The Fedex man just dropped off a couple DJI goodies, some early Christmas presents for me... ;) The datalink will be going on the CineStar 6, the Naza goes with the Flamewheel kit. I have another Naza on the way that will replace the WKM on my quad and that WKM will be replacing the MK...

I'm using the AXI 2814-22 motors, not sure if AXI has a recommended prop size but equivalent motors from other manufacturers range from 11 inch up to 13. So far I've found the 11 x 5 to be the best and the APC 12 x 6 a close second, more testing will be done with the APC as soon as the windy wet...

I'd have to say both. The DJI is very sensitive to prop size on large multirotors, much more than on smaller ones which don't seem to be as fussy about it. The thing that causes the biggest problem with the WKM on any large frame is too much prop, unlike with MK where you can use a 13 or 14 inch...

I didn’t touch the code, used the compiled hex file as it sits on the download site. When I have a spare minute or two I’ll download the other files and see what can be changed, not that I would since it seems to work fine as-is. It should but as it’s a clone there are no guarantees that it...

For a while now I've been thinking of trying SimonK's ESC firmware update on a set of ESCs used with a WKM controller. One of the things that's been stopping me is the fact that it's a one way conversion, there are no copies of the factory firmware available so once you reflash, that's it, you...

You could try here as well, the less expensive ones are out of stock at the moment... http://www.nghobbies.com/cart/index.php?main_page=index&cPath=59_119_157&sort=20a&page=3 or you could talk to these folks, they'll make you exactly what you want and ship from NB if you're in Canada...

Hi Tabb, Based on having used the exact same AV 130 with both Mk and DJI, I'd have to say the DJI has the better gimbal stabilization. Granted the CS6 is a bit bigger than my Droidworx AD6 with MK electronics but the AV130 does a much better job of keeping a level horizon under the CS than it...

I have a Dex frame sitting on the shelf waiting for me to find the time to do something with it. It is a bit of an oddity and they are very hard to track down as they're handmade by a person somewhere in central Europe. When I had the chance to acquire one I did simply because I found the...

Last I knew the gimbal Automatic Gain Control settings defaulted to 2, the servos will not move at that setting. The gain settings need to be at least 10 to get motion from the servos, the actual setting you want will depend on the gimbal and type of servos used. I found that it generally it...

If you're in ATTI or GPS mode, then yes it's normal. Only in manual mode do the motors not start up as soon as it's armed. Ken

If you plan to use the power module, hook it up on the bench first and make sure it's working correctly, many people have had issues with it. Make sure to measure the voltable on the connection to X1, some people have found it to be much higher than 5 volts resulting in some ruined equipment...

Yes, 12 inch is way too big for a 550mm quad unless it's extraordinarily heavy in which case it should probably be on a bigger frame anyway. For that size frame and depending on the motor kv and battery in use, I'd be using 10 x 5, or again if it had a bit of extra weight to haul around an 11...

In that case I'd swap the RX and possibly go as far as trying a different TX as well. Ken

Which is what they said on first release of the WKM about the "introductory" price that I and many others paid only to see the price drop even further several weeks later. Sorry to say I cannot believe any promises being made by DJI when it comes to retail pricing. Ken

Swap out the control module and see if it works then, if so that module is bad, if it doesn't then it has to be one of the non-DJI components. Ken

MK uses an addressable bus where all the BL controllers are listening to the same data stream for commands from the flight controller specifically for themselves. If something happens that shorts one of the lines carrying the data then all BLs lose communication with the flight controller...

I get them direct from APC, order from their website. Will only get to 55 or so here today with the clouds and rain, was over 60 yesterday. Locally we hit 70 over the weekend although it was a bit chilly early Saturday morning while I was at the sheep pasture doing a video. Too bad you don't...

Yesterday I received the APC 12 x 6 thin electric props I ordered for the CineStar 6. Had a short window to install and give them a quick test before dark but managed to get a short test flight with the 5N on the platform recording. From what I see in the short test these props are doing to work...

I think the batteries on top makes for a more balanced setup when heavy payloads are carried, having the weight up top counters the extra weight of a large camera hanging below the frame keeping the C/G closer to the center of the frame rather than well below it. The larger engines will not be...

Very nice! I'd like to have something like that to work with myself, been giving it a lot of thought and what you have seems to make the most sense on how to do it. Regardless of the flight controller you use I think it's probably going to take custom code to make it work, servos vs ESC is just...
