I used a jigsaw to cut out the hole in the lower fuselage where the nose landing gear doors will go. An inset is molded into the fuselage in the right shape and location – care was take to leave an even flange around the opening. The NLG doors are supplied as one piece (to be separated later). These had to be sanded to fit the NLG opening with about 1/8″ clearance all around. The jigsaw was used to cut out four NLG door hinges from a thick piece of fiberglass layup – slow, blade-dulling work.
