Steps 22 and 23
•
Take the 6 semi-circular pieces from the small balsa sheet and glue them to
the front of the upper cowl assembly, one at a time
•
Carve and sand to shape
Step 24
•
Remove the lightening cut outs from the fuselage.
At this point you will need to ready your plans on your building board
Place the plans on the board and pin in place so they stay flat. Cover them with
polythene so that glue does not stick the parts to the board.

Wings
Notes:
•
There are 3 different rib types. Identify them before removing from the
sheets as follows: from inboard the first rib is the short basswood one, the
second has no cut-out in the top edge. The remaining 4 ribs, with top edge
cut-out, go towards the outboard end.
•
The ribs are extremely fragile so handle carefully and try not to apply a lot of
pressure when fitting over the spars.
