I see a lot of people here are interested in more affordable knockoffs of the standard-issue ruggedized action cam. Check this one out, it has similar specs to a GoPro Hero+, and it's only $160 (or $200 with a watch controller):

depending on card support size and if it will work with the gimbal for the Solo 3DR, this could be a nice option.
You can view the screen on the watch? sweet.
