Tiny FPV Hovercraft (2"/50mm prop, 1106 Motor, high speed)

thingiverse

Demonstration and how to build: https://youtu.be/IR8SZbQjCBs Small hovercraft designed for 1106 or 1104 brushless motors and 2" 50mm propellers. It was built to be stable at high speeds with the right skirt and to print on a 200mm bed printer. With a 3s lipo and a smooth surface, this hovercraft will be very fast. All electronics should be taped inside. Any wires going out to the top should go through the back where the "back door" file will provide a seal which can be cut for your cables and inserted into the back gap. The rudder and back motor assembly should be inserted and glued into the notches in the back of the main top plate. The rudder is either screwed or glued onto the servo horn. For additional style and stability, a 50mm prop guard can be used like on the picture. A 50mm propguard from the picture might still be found somewhere or something else should fit. If everything should be printed and no propguard is available: The top was updated with a smaller propeller hole for use without the propguard and a rear motor holder with included stiffening parts without the propguard. The skirt should be sandwiched between the top and bottom part. Screws can either be put through the skirt or if it is large enough under the skirt. It should be a flexible plastic foil. Experiment with different materials. Some might not work at all if it is too stiff and can't make a good seal. I found out some trash bags or painters foil work well. Some adjustment might be needed. The small bottom frame is used to surround the center hole and hold the skirt in place. This part should be open and will allow the air to exit and create the uplift. Parts needed: 9g servo for back rudder, 2x 1106 Motor (https://www.banggood.com/de/Realacc-Orange85-FPV-Racer-Spare-Part-1106-6000KV-1-3S-Brushless-Motor-p-1145516.html?p=6F02122925841201511N), 2x small 10A esc, 1x Receiver (3 channel+). I used this one: https://www.banggood.com/de/2_4G-8CH-D8-Mini-FrSky-Compatibel-Receiver-With-PWM-PPM-SBUS-Output-p-1140478.html?p=6F02122925841201511N, 1x buck regulator 5v for servo and receiver: https://www.banggood.com/de/5Pcs-Mini-DC-Adjustable-Power-Supply-Buck-Module-Step-Down-Module-p-952402.html?p=6F02122925841201511N, 4x small 2mm wood screws for bottom frame, 10x 3mm large screws, Flexible plastic foil/bag. Cut around 10cm larger than the bottom, experiment with different materials. If you don't have the 50mm propguards from the picture: print the "no propguard" versions of the base and rear models.
