Puma 13.5
Owner’s Manual
The view below is shown from the back of the glider. If your glider has a different setting then you should
mark the tip cap position before returning them to factory standard. If their setting is asymmetrical and the
glider flies straight then returning them to the symmetrical standard setting is likely to introduce a slight turn
in the glider.

CHECKING WASHOUT
Washout rods
Damage to the leading edges or washout rods can alter washout heights.
The washout rod heights should be checked periodically or after a heavy landing or crash. It is especially
important to check the washout heights if a new leading edge component has been fitted. If the washout
heights are below those specified they should be adjusted up to the correct heights. If it is not possible to
adjust to the minimum heights DO NOT FLY. Please refer to Avian Ltd.
Recommended method
The washout rods are factory set and should not be altered by the pilot except in the way outlined in the
tuning section of this manual. (See Tuning out turns on page 18.) 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. Note the
average
height of the left and
right washout rod is important though the two heights should not differ by more than 20mm.
The washout angle can also be checked 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. With the glider tensioned, but the VG fully OFF, the heights of the
batten ends can be checked. The heights should be measured from the centre of the batten ends perpendicular
to the flat surface. These heights correspond to the washout rod angles. Minimum heights are given in Figure
9.

Alternative method
The previous method of measuring the heights is the preferred method, however if a suitable large flat space
cannot be found in which to measure the heights and an inclinometer is available (e.g. in a competition
setting) then the washout rods can be measured by the following method:
1. Fully rig glider and pull VG fully ON (it is important to have first checked the VG range is correct
before applying this method)
