GLIDER ADJUSTMENTS 

 
It is possible to lower the sprogs settings of your glider without compromise safety (se 
the table bellow for the sprog angles). All figures in the table are given after DHV tests.

The glider with a tail becomes more stable in roll, you may feel that the roll rate is higher 
than without a tail. To improve the roll rate of the glider with a tail and decrease the pitch 
bar pressure we recommend rotating both LE #3 plastic caps one hole down. Changing 
the side wires for shorter ones (after consulting with Aeros only) will help to improve the 
roll rate. 
 

MAINTENANCE AND STORAGE 
 

The tail does not require special maintenance. Although it looks rather strong, special 
care should be taken to avoid point loading of the tail. Clean the tail with a soft rag from 
the moisture and dirt before storage. 
 

NOTE: 

The storage bag for the tail allow storing the tail with one outer section and 

central section assembled in one compartment and with another outer section in the 
second compartment. 

 

The tail must not be subjected to load during storage or transportation. Make sure it is 
protected from mechanical damage, soiling or moisture during storage or transportation. 

 

WARNING

: USING CERTAIN TROLLEYS FOR TAKE OFF DURING AERO TOW 

WITH A TAIL MAY LEAD TO POTENTIAL DANGER. THE MATTER IN QUESTION – 
TROLLEYS WITH A DEAP V-SHAPED KEEL SUPPORT.  

When the keel tube goes too deep in the V-shaped support, the support upper points 
may (most probably will) catch the tail during take off.  

The keel tube rises from the support at the same time with the glider lifting off the 
trolley.  Large deepening in the support will lead to the tail catching the upper points of 
the support and the glider pitching nose down and crash right after departing from the 
trolley. We have never discovered this problem because we are using different trolleys 
where the keel tube of the glider doesn’t go deep inside, the deepening for the keel tube 
is no deeper than the keel tube diameter. Having discovered this potential danger, we 
recommend to pilots when aero towing with tails to use only trolleys, where the 
deepening for the keel tube in the keel support is no bigger than the keel diameter.
