"Boring and useless.
Says nothing about the real data acquisition. What data are they capturing? How often? Are the data usefull, can the farmer use them to correct/enhance farming (without spending much more money)?
These are the questions they…"
"Very good! Professionally done, way better than the majority of the competitors...serious engineer and designer behind this, no amateurs... I can't see any big flaws with it, even on the price side, that is what it should be. The only "thing" is…"
"Cedivad, thanks for the info, please put them on the webpage too, with some pictures of the actual devices and maybe the user manual or the detailed menu (they look very nice, you should show them on your site, not in a third party review)
"Great design, mine has a lot in common! Always wanted to try a fixed pitch tail rotor to save weight and complexity, but had no time and not sure was worth it. Is it? Does it work correctly?
Were are you located in France? maybe we are not that far…"
"Traditional helis now are serial killers and giant 20Kg 30" prop multirotors are safe crafts... but came on, guys! It's ridiculous. A swashplate with 2 links is complex mechanics, while 4 engines with a gas motor and generator is simple?
"How much fuel did you have on board? (gasoline/oil mix)
What motor/generator are you using? Fuel injected/carburator? Did you have electric starter onboard? Is it reliable? How many hours are you getting between engine rebuilds?
"How much more efficient in forward flight is compared to a conventional elicopter? How fast is the cruise speed? 10000mAah means nothing if you don't state the voltage... (it's 12S, so 44,4 Volt, right?)"
"I second what Rob said! Have you tested another esc to compare data? Probably a much lighter Esc32 (for example) will do so much better in terms of efficiency (it's also a lot more tuneable) and save a lot of weight. Motor and prop too don't look…"
