Supplies needed: 1/2 inch section on conduit 3/4 section of conduit 1000KV RC motor I have included two motor mounts for this project, but have only built one variation, and thus the motor shroud for the smaller motor mount was not designed. I used an old burned out 100KV RC motor for the bearing case of the hub. I have not attempted to generate electricity from this design, but I imagine it could be possible using either a gear reduction, or belt, and pulley design. To assemble: install the brushless motor to the mount, and glue into the end of the 1/2 inch conduit. assemble propeller blades to hub, and set aside ( I used 3/16in screws) - I used the stock propeller shaft mount that came from this motor to clamp the shroud, and the hub together, additional spacers may be required to ensure the propeller mount clamps to the shaft of the motor. (1000kv motor shown in photo) - these are relatively cheap on ebay, There is a mount for use with a smaller quadcopter motor that has not been tested. When cutting the length of the horizontal pivot it should be longer than 12 inches, it's also important to leave the horizontal free from glue until all parts are installed, and you can find the center of gravity, which is important for the windmill to seek the direcion of the wind - typically the longer the better. my example is 18 inches long. The 1/2 inch conduit is fed through the horizontal pivot, and was slid through (not snapped into place) all attempts of snapping it into place resulted in failure. Mount fin to fin mount (of your choice) to the opposite end of the motor, there are holes for screws (which I've opted for) or simply glue into place. BEFORE GLUING- ensure that the center of gravity resides on the center of the horizontal pivot, and mark its location on the shaft. glue motor mount, and fin mount into place (may need to remove propeller once center of gravity is established, for easier gluing) Then glue the 3/4 inch conduit to the vertical part of the horizontal pivot. Glue the horizontal pivot into place at the same 90 degree angle as the fin. Glue support pole pivot into the 1/2 inch, and slide the entire windmill assembly over the pivot JOB DONE!
