The rocket situation is not clearly similar to this one. In the first place, these craft are controlled by varying the speeds of the different rotors. That means that the thrust is not "in line with the angle of the craft".
- Retric 7y agoThey are still attached to the aircraft so net vector rotates with the aircraft. Take a modern twin engine aircraft and they can turn by changing the thrust from each engine, but when the engines are outputting identical thrust they don’t add stability. In both cases rotating the aircraft also rotates the net thrust in an identical fashion. Which means there is zero restoring force from the engines to return them to the original orientation. PS: Fixed wing aircraft get stability from their airframes not their engines. https://en.m.wikipedia.org/wiki/Longitudinal_static_stability https://en.m.wikipedia.org/wiki/Longitudinal_static_stabilit... Though in fighter jets this may be aided by active control.
