We chose the Chipmunk as it is a generally admired aircraft in the GA scene, has some aspirational and historic overtones, makes ex-cadets go all misty-eyed (jump, jump John!) and both my Wife and I have had some terrific fun flying with Janie in hers.
It was cockpits like the Chippy's that we designed the Wristboard for, so you don't have to wear the gro-bag and scribble on your legs
