Servo for raising / lowering tamiya landing legs

[mavrick0]

You can't just hook the servo up to an on/off switch and have it work. The servo needs to see a signal to tell it what to do so right off the bat you'll need a servo controller unless of course you pull the circuit board out of the servo and wire directly into the motor. The other as mentioned is you'll need a continuous rotation servo. Standard servo's have built in stops in the case as well as the potentiometer that sends info back to the board to tell it where the servo output is.

My question is why do you want to use a servo over the standard motor/gearbox that comes with the kit.

What I'm looking at doing with one my trailers is possibly trying out some firgelli actuators as the legs for the landing gear.
