New Modular Cameras - Olympus AIR (A01) and Vivitar IU680

The latest trend in camera products - modular cameras - is good news for us as drone users.

With Sony releasing products such as the QX100 and QX1 it seemed like high quality alternatives to the gopro we're becoming available.

Now with Olympus and soon Vivitar being the latest companies to add their own modular camera to the list, it looks like 2016 will be an interesting year for modular camera technology.

Here is a…

Balancing Carbon Fiber Props : The Right Way!

Propellers are to a multirotor what tyres are to a car - a key component. Because of this, it pays to get good quality props especially for those who are into aerial video.…


A DIY Magnetic Prop Balancer!

Posted on May 7, 2014 at 12:01pm 10 Comments

In my zeal to get started on my first multirotor I forgot to add a prop balancer to my cart! So I set out to make my own out of parts I had laying around...

My first prototype used a wooden drill bit because it fitted my prop perfectly at 6mm in diameter. Unfortunately because of the shape of the drill bit it would tend to one side, rendering any balancing done…

Hi Jethro,

I am wondering which configuration for an octo is the more stable and manoeuvrable: octo X ou Octo plus.

Have you an answer or could you help me to go in touch with someboby knowing the answer?

Thanks  for your help

Hi Jean,

This is a question which I am trying to answer my self, I am unsure because I am yet to recieve my Ardupilot Board. Personally, I don't think there should be a difference as the arms are close together.

Thanks Jethro,

Sorry for my very poor english.

If you find an answer, please contact me. In fact, I guess that with octo X, momentum are more balanced (more symetrical relative to the deplacement axis). But, before reflecting about that, I began the building an octo plus. So, I will continue my Octo plus.

Hi Jethro,

There are instructions for posting images for Wiki access on the top of the Documentation Editors group we belong to.

If you wouldn't mind I would appreciate it if you would either upload your images to that site and let me know the names of them so I can insert them in to appropriate Wiki Documents or if you have difficulty with that you could EMail them to me as attachments at:

Or if you feel like it you could certainly track down the best Wiki locations for them to be located in and insert them yourself.

I really think they ought to be used, a lot of confusion and unnecessary questions could be avoided (and they look really great).
