Hi guys. My talented friend Gong Shuang wants to share this easy-to-print, easy-to-build and affordable RC Speed Boat with you all. Watch the video: www.youtube.com/watch?v=ptFTwXCmMQk For printing, infill can be set at any level except for two parts that require specific settings: 1. Front hull - use a low infill setting of 1-5% 2. Motor mount - use a high infill setting with a minimum of 50% Layer settings should be at least 3. The hull should be printed upright. To prevent overheating, add a high heat tolerance spacer between the motor and motor mount or a piece of sandpaper to protect the 3D printed part. This boat can be built for around USD30 (not including Lipo and Remote) or just USD7 for the shaft and propeller if you use mostly spare parts from RC planes. The dimensions are as follows: Length: 350mm Here is the list of required parts: Shaft (get a 13cm one): https://www.banggood.com/Stainless-Steel-8mm4mm-Marine-Prop-Shafts-For-RC-Boat-p-934428.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P Propeller (drill a 4mm hole): https://www.banggood.com/Two-Blade-RC-Boat-Screw-Propeller-P40D273032353840424547mm-p-976294.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P Universal Joint (get 3.17*4): https://www.banggood.com/Metal-Universal-Joint-For-RC-Cars-Boats-p-87379.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P XXD 2212 2200kv Brushless motor: https://www.banggood.com/XXD-A2212-KV2200-Brushless-Motor-H365-For-RC-Airplane-Quadcopter-p-909081.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P Emax 9g Metal Servo: https://www.banggood.com/EMAX-ES08MA-II-12g-Mini-Metal-Gear-Analog-Servo-for-RC-Model-p-935479.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P 1-way 30A ESC or a 2-way depending on your radio: https://www.banggood.com/Wholesale-XXD-HW30A-30A-Brushless-Motor-ESC-For-Airplane-Quadcopter-p-50621.html?utm_campaign=t0002_1123036&utm_content=11033&p=DG23031123036201501P
