MicroQuadie

thingiverse

This 118mm sized Camera Micro Quad is designed to utilize 8.5x20mm Brushed motors, featuring propellers up to 65mm in size. (56mm props are shown in the picture) It is engineered to support the Micro 32bits F3 Brushed Flight Control Board, which can be purchased from Banggood. This motor holder design provides a firm grip on the motors, ensuring they won't slip and protecting the motor wires. The frame and top are kept together with small rubber bands, simplifying assembly. It flies well with BetaFlight. Have fun!

It's not cheap, but I highly recommend it because it is incredibly strong and bends rather than breaks. It's also very easy to print with. Use the photos for reference of my assembly description. Motor mounting Cut a piece of thin double adhesive tape about 5x5mm in size. Stick the tape to the inside of the motor holder on the frame. (See picture) Mount the motor so that the motor bottom is flush with the frame underside. The motor should be turned, so the wires are oriented as in the picture. This way, the fragile motor wires will be well protected from crashes. Slide a cable-tie into the hole of the motor mount as shown in the picture. Place the motor protector on the motor. Tighten the cable tie as much as you can without breaking the cable tie. Cut away excessive cable tie. Electronics Mount the flight controller in the frame using double sided foam tape. It should fit snugly between the corner supports. Slide the camera in place in the top part and secure it with a bit of hot glue. Mount the video transmitter using double sided tape. I use a whip antenna inspired from this excellent description: https://oscarliang.com/make-simple-whip-antenna-5-8ghz-linear-polo/ Use a receiver of your own choice. I currently don't have one that I'd recommend, though I'm currently waiting for this type, to which I have high expectations: http://www.frsky-rc.com/product/pro.php?pro_id=169 Keep the top and the frame together with tiny hair rubber bands. Mount the battery on the underside of the frame using rubber bands.
