Extended Data Fig. 4: Conservative measurement sensitivity analysis revealed a minimal effect on pitch stability and agility metrics.

We assumed that experimental error on the centre of gravity measured for the torso and tail was ±15% of the torso length (up to a maximum of 4 cm) and recalculated the (a) maximum pitch agility for stable flight (most negative values in Fig. 4a), (b) minimum and (c) maximum static margin. The estimated error ranges from panels b and c informed the bootstrapping analysis in Extended Data Fig. 3.
