Motor Boat RC enlarged (experimental)

thingiverse

This simple enlargement method makes the boat large enough to accommodate a powerful outrunner motor used in an airplane. The 100mm extension is printed and attached between the bow and stern parts using tape. Initially, a friend's surface propeller was tested, proving more effective than a printed one. However, control issues led to the preference of the printed propeller, which creates more noise but allows for better control. At higher speeds, the boat's bow lifts, creating a large bow wave that can splash water. To combat this, weight must be shifted forward, even maximizing it in some cases. The video quality is regrettably poor, despite attempts to upload it at different sizes. Ducks were unimpressed with the boat. For printing, use spiral vase method for a neat surface and print hulls 3mm thick with layer height of 0.3mm and width of 0.6mm. Interfaces are designed for easy alignment and gluing. The boat is intended for Roxxy BL-Outrunner motor, requires a driving shaft and coupling made of 3mm rod and heat shrink tubes, respectively. Surface propeller needs an M4 to M3 adapter and should be shortened. Additional parts can be found at the given Thingiverse link.
