It arrived fast and as pictured (with WiFi daughter-board and SD-Memory-Card). It appears to be generally good build quality for a cloned FC from the outside (metal case, etc.).
From Windows MissionPlanner, I loaded: APM:Copter v3.4-rc5On the PixRacer (BG clone) hardware, it's identified as:
APM:Copter v3.4-rc5 (0d9d101f)
Note: Due to a recent IMU hardware issue fix in code, this might be the first firmware version that is working 100% for this particular FC.
After firmware upgrade to this version, my PixRacer still Connects to MP and seems to operate normally for a benched FC with only an USB connection. Even in this minimal state, I went ahead and did some minimal Compass and Accelerometer calibrations. The PixRacer continues to operate properly in MissionPlanner's HUD.
I will try some more elaborate bench-test configs, and post about those test results later. My initial opinion is favorable.
