    You got me going there for a minute:)
    Well here's mine with a much bigger camera still working on the pan axis.

    Cheers

    It looks like these motors will have enough torque to handle the 5d with a smaller lens? Obviously not the EPIC but just the 5d would be awesome.

    Yup they work great with the 5D as long as you get your balance sorted. Really sorted!

    Probably some money to made on custom winding of motors with all these DIY's and Movi etc. We are going to see a ton of motors burning out due to balancing issues.

    Brad is right. If the camera being Epic, Canon C300, Sony F55 or even the NEX they have to be balanced perfectly.
    There's no torque to those motors and I think even a gust of wind might upset them.
    Those are the 5206 I have the 5030's which I will try on another CS gimbal. I just don't feel like taking it apart since is working.

    What is the torque rating on them? I wonder what kind of torque the motors from FF have?

    Isn't the real issue the amount of amps the controller can do? You can always wind a motor to handle more power. I thought that was the whole reason for rewinding the motor, so it doesn't overdrive the controller?

    The Alexmos controller outputs 2.8 amps per channel if you use 15ohms motor

    More or less yes. Build it and they will come:D

    Too much torque and we might see some damage to lenses or cameras if there are malfunctions with the boards. I know I have had my Radians lose their minds on a few occasions and I had a few moments with Alexmos and Martinez boards the last few months. I can only imagine what unlimited power would have done.

    Ha I knew I couldn't be the only one, I converted mine as well. I 3d printed the parts I needed, and used the 5010 motors from rctimer and the alexmos controller. I still have some high frequency vibrations in the airframe that are making it through the damping, but the gimbal is working really well, as long as the camera is well balanced. I don't have any pictures of the gimbal itself, but can take some if people are curious. A short clip from test flight is here:

    Hi Steve: What 3D printer did you use? I was curious as to which one might produce strong enough parts?

    Andy.

    Hi Andy. I'm using an Ultimaker, printing PLA. The roll motor mount isn't structural at all, so I'm not really concerned about that; worst case it fails and I loose a shot. The pitch motor mount however is structural, and if it were to fail I'd loose the camera. I've built and destroyed a few versions (intentionally) to understand the properties of the printed parts, designed accordingly, and am pretty sure that if anything happens that breaks this piece in service then I'm going to have much bigger problems on my hands; flight loads are no concern. What's *is* a concern is that the parts are built extruding plastic filament through a heated nozzle, and if I ramp the power up enough to handle the 5dmkIII + 24mm 1.4/L (currently the heaviest lens I've flown) the motors generate a fair amount of heat. I'm monitoring the pieces for distortion. So far, so good, but I could imagine it being a problem. As a prototyping tool, the printer is awesome.

    Hi Stive,

    It looks like another world.. Good job! Have you tried to fly in windy conditions?
    I would really like to see some pictures.

    Hi Bill, i have to say.. nice work!
    I figured out that you replaced the Pan Motor with something of different..
    tried the 5206 and it doesn't work as you want?
    What kind of motor is this in the video test?
