Diagnosing Quadcopter Flight Problems

Strange behavior in my Alien last night. Finally tried a test flight of the new setup with my gimbal mount forward and battery back a tiny bit. This is to attempt to get the props out of the video/photo frame.


On take off my bird would not yaw clockwise, only counter. And it would not hold position. Luckily I was able to land it without doing any damage as I had minimal control. I recalibrated the GPS/compass but still issues. A look at my motor outputs (photo below) shows the clockwise motors are at a much lower output than the other two.

Because of this event I decided to upgrade the firmware on the MiniX flight controller and will probably go through all the stick calibrations again.  More testing soon.

Unboxing: New XAircraft MiniX Flight Controller with On Screen Display (OSD)

Today we get the first look at the new flight controller from XAircraft, the MiniX.  XAircraft is known for their high end controller called the SuperX, which I have installed in my large heavy lift hexacopter.  The MiniX is a lower price point controller, meant to compete for the market of small and mid-side multi-rotor copters.

The Box

Looks a little like the old Apple OSX DVD packaging…


First Opened

When opening the box, this is the first thing one sees.


Goodies Inside

The GPS puck, OSD unit, flight controller, GPS tower, cables, misc items included in box.  Included but not in this photo are some pieces of double-sided tape and the MiniX quick guide.


MINI Sized

The MiniX really is mini. It is tiny mini. Below is a photo of the three primary pieces, the OSD, FC, and GPS, next to a USA quarter for scale.


MiniX Review Soon

Soon I’ll be installing the MiniX on a 680 sized foldable quadcopter and doing some testing in preparation for a full review of the MiniX system.  Stay tuned.
