Ken I'll have to ask you to give a little more details on your last response please. I'm going to be building WKM bird for APV, what situations would you prefer the flat to the Y?
Also debating whether to just build a Quad with larger motors and props. Thanks
My experience has been that the flat hex is a bit more stable than the Y6 overall so if raw video quality is the main objective I'd have to say that would be my preference. In cases where redundancy is a big concern, like when having an expensive camera sitting on the platform, I'd lean more towards the Y6 and fly it a little differently to smooth it out as much as possible. I'd probably also use the Y6 more for stills than the flat hex for a couple reasons, one being the last little bit of wobble that is proving hard to get rid of in the Y configuration wouldn't be as much of a concern, and not having the motor out front would be another in either case. There have been days when the angle of the flat hex in relation to the sun has caused what I can only describe as a subtle horizontal scan line effect in the video as the spinning prop briefly dims the bright light as it passes through its travel over and in front of the camera lens. Having the widely spread front arms of the Y6 minimizes the effect though in some circumstances it can still occcur but it's much less of an issue.
The Y6 seems to have better yaw authority so if its a case of flying in close quarters that requires a lot of turning in place I might favor the Y6 for that use as well. Either one is pretty good at rotating on axis without much drift but do feel the Y6 has a slight advantage, then there's the matter of less arms to potentially come in contact with something but if the flying is that close I'd want to have the smaller quad and GoPro anyway.
I just did a back to back video flight using the MK/Droidworx AD6 and the WKM Y6 within about 10 minutes or so of each other. Flew the same route using the same exact GoPro camera and with similar AV130 mounts under each. I say similar because the older one under the AD6 has Hyperion servos and the newer one under the WKM has Savox and is noticeably faster and less prone to twitching. I still have some adjustments to make on both multis and on the older AV130 servos now that I have the programmer for them but the end result is they've close to each other in the raw video that came out of the camera. I'm going to edit them down to a couple minutes and I'll put them up on Youtube later for comparison.
Hi Ken
On setting what changed between the two ships as far which gains and advanced setting did you change wondering how close the flat hexa and Y-6 really are.

The changes are small and I'm still working on it. I did just find during the video flight that I need to turn the Altitude gain down on the Y6. At one point I just pushed the throttle to full max climb and it responded with the first true gain related oscillation I've seen with the WKM so I need to reduce the settings and try again but that won't happen today as it's just about to get dark here and I'm out of charged batteries. I have to say I've never done a full power climb attempt with the WKM before so I had no idea what to expect, now I know. Did the same thing with the MK/AD6 and it took off vertically like it had JATO pods on it, clearly the six big Pulso motors have no problem lifting its 3 1/2 kilo RTF weight!
