Interesting...Im also new to hobby and bought a very similiar kit from an after market supplier...Looks exactly the same...Dont know if I can answer your question but I ll tell you what i did. Same issue, the copter is totally uncontrollable. I also thought was gyro. So i put unit back into original condition out of box and worked great! I have systematically added component by component and here is what Im seeing.

1 in original condition out of box unit flies great
2 I added skids and tail section.....really wants to fly backwards (tail heavy) so add a light weigh tail section I got at store. Carbon fibre tubing and carbon tail section.....unit flies great
3 I added motors (extreme 180) and unit hovers but wants to rotate counterclockwise. I turn trim all the way to end and still rotates! doesnt make sense to me
4 I put original motors back in and now add the same exact blade set up you have....thing flies uncontrollable!!
5 Ive tried adjusting blades, Ive trade adjustments in gyro/reciever...to no avail
6 So Im kind of in same position as you. Ive sent email to company tonight..late back east so dont imagine I will hear for a few days.

I will watch your post...if you find solution off line can you let me know as well? Ive spent days on this and many trips to hobby store and they cant figure out.
