Anyone know if the Alexmos controller would work with the above product? I'd gladly pay the 450 for the rig and 100-150 for the controller.

This is the alexmos controller you want for 3-axis http://www.armbgc.com/armbgc-v3-0-alexmos-controller-3-axis/ Still waiting for him to design a 3-axis in one board though. The video of the 5-axis is blowing my mind. The guy's a genius and should be designing and releasing camera rigs.

@kevin_kirchman let us know if you take the plunge, I look forward to seeing your results. I've been playing around with a small 2 axis gimble with my nex5n and the alexmos firmware to get my head around how it works. Turns out its not too complicated. Alexmos is definitely the best option out there right now in regards to ease of tuning and results.

I'm on a 10 day shoot in Austria with the BMCC, and had the opportunity to try out the Portahead 2 gimbal mount. I'm pleased with the results -- some lovely smooth footage, although since it was a prototype, there were some issues with drift in the remote control that need correction.

Generally, once the camera is balanced, then the gimbals support it very well, but getting the balance right takes two people nearly 30 minutes, so it eats into the production budget.

The Portahead 2 supports 2 kg, which means the BMCC and a Voigtlander f0.95 lens. The team from Portahead were extremely helpful, and drove all the way from Germany for two days to set up the rig for us, and give us a chance to try it in a real life production environment. Note this is not a full review, as my chances to use it have been limited, but I have high hopes this will be a great tool for future film work.

** EDIT: Added picture of my regular 1st AC using the rig.

I've been doing my research. I'm going to build one. I ordered a 5010-360kv motor to test. I will rewing the motor. I wish Martinez and Alex Mos had 3 axis single boards designed already. I've been looking at the Evvbg board which is 3 axis. Has a better microcontroller. And I've seen footage where both the Martinez and Evvbg are running Alex Mos firmware.

I do think the virticle axis is needed. That is the major benefit of a real steadycam. The arm absorbs the up and down motion of walking or running.

Since I will only be using it with a GH-2, I'm thinking of downscaling the rig. I don't hava a controller yet, but I will report back on my progress.

Did anyone test this kit as a starting point ? http://www.uuustore.com/mastorhx-twoaxis-brushless-gimbal-ptz-camera-mount-set-for-gh3-gh2-5n-nex7-camera-aerial-photography-p-1831.html It look well made, better than the falcon's and ok for a gh3 ... I know it's a 2 ways but it may fits my needs (a shoulder mounted rig like the Tom Antos one, so I want it to pan with me !)

What's your solution for the remote HDMI monitoring?

You can check topics about WHDI - http://www.personal-view.com/talks/discussion/1134/wireless-hdmi-connection-whdi-options#Item_12

It is cheapest option for monitoring without lags. But range can be limited.
