CHECKING WASHOUT:
Washout rods
The washout rods are factory set and should not be altered by the pilot. During initial assembly
the angle of the washout rod is set on the airframe without its sail. The angle is expressed as a
height from the end of the washout rod perpendicular to the flat surface the airframe is lying on.
The washout angle can also be checked (though less accurately) with a fully rigged glider by
measuring heights to the trailing edge of the glider as follows:
The batten profile should be checked and altered if necessary. The span-wise battens should
be checked for straightness. The glider should be rigged flat on a very flat surface without the
speed bar. Check that the washout rods are correctly positioned and the cords are correctly
adjusted. (The cords are adjusted so that the inner washout rods can not slip off the span-wise
battens.) With the glider tensioned, but the VB. fully OFF, the heights of the batten ends can be
checked. The heights should be measured from the top of the batten ends perpendicular to the
flat surface. These heights correspond to the washout rod angles. Minimum heights are given
on the next page.
Damage to the leading edges or washout rods can alter washout heights. If the washout
heights are below those specified below the glider should not be flown. Please refer to Avian
Ltd.
