Wow, there’s just a million options !!
If it’s easier, I am willing to just buy a separate microprocessor, or microcontroller for every separate task group a drone needs to operate. Might sound stupid, but I am not trying to just build little domestic (under 25 Kg.) drones, I want to build large automated aircraft. Think SUV size, not microwave oven size.
Something that can carry 100-200 lbs. A few lbs of extra micro hardware won’t kill the flightpath distance.
Even larger models may happen too.
A VTOL search & rescue drone that drop a bunch of emergency survival supplies in to help an injured skier or stranded snow mobile won’t mind a few lbs extra weight.
There are RC aircraft the size of most cars, so the controller weight isn’t a huge issue. If I make a smaller proof of concept drone that is under the 25 kg limit, a pound or 2 extra weight may reduce the battery flight time by 20% or 30%, but that won’t deter investors. They will see how switching from the weak little LiPo batteries on the 1st prototype to full size aircraft internal combustion engines on production models will eliminate the short flightpath.
