Assembly Alignment Information
In order for your new model to fly straight and perform both inside and outside type maneuvers consistently and accurately with the same trim settings there are a few critical alignment procedures that must be followed as you assemble this model.

These procedures are in addition to any other alignment details described in our instruction book.

Unless otherwise noted on the individual kit plans, the incidence angles of the wing and stabilizer should always be set at 00 in relationship to the motor thrust line.The following procedure should be used to verify these settings.

First a thrust reference line that is parallel with the motor mounts should be drawn the length of the fuselage using a felt pen. In lieu of a felt pen line, a straight edge along the top or bottom of the fuselage could be used as this reference line. This line will now become your reference point in verifying that the wing and stabilizer are set at 00 incidence or in other words parallel with the motor thrust line. Methods will vary depending upon the particular model you are building.

This incidence angle is determined from an imaginary line drawn horizontally thru the center of the wing and stabilizer airfoil sections and then measuring back to the motor thrust line on the fuselage at the leading and trailing edges. (See examples). When the dimensions at the leading and trailing edges are equal, it is assumed that the component is set at a 00 incidence angle in relationship to the motor thrust line.

Many wing and stabilizer locations are possible although the method of verifying the incidence angles would remain consistent with the examples shown. Model aircraft of bi-plane and canard configurations may require incidence angle settings that are unique to their particular designs and will have that information furnished in any appropriate kit.
