Big help man, thank you very muchI So to conclude, is it safe to say 1) acro P&I settings have no influence on flight with self-leveling on, and 2) "I" setting in acro is attempting to hold attitude established by stick input whereas the implied "I" setting in self-level is always just the same as attitude when armed on the ground.....hence no I setting in self-level menu? My lightbulb moment awaits....
Yeah, it's tough to say but you could have bad vibrations affecting everything. Your P is too low and too much I can kill your control too. Just set the PI to stock settings and only decrease the AL P gain down. You won't have a snappy autolevel but it shouldn't shake. Flashed ESC's will help a lot too.
There's not much to do there. Height dampening is only using the Z axis accelerometer to try to reduce drop in forward flight. I've never liked the craft trying to control it's own altitude unless there is a barometer. I always set mine to 0 and adjust with my thumb:)
Are you getting vibrations? Have you balanced the props and made sure your tail control is nice and tight? I've had the tails shake so bad it causes flips on Tri's before. I'm generally not a huge fan of them for that reason.
I've looked all over for this explanation on the KK2 board, so glad you posted this vid, helps a bunch, thanks! I also question as did "Nathan JR" what about the I settings, mine are at "zero" I'm guessing, that's a NULL setting making it inactive? Thanks agian for sharing Your knowledge..Awesome Vids! :D
Fantastic! I am just getting my quad going and when I can formulate a set of questions I will get back to you. Equipment as Follows: Turnigy Talon 550 frame Turnigy 2836 1100KV motors KK2.0 FC board w/v1.2 Qbrain 4X 25 amp ESC Orange 6 channel receiver LiPo 3S 1300 mah power Spektrum DX4e Transmitter Great job with the videos. Regards, Captain David A. Johnson
Hi!! GREAT VIDEO!! Can anyone help with my problem-Its my first quad build using st360, stock motors, kk2, power distribution board, 2200mah 3 cell and 4 channel hk transmitter and receiver. The problem i have is the quad takes off but then comes back down, every attempt is the same? Only reaching 2-3 foot off the ground. Weight is 850 grammes. Thanks.
Very good and much informative session!!!loved it!!keep going I ve a hk x525 frame, 30 a generic escs, kk2.1.5 FC, batt 4000 amh 3s!!can you pls saggest best appropriate motors for the same? Thanks in adv
great video and explanation have just bought an HJ 450 which the seller dumbed down for me so now i will be able to perk it up abit as i get better at flying it. All this Gain stuff was a total mystery to me until i watched your video i have Subscribed to your channel so hope you will keep posting this sort of information GREAT JOB :)
Hi..very informative videos. On my tricopter, I will fly away from me, then I will turn nose in toward me, but the copter snaps back 180 degrees away from me. No matter how many time i turn toward me, it snaps back. What do I need to change?
this is the most concise, no BS explanation I've seen yet. I wish all YT videos were like this instead of 5-10 minutes of a guy wanting to hear himself talk until he finally gives the 1 minute demo you came for where you still don't gain any knowledge
Hey buddy! Great video, truly helpful for those of us trying to learn how to properly calibrate our crafts!. I have one stupid question... the word "overshoot" keeps popping up and I don´t know what this means, and neither does my common sense like with other words (English is not my mother tongue!) Could you enlighten me as to what "overshooting" actually is? Thanks a lot, cheers from Argentina!
I never tried the autolevel ,I get a sk450 by turnigym, after this video my quad is really stable, I even fix the rudder unstable problem, great thanks
cheers for this..... and for information on one of your forum posts where you recommended that the original poster should do a factory reset on his KK 2.0 board, and attempt to fly the quad again.... I followed your info and now my quad flies as sweet as a nut.... cheers buddy...
I wanted to know the basics about auto level. Like there are two modes: Stick and Aux. I figured out stick was easier and then tried to arm KK2 while pushing the right stick in all directions until I finally got it on. It is off by default and there was no place to know how to turn it on, not even here.
i just solved this for my quad. Not sure if you are using 3.5mm bullet connectors but one of those on my front left motor was bad. NOT the solder.. the bullet itself. It was the male end. If the bullet rotates too easily, replace it. Not sure if this applies to you but hope it helps.
Definitely loaded the tricopter model on the KK2? How long before it flips? Checked all ESCs? I built the RC-Explorer tricopter, no balancing on props or motors, basic tail tilt mechanism. Only time it has ever flipped is when I was messing with the auto-level settings,
flash your ESCs, make sure the axis are coupled, make sure props are balanced, make sure ESCs are all calibrated as described in the instructions or here in one of this guys great videos. My stock turnigy ESCs did ok. My Blue series had to be flashed to get rid of the jitters.
