Notes: -
The (Wortman) wing section is sensitive. Stalling speed in rain increases 10 - 15 Kph and the tips stall. Annual check - The release cable cuts through its guide tube above the front pilot’s feet. Annual check - Undo the rudder cables at the rear pedals, pull the cables out and inspect them.
