Thanks Ketch.
As I mentioned earlier, the first pic's was my last setup in order to try and get the camera balanced...I have a Freefly carbon mounting kit for a V-mount battery on the side...this was my initial setup- and the one I went back to (like you noticed the tilt function did't work with the battery on the back so I went back to the battery on the side). I did like you said and added back the VIV MB...and just like you said, when I cut the Ronin on, it picks up the slack. Including everything one would need to run this gimbal, I'm weighing in at just under 14 lbs...here's my list:
Red Epic: aprox 5 lbs
Xenon lens: <3 lbs
Red Cage and wires: <1 lb
IDX Battery and v-mount kit: <3 lbs
Heden Lens motor and F:2 receiver: <2 lbs
Here are some pics.
Quick observations/questions.
1) The motors make some loud noises (humming) for a couple seconds...its off and on. I've skimmed the manual, but definitely need to go through it some more as I'm sure I'm missing something. I've downloaded the app, and attached some pics of how my Pan & Tilt reads are going...
2) It's heavy...all the stuff people are saying is true...it would be extremely tough for one guy to hold this all day for a +10 hr shoot...I'm either going to buy an Easyrig or rent one...or switch off to a second person to help when using this
3) I probably need the XL arms...especially given that I'm adding a MB to the front. The side battery mount feels good with the rig, but I'm sure it would be balanced more if I had room in the back to add a battery there.
4) Since we have the same setup, other than than the fact that my MB is rail mounted, I'm interested in knowing what your measurements are for the Epic on the Ronin..
Like I mentioned, with this Xenon lens, there's no way I can do a proper tilt balance. I am noticing that the motors are making a loud humming noise based on certain positions I have the camera in...this has to be user error...I'll go back to reading the manual and doing some research.
Here are some pics of what I have so far...no where near done yet as I've taken it off and shot around the house, but the gimbal has acted a little erratic a couple times...like flipping all the way upside down, which bangs my MB on the top row arm; and the overall footage doesn't look so smooth yet like others...I'm sure I'll get there, but for now, its hard...on the bright side, I don't need to workout my arms today! lol
Cool Rome,
As for your observations/questions:
1) The motors hum when their strength setting is inadequate to the payload, play around with the numbers on the motors of each axis till the humming goes away completely, there should be silent operation, so play with it, but be sure that once you did the best balancing permitted by your set up, you always run the Auto Tune and Calibration first, this should almost always do the trick for you, if not then do as I suggested.
2) Yes carrying over 20LB/25LB of gear in your open extended arms is not easy, you need to have some upper body strength, a work out 3 times per week for Arms and Shoulders would be ideal, and including some lower back routines would be also smart...
3) The XL arms Kit is one thing I suggested and strongly wished for one for a reason, now lets hope that DJI gets out sooner then later, but also do keep in mind that with the center of gravity further away form your body, the rig will fill much heavier on your arms, and your hands will also fill this the most, and so will your wrists, so an Easy-Rig like system will be a must to pick up most of the slack.
4) As I said Rome, the humming needs to go away with proper Tuning/Calibrating, done first in Auto mode, and then if need to by you on each individual Axis Motor, you need to play with the settings and your set up to see were you need to be.
Similar set up: Let me try to go a bit further on explaining this point as well as it really makes a HUGE difference balancing a camera set up form an other, even if we have similar set up, meaning we both use the Epic, the Xenon, and the VIV MB, is to see if you and I both use 2 4x4.65 Filters, + one 138mm Round filter, what accessories are we using, what type of Motor for FF, what type of Wirelesses receiver and controller for it, and what about Wireless transmitter for Monitoring, Battery weight and size, even when using both V-Lock batteries and so on.
Each of this items, even at the same weight and size, will change drastically the way balancing occurs and the way the weight gets distributed, deepening on were and how they are mounted on the camera.
Using a hand held stabilization system is surely easier then using a Steady Cam, and balancing is some what easier too, but still has a learning curve, which is easier or harder depending on Gimbal used, since I have used Hand Held stabilization system for years, and have palled around with as many as they came out, including now 6 different Brushless Gimbals, I can say with great confidence that while the Ronin is surely not the easiest and fastest one to set up, it is most absolutely one of the very fastest and easy to set up and operate, yet it is a unique Gimbal given the different modes it allows it's end user to operate with, and this makes that extra special.
