Uh, is that the thread topic waaaay over there? Oops, well sure, quads with two motors per arm, one mounted upside down and spinning the other way. Usually so you can carry heavier weights (cameras. bigger batteries) without the added extra weight of more arms, as in a true OctoCopter.
They're all contributing to the lift equally, so if one fails, that's now half the lift of the other three arms. It's not like you only use 4 of them and when one dies the other kicks in. Although in Attitude Mode
, the brains will
probably try and spin up the working one harder to counter the tipping - with variable results depending on how loaded up the Quad is. If the total
amount of lift you now have available is less
than the weight you are carrying: you're going down...
If not particularly loaded up, you've got more leeway for survival, for sure. If flying in Manual/Sport mode
...probably no chance you'd save it without the reactions of Spider-Man.
