DescriptionMy 80mm design water jet thruster for bigger rc boats, kayaks, jet surf, small boat.. Great design with big steering angle, low drag for maximum water flow, high or low angle of attack impeller (two options). It offers great water cooling system for motor and esc (you dont need additional water pump). Shaft seats on 3 bearings for better stability. With brass inserts which are inserted very easily using soldering iron. You can choose between normal difusor or steering difusor. Walls are 3mm thick and this makes it very robust design. Easy to print (hard parts with PLA and gaskets with flexible filament). All you need to assemble it is: -3x skateboard bearing (8mm ID, 22mm OD, 7mm thickness), -2x lip seal (same dimension as bearing), -13x-7mm M4 brass threaded insert, -8x M4 bolt, -2x m4 nut, -2x kniping screw, -2x brass hose barb fitting for water cooling- 10mm thread, -1x 250mm long shaft 8mm thick with 70mm thread at one end, -1x M8 nut which is inserted in impeller while printing process. You will need 7mm thick M8 nut for 3 blade impeller, and 24mm thick M8 nut for 6 blade impeller. You can check demonstration video of this jet unit here (in this video i used only 6s battery). Tips: Impeller- first calculate time for printing not completed impeller. This is the time you will hit pause button and stop printing complete impeller. In that time you have to insert M8 nut inside (it is tight fit. If its to tight, use soldering iron to heat the nut to press it in easily). When the nut is in, just continue printing. If possible use reinforced PLA for making impellers. Bearings and lip seal- just press them inside (first bearing, then lip seal) Shaft- needs to be as straight as possible. Any vibration will cause bearings to heat. Its best if its made of inox. Infill for all the hard parts: 100% Infill for seals: 15% Supports: dont need them for: impellers and gaskets Layer hight: 0.2-0.3mm ( on picture is printed with 0.3mm) Temp: PLA 205C, Flex 230C If you are interested in finished product you can get it on our official website. We offer much improved jet pumps of size 80mm and large 100mm version. Both offer much more power than this pump. ** Jetx-80V3 demonstration video:** https://youtube.com/shorts/bgK93VX-U5Q?feature=share JetX-100V2 demonstration video: https://youtu.be/wIYQqkqNang https://youtube.com/shorts/FIrxqD0FED8?feature=share *JetX-100V2 steering system deomnstration video: * https://youtu.be/hbXR6C-6q_c *Official website: * https://ma-3d.com/ *Jet thruster store: * https://ma-3d.com/product-category/propulsion-systems/water-thrusters/waterjetpropulsionunithamiltonpumpthrusterrcboatsteeringkayakelectricsurfpowerfulspeedjetskihobbydiyspeed boatmechanical partshobby diymechanicalparts
