    Mikrokopter: Basic GPS, Altitude Hold, use

    Yes, it maintains the orientation it had at he start of the route unless you yaw it to another, then it will maintain that orientation. Typically what I do is get it to the altitude I want and set altitude hold, then start the route while watching live video feed from the GoPro camera, I can...

    Props, props, and more props

    This afternoon I got a chance to try out the Hoverfly quad with the 11 x 4.7 APC props on it and as expected they do generate a lot more lift, I was hovering a little below 1/2 throttle instead of the just slightly above when fully loaded on the 10 x 5 Graupners. It flew fine, the extra inch of...

    Video from Hoverfly quad

    Very easy, maybe 8 little screws to take out then the boards can be removed. With the boards out you can get a grip on the old lens with pliers and unscrew it using a wrap of duct tape to protect the lens body. They use locktite or something similar at the factory, so when removing the old lens...

    Mikrokopter: Basic GPS, Altitude Hold, use

    No, position hold will work fine without altitude hold No, it's not required but highly recommended to use altitude hold while the GPS is navigating due to the tendency of the to MK drop in altitude as it moves from point to point. The behavior in straight position hold depends on the...

    Cutting props down in diameter

    There isn't enough difference in the blade root between a 10 inch and 11 inch APC prop to make it worth the effort of cutting the 11 down. Within the same brand and type of prop there's also not that much of a difference in the blade itself from 10 to 11, the only time I would even consider the...

    Cutting props down in diameter

    The APC props arrived today, since the Hexa is down until the new F/C board arrives I put 4 on the Hoverfly quad to test them out. First thing I noticed, the blades are much bigger and shaped very differently than the Graupner props. Next thing I noticed, the tracking on these things is crap...

    Muti rotor on film crew

    Hi Dave, welcome aboard! You may want to start with the counseling because getting pro quality video from a multi can drive you crazy at times ;) I'm sure you've heard the way to go is to buy a Mikrokopter and for the most part that's true to a certain degree, and it's also the most...

    Video from Hoverfly quad

    Here's the most recent test flight of the Hovefly quad, I'm starting to get results close to what I can get from the Droidworx Hexa which is somewhat surprising considering the part that went into building the Hoverfly. This is the current setup, a MK Hexa frame reconfigured to be a quad, 4...

    OH NO! Where did that smoke come from????

    I've already taken the servo recom off the board but haven't tested it. Yes, it is possible and actually fairly easy to test a component like a recom out of circuit and later I may take the other one out and see if there's still a short to ground. If the short goes away then it's likely the 5...
