Building a FPV racing drone Part 1:

I remember the first time I tried on a pair of FPV goggles and took my drone for a spin. At that moment what I felt was incredible. I true out of body experience. My mind ran wild thinking how I could do this in 3d and increase the quality. I could see this being a game changer in the future of entertainment. So I had to build on for myself. I usually fly dji phantom 1 which is has so many add-ons that it looks like a Frankenstein. Also its flight time is down to merely 6 minutes with all the added weight.  So I decided to build something smaller and a bit more nimble. I’m going to be using off the shelf components and maybe a 3d printed part here or there.

Let’s start with the bill of materials

[Qty. 1] Super Simple Mini H-Quad FPV V3 Frame

[Qty. 1] CC3D Flight Controller

[Qty. 2] APC 5545E Electric Prop {or} 5030 Prop

[Qty. 2] APC 5545EP Electric Prop {or} 5030R Prop

[Qty. 1] 36mm Power Distribution Board

[Qty. 1] 1800mAh 3S 40C LiPo

[Qty. 1] XT60 Connector Pair

[Qty. 12] M2x12mm Bolt

[Qty. 4] Tiger MN-1806 2300KV Motors

[Qty. 4] Afro 12A SimonK ESC

[Qty. 4] M3x6mm+6mm Nylon Spacer

[Qty. 4] M3x8mm Nylon Screw

[Qty. 4] M3 Nylon Nut

[Qty.~] Cable Ties

[Qty.~] 16AWG Red Wire

[Qty.~] 16AWG Black Wire

[Qty. 1] Sony Super HAD CCD 660TVL Camera

This is an awesome list from Polakiumengineering so kudos to them. They have a really nice 3d printed acetone treated frame which looks pretty nice. You could of course print one yourself but you would need a pretty large bed 3dprinter.

If you noticed there isn’t a receiver and transmitter in this list. I’ll be looking to get a Spektrum DX6i transmitter with a DXM compatible receiver. I haven’ purchased these yet so look forward to my second post for more details there.

One more note is the FPV goggles. Fatshark is the de facto fpv goggles. Though oculus and other VR alternatives are nice concepts they really don’t play well with FPV thus far. The portability aspect of fatshark and the built in receiver makes them very practice. I own a Predator model which comes with a transmitter (http://fatshark.com/ )

Moving on to construction the first bit was simply attaching the motors to the frame which only took a few minutes.

Be very carefull when doing this! if you screw the screws in too tight they can damage your motors
I recommend using a plier to shorten your screws as I lost 2 motors due to screwing them in too tight. You have been warned.

Now comes the fun part. I’ll be putting on the ESC’s which control the power which flows in each motor. I’m also excited to try out some of my own 3d printed parts for this project. As there might be opportunities to shed weight while affecting performance in the most minimal way.
