Really not happy with the stabilization at all, it wobbles like fat tire, unresponsive like a cat.
oscillates like a horny man D:.

and i dont think its on the P at all, tried going from 0-5, no changes D:
i tried everything

My accelerometer keeps resetting it self

I would try to make a video but its really hard to get a good shot.
I had very similar symptoms. Have you tried multiwii? It's stock settings were a lot more stable for me.

It's also been suggested that RATE PIDs are changed rather than Stabilize PIDS to any effect on stability in MPNG

Forgive me if you already knew about that.

I didn't know that. I'll certainly have a look that when I get the replacement board.

I have a small mini-B female to to micro-B male tail I was going to use to pull the USB out to one of the copter arms. Do you know how feasible it would be to snip off the micro-B end & solder the wires to the board?

USB seems to just be Gnd/5v plus a 2-wire, differential data interface - so shouldn't be too hard?

As I have a replacement board on order I'm happy to mess with this one!

It would really help me to know a couple of things before I try to install this on my FlameWheel F450 & try to get airborne:
  • There are many, many parameters it's possible to fiddle with using the Mission Planner. Before making that first flight, is there anything I NEED to fiddle with, apart from configuring the flight modes & the Tx controls if I am using a brand new copy of the latest MPNG (I already did the changes in the APM_Config to set it up for the AIOP)?
  • The USB connector fell off the AIOP for the second time tonight, probably terminally. Can I do everything I need to do to get this flying just using Mission Planner over bluetooth?
  • Is it possible to load new versions of firmware (MPNG) using bluetooth, or will that have to wait until my new board arrives?

I'm not yet familiar with the detailed config of MPNG so knowing what I HAVE to setup, & what I can leave until later, will be really helpful.
To get a grounding as to what does what when you play with your PID's check:

1 - these vids out, they were most helpful to me

MegaPirate PID tuning - rate (acro) (3 min 20 sec)


MegaPirate PID tuning - stabilize (acro) (1 min 45 sec)


MegaPirate PID tuning - rate (acro) (3 min 20 sec)


2 - In regards to what is MOST important read the below, it will cover 95% of what you will encounter

http://code.google.com/p/arducopter/wiki/AC2_Tweaks

"Basic performance troubleshooting"....

3 - Further on the same page...."In flight tuning"(My number 1 favorite feature) If you have a the ability to assign channel 6 in the mission planner to a variable pot on your radio do so, these will enable you to tweak your settings live at the 'turn of a dial'

Golden Rule: Tune 1 thing at a time, until you know what does what

My approach I use in all my multis:
Dial in Rate P (This controls how stable it will sit in the air, its also the platform for all other settings, so take your time)
Dial in Stabilize P (This controls how sensitive it is to your input)

The rest of the settings is just gravy, practice plenty and it will come

Cheers!

The frame on mine was solder to the PCB, could have done with a bit more solder but still never had any problems with it.

This has probably been answered before, but if so, I haven't found it. How do I hookup my CN-06 GPS Receiver V2.0 to the board? I'm pretty sure I have to change out the 4 pin connector it comes with, but then where on the board does it go and with which connector? Pictures would be great if available.

It hooks up the same way as the V1, TX to RX2 & RX to TX2:

I have a gps with just a ground. 5 v and tx pin. That won't work? The board needs to transmit to the gps too?

It will work if the GPS module is configured to all the correct setting, Baud,Hz,etc.

Thanks for that - I'll work through them.

Regarding connecting a cabled USB socket directly to the broken PCB, I believe the important connections are as shown below?

Great, i just wait for the 1.0, and here is the newest, better version?
What is the difference? I hope not so much.

I've 1200 kv and 8x4 props in a 450 frame and the defaults are very good although the auto level might be a little strong. Maybe if you could post a video of how it's wobbling.
