I used endoscope to show you an interiour and view from the submarine. Very amazing!
Here is my modification of HL Hunley submarine kit from Cottage Industry Models.
Total length of 80cm (hull is of 55cm).
According to the kit guidance, I’ve made movable air pipes and horizontal planes. In addition to the kit replica, I’ve made propeller able to be turned from hand crank as it was designed for original submarine. Also, I’ve modified the model so that the rudder can be operated using a tiller, control rod, steering linkage and sliding bracket. Both tanks where water was filled in were painted in blue.
