But there's bugger all skill in a lot of the stuff in the MA, short of people deliberately choosing to NOT fly uber-planes. There'd be no reason why the speed of the V1 should not be as per real - the faster fighters of its day could catch it, just, some would need to shallow dive after it.
I'd vote for having their payload do what it would if it were a normal bomb, but allow quite a few of them. They were very inaccurate, and small, and hard to hit, as well as fast.. ANd if you ran out of ammo, you'd have the fun of trying to tip them over with your wing.
But I don't think theyd add much to the game as it stands ATM.
