Update the mounts for the rudder, they were not stiff enough, as well as the mount for the motor, also optimized the cooling for the motor. You need to print every part once, except for the skids (Sumpfboot_Kufe_xxx) those you need 2 of each and click them together with the dove tails (could not make them as one piece, because my printbed is only 200x200 mm). Other parts you need: 14 x locking nuts M3 (insert them into the bottom side of the mounting plate), 14 x washers for M3 bolts, 12 x M3x12 bolts (rudermount + motor), 4 x M3x10 bolts (motor mount), 2 x M3x8 bolts (servo mount), 6 x locking nuts M2.5, 7 x washers for M2.5 bolts (the 7th one is for mounting the servo onto the guide), 6 x M2.5x8 bolts. You will also need 1 x Motor Multistar Elite 2204-2300KV (that is the one, for which the holes on the motor mount fit) https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=70353, 1 x fitting ESC for the motor: I used this one https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=47810, 1 x propeller 6x4 or 6x4.5 https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=91765, 1 x Servo Towerpro MG90S Metal Gear RC Micro Servo http://www.banggood.com/4-X-Towerpro-MG90S-Metal-Gear-RC-Micro-Servo-p-961967.html, 1 x battery 3s, mine is a 3s5p, made out of 18650 cells from Panasonic with a custom holder (Dimensions 100x65x72 mm), if you use any other battery, you need to make a custom cover and mill a different hole into the hull. You will also need 1 x remote control + receiver and 1 x hull: I made mine out of a PUR (polyurethane) foam insulating wall panel, after cutting and sanding it was 500x300x50 mm with a suitable form, bow, etc. (should look like a swampboat), before cutting the bow, attached the skids temporarily to get the proper angle for the bow. You also need to cut and/or mill the holes for battery, rudder_base, cableguides and the propguard into the hull (you need to check for balance a couple of times, basically put the hull in the bathtub or something similar and put the parts on top, you should look for a trim with little more weight to the stern). Print the parts first and put them on the hull to get the correct dimensions. At last you should cover the hull with glass fibre and epoxy to get it waterproof. I haven't finished mine yet, but I will provide more pictures of the finished boat.
