Viper X210 FPV Quadcopter Frame

thingiverse

This is a frame for a freestyle/racing-sized quadcopter designed to deliver incredibly fast flight times while staying lightweight and aerodynamic, all while withstanding even the toughest crashes. The design allows it to be printed without supports on standard 200mm x 200mm printbeds, making it compatible with most racing quadcopter equipment. It fits standard 2205/2204 motors and electronics with 30.5mm mounting hole spacing. The updated version of my 190 frame features a stronger pod that resists breakage even in extreme crashes. The weight of the frame comes in at under 100 grams, thanks to my optimized print settings (baseframe: 75g + pod: 20g). Maiden Flight Print Settings Printer: P802M Rafts: None Resolution: 0.2mm Infill: 60% Notes: Baseframe This part requires a strong and rigid material to print effectively. While PLA can work, it's brittle and prone to snapping under heavy impact, but the quadcopter will still fly well otherwise. ABS is an excellent choice; other materials worth considering include PETG, nylon, or polycarbonate if you have access to them. When printing with ABS, acetone smoothing is highly recommended as it increases layer bonding strength by reducing surface stress concentrations. I didn't have a large enough container for smoothing the frame, so I painted on a mixture of acetone and ABS plastic instead. I used 60% triangular infill with three shells and top and bottom layers to maximize strength. Aero Pod Ideally, this part should be printed with a flexible material like TPU or TPE, but since that's not an option for me, I printed it in PLA. So far, it has worked well, albeit requiring manual support addition for the screw holders due to the complexity of the design. Example Parts For those looking to get into the world of miniquads without breaking the bank, here are some parts I recommend: Motors: BR2205S-2300KV ESCs: RS20A 4in1 Flight Controller: Betaflight F4 clone Vreg: Diatone 12V BEC Propellers: Racerstar 5042 3 Blade Nylon Spacer Screws Battery Straps FPV Gear While the quadcopter can fly without FPV gear, I highly recommend using it. Here's what you'll need: Camera: The pod is designed for the RunCam PZ0420M camera. VTX: Eachine ET526 5.8G 40CH 25mW-200mW-600mW Switchable FPV Transmitter Antenna: Aomway 5.8GHz FPV 4 Leaf Clover AV Transmission RHCP Antenna Misc For a transmitter, I recommend getting the Taranis X9D PLUS - it's an excellent choice that will serve you well for years to come. If budget is tight, consider the FS i6 or Turnigy Evolution instead. Regarding batteries, I strongly advise using 4s batteries; the Infinity Graphene are an excellent and affordable option.
