It has been tested on a much used quad with worn bearings, one bent motor axle and no balanced prop, giving a lot of jello with rigid camera mount.
Super Jello Killer effect was clear, there was no more jello.
My previous device, made with rubber bands, was also working well but it was larger and lacking fast setting of camera's angle.
Hoping this could help users of less than perfect multicopters.
