WKM and MK head to head part 2

[RTRyder]

This time with the little multis, representing Mikrokopter a box stock MK Hexa V1 with nav and a Hisight II camera mount (my original MK) and the WKM on an MK quad frame with Coptersky landing gear and 2 axis GoPro mount. Flights within a couple minutes of each other to about 300 feet using GPS position hold and vario altitude control. Altitude verified by the flight log on the MK which maxxed out at 90.4 meters or just under 300 feet, WKM went a bit higher probably to around 320. MK RTF weight 1950 grams, WKM RTF weight 2240 grams, both using 2 - 2s 5000 packs in series, both carrying the same GoPro. On these flights it's easy to see the WKM was much less of a handful, I had to keep correcting the Mk at the start of he climb to get it to stay where I wanted it to be. Once it settled down it stayed put, but the WKM just went where I wanted without any need to bring it back from drifting. Video is raw unedited from both flights with landing gear and motors clearly visible to judge movements...

First the WKM...

And now the MK...

Must say you have them both well dialled in there and the mounts are performing great on both machines , but yes I could see the WKM looked the less handful machine .

Excellent. Do you have any pics of the mounts? Did you do anything to them, other than replacing the servos? Which servos are you using?

Ken again great testing there.. thanks for takinig the time and effort to help everyone out on their FC choice. I just got my 450 WMK frame and will post pics later. Like the WMK FC it looks TOP quality, from the packaging right down to the set screws that hold it all together.. It would be good if we could get a frame to you for your thoughts..

How about it Geoff.. any chance you cold get DJI to send him one for testing?

Here's the WKM setup...

This is the only picture I can find of the MK with Hisight II at the moment, I have plenty of pics with other mounts under it but hardly any with the Hisight...

The Copterworks GoPro mount was a disaster as delivered, I had to take it apart, fix all of the problems it had, and then reassemble with the Savox servos and spend a week or so getting it dialed in and I'm still not 100% satisfied with it. At least its useable now where it was little more than a paperweight when I got it. Servos are Savox SH-1250MG, the only ones that fit the existing mountings and have the speed and resolution necessary to make it work, I tried others before settling on these. Somewhere here in the forum I have a thread that goes into great detail on what it took to make the little bugger work, can't remember which thread at the moment.

The Hisight II mount is about as basic as a camera mount can be, only thing I've done to is replace the analog servos with HiTec 5065MG servos programmed specifcally for each axis (travel, centering, deadband, etc.) and again spending a lot of time getting it dialed in. I am amazed at times at the performance that the Hisight is capable of, unfortunately its capacity is limited but it's what can you expect from a sub $200 mount. While I can fit the Sony Nex 5N on it, it struggles to move smoothly with that much weight so I limit the load to a GoPro and it works fine.

So other than the servos the biggest part of it is setup, setup, testing, more setup, and more testing. If you take the time to make sure the mount works the best it possibly can, mount it to the airframe properly, and most importantly make sure the flight controller parameters are matched to the mount and it's limits then you should get similar results. That's really all I do with my gear, there is no secret sauce that makes it all work like magic other than what I just described.

I did finally get my mkTR Pro mount dialed in pretty well, but because of my "staying-in-the-air" problem, I didn't get too much time to test the mount performance. What I learned, however, is this is just too much weight for this X8 setup, because my poor little Hyperions are having to work too hard. I'm going to remove the mkTR Pro, and save it for a larger Y6/hexa (still haven't decided...). In its place, I'm installing one of my old AskmanAP TRex landing gear sets and then I'm doing a new GoPro-specific mount, based on using the new ServoCity servo blocks. Yesterday I ordered some of these, along with two ultrafast Hitec HS-7940TH titanium digitals. I'm going to mount the GoPro using a simple L-shaped aluminum bracket. The other end will use a short piece of 5/8" aluminum tubing that will be fastened to the dampened cross member on the landing gear. Hard to explain, but I'll post some pictures in a new thread this weekend. The blocks and the servos will be here tomorrow.

That I remember from when I had my mkTR V1, the weight, my stock MK hexa V1 was pretty much maxxed out flying with it. My solution to that problem was a Droidworx AD6 heavy lifter with AV130...

My WKM Y6 is being decomissioned this weekend, the controller and AV130 will be moving to a new home soon so watch for a new build thread starting sometime next week.
