Another Video need some advice on how best to set the gain

[Dominic]

Hi all
Just to say a very big thank you for your advise it has helped me loads!!!!!!!!!!!!

I am going to programme the Esc, to medium and see how I get on, also I really think the bigger the prop the lesser the gain!! I have not had the weather to work on the gain but I have balanced the props now. I love the amount of lift I get from the 13"s so I will stick with them for now. I will post my final settings as soon as I am happy with how it's flying.

Cheers again Dom

Ps would you guys like some more videos????

Oh yes, get them on Dom The videos that is

The smaller the prop the better the response but less lift...

Your set up is exactly the same as my own except for the mount and props, I'm using AV200 360 and what I do have and seems to be a problem is exactly what you pointed out "prop size" I'm using APC 13" 6.5e and my stability is poor (just as in the video posted here) so I think I will go for the props you have. What is you stability like with 11" props and is there plenty of lift? do you have any video footage to look at taken with your AD6 HL

I just took my AD6 out for its first test flight with the new ESCs. Initially I was using the same settings I started with before with the other set of ESCs, turns out with all the motors running at the same speed it looked awfully rubbery in a hover. Came back in the house and bumped the basic pitch and roll to 280 and dropped the ATTI to 80%, MUCH steadier on the second attempt. Got a GPS lock in something like 30 seconds which never happend before with this WKM, tried out the position hold and it worked quite well with these settings. What I find interesting is how responsive it is now, it NEVER flew like this with MK electronics and still using the same motors and props, far more agile than before and the altitude hold looks like it's hanging from a rope.

Too dark and cold to do much more with it tonight, I'll have another go tomorrow in daylight to get the gains dialed in a bit better and then I'll hookup the old AV130 that's hanging under it. Not really useful for video, I use this one mainly for still shots as it has the old Hyperion servos and it just doesn't have the speed to do smooth video work but its probably worth another try with the WKM doing the compensation rather than an MK flight controller.

Hi All

I will post some more videos as we carry on. I was wondering about the centre of gravity and how it would be affected by the our 550d moving around in the gimble, any thoughts?? Also don't forget we are running the AV130 360 gimble. I will say one thing about the gimble, it's bloody hard to mount tx, battery and vr on it!! Keeping the CG, at the same time is even harder!! Well in time I hope.

cheers Dom

Those pitch and roll gains seem high, what size props you using? My GPS lock takes unto 5mins at times, I can't think why higher gains would reduce lock on times, is this what you are suggesting?

No, gains have no effect on GPS lock times. This WKM has previously taken a couple minutes to get GPS lock, now it's locking in a minute or less, layout of components is not much different than it was on the other frame, no clue why all of a sudden WKM GPS works almost as good as my MKs.

Pitch and roll gains are what they are, some like a looser feel to the controls, others like a more locked in feel, high basic gains on the large multis give it a solid locked in feel. Actually 280 isn't that high, on the CineStar 6 the lowest gain setting I use is 320. High basic gains with lower ATTI give much better stability in wind, I can record useable video with those settings where it would be unusable the other way round.

Hi Ken

Thanks for that, if the wind in the UK drops to anything like low enough to fly I will get out and dial in my AD6 heavy lift, for now I'm sick of waiting to get back out, the winds have been up to 102mph in places and between 60-70mph here with average wind speeds at 25mph for the past week, not good. I'm swinging 13" APC props at the moment and can't seem to get it dialed in, although I haven't had gain as high as 200 yet and not enough time in the air, if higher doesn't work I have some Groupner 11" 5 props on order to try and help stability.

Good flight on Sunday. Following on from the advice from Geoff we changed the speed controller timing to medium and set the battery type to Nixx.
Gains are now up at 180% and Dom noticed a big difference in the right direction so we will try 190% on the next flight and see how it goes.

I've done a quick video comparing 150% and low timing with the current settings but its a bit short so don't know if it will be any good. The left hand video is the current setup, you can see a slight difference between the two, the previous set up wobbles more and with larger movements when in GPS whereas the new set up is much smoother.

Getting better , take it up some more till it shakes then drop it 20% also lower Atti gains Try around the 70 mark .. And keep Altitude where you have it if its holding well .
And keep the vids coming

Had a good run the last couple of days but we are still getting the two white lights error flashing up. If you hold in a hover it seems fine but it comes on with any manoeuvring, after hovering for a few seconds it disappears again. Weight distribution is perfect and configured correctly on the DJI. Could the disturbed gain settings cause this error?
The IMU is mounted firmly on a double sided (thin) foam pad, the GPS and IMU are facing forwards and is straight so we are not too sure what's causing it.

Is it white or yellow flash/spark.

If White doppel spark:

Attitude status fair

If Yellow:

Doppel spark indicates that you are not centered, also Throttle, so everything is fine. Se page 45 in the latest manual.

Sparking indicationsof,,are: [FONT=Arial,Arial][FONT=Arial,Arial]Single spark[/FONT][/FONT][FONT=Arial,Arial][FONT=Arial,Arial][/FONT][/FONT], all the sticks return to center, multi rotor hovering; [FONT=Arial,Arial][FONT=Arial,Arial]Double spark[/FONT][/FONT][FONT=Arial,Arial][FONT=Arial,Arial][/FONT][/FONT], stick(s) not at center, speed command is not zero.)
