This is particularly useful on launch when coastal soaring so you can get away from the compression at the soaring ridge in strong wind.
The RAST system keeps the Apus RS very stable and easy to control even with open trimmers. The trimmers can be quickly and safely grasped and closed if necessary using the stitched T-handle.
The uncertified trimmer riser can be purchased only as an optional accessory for a cost of Euro 189 gross (Euro 119 in combination with Apus RS order) incl. quick links and must be ordered separately. Since the Apus RS has no certification with trimmer risers, it can thus be converted back to the version with certification, if resold.
