quieter if it’s the same weight as a Jetranger.
But if it is a 3 surface design with power-out glide performance then it’s pretty much what seems to me like the ideal design. I was thinking lift fans on each wing tip for maximum redundancy, like a 6 fan commercial camera drone, but this seems close and might be more practical?
