Wood Parts Identification
Dimensioned balsa and hardwood parts are easily identifiable by comparing their shape and dimensions to the plans and to the
COMPLETE KIT PARTS LIST. On the other hand, proper identification of the different wing ribs, wing sheeting, fuselage
formers, etc., can be confusing because some of them are very similar looking, when in fact they are quite different.
Use the following KEY TO LASER-CUT PARTS diagrams to correctly identify each part. Use a pencil to label each part with its
name or number, before removing the parts from the laser-cut sheets.
IMPORTANT:
The laser cut parts contained in this kit are extremely accurate in outline and fit. They are meant to be used directly out of their
sheets, without any trimming or sanding unless specifically called for in the instructions. The laser cutting process produces a
brownish edge to the parts and, in some cases, a blackout edge may result when cutting harder plywood parts.
CA adhesives work perfectly on these parts and they do not need to be sanded to remove the discolored edges. In fact, sanding
the edges of laser cut parts can change their shape and/or dimensions, resulting in a poor fit. DO NOT edge sand the laser cut
parts in this kit.
