Actually, no. The angular momentum of each pair of
counter-rotating engines cancels out, as long as they are spinning at the
same rate. There will be slight gyroscopic effects when the two engines of
a pair are at different throttle levels, but in the flight regime
contemplated for Gizmocopter, these throttling differences will be slight
and transient.
