Servo
The servo is equipped with a number of arms. Choose the arm you want to use and mount it on the
servo. Make sure you use the small screw to attach the arm to the shaft of the servo.
Now position the servo in the bracket like this and screw it into the servo bracket with two sheet metal
screws.
As servo we recommend the Hextronics HXT900, or the Turnigy TG9e as analogue servo. Or if you want
to use a digital servo we recommend the Turnigy TG9d or the MX-95

Feather steel wire
You can use the spring steel wire to effect the transfer between the servo arm and the object to be
moved. You do this as directly as possible. Every form of bending, Z-cutting and
V-cuts are not necessary and actually counteract the movements.
The most common way of mounting is directly under the switch tongue, which makes the distance and
movement of the servo as short as possible. The different holes in the arm can be used to play with the
stroke of the servo. If the stroke is too short or too fast, you may prefer a hole closer to the axis. If you
want a direct movement, then choose a hole as far away from the axis as possible.
The distance from the arm to the servo is irrelevant. If you cover a distance of more than 5 cm at right
angles to the arm and in line with the movement of the servo, you should use a tube to guide the spring
steel.
Tip: use the sticks of a cotton bud. That will save you a lot of money.
