Toppling V1s became the preferred way of destroying them, as shooting at them from behind and then flying through the explosion as the warhead detonated often created a few brown trouser moments. Some pilots used to physically topple them with their wingtip, occasionally resulting with a dent in the end of the wing, but usually the airflow created by the fighter's wingtip was enough to upset the V1's gyro and send it out of control.
Interesting with the Cougar however, but what piques my interest even more is trying to upset the Cutlass with jet wash from other aircraft.
