  1. It looks like they're taking a page from the CMotion handbook. The motors look like they are just receiving a serial connection from the wireless receiver. The drivers are probably built into the motors. That means no cross-compatibility.

    Alan,

     

    That is correct. I owned one for awhile and the motor cables were just power and serial, 4 pins.

     

    Originally they were supposed to have a dongle to convert to the 7 pin standard, but they haven't done it yet.

  2. Michael,

    the connector is a FGG.3B.856.CLADXX (where XX is the cable size). But it is not a connector you can do yourself. The coax portions of it are crimp and you need a special tool (as far as I know).

     

    I will post some pictures of it when I get back into town after the holidays.

     

     

    That all being said, I really enjoyed doing the work on my rig to upgrade it to HD. It works and I now know my rig even better. To be fair though, it is a bit of a frankenrig.

  3. Ah, yes. I am actually not very familiar with the Pro bayonet connectors unfortunately.

     

    My top stage uses a 2B 307 connector rather than the 3B 308 connector of the pro. It is smaller and lets me get around the connector.

     

    I think the only way to do that with the newer style is to switch them out to be the 3B 856 style. The issue with drilling out the video conductor is then I think you couldn't take it apart without completely disassembling the HD line.

  4. Well, I have a MKV upper junction box, so it is slightly different in mechanics than the pro 1 or 2. I think the pro 1 rig would be easiest to do at the top since it is hard-wired in. There needed to be a hole in the upper junction box to allow the cable to pass through (and the RP-SMA connector so I can take the rig apart) and the bottom needed to be dremeled out a bit to allow the cable to pass as well. I can take some pictures and post them if you'd like (though my rig is a bit of a frankenrig, so I don't know how much you can glean from them)

     

    I ran the mini-coax around the connector on both the top and bottom. I just heat-shrinked the mini-coax to the outside of the coiled cable the whole way up the post. I think normal sized coax would be too big to fit in the post. Unless you have a 2" post maybe. The cable I used wasn't perfect though. If I did it again I would go with Belden 179DT I think. It is what Alan Rencher uses for some of his mini-BNCs I bought and I really like it for size and flexibility

  5. As far as I know it is not. I believe there are issues with impedance and shielding in the SD wiring (that are perfectly fine for a composite signal) that will not allow it to work with HD. That being said, I have not tried it myself. I did do an HD upgrade, but ran an independent mini-coax down the barrel, connected with RP-SMA connectors. It did require a bit of mechanical modification to make the cable fit through the joints in the rig, but was fairly small and did not harm the integrity of the rig. What rig do you own?

  6. To me peace of mind and awesome customer service is a very high priorities and are worth $1000's when you consider it must work perfectly every time I work .

    Karl is the RT Motion receiver smaller then the BFD Digital receiver ?

    The RTmotion receiver is smaller than the BFD. Not by a ton, but WAY smaller when you realize it does FIZ.

  7. Tommy,

    I have actually all but stopped. I have, thankfully, been working enough that I can't make cables with the expediency needed.

    That being said, if someone is local and needs something quickly because of an issue, if I am off I would be happy to help!

  8. The width very well could be a problem. I will try and grab one from a rental house to try it on a show before I buy one.

    The HCXs or dionic 160s make more sense. Thanks for the tip!

    I hope things are going well, it has been awhile!

  9. I had a job recently that I was wanting for more bottom weight so I wouldn't have to extend my post quite as far (an issue I have run into a couple of time since switching from the green screen to the cinetronic). I only have 90 wh batteries. I was wondering if anyone had any experience with flying a shark fin on the bottom stage and doubling up batteries rather than flying a bigger battery?

     

    It may be a terrible idea though. But an idea nonetheless.

  10. The thing that would scare me is if brushless gimbal technology keeps moving forward at the rate it is currently going and the wheels loosing their compatibility with the newest and best ones. (granted, given the way they communicate I don't forsee that being an issue, but still)

     

    That all being said, the ability to use wheels to control one of the brushless gimbals makes it orders better in terms of usability.

  11.  

    A quick look at that Arri price List seems to indicate the opposite?

     

    iB

    Agreed. I like the Arri stuff, but it looks to be fairly more expensive.

     

    What about the wait times? I know Preston has quite the backorder log right now.
