This gyro is being reviewed by MHW as the Phoenix GT9 and from what I have learned they think it is a good 'budget' system.
The 'Chaos' goes under the Phoenixtech brand name of 'Flasher' for Europe, I bought a 600 ESP version for a scale build and found that there were quite a few design issues. Holes too small, warped main and tail drive gears, missing thread lock to name a few but for it's price it is a reasonable enough mechanics. Changing out a few components is not too big a deal for a clone but some clones are a lot worse than others so choose wisely!
Nice steady work on the build so keep us all updated.
Just a reminder - rub down those sharp edges on the frames, the could cut through a wire in a single flight if you get vibration.
