    A 360 degree GoPro brushless gimbal

    Purchase Here

    For the past 6-8 months I have been brainstorming optimal configurations for the gimbal system of individual camera types. Here is my optimized brushless gimbal with a purpose driven design - specifically for Hero3 and SJ4000 cameras.

    The mounting bracket pictured is the first available. It attaches directly to 400Q and 400Q-X frames. For the GoPro to be in the best position, just flip around the clean plate. Now the area where the Hero3 used to sit is sticking out the back. Pull out the battery a bit to adjust the CG to perfection. Or, use a bigger/longer battery.

    The gimbal supports a wide range of motors while maintaining balance. I put a lot of effort into making sure the motors are always under the smallest load possible - this saves energy and produces less heat. The first major step I took was to switch the roll/pitch positions around. If you can figure out why I did this, great! If you can't, you'll just have to trust me that I worked the numbers. Maybe a little too much time was spent on this particular design, but I want it to be just right.

    Personally, I want to be able to fly just as crazy as I usually do with the gimbal attached. This gimbal supports motors with a hollow center if you prefer slip rings for 360 degree rotation. Movement is not physically limited to a set range of motion.

    This allows you to keep using your FPV quad airframe just as you were before, whether the gimbal is on or off. For extremely aggressive flying, you will need to make sure your wires are secured properly.

    I've accurately and precisely modeled everything down to the exact FOV of the GoPro, checking to make sure props are never in view. So here it is. CCD mount optional add-on.

    So how does the camera stay attached? The simplest and easiest way is to use a strong rubber band. There is a place on the top of the bracket to hook the rubber band around, and another on the bottom.



    GoPro Hero3
    Use 2208 motors or equivalent weight motor for perfect balance(10mm slip rings).

    SJ4000
    Use 2208 motors or equivalent.

    I forgot to mention the gimbal is 154 grams with the Hero3 attached. This is about 100g less than non optimized gimbals.
