Thanks guys.
Being a stickler for perfection, the little wobble I get is doing my head in.
I have tried a bazillion different settings to try and get rid of it, but no luck.

What pid controller are you using?

Lee · Post by **Lee** » Thu Apr 23, 2015 4:53 pm

At the moment, 3, but i have tried 5 as well.

The only ones I've had any luck with are pid 0 and 1. All the other controllers give oscillations that I can get rid of.
that could be due to the 5045 props I'm using, I've read it can be difficult to tune with 5045's.
From watching your video I would try decreasing the roll P a touch and increase the d a bit too. If it starts to feel slugish when you have increased the D, try increasing the rate for that axis until you like how it feels.

I've spent countless hour pid tuning and am pretty happy with it. I'm just getting a bit of roll wobble at low speed, hover and fff are awesome and low speed feels good but there's wobble in the footage.

I have lowered the P roll gain down in small increments, until I got to 1.5 with no effect.
I started from scratch yesterday again, and think i'm getting closer. I have roll at 1.8, but it seems what I think is high frequency wag, may be I gain, not the P gain.
I'll test again tomorrow.

Good luck mate I know how frustrating pid tuning can be.

Beautiful walk with my wife today, just along from our town.
Had a quick flight with the mini 250.

Found an old motocross track behind the town.
Had some fun with two local riders

That looked like loads of fun Lee.
I have done the same with my son on a BMX track but obviously at a much more sedate pace.
I bet the guys were surprised at just how quick that little quad was.
Would love to have seen some external footage of the quad going through that dust.

You seem to have developed a bit of oscillation on the roll axis.

Looked like great fun Lee, you certainly beat those 4 wheeled kind around that track. Awesome flying

That's some cool video Lee. How do you like your four prop.drive Quad Vs the four wheel drive Quad? Lol. You always produce excellent videos once again Lee. Keep the videos coming. I enjoy them and others as well.

That looked like awesome fun, Lee! Nice job!
