Hi Guys, I highly recommend cutting off the bottom of the gear doors. If not cut, they will either get damaged when the struts compress or cause the model to flip over, especially on a grass field. The factory put marks on the doors to use as cut lines. These are scale marks too. Take a look at 3 view drawings to check for yourself. On the full scale aircraft, the door bottoms flipped up out of the way, best I can tell. This is similar to the Beech Stagger-Wing gear door mechanization. My 2 cents. This is a photo from the FW-190 I am putting together for a friend. Good luck. This is a great model.
