It's probably worth mentioning that Hoerner tips are an attempt to reduce induced drag caused by the wingtip vortices.

Adverse yaw and dihedral are entirely different subjects.

Omitting the Hoerner tips does little more than effectivly reduce the wingspan by approximately double the width of the Hoerner tip.

Wind tunnel tests have shown that the Hoerner tip has little effect on aircraft of this size.
