But ultimately it boils down to what you are use to and like using. There are no rules for open source tool choices.

I have not been able to install avr studio under wine on my linux box yet. It insisted on picking up some extras from MS and failed. I hate to switch into windows to use avr studio. I am running debian unstable AMD64.

BTW, avr studio 4 pointed to a dummy, I could only download 5 or 6 after register.

But does anyone have a definitive setup that works great for this? I am running DT 750's with unflashed rctimer 30A esc's and 10x4.5 gem fan props. My quad is set up off of a radicalrc.com stinger frame. Thanks for any opinions.

Original firmware

Will no one share their tx settings? Aero or heli?

Love this board. Bought 4 already and have one more on order. But quality control sucks. Wonder if HK is using child labor to put these things together...

And this is all I have to say about this:

KK2 board Quality Control Issues (2 min 28 sec)

It's there. It's the actual white layer that is stuck to the board with double sided tape that is coming off the underside of the LCD unit.

Best,

Yeah, my first KK2 came like that too, and I'm not expecting the double sided tape to all of a sudden work when my second unit arrives. I don't think it's the poor kid's fault, lol, it's probably just the poor quality tape they use. I just added a drop of Welder (like Goop) to hold the first one down; plan on doing my second one like that as soon as it arrives. Only special (expensive) double sided tape will last longer than a day with the kind of heat we get in my area anyways.

I don't think it's the poor kid's fault, lol

OK, maybe I'm a bit harsh with the poor lad.

I saw the mention of 50 over on the KK2 Tricopter Twitching thread

"Just flashed mine this morning, and got her all set-up.

No more wobble!

Set the servo filter to 50 as suggested by kk, and not a hint of wobble.

I really like how stable this board is on takeoff. No drifting or yawing from propwash on takeoff.

Opinions please. I have been able to flash control boards quite easily using the multicopter flashtool, (latest 0.63) a USBASP programmer and Lazy Zero firmware. I recently tried to upgrade my KK2 board with the latest firmware and although it said the flash was fine, it doesn't work, just constantly scrolls when I put it in my Tri. I also find that I cannot now flash any of my HK V3 boards. By process of elimination, I know that it's the flashing that's at fault. My only conclusion is that my USB programmer must be malfunctioning somehow. Has anyone else had the same problem ? Do the USB programmers go duff ? Your comments please guys would be appreciated.......

Programmers can go bad, yes. Sounds like you're having difficulties with yours for many applications so you might be right in your deductive reasoning. If you've used your programmer in the past and it won't work anymore with multiple applications, it likely went "duff."

Best,
Chris

I noticed that now, with glasses on . The solder job on pins etc. is not very impressive either.

Yes I noticed a few problems on my new KK2, I had posted my findings several pages back, the QC is definitely lacking. I haven't tried mine yet, still waiting for some missing screws on my DJI F450 frame.

Hope you get it sorted out Chris...

Hi, it looks like the backlight coming away from the LCD.
Whoever puts the boards together for HK would get those LCD's in as one piece. They should, however reject dodgy ones.

Glue should do the trick.

The backlight is actually just a very thin strip along the bottom edge with a central SMD LED, the white is just some plastic backing film to help reflect light through the LCD.
