This appears to be a detailed report from an RC enthusiast who has designed and printed their own jet boat using a 3D printer. The report covers various aspects of the design, printing, and testing process. **Test Setup** The writer has conducted two tests with different ESCs (Electronic Speed Controllers) and LiPo batteries: 1. Test 1: MagiDeal 2598 4200KV Brushless Motor & Waterproof 70A ESC 2. Test 2: Dynamite 120A BL Marine ESC 2-6S Single Connector, DYNM3876 The writer has also tested two different LiPo batteries: 1. Turnigy Nano-tech Shorty 4200mah 2S2P 65~130C 2. GNB RC Battery 7.6V 5600mAh Shorty 2S LiPo LiHV Battery 100C~200C **Design and Printing** The writer has designed the jet boat using a 3D printer, with most parts printed at 3 perimeters and default infills of 15% Grid pattern. They have used PLA or PETG as the printing material, and ASA for its waterproof properties. The writer has made several design changes to improve the water-tightness of the boat: * Flattened the mating surface on the top lid * Thickened up areas around bolt holes * Added a flat rubber gasket for the deck lid seal * Changed the servo position for better direct drive **Propeller Design** The writer has designed a custom propeller with a special locking collar and shaft modifications to fit the boat's tunnel. **Future Edits** The writer plans to make additional edits in the future, including: * Adding threaded inserts where the lid bolts attach * Increasing the clearance between the haul and the lid * Possibly adding additional bolts to improve water-tightness Overall, this report provides a detailed overview of the design, printing, and testing process for an RC jet boat. The writer has made several changes to improve the performance and durability of the boat, and plans to continue making edits in the future.
