SONIC OWNERS MANUAL
22 Version 1.01
Trim Speed
Trim speed adjustment can be achieved by moving the hang loops forward to increase
trim speed or aft to bring the speed closer to stall. Once again, never move the loops
more than 1/2” at a time, ensuring that they are secured in their new position. At any
stage it is unlikely that adjustment beyond an inch or two is ever necessary. Should you
feel that greater adjustment is required than please ask your dealer to retest the glider.
After many hours of flight time the trim speed will gradually change as the sail stretches
and the airframe acquires a memory to its tensioned curves. This is a normal process
for all gliders and allowance for this is incorporated in the maintenance schedule.
Whenever you make adjustments, only change one thing at a time. If no improvement is
apparent after making several adjustments, consult your dealer and have the airframe
thoroughly checked before getting too far from the Sonic’s original trim settings.
