Initial Gain Settings

[mbsteed]

I just wondered if folks could give me a good starting settings for the gains with the latest firmware. I have redone all the wiring on my octo and want to test it but am a bit gun shy because the last two attempts ended up with two broken arms. Once it was up in the air it was oscillating and out of control. I hope that the rewiring fixed the problem. This is a Droidworx HL Ocoto with no camera gimbal (yet), Avroto 2814 motors, 13 APC props, Maytech 30A ESCs, two 4S batteries (6000 mA). I noticed that with the latest firmware upgrade the default gain setting went to 400%. I know it is different for every ship but I want to make sure that I am in the ball park with the initial flight with the latest firmware. Should that be my starting settings?

I've found these to work everytime i put em in

130-130-110-120

atti 80-80

How you know what to look for. if your a solid flyer, you'll want to do some full power punchouts in manual. with onboard cams is the only way i can make what i'm seeing, but your looking for no oscilation or wobble. if it wobbles fast, gains too high, slow wobble, too low. then same thing in atti, full throttle punchouts should look smooth without motor hunting or wa,wa,wa,wa sounds followed by wobbling

atti punchout at :10, manual punchout at :48....... this was all with a bad bearing in 2 motors.

...full throttle punchouts should look smooth without motor hunting or wa,wa,wa,wa sounds followed by wobbling.

wa,wa, wa...hmmm?
Does it sound like zip zip zip,... like a really fast couple of loud zippers?
I had a zip zip zip, with a wobble.

So, there is a correlation between gains and unstable "zip, zip, zip, wobble" punch-outs?
My Jr 9503 has sliders that are sooo easy to bump.
I wish they had slider position lock, just like my other equipment from other hobbies.

...Maybe I can tighten the JR9503 slider screw to tighten up the easy movement. 'errr!
...Maybe I can cut off the plastic lever to cut down my bumping or leverage of the slider....hmmmm?

i use one gain wire and got it on a switch assigned to gyro channel. i leave the manual gains like above, but have atti on the switch. when you set it up, put the gyro gain to 80, goto assistant assign it to the x1 or x2 and type 80 in atti mode, now when you move that ( i use 70-80 and 90) it changes to those exact number. when it's dead still out, i'll go up to 90, when the wind starts to blow, i'll go down to 80 and when it's howling, i lower it to 70. my point is theres no way to screw it up and you know exactly where that number is and can easily fine tune in the field using the gyro gain window. theres no guessing

oscillations can sound like a lot of different tones, but the one thing thats common is the motors reving up and down and the wobble. if you get too low in manual gains, it'll want to drift off balance real easy, too high and it oscilates with full throttle
