Cowling Installation:
The cowling is installed with a single pre-installed bolt on the top half, from
the inside of the fuselage going forwards, and two additional bolts going
through the cowling from the bottom.
With the cowl off, turn the model over, and place some small strips of
masking tape in line with the two bolt holes. Draw a straight line on the
masking tape going over the holes, and mark/measure where the hole is
relative to the lines.
Install the cowling, tightening the top bolt. Place additional masking tape
on the cowling, and with a ruler continue the straight lines drawn
previously.
Measure back to the marked point where the holes are, and then remove
the cowl and drill out the two necessary holes with a 2,5mm drill bit.
Re-install the cowl using the top and bottom bolts.
