Q: How to reverse the yaw gyro for a tricopter?
A: Go to the "Mixer Editor" and change the channel (number to the upper right) to 4 where the yaw servo is connected. Then change the "rudder" mix value to -100.
Thanks ! I did it already before I saw your post....thanks anyway. Now my tri is flying already.

I am in NO way trying to insult him. The kk2.0 is a very good flight control but hobbykings QC is not very good that's all I'm saying

One battery used. Dean feeding the distribution board and balance plug feeding the VTx and Camera (Camera is powered thru the VTx).
Any ideas?
My theory is the single power source. Again this is just a theory, if a power dropout occurs, it could potentially affect the ESCs and cause them to fail during flight.

So,I rewired everything and now use a separate dedicated battery pack for the inboard FPV gear.

my setting is

roll/pitch P 55 I 45
yaw P 40 I 40

Tighten the tension on your throttle stick. Sounds like when you use rudder, you are also pushing up on the throttle a little.

Good question. I was just about to ask the same thing. I just updated 4 KK 2.0 boards last night to V 1.2 and I saw that in the drop down box. What is accmod? Do I need it?

I believe ACCmod is the modified v1.2 firmware that I posted about a while back. I didn't notice that it made its way into the flash tool until recently. It enables a faster angle filter which combines the gyro and accel for self-level mode.

Some people have had problems with this modification, so I wouldn't recommend using it except for experimental purposes / at your own risk. The update from KK was that it will have problems with yawing while at steep angles. It can also get "stuck" at an incorrect angle. I have made one other minor tweak which solved the second problem. I will upload a video to explain the problem and the fix.

Short answer: Use stock v1.2 firmware for most reliable option. ACCmod version is modified/unofficial and experimental.

i asked last week and never got a anwser. I just assumed the one with out acc mod did not have the trim function in the autolevel menu. Then my quad went in, so when i rebuild im going to flash it with the normal 1.2 and see what the diff is.

if someone has it flashed with the v1.2acc mod, reflash it and see if that trim option is in the 1.2

If people would just read this thread before posting, then the same questions wouldn't have to be answered over and over, thus making the thread an order of magnitude shorter!

Thanks scolton, i have the 1.2 ACC mod flashed on mine, not sure if you seen my video of what mine would do when AL was enabled.
With it at stock P gain at 20 and stock I limit at 20 in the AL menu the AL was very unpredictable as seen in my video. If i zero'd them out, it would hold level perfect. down side was i had not control. Once i started bumping up the gain and limit the the pitch or roll(or abit of both) would compond) with it at 20 it was a pretty fast and sharp bank. Enough that ifit happned in that room you were in. it would of Prob been out through the glass window


I wanted a bit of control, like on the stock FW from HK as i was planning to use it mainly with a camera. Not to bail me out of a sticky situation. usually when something goes wrong on a quad, it happens that fast you would not be able to pull the switch lol
I can see the benefit of helping people new and trying to learn though.

Now you have me wondering it the FW 1.2 "acc mod" is causing that.

Diffidently be flashing it with stock 1.2 when i get my replace F450 arms.


Re-post of the video. Cause I'm sure there are people who have not read every last word of this thread!

Make one, the KK2 firmware is an open source project after all.

How is possible people don't know what they do flash in their kk2.0 board?

Did LazyZero add your hacked firmware in his tool/database?

If people find only from the firmware from official source (that is a post here from mr KK) these ambiguities are not possible

Ps: let remember that your hacked firmware is a nice experiment, but it is nothing else then code done by mr kk, that is uncompleted and consider not stable by mr kk, for this reason it is only in the source code , commented out, but intentionally not part of the official firmware ... as mr kk said about, the problem is a yaw input in special attitudes in autolevel on, may cause undesired results

The code is open now

But there is no community working on it ...

Quite different compared to multiwii or other real open source projects

Ps: but Mr Kk, alone can do software/firmware better then most of the internet open source communities
