Viper X190 FPV Quadcopter Frame

thingiverse

UPDATE: I highly recommend printing the new and improved version 220 of this frame. This is a frame for a freestyle/racing-sized quadcopter designed to be incredibly fast, lightweight, and aerodynamic while still withstanding tough crashes. The frame can be printed without support on standard 200mm*200mm printbeds. It fits most racing quadcopter equipment with standard 2205/2204 motors and electronics that have 30.5mm mounting hole spacing. Print Settings: Printer Brand: RepRap Printer: P802M Resolution: 0.2 Infill: 95% Notes: Baseframe This part needs to be printed in a strong and rigid material. While PLA will work, it's brittle and may snap on very hard crashes, but otherwise the quadcopter will fly well. ABS works really well, as I've used it. Other materials worth considering are PETG, nylon, or polycarbonate if you can print those. If you're printing with ABS, acetone smoothing is highly recommended. It increases the strengthening of layer bonds by reducing surface stress concentrations. I didn't have a large enough container to smooth the frame, so I painted on a mixture of acetone and ABS plastic. I used 95% triangular infill with five shells and top and bottom layers for maximum strength. Aeropod This part would ideally be printed with a flexible material like TPU or TPE. However, I don't have that option, so I printed it in PLA, which has worked well so far. You need to add support for the screw holders manually to avoid getting support structure all over the part. Example parts These are the parts I would recommend if you want to enter the world of miniquads on a budget: Motors: BR2205-2300KV ESCs: RS20A-V2 Flight controller: Naze 32 PDB: Matek PDB Propellers: Kingkong-5040-5x4x3-3-Blade Nylon spacer screws Battery straps FPV Gear You can fly the quadcopter without the fpv gear, but it's highly recommended to use it. Camera: I've designed the pod for the RunCam PZ0420M camera. VTX: Eachine ET526 5.8G 40CH 25mW200mW600mW Switchable FPV Transmitter Antenna: Aomway 5.8GHz FPV 4 Leaf Clover AV Transmission RHCP Antenna Misc For a transmitter, I would recommend getting a Taranis X9D PLUS. It's an excellent transmitter that you can use for years. If you have a tight budget, get the FS i6, but you'll most likely want something better pretty soon. 4s batteries are absolutely recommended. The Infinity Graphene batteries are great and cheap.
