Geared Aerodynamic Pan and Tilt

From my build page-

Having designed and released a pile of different Pan and Tilt units I decided to try and make something a little different. I came up with a list of simple design goals that were based on requests and experiences with other PnT's. The list then, in (my) order of importance is:

*Lighter and Faster than my HD Pan and tilt which is around 100g

• New weight is ~80g with the components shown here

*Is smooth and precise with excellent centering

• With a new, fully programmable digital Hitec HS-5245MG servo, it is extremely smooth and centers beautifully

*Is more aerodynamic

• Now with both servos mounted below the deck, it is very aerodynamic

*Can be made from off-the-shelf components

• All but one component is made from standard off-the-shelf parts (see text)

*Rotates 360° or more

• Rotation can be programmed from 236° to 398°

*Tilts down 50 degrees or more

• Tilts down 42° (see text)

Mechanical Specifications-
-Total weight with all hardware shown - 80 grams
-Pan rotaion - 236 - 398 degrees
-Tilt range - 0-42 degrees (down)
