When an RV-14 (and RV-10) is built and rigged per plans, the ailerons and flaps (when fully retracted) are in a neg. 3 degree reflex position.
To obtain a zero setting you just lower the flaps 3 degrees from the fully retracted position and then label that as the zero setting.
We use that position for no flap take-offs and climb mode, and only fully retract the flaps to neg. 3 for level cruise flight on the RV-14 and RV-10.
