Throttle return springs work, sometimes though something as easy as a hairband around the carb neck to the ball does the trick.
Failsafe only gives any protection while you have power. So basically run your battery down, lose your battery connection (have had it happened to me before, wires dragged), and failsafe will do nothing to stop your car from going bezerk, while a well=placed Throttle return will shut the carb. Of course the best protection is to have both but if I had to choose I'd make sure i had throttle return before a failsafe.
I think you're right - both is the only way, really, to go.
Although I've never lost so much power in my batteries that the servos weren't just going berzerk instead of dead. . .in which case a failsafe is a better item.
