DJI Naza Firmware Upgrade to Version 3.12

This month DJI has released two new versions of the Naza firmware. I wanted to upgrade from my existing version (2.02) to the latest version (3.12). I had read about better stability with the latest version so I wanted to put together a comparison test. I was skeptical that I would notice a difference, but the results from a basic indoor flight test are pretty astounding. I was very impressed!
There are a few gotchas that I ran into when doing the upgrade and I tried to capture those in the video. The most surprising part was when the Naza Assistant software told me to unplug my Naza FC for 10 minutes. I have no clue what that was about but went ahead and did it. The IMU calibration process is much more elaborate in this version of the firmware and maybe that's what accounts for the much improved flight stability.
Also, since I was upgrading from 2.02 I actually was two releases behind. Here is what features DJI lists in each of those releases:
Version 3.10
-New attitude stabilize algorithm, provides better flight performance
- New flight control feeling(takeoff is more stable and easy; flight will be more smooth)
- Auto course error compensation
- Support octo-rotor; Add protection for Hexa-copter, octo-copter when lost one motor power
- Add IMU advanced calibration, sensor error monitoring and protections function
- Support PMU module with CAN BUS port, could support iOSD, GoPro gimbal and Bluetooth LED module, and so on
- Increased demand for GPS signal strength, increased the compass interference monitoring and warning, maximumly reduced the effects of magnetic disturbance
- Add new LED informations
Version 3.12
- Add Receiver Advanced Protection Function.
- Fix the problem of Transmitter mid point deviation and travel asymmetry. Add mid point checking when power on, if mid point deviation is too big, motor start fails and there is Red LED indicator to warn you.
- Optimize stop motor in Intelligent Mode, the criterion of stopping motor changes from under 40% throttle stick to under 10%