My self and my buddy both have a tricopter, both experienced a roll to the right... he thought it was loose connections, I discovered in my basement that my battery was going dead... SO, keep the batteries charged!!!
Thanks for the great explanation! I previously had totally the wrong idea about autolevel P limit... I thought it was just the denominator in a ratio with the gain. Thanks!
Great video. Hey would you know why my KK2 450quad always reverts back to drifting even when all my settings prior did eliminated the drifting issue, roughly after 1min of flying time, my quad starts to drift again and it gets worse the longer I keep it in the air, its bugging me big time, could you please let me know if there is a solution to this, or has anyone here experienced the same problem and was able to fix it. cheers.
Thanks, your kk2 videos are great! Could you do one that shows the history of the f/w. For example, what is the difference between ver 1.5 and 1.6, and explain which menus have changed or been eliminated or added. Also.. When making kk2 board videos please include the boot screen that has the version displayed or note in the title of the video, the version f/w the video is about. thanks again!
Very informative. My problem is that the quad tries to flip over when I'm activating self level. If it's in flight it will promptly tilt and go straight backwards and into ground. If I'm activating selv level while on ground it will try to flip backwards when I'm increasing throttle. Adjusting the trim and P gain/limit doesn't seem to affect this at all. I'm using version 1.5. What can be wrong?
Just remembered ( what must be the MOTHER of all stupid questions for a noob to ask..sorry ).....could someone PLEASE explain to me how the translation between the trims ( etc ) when done on the actual KK board takes place ? ( say for example )you set your roll to 20% LEFT on the actual KK board on the quad...then when you turn on your radio, shouldn't you have to COMPENSATE for that 20% ? cant get my head around it! both the quad AND the transmitter have trim controls I'm confused!
I hear a lot about " flashing the ESC's " - I'm a complete noob at all of this so the more information the better...I know what an ESC is and what it does...but how and why would you "flash" one? Also, ( while I'm at it ) - there have been people saying that there are versions of the KK 2.0 board that have "dud" firmware and you have to either get an earlier version of it or up-grade it... Has this problem been fixed yet? and WHICH version of the KK 2.0 do I look for that's NOT "buggy"?
Frustrated Please help.. I had a X525 quad, KK2 1.5, Moongel damp. NTM 2830 750kv,GemFan Carbon 10x4.5 balanced, Dynam 30A ESC, 2650 4S, GoPro. FLYING GREAT. Until a signal failure, sudden death. ONLY damage was to the frame... everything "checks out". Now...have switched over to a TBS Discovery Spider frame "Replica" Same everything. the quad will NOT fly without a huge roll oscillation, and frequent flip and crash. I have changed all my PID's to several extremes and cannot find a balance point
Hello, i am having problem in test flight. When i turned on it rotates randomly . Could u tell me about pi settings that i could change. It is difficult to control landing, either it goes too high or crash.
I found of later what was wrong. I was using the 'gear'-channel to turn the autolevel function on/off and it turned out that on my radio this switch was also linked to the 'aileron'-channel (I used this radio with an airplane earlier and the grear-switch to turn flaps on/off). When I corrected it everything worked fine, and still does.
Wow.......i've pretty much just ignored the ACC settings up 7ntil now since its not really listed in anyones initial setup videos for the kk2, but damn it if you didnt make me smack myself in the forehead that it took setting up a gimbal to figure it out.....great simple, concise, & logical explanation for autolevel & acc setups.....THANKS!
to arm the auto level using the stick, hold your throttle at mid level right, and you other stick to bottom left, The Aux setting is for when you want to assign Auto level to a channel switch, so you do not have to use the above method but this requires a separate channel.
Nice video. Unfortunately I speak French and I do not understand well your advice. I can not pay my kk2 for my 450 Quadcopter .. P Gain, P Limit, Limit I Gain or I are values that I do not understand, even with the "official" instructions .. Can you please help me? Thank you so much!
I have had to dial my p gain down to 9 to stop the it shaking while setting up the auto level, giving me virtually no stick control, even with the I gain way up high. Evidently my issue lies elsewhere, but I don't know where. Any suggestions as to what I should do? thanks
You must have heard me wondering why nobody had explained the way you just did. Thanks for a much better explanation and demonstration of PID settings. I wish you could explain some things about some of the Multiwii GUI functions now.
I noticed you sell preflashed escs on your website.. I will definitely be purchasing 3. I have a question though, I just ordered a kk2 board, if it comes with 1.2 firmware as advertised would you be willing to flash it to 1.5 firmware for money?
