Viper X210 FPV Quadcopter Frame

Prints (1)


This is a frame for a freestyle/racing sized quadcopter. It is designed to be an insanely fast, lightweigth and aerodynamic frame, while still enduring hard crashes. The frame can be printed without support on 200mm*200mm printbeds. It fits standard 2205/2204 motors and electronics with 30.5mm mounting hole spacing, making it compatible with most racing quadcopter equipment. It is an updated version of my 190 frame, with a stronger pod that doesn't break as easily. The weight of the frame is under 100 grams with my print settings (baseframe 75g + pod 20g)

This part needs to be printed in a strong and rigid material. While PLA will work, it’s brittle and will snap on very hard crashes, but otherwise the quadcopter will fly well. ABS, what I have used, works really well, other materials worth considering are PETG, nylon or polycarbonate if you can print those.

If you are printing ABS, acetone smoothing is highly recommendable. It increases the strengthening of layer bonds via the reduction of 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 60% triangular infill, with 3 shells, top, and bottom layers for maximum strength.


This part would ideally be printed with a flexible material like TPU or TPE, but I don’t have that and printed it in PLA. That has worked well so far. You need support for the screw holders, and these needs to be added manually to not get support structure all over the part, as this is not needed. Use meshmixer if your slicer doesn't support manual support.

This is the parts I would recommend if you want to enter the world of miniquads on a budget.

Motors: BR2205S-2300KV

ESCs: RS20A-V2

Flight controller: Naze 32

PDB: Matek PDB

Propellers: Racerstar 5042 3 Blade

Nylon spacer screws

Battery straps

FPV Gear

You can fly the quadcopter without the fpv gear, but it is highly recommended to use it.

Camera: I have 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


For a transmitter I would recommend getting a Taranis X9D PLUS, it's a fantastic transmitter that you can use for years. If you have a tight budget, get the FS i6, or the Turnigy Evolution

4s batteries are absolutely recommended, the Infinity Graphene are great and cheap.
