Does anyone have a recommendation for a 3-axis gimbal for an Iris+?
The only option I have found out there is the DYS 3 Axis. Are there any others that work with a GoPro Hero 4 Black?
Thanks, erik
p.s.
If someone who owns a DYS and an Iris sees this, I have a few questions:
- Does the DYS integrate with pixhawk?
- Meaning in auto missions or follow me, will the Iris+ be able to tilt the camera up and down to keep the subject in frame?
- Is there an interface plate, or do I have to find someone to 3D print one for me?
- Does the DYS work with a GoPro 4 black?
- How are the vibration levels?
- Is it difficult to install
- Complicated software config I can handle, but on the hardware side I'm pretty awful at soldering and tend to really mess things up.

I have and Iris and an x8. I use the DYS 3 axis gimble on both, total plug and play with no tweeking. I use the factory mounting plates on both ships and bought no aftermarket brackets. Had to install a stepdown bec on the x8 because its runng 4s. Too many volts for the gimble. Or you can install a little 3 cell lipo to independently run the gimble. Great gimble for the money!!!
Before I bought another DYS, I would like to see actual footage from the Gimbal...
At first I was all excited about the solo, but from reading some of the problems think I will wait. I was kind of swaying away from the dji stuff due to poor quality and bad service, but now messing with pixhawk and open source hardware, im leaning back to dji. Still messing with PIDs in the iris and x8 to make them hold in loiter. Just bought the inspire which was ready to fly out of the box, My x8 and iris flew like crap until I did a compass calibration. for a while hated phantoms, but now the p3 brought back my confidence. Friends have been flying the snot out of them and when I flew a inspire for a few hrs, loved so much I bought one. My local dji dealer told me that DJI has hire double the employees and moved to a bigger facility to stay ahead of the game.
Buy an inspire!!!!!Love mine!
I would really like to see some video results from the XProHeli SteadyGo 3-axis gimbal (I've searched YouTube and have found none).
I've watched a lot of videos from guys on the RCGroups forum using the Feiyu Tech G4, DYS, and Align G2 3-Axis gimbals. All of them seem to suffer from some level of horizon drift when turning during forward flight motion. I think a lot of it has to do with a lack of a communication channel between the flight controller and the gimbal controller.
As I have mentioned above in this thread, I own both the DYS 3-Axis and the DJI H3-3D gimbals. My biggest complaint with my DYS gimbal is that it suffers from YAW drift during forward motion of the multi-rotor (where as the horizon is solid). My H3-3D on the other hand is rock solid in all three axis during various flight maneuvers. Perhaps the H3-3D is more solid due to the CAN bus comm connection between the Naza V2 F/C and the H3-3D GCU, I don't know.
I am thinking I might be able to improve my DYS performance with my Pixhawk controller if I were to use the AUX channel outputs between the F/C and the gimbal controller. Right now, my DYS gimbal controller is free standing, and pitch is controlled by a spare channel on my S-bus Rx. I've spent hours trying to tune my DYS, and others on RCGroups have just given up on the DYS.
It will be REAL interesting to see the video results of the SOLO with its 3-axis gimbal! Though I don't usually like the "boxed" solutions like the Phantom, Inspire, or Bebop (or Iris for that matter), the SOLO looks really cool, and pre-sale videos seem to look pretty awesome. And I really like the programmability of the 3DR flight controller (it's the one reason I haven't pulled it off my big hex with the DYS gimbal). I'm ready for my next aerial video platform...
Align G2 Horizon Drift (starts around 1:10 and 1:20):

It's possible that when using the front mounted GoPro on the Iris that the balance (CG) was off, contributing to flight instability. I find that both my Hex (using Pixhawk) and my quad (using Naza V2) fly much better when I use the battery to counter-balance the weight of the gimbal and camera (I just mount the battery further back with Velcro and a Velcro strap). It will be interesting to see how the Solo performs with a fix-mounted battery (and no way to compensate for the forward weight of the gimbal / camera).
My buddy has a Phantom 3, and I must say the video (link to ground station) is pretty awesome at 720 res. and DJI's camera shoots some really nice footage at 4K / 30FPS (or 24, I don't recall exactly). And there's no fisheye either (but that can be handled on GoPro by going to the "Narrow" field of view option).
My only comment on 4K at 30FPS is that it (GoPro) doesn't respond well when the camera rotates quickly, the video gets a little choppy at 30FPS. At least at 2.7K, you can record at 60FPS, which is best for an original source video, then edit as needed. Not sure if the P3 camera has that option. As far as bit-rate, just be sure to get a SD card that can handle the dataflow - Sandisk has several mid-priced cards that perform very well.
Yep, I run the same SD Card in my GoPro Hero 4 Black. Seems to do just fine.
Raw video off of the P3 looks really good in my opinion, even at 4K.
As said just about everywhere else, prop balance and proper dampers seem to be the key. My DYS has way too soft dampers, and I think that contributes to some of the unwanted movements in my videos. Tried using the DJI white damper balls in the DYS holes, too big. Have to see if Tarot dampers will fit.
The black tarot dampners will fit. I use them on both my dys gimbles on Iris and x8. Still dealing with some vibrations. I think the standoffs are hitting the thru holes on the upper plate, so im going to dremil out the holes bigger so they do not contact the standoffs.
