The upper right and lower right points on a Vn diagram correspond to maximum positive and negative n factors and maximum dive speed; which is assumed to be 1.25 to 1.5 of maximum level flight speed; which could change depending on your design. It also corresponds to the positive low angle of attack and negative low angle of attack load cases.
What velocities are assumed for the upper left and lower left "corners" of the diagram?
BDD
