Carefully tap shaft W into cap U until it blocks.
If you find a rotary encoder
assembly A8 inside this
construction kit, you can
continue with drawing 7.
Insert the wires of R3 into
the openings of component R2
as indicated in drawing 4,
respecting the colour indications.
Solder the wires onto
the rotary encoder R1,
as indicated in
drawing 5 and 6.
Place component W/U as assembled in drawing 1 onto t
he rotary encoder shaft. There is a small indentation in
the rotary encoder shaft. The opening of component U
contains a small ridge, which fits exactly into this
indentation. Make sure ridge and
indentation fit completely.
Connect component M to component A8, making sure
no glue comes into contact with the rotary encoder,
with the rotary encoder shaft or with component W/U.

CAUTION! The servos cannot be connected as shown in
picture 17, 18 and 19. The connector of the servos
has to be cut off and the isolation of the wires should be
removed somewhat to enable the wires to be soldered
directly on the PC-Board, due to lack of
space for connectors!
