I have two flight instructor trainees who are short. Using cushions for height and to assist with reach however achieving full up elevator is limiting the thickness of cushion behind.
I see from https://champcitabriadecathlonforums.com/threads/rudder-pedal-extensions-anyone.186/ that "I spoke with ACA, and they do in fact make rudder pedal extensions".
Would you please confirm that and provide some information about them please?
