    Do not load firmware V4.22

    Early reports are the re-release of 4.22 works quite well. I haven't tried it yet as it's raining here but I will give it a try as soon as I figure out why one of the motors won't spin up on my WKM quad, I suspect one of the wires broke where they go into the motor casing. If it works ok on the...

    GoPro Lens

    I have both stock lens and Sunex lens on the pair I have. The Sunex lens works well but you need a very steady platform for the end result to look good. With the Sunex lens any rolling shutter (jello) or camera mount/multirotor instability or vibration will be clearly seen, much more so than...

    CineStar 6 WKM build

    The frame should be able to handle any motor that will fit on the motor mounts, just how large that would be I don't know, the biggest motors I've used on any frame is the 2814 series I used on my Droidworx, the CS, and the Y6 the CS replaces. I would think you could fit something like the AXI...

    DJI mounting best practices

    The software has provisions to allow the IMU and GPS to be mounted almost anywhere so theoretically it shouldn't matter as long as the correct orientation and distance from the Center of Gravity are entered in the setup. Personally I like to get the IMU as close to the center of the frame as...

    Show Your WooKong M Videos HERE

    Not as well as I'd like but much better than it was. Today was the first time I was able to get acceptable video with this combination through three full battery packs and was mainly to set a baseline for more tweaking and improvements that will be taking place over the next couple of weeks...

    Redundancy, What's your experience?

    The ability to maintain flight after loss of a motor depends on a lot of things, not just the configuration or number of motors. Weight and balance play a big part, is there enough thrust to keep it in the air with 1 less motor? Is it balanced enough that loss of any motor will not be a problem...

    That's the DJI Wookong-m on a CineStar 6, I've got it working well but still trying for the "right" setup. It can be tempermental at times depending on the wind, not as smooth or stable as MikroKopter electronics yet. A great effort for a just released flight controller but they've got a ways to...

    3 mins from 8000mah???

    The AXI motors on the CS seem to be more efficient than the Avroto I was using, then again they ought to be for the price difference! Using A/H shouldn't effect the flight time, only the altitude ceiling if you have it set to fixed mode rather than vario. I fly my MK in vario from the time it...

    Late this afternoon I was trying some different gain settings on the CineStar 6/WKM and decided to get one last flight in before it got dark. After the flight I looked at the video to see how well the GPS hold worked and how steady things were overall. I was quite surprised at what I had...

    MK sport flying

    Last weekend out at the field I wrapped up the day by flying out the final set of charged batteries for my little MK Hexa V1. It was a bit windy so I decided to give the GoPro HD a little roller coaster ride and just have fun with it. Original vid runs about 10 minutes, I cut it down to a more...

    Aluminium tube thickness.

    I used pretty much the same thing on my Y6 build and it worked out well, even when I had it reconfigured as a standard hex with 6 - 1 foot long pieces of it. It was a bit on the heavy side but it flew well in either configuration plus the thick walls resist bending fairly well too. I use the...

    Gaui GPS

    The reported price for the GU-INS is around $900 US, for that price it better work a LOT better than the Gaui electronics I've owned and used. From the limited reports of people that have managed to get their hands on pre-release units it works but not nearly as well as the Wookong-M. If that's...

    Altitude Hold Problem - Pressure sensor?

    Setting max altitude to zero turns the feature off, max altitude is then unlimited. If you set the value to anything other than zero it limits altitude to that number in meters. Ken

    DJI Naza

    Sometime around mid-December they should be available, no one has any yet but there have been offers for pre-order. Rumor has it the entire kit, frame, motors, esc's, and Naza controller will be released around the same time, cost of slightly under $500 for everything. Ken
