carabiners.

2. Speedbag adjustment

Correct speedbag length setting is essen-

tial. This defines the body centre of gravity

position and therefore sets the speedbag

angle in flight. For best aerodynamics the

underside of the speedbag should be

horizontal. First, completely loosen the up-

per, blue speedbag lines

. Then set the

correct flying angle with the grey speedbag

lines

. If the result is too steep (speed-

bag nose down) shorten these lines (C of

G goes back): too flat (speedbag nose up),

lengthen them. Make small corrections

(2 cm steps max) to obtain the correct

length. Then shorten the upper blue lines

for the desired footboard angle – com-

fortable feet. Finally set the lower blue lines
