Miga motors nanomuscle : servo substitute?
I was looking for a parachute ejection system for one of my small UAV and I found the miga motors nanomuscle. Cheap SMA system linear actuator (less than 10$ unit), I was thinking about using some instead of the servos on UAV.

I see high current consumption in specs and low torqe.
Sorry my ignorance, but in what aspect is this supposed to be better than a servo?

I wonder how accurate it is, or is it an on-off actuator? It's rather slow though, 4mm takes almost a second.

Dittos. Memory wire/muscle wire is really slow and high current. Also, they have an on-off characteristic. Linear operation is not recommended. OK to open a hatch, not so good to adjust aileron/elevator.
Fun stuff to play with, though.

Maybe the dynalloy flexinol will be better for this, I don't know, will try. For ejecting a parachute other linear actuator I saw are to heavy.