Can you do a video explaining the p and I gain and limit for when you're not in auto level? I have a hard time flying without auto level, my quad feels very fast and I can't fly it... Maybe I'm just not good enough yet? Thanks
I upgraded from a kkmulticopter board to a kk 2.0 board and the auto level is amazing. Thanks for explaining the trims, I was trying to trim on my transmitter and was getting no where, flies perfect for FPV now.
FINALLY!!!! The KK2 Explained!!! This was an Awesome Video, I'm looking forward to dialing im my Tricopter with your Esc's on it. Thanks for this Much Needed Video, looking forward to all of your future Vids!!
it happened to me too, i found that it is because i did not calibrate the ESC... Google search on how to calibrate ESC on KK2.0 :) Don't use the receiver calibration method, only use the KK2.0 Method
If i use a different battery does it affect the settings? because I usually use a 3s lipo but when i use my 4s lipo I get this 'high speed oscillation' you described in the video? HELP !!!!
Thank for the video. Very quick, easy to understand and straight to the point. Definitely appreciate the explanation. I would love to also see one on height dampening for the kk2 as well. Thanks again!
I really needed this. I have been trying to get some oscillations out of my quad, but I was only working with the pi editor, when I needed to work with auto level adjustments. Thanks and liked.
A good way to eliminate this problem is to use the voltage sensing of the KK2.0, you will need some basic soldering skills... go google it up on how to use voltage sensing on kk2.0
When in Acrobat mode, when you tilt forward, and let go of your stick, it continues to go forward, in Auto level mode, it reverts back to flat, or at least to your calibrated position
Would you go over the 1.6 firmware? There are several versions out and even has "satellite" receiver ability now! yea baby!! (I would do it but your style of teaching works)
Hey, I love your vids! Can you tell me what should I do when height is hard to control? Small th inputs make quad speeding up in to the sky or dropping like a stone. Thanks!
Great video! I had all but given up on the KK2 because that stuff has made no sense. thanks for the GOOD INFO. NOW... work on that brushless gimble! I am VERY interested!!
I mounted my KK on the F550 frame with vibration insulating foam and velcro, it allows me to have a little 'give' in the vibrations and lets me remove things pretty easy :)
Just got my kk2 for my hexacopter im building.Whats the best way to mount it to my 550 frame ie, hard mounted or double sided foam. Any input would be great thanks.
TheBishonator - a guess on this but since a 4s will weigh more then a 3s it will shift the center of mass and change the flight characteristics of the craft.
This is exactly the kind of video I need cause I'm looking att building my own quad with the KK 2.0 board and 450mm size frame. Very good information, Thank you :)
Fantastic video, great explanations. I watched hobbykings tutorial and they had the pgain at 100, which gave me the high speed oscillations with the overshoots, would take off well but after 3-4 seconds the wobble kicked in, but thanks to you I actually know what im doing now lol.
On behalf of all Noob and intermediate flyers I thank you for making something so many people have made complicated, look simple. After much reading and practice I managed to get my acro mode perfect but my auro level has always been rubbish and I couldn't work out why. You video showed me the right way to tune it. You're a genius
THANK YOU for the best explanation of P Gains & P Limits. I am currently building a Hoverthings Flip FPV w/ a KK2 and hope to get it up & flying this weekend, thanks to your videos!!
Thank you soooooo much, I wondered why my quad was very snappy when not in auto-level and then whenever I switched to auto-level, it became very sluggish. P Limit!!!!! THANK YOU!!!!! It's gonna be so much more fun to fly now!!!
I tried stick scaling, bumping the gains higher, putting some negative expo on my transmitter, nothing worked, all this time it was the P Limit hahahahaha I was concerned about the quad not reacting fast enough when I try to stop or change directions very fast, it was very dangerous. Now it will just POP!!!!
Hello thank you so much for your time making these video ,but i have some problem and i really need help, as I'm new in these hobby !! so I did all calibrations it need to be done and power my remote on first and the kk21. second. ,and motors still won't move , i don't know why !! and I couldn't get self level on its always off ,thank you for your time
I understand the limits in the PI settings are how much of the power budget this control can use to pursue reducing the error to zero. If you set a limit to 10 it says the control can use up to 10% of the total power budget to pursue zero error. If all other controls are in equilibrium, you get your 10%, but if other controls are making big corrections they get their share of the power budget, first. With 10% power allotment, it might take a while for our control to recover, or take forever to catch up. The control would therefore be out of control, unable to zero the signal error.
