3D Printed RC Brushless Speed Boat

thingiverse

Hey guys. My friend Gong Shuang, who's super talented, wants to share an easy-to-print, easy-to-build, and affordable-to-own RC speed boat with you all. Check out this video: www.youtube.com/watch?v=ptFTwXCmMQk When printing the parts, you can choose any infill percentage you like, except for the following: 1. Front hull - use a low infill of 1-5% 2. Motor mount - use a high infill of at least 50% Layer settings should be at least 3 layers. Print the hull upright. Don't forget to add a high-heat-tolerance spacer between the motor and motor mount, or a piece of sandpaper to prevent overheating the 3D-printed part. If you want to show your appreciation for Gong Shuang's work, just send me a message after sending a tip so I know it's meant for him. Thanks! This boat can be built for around $30 (not including the Lipo and Remote), or you can get away with spending only $7 on the shaft and propeller since we mostly use extra parts from RC planes. The boat is 350mm long. Here are the parts you'll need: Shaft: Get a 13cm one.
