Brushless Micro Quadcopter

Here are the parts I used: Motors: https://www.banggood.com/4X-Racerstar-Racing-Edition-1103-BR1103B-10000KV-1-3S-Brushless-Motor-Black-For-50-80-100-Mini-Frame-p-1133949.html - Be careful with the motor wires, they tend to break very easily. Propeller: https://www.banggood.com/10-Pairs-Racerstar-2435-60mm-4-Blade-Propeller-1_5mm-Hole-For-11xx-Motors-80-110-FPV-Racing-Frame-p-1137453.html - Camera/VTX combo: https://www.banggood.com/Eachine-TX02-Super-Mini-AIO-5_8G-40CH-200mW-VTX-600TVL-14-Cmos-FPV-Camera-p-1088368.html - I think, the newer TX03 should fit as well? Flight Controller: https://www.banggood.com/Eachine-Minicube-20x20mm-Compatible-Frsky-Flysky-DSM-RX-F3-Blheli_S-10A-For-Aurora-68-90-100-Lizard95-p-1127223.html - Any other controller with 20x20mm mount should also fit. DC/DC Converter for camera: https://www.aliexpress.com/item/5pcs-Mini-DC-DC-12-24V-To-5V-3A-Step-Down-Power-Supply-Module-Voltage-Buck/32758763577.html - You need to cut the copper bridge at the 'Adj.' position and solder a bridge at the '5V' position. Battery: http://www.mylipo.de/Lipo-650mAh-74V-50C-100C-FPV-Parcour I printed many prototypes with this filament: https://www.hta3d.com/en/filament/pla-1.75mm/pla-filament-easy-printing-175mm-all-colors-materials-3d-1kg-ingeo-3d850 - I can really recommend it, it's the best improved PLA I ever used. It seems to be even stronger than ABS! My print settings: Layer 0.15mm, 205°C nozzle, 70°C bed. No support needed. Use a little bit of CA for gluing both pieces together. I also took pieces of filament to build a simple protector for the Flight Controller and a guide for the antenna. The camera and the DC/DC Converter will be attached with small cable ties. The battery will be fixated with a small rubber ring, hooked into the battery mount. Takeoff weight should be little above 100g. I'm aware that this isn't the lightest micro quad, but for my needs and abilities it performs very well.
