ZMR 250 LowRider

There's an updated Version available here: https://www.thingiverse.com/thing:3327180 To build this frame, use bottomplates and arms from an old ZMR250 frame that you no longer need. I wanted easy access to the electronics, so I left the sides open. This way, you can build something that's ready to fly without hassle. You'll need these screws: * M3 30mm: 14-16 * M3 7mm: 4 * M3 10mm: 2 * M3 nyloc-nuts: 18 * M3 nut-standard: 2 One Bottom-plate needs to be cut out in front of the arms, so you can place your camera there. I used a trusty old Runcam Skyplus with a magnesium-case that's 30x30mm. Any big FPV-Cam with a 30x30mm-case will fit. The pins hold the camera in place, and I use two 7-10mm M3 to fix the angle of the camera. There's an alternative hood for a 25mm-FPV-camera. I used my cc3d-atom-enclosure to stack an Matek 5in1 and a cc3d-atom (https://www.thingiverse.com/thing:1684887). There's room enough for a 30.5x30.5 stack, with the RX in front and VTX in the back. What I like about this frame is its low profile and only six carbon parts. The open sides make it easy to connect usb and check electronics. My FPV-cam is fixed firmly in place for rough use. What I don't like is that when using all screws and locknuts for the arms, it's a real pain to remove the upper carbon part to get a hand on the electronics.
