2inch FPV drone

Fully 3D printed frame that I designed for a 2inch fpv drone.

I wanted the drone to by fast while still being small and light.

The drone weights well under 250g with battery.

The frame is inspired by Flywhoo Firefly 2s nano baby 20.

I reused all parts from another fpv drone: Happymodel Cine8, so I didnt have to buy anything new!

But the drone can be definitely build from standart parts as well and maybe it will fly even better.

The canopy used for this drone is also 3D printed and can be found here:

Any canopy with 25x25mm mounting that fits your camera can be used.\

I also include small 3D printable spacers for mounting the VTX.

If you want to make any changes to the model .step file is also included :)

PARTS:

4x 1202.5 8000kv-brushless motor (11xx motor will be more enough)

1x Crazybee 2-4S AIO F411 + 12A ESC (any AIO with 25x25mm mounting can be used)

1x VTX OVX306 25-400mW

1x Camera Caddx Ant 

1x 450mAh 3s lipo battery 

1x radio receiver (if you dont have AIO with build in receiver)

4x 2inch 2blade props (i use Gemfan Hurricane 2015-2)

1x 15mm wide battery strap (you need a pretty short one)

HARDWARE:

4x M2x20mm bolts (the lenght depend on hight of your AIO stack)

4x M2 plastic nut (for securing the AIO)

16x M2x2mm bolts (for mounting the motors)

PRINT TIPS:

The frame has to be as stiff as possible, so i recommend printing it from some carbon fibre filled filament, also rigidity is a key factor because the drone will propably crash from time to time :)

I used Prusament PC Blend Carbon Fiber Black

Use 100% infill and 3 perimeters for maximum stiffness.

Flip the frame so the big holes for bolt heads are on top.

Turn on supports on build plate.

If you have any question about the build you can ask me in the comments.
