I'm still tuning my quad when I get five minutes here and there.
My latest test had a lot good going for it. I sorted out my terrible yaw spin with some new sturdy motor mounts that I made. Now at least I know that my props are all at least pointing in the same direction on my go talon frame.
I also reduced my vibration right down with some motor balancing.
So, took off lovely and stable in auto level mode (what's it called now in mw2.2?) and I mean ROCK stable. But it then ifts gently away and just won't respond to any directional control.
One thing I did notice is that when throttling up, the motor speed just ''snaps' on from idle rather than smoothly.
It sometimes does this and I can't seem to figure out why it does that from time to time. Doing a hard power down and restarting often returns it to normal operation.
I guess that is the problem behind why my quad just wandered off like a disinterested cat.
Anyone else seen this kind of thing before as I've had it ever since upgrading to 2.2.
Running on multiwii with 30a turnigy plush escs and all calibrated.
Disinterested quad
Re: Disinterested quad
Just ran it again strapped down to a workbench.
I think I'm going to dismiss the sudden snap in motor speed when I increase the throttle from zero as simply my idle speed being fairly low and that being the lowest speed that MW wants to run when the throttle gets out of the safe zone.
I'm able to rev the throttle fairly smoothly, and indeed saw some reasonably good throttle response when trying to fly yesterday.
The motors all react briskly to roll/pitch in both stable and acro modes... so why the lack of response in the air?
Scratching my head here now.

Re: Disinterested quad
thats really odd, what kind of vibrations are you seeing in the gui? do you have bluetooth, so you can watch the gui while its in air?
Re: Disinterested quad
I'd say vibrations are okay. I posted some images of my before / after traces from the GUI after balancing the motors.
Now... one thing I still have left to try. My flight yesterday was to try to see how my new motor mounts worked (pass) and how the flying experience was after I'd reduced my vibrations BEFORE I applied a filter.
So, my next step is going to be to apply the software filter and see what that does. However, I'd be pretty surprised that the level of vibration that I'm seeing is enough to totally mess up the controls.
If that were the case, wouldn't I then have problems with the auto-level? While it was in the air it drifted gracefully off, and TOTALLY level, with no yaw drift that I could see eifher
My nice foam rubber feet were a little TOO effective though. I took a hard landing and the bird did a huge bounce, landed upside-down and I bent a prop! Kinda looked funny anf I have loads of props, so not too annoyed with that.

Re: Disinterested quad
yeah, i have to be careful of that as well, i use tie straps as landing gear, super light but very bouncy
Re: Disinterested quad [SOLVED]
Hang on: RC RATE = 0 ????
D'Oh.... set it to 0.9 and now it's listening to me.
Grrr, wish I'd noticed that sooner. Had a brilliant lunch-break actually being able to FLY the thing meaningfully for the first time since I put it together over Christmas.
Now to key in those PIDs and trim.
Add that one to the noob FAQ.
