Quadcopter FPV 250 Building

thingiverse

This is a quadcopter FPV 250 build, and I've spent considerable time on it. I'll share my quadcopter build experiences with you. Before building a quadcopter, it's essential to have some quadcopter knowledge and prepare the necessary materials. Here are my quadcopter 250 materials and the step-by-step guide to building this quad. Designing This Quad To begin, I need to choose the right frame for my quadcopter. I've opted for a HobbyKing/Diatone 250mm FPV "Long" frame (FPV250L). Next, I'll assemble the flight control system using a HobbyKing KK2.1.5 Mini flight controller. Quadcopter FPV 250 Materials Here's what I need: * HobbyKing/Diatone 250mm FPV "Long" frame (FPV250L) * HobbyKing KK2.1.5 Mini flight control * Emax MT2204 Motor/Prop/ESC set with the TATTU 30A BLHeli_S ESC * Tattu 1300mah 4S lipo battery * Matek mini PDB (I need a BEC power source, so I'll use this) * Assorted cabling bits to link the yet-to-be-bought receiver to the flight controller * Programmer to suit the KK2.1.5 so I can flash on the newest firmware etc * XT60 adapter to get my old battery charger (LiPo) up and running The Frame I've chosen a HobbyKing/Diatone 250mm FPV "Long" frame (FPV250L). This frame is designed for long-range flights and provides excellent stability. It's also easy to assemble, which is perfect for beginners. Wiring the Quadcopter To begin wiring my quadcopter, I need to strip off the heat shrink so I can de-solder the signal wires - only 2 as my ESCs are Opto. By customising their length at this end, I don't need to play with new connectors at the F/C end. Next, I'll mount my Matek PDB to the underside of the "X" section using 3M Automotive DS Tape. It's not going to fall off! In this pic, you can see I've biased it rear wards and soldered two of the ESC power feeds on. The ESC wires are trimmed to length and protected with heat shrink tube. After that, I'll temporarily mount the F/C on a foam block to let me get the wiring runs the way I wanted. If it's not obvious yet, I'm also mounting the ESCs on the underside of the arms (there's shallow recesses in the arm for this). Tying Up Loose Ends Now that everything has a place, I'll re-heatshrunk the ESCs, cable tie the wiring runs on the arms, and generally tidy up. The ESCs are DS taped into the recess, wiring held with cable ties at each end, and then a loop of tape is used. Final Check I've powered up the unit and rather satisfyingly got some beeps from the Warning buzzer, and a melody of sorts played on Motor - 2. Not sure if that's normal. The F/C could see the correct battery voltage. Overall, I'm really happy with my effort.
