The "new code" its just 'drivers' for MPU6050 that sits on freeIMU, or any other MPU6050 type board... 

There is no change in main FlightControl (acro/rate mode part) code.

Setup like that one will do the same job as freeIMU  ( - compass and baro )

So the apm and the multiWii have basically the same hardware except that apm also has gps. When I construct any copter I first want to fly it myself before any gps mode to measure stability. It's also more fun! It might also true to say that this stability is important for gps hold/guide but that's another conversation.

In the video we can see the multiWii is not twitching and is moving in a very smooth manner. For me this is always the first thing I look for, it brings a lot of confidence but let uis not forget that manual control is our failsafe on all copters so it is also very important.

I think we have seen examples of very accurate position hold without need for gps so I believe the physics and not features are the key to stability.

I am still very impressed with the multiWii project and with Fabio who discovered the new pressure sensor that apm2 is using. I wait with keen interest to see a video of apm2 demonstrating the same stability as outlined in the "2nd" flight video at the top of this blog.
