Hi,

I wanted to share with you the build log of my last quadcopter dedicated to low riding and fpv racing.

Goal :

- Less than 500g

- Cheap (less than US$250)

- Powerfull

Flight time is 8-9min with 1300mah battery.

You can view the entire build log on my blog : http://www.dronebench.com/how-to-build-a-fpv-racing-drone-for-us240/

Hi Gotleg,

Great Build article.

I think this is a very good little copter for FPV flying in general, not just racing.

And it's small size and light weight make it safer than the bigger ones.

I'm going to link to it from my dronesarefun.com web site if that is OK with you.

It should be very popular with many of those who would like to make their own, but want a small copter.

And I think small, light, relatively non-dangerous quadcopters are the least likely to be legislated out of existance.

These little guys are the future.

Best Regards,

Gary

The problem with those $50 frames is they break quite easily when one crashes. Not only that but they are quite poor in flight, with problems like vibrations. After you spend hundreds on goggles, cameras, transmitters its plain stupid to try and save $100 and by a cheap frame when you can buy the best or close to it for that bit more.

Also that frame didnt cost under $250, a Mobius is about $70, the video transmitter about $55, that means your buying $5 esc and motors. Your frame is going to be utter junk and you can be sure it will break and cost you lost days as you wait for replacements parts. You dont get much for $100 these days, our time is worth more than that.

Your build log is completely dishonest, how can you not factor in the cost of the receiver and lets assume this is for new users they will also need to purchase a transmitter. You also didnt mention the cost of the goggles or screen to view the live fpv footage.

The true cost is no where near $250.

@Gary McCray : Sure no problem.

@mP1 : I don't agree with you concerning the frames. You can find very good cheap frame. I personnaly crashed some times with this frame and noting broke yet.

Yes it costs me less than $250 and I don't agree with you about the price. If you start from scratch it will cost you more but I thought I was clear at the begining of the post.

@ Gotleg: Do you have any other FC suggestions apart from the two listed. Would an OP CC3D by any good for the purpose? Thanks for taking the time to post your build log.

@Damouav : Yes, I order on CC3D a fiew days ago and I'm really exited to see the result.

I took this one :

OpenPilot released a new version a few weeks ago to improve usage on mini quads so I hope it will perform very well.

@technicus acityone : Yes it is still possible to reduce the bill. I've never tried KK boards.

For the cam I already ordered the FPV cam you indicated to see how it works and also this one :

Wooden frames are also nice and easy to repair.
