Best books are by Remp and by Dressel & Griehl. Also, try to register at the Luftwaffe Experten Message Board and track down some of their threads on the 219. One in particular is basically an encyclopedia of all the latest info.
Discount anything you read about 6 Mosquitos in 10 days after Streib's initial sortie - didn't happen.
One more question does it fit the bill to be added ? if so would you guys fly it if it were added
Short answer is no and no. It was used in squadron strenght, however it was a dedicated night-fighter, and we don't have night. Also, take the same engines as are on the Me 410, put them on a larger, heavier aircraft, then put flame dampers on the exhausts and festoon the nose with aerials. Not a winning combination.
