I too find that v1.03 works better than v1.6, in terms of the yaw coupling EMI problem. What we do now is mount the HFG board about 6" away from the camera body, and that, along with using v1.03, seems to work with the cameras I have on hand, which is a PJ710V, a NEX-5N with a 24mm lens and a Sony RX100. Surprisingly, the NEX-5N has less on an issue with this than the RX100. As expected, however, the PJ710V is the worst. The HFG board can be within 4" and the NEX-5N will not cause a problem. The RX100 needs to be at least 5" away and the PJ710V a full 6".

I also agree that for a "pro-type" system, with big boy pricing, it ought to work better in the environment it was designed for, and it should come with a much more complete owner's manual. Like everyone else here, we've had to figure out by trial and effort just what the settings do, and how to use them.

But here is the bottom line. It's a CAMERA GIMBAL FOR MULTIROTORS!!! We all have tons of servos, wires, carbon fiber, cameras, video transmitters, motors, BECs, stainless hardware, batteries, and high amp power distribution boards all in close quarters. If the HFGIMBAL is disturbed by .5V, then I think we have a major problem with the design of a product that cant cope with the environment in which it needs to function in the real world. I'm sorry, but I have 21V @ 450A running through a mass of wires within just 6in of the stabilizer. I fly big cameras/glass and packing stuff close together is an unavoidable reality.

I have a CNC router and can make my own components. I can router another mount that places the HFGIMBAL 15 feet from the camera. But that's not the point. The point is that this stuff supposedly for professional use. That means it needs to work out of the box every time. What are we doing spending hours playing with settings, RF issues, bugs, etc? That sounds like hobby grade to me. I'm not a hobbyist. I find no joy in tinkering endlessly.

I'm not saying that product design and manufacturing is easy. Major props to HF for making stuff. And I can always look at it and say hey, what more do you want for $350? Thats dirt cheap for as much work as goes into prototyping and coding it. At the same time I would pay x10-x20-x30 more for something that is for professionals if it actually worked...and came in a case that shielded it from the environment, and when traveling, and from fear static electricity, and had positive locking connectors...right?

Hoverfly - is this a stabilizer for someone like me? Or am I asking for something unreasonable out of the product? Shouldn't products solve problems and make work easier? I'm feeling like my needs aren't being met.
Im getting yaw problems as well, They start randomly. If we land and re boot the gimbal it fixes it some times. very annoying.
Can we please have a fix Hoverfly?

Using 1.06, happy with everything except for the yaw coupling problems and the fact that sometimes the horizon will stay level and perfect and other times it gets stuck crooked and almost like it forgets where level is...

If someone was running the camera, were you flying in "Course Lock" or "Carefree" mode? -- that is the most questions I have ever asked. -- JOHN
Yes sir. Yea, in the boat the whole time. Brought generator on board and charged in there as well. Landed and took off from back of boat. Have a friend who runs the camera. I was flying in atti mode. Thanks for the kind words

Sorry, I posted that, then after watching your video a second time, I saw the credits at the end, and saw my answers. Was changing my post while you were already responding. Do you have one monitor that you both watch or does just the cameraman watch the monitor and you just fly LOS? -- JOHN

You do amazing work and I am sure that most of us (especially myself) would love to have even 10% of your piloting skills. Not to take anything away from your amazing capabilities but... wouldn't it have been nice if the gimbal controller could have lived up to your end of the deal and maintained a level horizon? The fact that there is such great action combined with your obvious display of piloting skills one does not fixate on the issues with the horizon. Had this been anything else I think that it would be more noticeable.

For anyone using CS6 Premiere Pro and Photoshop I have finally learned (out of sheer desperation) how to correct the horizon in post: You can edit the crooked clip in Photoshop via the 'lens correction' filter.

Here is what I do: From Premiere choose to "reveal clip in Bridge". Then from Bridge choose to "Open with Photoshop". From PS Filter drop down choose to "Convert for smart filters". Then from PS Filters (again) choose "lens correction". Once there click the tab for "Custom". There is that little 360 degree (round) controller called "angle" at the bottom of the lens distortion window under this Custom tab. You just rotate this until your horizon is corrected, then render the video and save it. It works great. It is a pain in the a** to have to do this and not one we signed on for but if you have the talents that this guy has your video may deserve this final touch. You can also use this method to apply ANY of photoshop's corrections or effects to your clip! Imagine the possibilities.

Again, GREAT WORK!

May I ask for help here !
I cannot move my gimbal 90 degrees down ( to be vertical down ).
In angle position it goes around 80 degrees but not exactly and in angle velocity only 45 degrees.
What should I do to achieve 90 degrees down with angle velocity ?
my mount is av 130

Have a monitor mount setup above the cam op's dx8, I sometimes use it to help with depth perception but we are gonna get him a set of goggles and mount the monitor to my 8fg so i can have it as a reference.

Thank you very much.Flying 3d helis for a few years and flying planes before that has helped to make flying the cinestar very easy and relaxing haha

Did you try adjusting the endpoints in your radio?

Did you go into the receiver config menu and click on Current Angle Set Range button on the pitch channel? From there you can adjust the Max Deflection, which should control how far it tilts. Depending on your gear ratios, servos, etc, you might have to put in a number higher or lower then 90 to actually get 90 degrees. Mine tilts from level to 90 degrees with a setting of 87, go figure.

I use Angle Position as well.
