From my experience in flying drones in wintery mountains, it could be a battery failure. Cold batteries suddenly drops in voltage, too fast for the failsafe mechanisms to trigger. Can explain why it drops like a brick and not slowly descends.
- pfortuny 11y agoThat is why true "failsafe" mechanisms tend to be mechanical more than electrical: less prone to failure.
- xgbi 11y agoHow do you provide this in a quadcopter? The rotors are too small to allow autogiration...
- pfortuny 11y agoyou might use something different, like a parachute.
- Ao7bei3s 11y agoNo, that's been tried and it doesn't work well for multicopters. * They're only effective from quite some altitude, much higher than you typically fly multicopters * They'll still just soften the landing somewhat anyway * Multicopters are much more fragile than, say, EPP planes, * You have to make sure they don't get caught up in the props * Also you need to find a reliable way to trigger them -- for model aircraft in general and multicopters in particular, humans are way too slow and sudden high accelerations in arbitrary directions are common for multicopters.
