the engines are the killer (which in real life they were also)
off the top of my head (and Harley has made changes to the system) but for the 229, you looking at 4 engines a plane, so 10 planes a day, 40 engines a day, you an do it, going to be using a good part of your engine production, and getting all 40 engines to be built is going to be ruff (you don't want to change over a 10/15 size plant to these)
hassle will be, the engines are not relieable, and the frame/parts are only a little better (each of these planes were all but hand made) so getting what you set up each day, will be HARDer then it looks
but, and a big but, that is a sweet plane, the rockets it carry are worth the effert if you can get it !
IIRC, it was 500 planes in stock, or a date being reached (again, IIRC jan or feb of 44)
but really, the idea, goal is to get the Axis Allied into the 109G-2a/G-6a, then move on up from there, it takes a lot of strain off of the LW production
