Umma85 - Beta85x Naked GoPro Conversion

thingiverse

I wanted to build smallest drone that can carry a GoPro. It needs to be reliable enough to use on my professional flying gigs, and durable enough to handle an occasional crash or bump. It needed to be able to fly extremely close to people, through tight spaces, or flying in extremely sensitive environments where any larger drone would do some damage if something bad were to happen. So I decased a gopro and got it to a point where it weighs 17g (thanks to the Naked GoPro community). It shouldn't take much to lift this guy, so I went with the smallest RTF out there that had good reviews, the BetaFPV Beta85x. The fact that it has 2" props and flies on 4s should make this not only work great but still be a lot of fun. I went to town modding it, starting with converting it to a pusher configuration (flipping it upside down), which gave me a lot of space up top to relocate and mount things. Knowing that I needed the now 17g GoPro to work with Reelsteady, I needed to ensure that vibrations wouldn't make its way to the GoPros onboard gyro. So I borrowed a chapter out of the Acrobrat book and developed a clean & dirty setup that would utilized the mass of the battery to counter the vibrations from the drone. What you see/get out of this kit, is a few weeks of development and testing, but the result speaks for itself. The top mounted battery design along with the clean section makes for the smoothest and cleanest footage that works exceptionally well with Reelsteady. I've also made sure that it works with readily available ND filters. The design uses the minimal amount of parts and hardware to make the clean section work all while maintaining a crashability factor. https://youtu.be/v9eaMN6Jntk https://youtu.be/fCBV3PbjzH8 https://youtu.be/CV31zBsxsCU Big thanks to the community members of the Naked GoPro Facebook group who helped immensely this project. Here's the non-printed parts list: 1 - 1mm Carbon Top Plate 6 - M2x6mm Self Tapping Screws 1 - M2x12mm Self Tapping Screw 4 - M2x5mm Machine Screws All parts are printed in TPU and the DXF is provided for the carbon plate. The recommended hardware is self tapping M2 wood/plastic screws. EDIT: I've re-uploaded the files with easier to understand file names, updated a few of the files to add some small improvements. 1. We updated the clean plate to allow for the HDMI connector to remain in place. In the previous design it was required to remove the HDMI connector from the board, but some found that difficult to do. After another issue was found, we updated it again, to ensure the easiest route for the cameras ribbon cable. 2. We tried to update the GoPro camera mount to allow any camera protection on the fpv cam to remain out of view... but... it put too much stress on the ribbon cable when using the updated clean plate. So... we removed that camera mount and have reserved it for use on the umma95 where it needs to keep the DJI camera out of view. 3. Some people have noted that their TPU is too soft to use the existing vibration isolators. We have added a thicker isolator, as well as a longer isolator to hopefully work better with softer filaments.
