He-111H-2 now can serve as carrier for Fi-103.

V-1 AI reworked a little.
As V-1 is unmanned, it cannot launch itself, so U have to designate strike point with no specific target for carrier aircraft.
No sense to set strike point for V-1. V-1 executes 45-degree dive upon reaching its final waypoint, whatever it designated as strike zone or not. I'm not recommend to set a specific target for V-1, as it will running circles around, trying to hit. Another reason is that, if target will be dectroyed prior V-1 arrival, V-1 will just running circles around, or will try to RTB with disastrous consequences 8)

V-4 (still placeholder) behaves itself as regular piloted AC, so U have to set its final waypoint as strike point to make craft to commit kamikaze attack.

Pair of sample missions, demonstrating air launch and Fi-103 kamikaze attack, can be found in Single Missions > Germany > V-1 and V-4 (changed a bit).
