"Perhaps try to get some introductions through Randy, as he is located in Japan, which has extensive agricultural spraying with RC helicopters. Though that is a challenging environment, mountain valleys obscuring GPS (so RTK support), extensive…"
"Considering the active DJI hacking scene this was inevitable. Even if DJI wasn't doing something shady, the number of holes/bugs makes this a problem. The flipside being opensource is in that weird middle zone where transparency is a blessing…"
"Most conventional centrifugal/axial microturbines are fuel guzzlers to be sure, and the typical efficiency boosting solution of recuperators does no favors due to weight.
Rotary ramjet style supersonic turbines in theory can reach diesel levels of…"
"Would concentrating the hardware to essentially a battery rotor hub and joining 2 together (common payload shaft, functionally independent, but one slaved to the other wirelessly) to be a coax be another path?"
"At this scale though, are generators confined to two-stoke oil premix fueled piston engines? Will there ever be a viable microturbine turbogenerator with foil bearings to avoid the lube issue and use straight gasoline or diesel? Will Liquid…"
"Their previous X quad is interesting, but with the available vectored thrust, an H style quad that can also fly forward more efficiently using full thrust of 4 rotors (rather than losing some thrust due to cant) would be great for a commercial UAV.…"
"What about Quanergy's S3qi solid state LIDAR? They appear to suggest that they are single chip 3D with 120 degree field of view. Not clear if they use MEMS, or actually are similar to to the MIT/DARPA work."
"Weight and deployability probably. A tethered multi with power up the tether has less weight issues than a balloon, and much easier to deploy on short notice from small hardcases. Power supply does become an issue though."
"With Softbank now owning ARM, I wonder if Randy could make an appeal to Mr. Son directly for a reference ARM design for FC+basic features SoC, as a drone network fits into a cellphone carrier's IoT plans? Quite a few cellphone chips are…"
"So maybe to be clear, should ArduPilot clearly host the reference board open hardware designs they work with? So perhaps fork/host Pixhawk2, rebrand it, and host it as the preferred reference board for implementers?
Since ArduPilot cut their…"
