A sub-micro servo with mounting
tabs clipped off.
Step 4: Construct the body by gluing the servos
together.
Remove the mounting tabs from all three servos with
diagonal cutters. The tabs are not needed for this project and
can interfere with the motion of the servos.
Next, join the servos with a few dabs of hot glue as shown
below. You do not need much glue to hold them securely! Try
to align the corners precisely to make flat surfaces for
mounting the other parts.
Try to align the corners.
Clip the servo cables, leaving at least 2" (more if you are less experienced with soldering).
Strip a small amount of wire from the end of each cable.
Cut and strip the servo leads, leaving about 2” of wire.
Step 5: Solder the servos and sensors to the Micro Maestro.
This step requires patience and care. A second pair of hands could be very useful.
Use solder to tin the leads of the servos so that they can be connected initially without
additional solder. Looking at the pictures below for reference, place the Maestro on the back
side of the body and place the middle wires over the front of the Maestro and into the holes
for channel 1. Holding the wires in these holes, pull the Maestro away from the body, then
touch the soldering iron to each connection so that the small amount of solder on the wires
melts and holds them in place. You should now be able to add more solder to each of the
connections, until the holes are filled and the wires are held securely. Check carefully for
loose strands of wire, which could cause shorts.
