Assembling the ALPINA 3001 Champ ELEKTRO
Please don’t start work on the model until you have read through the instructions and
understand the purpose of the various components and stages of construction. If you
are not satisfied with the quality of any part, take it back to your model shop for
replacement before modifying it in any way.
The wings
Use your fingertips to locate the horn slots in the ailerons and flaps, remove the
covering film over them using the tip of a hot soldering iron or a sharp balsa knife,
then trim them as required so that the horns are a snug fit. The GRP horns should be
glued in the slots as shown in the two photos, taking care to produce really strong
joints.
The slots are machine-cut to approximately the correct depth, but you may need to
make minor adjustments by removing a little more of the foam core. Ideally you
should aim at removing foam inside the slots until the veneer is exposed, in this case
with the grain running at RIGHT-ANGLES to the wingspan.
While the glue is curing you can use the time to cut down the servo output levers to
the shape shown in the photo. Drill out the outermost hole in the output arm to 1.6
mm Ø to suit the threaded steel pushrod.
Centre the servos, then push the prepared output arms onto the servo output shafts
and fit the retaining screws.
