You're flying the APM2?  You probably already know but generally consensus is that the slow accumulating lean is due to vibration.

Ah, yes, see my numerous previous posts, graphs and logs on this thread. I have vibe-insulated the c**p out of the quad/motors/props/board, tried 7 different types and densities of foam and rubber to try insulate the board, magnetically balanced the props, mounted the motors on rubber pads, etc. Spent two days trying to sort it out. Have only had sudden death lean and slow accumulating lean with APM2.

I have now shelved APM2 and put APM1 back on my quad. Based on my difficulties trying to reduce vibrations for APM2 I predict there's going to be lots of unhappy people when they install their boards. Hopefully I'm wrong!

I think that Chris mentioned v2.5 attempting to use some S/W filters for the APM2.  Fingers crossed.

I have had the "leans" with my APM2 setup from the very beginning.  My larger motors are difficult to balance as i have them currently.  It's improved recently with v2.4 and better APM isolation on my part, but it's still present.  I can fly the quad much easier now, but I don't believe it's ready for FPV or aerial photography yet.

Do you do fpv already? If not, get the '$100 quad' with the cheapest camera you can find, kk controller and go for it, you will crash, better on that than the ardu. But you'll  be having amazing fun, I'm loving it, been doing tree runs and everything :) Then when the day comes to stick it on the ardu, firstly the ardu is intact and ready to go, but secondly you've got bit of understanding of whats going on but now with all the capabilities of the ardu, FPV autoway point (despite my awful tuning) is an almost pant wetting experience :)

And I'm one of those 'extreme sports' kind of dudes....

My FPV flights from Arducopter, V2.3! >Here

While not strictly FPV in that video I did two batteries on the next two flights with FPV goggles. Love it!

Graham, did you ever try putting a metal plate between your APM and the frame?

APM/pad/plate/pad/frame ???

Was last: APM2/softerfoam/softfoam/thinply/hardfoam/frame

The thinply isn't good enough.  It's too light.  And with the hardfoam, it's probably not doing anything for you.  Try a plate of aluminum.

I don't KNOW this will work, just an idea to try.

To tell the truth I have given up on APM2 for the time being, the amount of time & effort  required to try insulate this thing against vibrations for me is just not worth it, I was getting no-where. The correct insulation window must be so small and with the hardware variations out there, wow. I'll come back to it in a few weeks when it's matured a little.

I have put APM1 back on the quad (on the same mounts), did some tuning and had 4 very good flights this afternoon, off to do some FPV tomorrow.

try this Gaui system plate with Gaui foam isolation too, juste make four hole in top of your quad and insert the silicone robber, it wok fine for me :)

How does that work?  I think I have an idea, and if right, it's pretty slick.
