Narrative:

Aborted takeoff due to aural warning indicating automatic feather not armed. This experience was illustrative of a small series of mistakes leading to a larger one.

Third mistake was responding to ATC query 'XXXX, are you ready' in the affirmative prior to checklist completion. As a result the rush cost us time.
