2. Rest the keel tube on a support and using the angle meter as shown on the figure 39, set the
angle meter to zero. Maintain this keel tube angle during further measurements.

3. Place the worktop of the angle meter under the middle part of the inner sprog close enough
to the sprog wire attachment point so that the entire worktop surface of the angle meter touches
the sprog (Fig. 40).
The scale of the angle meter will show the sprog angle.
The inner sprogs for Still TL should be set to 11 deg.
Figure 41
To adjust the main sprog angle:
1. Remove the pin from the sprog threaded
adjuster at the front of the sprog. To raise the
sprog angle turn the end of the sprog threaded
adjuster counter clockwise. To lower the sprog
angle turn the end of the sprog threaded
adjuster clockwise (Fig. 41).
2. Re-install the pin to the sprog threaded
adjuster and press down firmly on the rear end
of the sprog to seat the cable before checking
the measurement again.
11. REMOVING THE SAIL FROM THE AIRFRAME AND RE-INSTALLING
Many maintenance and repair procedures will require the removal of the sail from the frame.
Please follow these instructions when removing and reinstalling the sail. Please read all the
instructions for each operation before beginning.
SAIL REMOVAL
You will need an unobstructed area 2 m by 9 m (6x30 ft). Make sure the surface is clean. If it is
abrasive, you should either cover it with protective tarp or be extremely careful not to scrape
your sail.
Since Still TL is a single surface wing the sail removal is rather easy to perform.
1. Unzip and remove the wing bag and put struts, battens and the control bar aside. Remove
Velcro straps and all protection bags from the wing.
