Now that's what I would call a Rube Goldberg quad! Complexity for the sake of making it complex, with moving rudders, the metal framework, four batteries, and all the other stuff on there that thing must be HEAVY but probably steady in a wind. I know from my heli experience that I'd rather be...

Motor to motor is about 600mm, its bigger than my standard MK Hexa and very close to the same size as the AD-6. I made the arms from the 1/2 inch square stock I have so its easy enough to make adjustments in the length, started with 30 cm mainly because it was half the length of the pieces I...

I think I may need bigger motors before this is over with, the frame is a bit bigger (and heavier) than I anticipated, certainly a fair bit more than the flimsy MK quad frame... It is a solid piece though, there won't be any question that the frame is strong enough and it won't...

Just about to start the build of a Y6, a first for me. I've flown a lot of different configurations but never a Y6, so when it became obvious that the Hoverfly board wasn't happy in its MK quad frame home I decided to take the opportunity to not only give it new frame but also to try out a setup...

I used a couple of 4 inch tie wraps and put it all the way around the standoffs for the stack capturing the ribbon cables right about in the middle when I bothered to do it at all. Had that on there for a while then had to take the stack apart for something and never bothered to put it back. In...

I had mine setup as an X8 so it wouldn't really be same anyway. Bart, you did do the proper calibration of the ESCs, yes? By that I mean attach all of them to the I2C converter and install a bind plug on it to do the calibration. If they were done any other way it might be contributing to the...

There's a couple ways to do it, you can solder header pins to the BLs in place of the C & D connections and use servo cable with the appropriate connectors on both ends or do like I did and solder some small gauge noodle wire to the C/D connections on the BL and then crimp a servo connector on...

I have seen both a Hexa and an Octo fly minus one motor though neither one was an MK, if I can find the links and the videos are still on the web I'll post them. Doesn't mean any or all hexa will fly that way, I imagine the RTF weight and a lot of other factors come into play there. There have...

The I2C isolator board keeps a short downstream of itself from locking up the entire I2C bus as it will if all devices share the same path to the flight controller like they do attached to the PDB. By putting the board in line between the F/C and all of the BLs, a failure of any one BL will not...

The German word for tilt is neigung, I suspect that nick is either a slang term or a dialect version of that to refer to tilt as I had never heard of "nick" being used in place of tilt before I entered the world of Mk and all of its wonderful Teutonic idioms. Ken

Depends on the version of firmware but anything even moderately recent should not allow motor start without doing a gyro calibration first. Ken

Some more added to cookie jar... Ken

The short answer is no, it will fly perfectly fine without but you won't have a lot of features that would get by having them. The basic flight controller gives you altitude hold and autoleveling, if thats all you need for the flying you'll be doing then the other boards can be left out...

I've had my share, some were pretty spectacular. I got at least two of them recorded from the point of view of the FPV camera on the quad not to mention getting to see it live from that point of view, not recommended if you easily get motion sickness! Here's my little scratch built 350mm quad...

Or you could just get one of the Flight control crash cage now being offered, see it here... http://www.droidworx.com.au/conceptx.html Ken

At a couple minutes past 2:00 eastern time the Hoverfly GPS went up on their website for preorder with delivery in late August/early September. No, I didn't order one, I'm not going to pay $450 to be a beta tester of an unproven product with limited capabilities when they're still trying to get...

I found myself needing to order a few odds and ends for the MK fleet so while I was online doing that I added a copy of Aerosim for those rainy weekend days when you want to be out flying but just can't. Now I already have a perfectly good copy of Realflight that I used extensively back in my...

If the servos you are using on the camera mount are capable of drawing more than 1 amp each, which is pretty much any servo used for mounts bigger than the Hisight II, then you should NOT be using the circuitry on the flight controller to drive them. The recom used on the power circuit for the...

Apparently they did do extensive testing with the multis they have on hand and they didn't observe this behavior, probably because there's a number of things that have to be present for it to happen and they may have only encountered some of the conditions needed but not all. Having done...

I got to the root of the problem last night, partly an issue with the MK frame the Hoverfly board is sitting on, partly an issue with the code. Here's what's happening, after the board is powered up but before its armed the camera mount will respond to tilt commands from the TX as well as...
