    Did you hear the latest news from Freefly (as of last week or so?), via Instagram Live? With the upcoming Firmware version 2, they found a way to get roll to work with Movi Controller, and if you mount the Movi 90-degrees forward, so that the Pan motor would control the Roll axis, you can do infinite Rolls while the other two motors control pan and tilt.

    It seems this was a huge software challenge, harder than it appears. I think you need the Movi Controller in order to take advantage of it.

    Unfortunately, I can't link to the video as it's disappeared from Instagram now.

    no, i didn't see this... sounds cool but for now it would be cool enough to control the roll without endless function and with the ability to switch the control of the roll from "angle" to "rate". this would not be a big challenge.
    I have the roll on my rudder stick but it is in "angle" mode wich isn't very smooth to operate.

    i even do not understand why one need to have the MoVI Controller for an endless setup. it is just a remote and not the PID controller

    i find the RC remotes very useful to control the MoVI and also the range of the MoVI Controller is very limited.
    ah and it is expensive :)

    I have a feeling, but don't know for sure, that there is a bunch of elegant and fancy software coding that had to happen. Apparently, on the Movi Controller, you have to switch a few parameters to enable this mode. Gimbal Lock is one issue, and the other is the way the sensors seem to work on the Movi. Currently, if you flip the Movi 90-degrees forward, the Pan motor no longer functions in the same way. It becomes the Roll axis, and just maintains horizon, and doesn't respond to Pan inputs from the controllers.

    Again, I have no first hand knowledge, so I'm just guessing, and maybe someone from Freefly would like to comment more. Or not. Because obviously DJI is trying to work on these same challenges with Ronin 2 and is also apparently finding it more difficult than they thought.

    yes - gimbal lock is a problem if you want an endless roll and endless pan. they will eleminate each other in some positions.

    but this isn't what i want to have. it is only the way of controlling the roll axis. just go to the settings and you'll see that you can switch the tilt from "rate" to "angle". this is what i would like to have for roll.
    at the moment the roll is "angle only".
    also it would be great to have the majestic roll funnction with mimic.

    Hi Rolf,
    I'm with you, we don't need big change , just give us “roll rate” on one RC Controller channel.
    People should join us that FF team can hear.

    the problem i see is that one cannot use the trim switch of the RC for horizon trim anymore. the roll would begin to drift if this is used.
    but it is the same with tilt. just don't use the switch and everything is perfect :)
    in my DX7 i have a D/R switch configured to deactivate the rudder stick. after switching you can't control the Roll of the gimbal and the horizon is leveled.

    Just thought I would share the incredibly disappointing news with everyone I just learned... Movi 2.0 STILL does not include basic rate/speed control for the roll input for non-360 mode.

    With MōVI Software v2.0, you can roll with
    • MōVI Controller
    • MIMIC
    • Pilot
    • Gamepad
    • API

    Feedback
    • Software team doesn't necessarily monitor forum, facebook, etc.
    • If you want to ensure your message is delivered to team you can fill feedback from or directly contact Freefly support team
    • Software team haven't previously received requests in our system to add roll mapping to 3rd party controllers and this is not a feature that was added to v2.0

    Hi Deniz,

    You have always been able to roll, using the roll trim. Unfortunately it isn't useful because a) There is no smoothing b) The Trim is "angle" roll control. Users need speed/rate roll control for precise and smooth roll movements (especially when trying to correct for roll drift mid shot).

    The first thing I did two months ago when I got my Movi Pro was put in a support ticket because I was extremely frustrated there is no Speed/Rate roll control. Haven't heard anything from anyone since. I even saw this feature requested by users in forums over a year ago (whether anyone put in a support ticket or not, I cannot comment on).

    Every other gimbal you can think of has speed/rate roll control. It is a critical feature for drone work. Freefly makes the Alta, I don't understand how this feature could be missed.

    Anyways, hopefully Freefly addresses this issue sooner than later.

    Hi Chris,

    • Because like you stated, this is "roll trim", and not "roll"

    • There is so many other ways you can achieve roll shots currently. Added your request to add mapping option for 3rd party rc controllers as well. At every release we go over the list of hundreds of requests and prioritize them based on so many factors. Can't promise a timeline for your right now but hoping it will make it to the top priority list.
