Simple Brushless RC Sport Hovercraft

prusaprinters

This is a small sport hovercraft that is simple to build and decently fast and agile.Materials:2x 1407 brushless motors2x 15a brushless ESC2x 3in prop1x 9g servo1x at least 2ch receiver1x battery connector(I used an xt30)1x 3s or 4s lipo about 1000mah1x servo "Y" harness1x plastic trash bag1x velcro or other battery restraintmisc soldering suppliesepoxy, CA, or hot glueTools Required:soldering ironwire cutterswrenchsmall screwdrivercorresponding hex driver for motorsBuilding Instructions:First, print out all pieces and remove any support. Next, glue the rear motor housing in place, it should be very secure. Also, screw in the motors. For the rear motor, route the wires down the hole in the back. For the front motor, zip tie the wires to the underside of the spoke pointing back. (the electronics will be on the bottom) Wire both ESC power leads in parallel going to the battery connector. Solder each motor to its corresponding ESC and check its direction. (if the motor is spinning the wrong way, simply swap any 2 motor wires) plug both ESC receiver connectors into a "Y" harness that goes to the throttle channel on your receiver (the same coupling effect can be achieved with mixes if your radio supports it). If you wish to have the lift motor on a separate channel, don't use the "Y" harness . Take the servo and screw it into the mount in the back with it facing up and the output on the back. Plug your servo into your steering channel. Get any servo horn and cut off the sides. Glue the middle part into the hole in the rudder. Finally, when your servo is centered, screw down the rudder. Next, place a thin bead of hot glue along the inner ring of the skirt frame and glue it to a large piece of trash bag plastic. Cut out a border about 1.5in from the outer ring. Finally, fold and glue the plastic on the top of the outer ring. Cut out the middle of the inside ring. When you are done with the skirt, it should have a pocket running along the inside and the middle empty. Last, when all the electronics are done(they should be mounted to the underside to hovercraft) and the battery connector is poking out the hole in the top, use a glue like hot glue to glue the skirt in place. (it is temporary because the skirts wear out) Add what battery restraint system on top you want and set up your radio. ***Be sure to check out the build video linked in the MAKE below by ValRC***Note: Moving the center of gravity around will change how it turns and handles. Experiment until you find what works best.
