weakly significantp = 0.033
The effect of pivoting the radial arm The freedom of the radial beam to move up and down in the vertical plane (seesaw condition) had a weakly significant effect only on the dorsal stroke reversal point through an interaction with wing side (RMANOVA, F 1,9 = 6.35, p = 0.033, Table 2 ): namely, the effect of pivot type on the DSRP was inconsistent for left and right wings ( Fig 5A ).
