Some compulsive guys fit a little spring made out of a single loop of fine music wire to keep tension of the front 1/3 of the nose door........so not to hang loose at any time....on the KC, when the gear is down, it actually overextends the door to about 110 degrees and keeps it tight against the strut with a little block between....up in the air of course you can't really see much, except that it does close completely.....
