Just read Shane's Colton blog about acc mod.. What would you recommend? Is this version now work "safe" for you? Also what are these speed controllers that Shane uses? They seem custom...

Seems his new version works. I had Prob's with his first FW. But seeing i acro mine stick scaling at 90 for H/R's
i would be over the angle limit of 45 degrees? when flying my style...
So more then likely my bird will lock out the next time i pop the AL switch...so i could not be bothered...

KK's firmware1.2 is great as is...

I've started a little thing on my Blog...slowly adding stuff like my settings and talks about the board
Was going to do a run down.video of my set up tonight, but got bogged down with reading FPV material lol

QuadRotor - Situation
It was a critical situation at the end, i was so
involved and didn't noticed that battery ran out of
juice. It landed hard on the ground. No damage.
Also see fast forward, dust cloud and some close
call.

I made a lot of projects with AVR CPUs using ASM and C. My toolchain is WINAVR handled by AVRStudio4.

Meanwhile C isn't so bad compared to ASM as you say. The problem is that you can write software that is slow in speed and large in size.

There is a need to go deeper into the compiler properties. If you control the ASM-output of the compiler and look for unwanted LIBs, like float lib, or control the way of bit manipulation ... and so on, you will find a way to produce small and fast code.

Which problems do you have? The main problems with the SS ones, are timing problems (FET's shorting the battery) and problems with high refresh rates. None of these are related to the BEC.

Guys , this is my first quad build with a kk v2 ..here is the maiden video with most of the settings on default..kindly let me know if any further change is required in the gains judging by the hover.The only issue i have is with drift i have to be on the sticks all the time otherwise it tends to drift either lateraly or vertically.Its quite sensitive on every click of throttle stick on mid stick .



quad maiden (1 min 26 sec)


My setup

Bl 24 g 1500 kv x4
Prop 8x4.5
Lipo 11.1 mah 20 c
FCB KKv2.0
Esc Turnigy Multistar 20 amp x 4
AUW 525g

To deal with drift you are going to have to trim it out.
What type of radio are you using, u say "every click of throttle" does it have the ratchet style throttle?
have you made sure in your reciver test that all axis are set to zero? In tour sub trim menu?
If so and it is still drifting, open the sub trim menu and trim her out. I'm mobil and well watch your video later

Actully just watched the vid looks good. Looks like you have a small bit of high oscillation , so back your P gain down 5 and re test. Then start bringing up you I gain till you see slow oscillations then once there back it off till it smooths out. Once you have that you'll notice you stick inputs well feel crisper?

Looks like yours is very close to being trimmed. You need to let off the stick for like 2 sec see what way it wants to drift then trim it out. You well never get this or any kk to hover with out drift...period

Ok, I feel like I'm going crazy.

Crash and broke some props this morning, nothing unusual, but after putting it back together it's barely flying. The most obvious problem is that it won't yaw left, but the motors respond as they should on directional changes. I've gone back to square one and reprogrammed and recalibrating each ESC and the problem persists. When attempting to yaw right m1 will spin faster and faster, but m3 will not even though on aileron left it will speed up as normal.

Any ideas?

Mixer editor is normal, motor layout is as expected, receiver check is normal, and sensor test is normal.

KK 2 board set up

can anyone explain the abreviations used in setting a quad copter control board
such as "PI" - "I" etc.and so on. I am very new at this and would like to see a more detailed user manual for "newbies" Chinese manuals seem to be written
in a strange way.
Tnx for reading

did you switch M1 with M3 to see if the Prob follows the motor?

Thanks for the info.I am using Hitec Eclipse 7 ,the trims are all zeroed out on the kk .As you mentioned ill give it try by reducing all p gains by 5 . and increasing i

I read somewhere p is the proportional gain and i is integral gain

"
In a PI loop:
- P is the correction rate for the current deviation from the setpoint
- I is the correction for slow drift over time "

This morning I flew 2 4400 batteries without AL. I finally got the nerv to play with the board settings a little more and I think it is "dialed in" Flights were only interuped by short stops to reduce P gains then off again, only regret is I didn't take a camera with me. Confidence is high now..... definatly time to chash...LOL

Hi
A few years ago when starting with helis i found this training documents to learn flying them. I've picked them up again this days learning to fly my hexa. There is always something to pick up again even if you've been flying for some time.
I've had a one year break som a little has left my head.
