For an airplane to depart controlled flight, the pilot has to exceed the aerodynamic limit with yaw present. This is a short video clip of a skidding departure. In this case, the stall occurs with uncoordinated rudder. The airplane stalls, then immediately begins a snap roll. Note the significant wing drop that occurs as soon as the airplane stalls:

One RV handling characteristic is how well the flight controls work approaching and during the stall. This characteristic combined with a lack of aerodynamic warning (buffet) prior to the stall at 1G, can give the pilot a false sense of security as he "eats up the aerodynamic margin," i.e., increases AOA and gets closer to the limit. The airplane feels solid, until it isn't and there is some unintended yaw present.
To address this, we decided to capitalize on the human brain's excellent evolved response to figure out what direction a sound is coming from. Garmin calls this "3D audio." Most of us call this stereo . In this short video clip, you can hear the tone moving left and right in the sound field if you play the audio through stereo speakers or wear a stereo headset or ear pods:

The tone mimics the behavior of the ball. To coordinate, you "step on the tone" the same way you "step on the ball." A handy feature when you are trying to max perform the airplane and may be intentionally operating at reduced margin (i.e., flying close to stall). It's drawn my attention to inattentive feet more than once.
