servo motor question

Working on a camera mount for a small survalience helicopter. My elec pal at work is on vacation & I know nothing about motors. Is a servo motor direction easily reversed like a simple brush type D.C. motor?

Thanks guys,

they are driven by servos.

RC servos are quite different than the electric motors in your car
windows. In an RC servo if you reverse polarity it will either burn
out the servo, the transmitter or both. Most modern transmitters
have servo reverse switches to reverse the direction of the servo.

Thanks guys. My biggest problem is weight. He has a motor that offers 100 oz/in which is probably OK if I can limit the tilt on his 1# Nikon & balance the camera over the pivot point. My total weight constraint of (just my mount & tilt pieces) of about 2.5 pounds is a problem. Now that I know the servo can be reversed I can use a worm gear drive for the tilt as it won't allow the camera to back drive the gear train. Nothing is easy & I'm not getting ritch!

Thanks again,
