I dislike the tiny micro cameras that are so often used on the sub-200 quads so I designed a realiable, sturdy yet lightweight angled mount for a 25x25mm camera such as the HS1177.
The camera can be angled up to 25 degrees.
The mount is attached using two M3 screws and nuts. It is dimensioned to fit the larger nylon nuts as well.
EDIT: I've added a more lightweight version model which doesn't protect the camera as well but might be 1.5g lighter.
EDIT: I've enlargened the mount to better protect the camera and also increased the maximum angle to 30 degrees.
EDIT: I've added a new variant of the open mount which is lighter yet still as durable.
