jjrc h6c prototype 2 frame

thingiverse

Frame printed with Cura at 0% infill, using a 2mm nozzle width shell thickness and a layer height of 0.2mm, without any support. The motor hole mounts were pressed into place perfectly with the Cura settings, requiring no sanding, although some trim runoff did occur - this may vary depending on the slicer, printer, or other factors involved. To avoid stripping the plastic, screws need to be inserted carefully, especially when using low infill percentages; adjusting the shell thickness will strengthen the mounting holes. Next up is designing a JJRC camera mount that allows users to disconnect the camera completely, ideal for nighttime flights, which I'll accomplish by using an IC socket to connect the camera. To enhance the LCD controller's visibility, I added a surface-mount LED connected in series to a 6V source on the board, which ties into the main on/off switch. This frame was initially tested for aerodynamics and shows promising results; however, its weight, even at 0% infill, is somewhat excessive. In my pursuit of optimizing aerodynamics, I experimented with incorporating the Coanda effect onto a surface - though with this platform's small size, adding extra weight severely impacts overall performance, making it less than optimal. Currently, I'm working on a new frame that balances minimal weight with sufficient rigidity for improved performance.
