Gone, gone gone.. I went out for a quick afternoon flight. Did everything as normal. Waited for the home lock, took my time did everything ive done twenty times before. I noticed immediately the craft was acting weird. it wouldnt keep elevation, started yawing, I immediately double checked all my receivers settings, GPS mode, Home lock/Course lock off. Nothing unusual and then - She takes off. Flys like a bat out of hell to my left without me doing a **** thing. Hovers, I try to take control - left, right, up, down nothing is responding. So I throw her into manual mode trying to get anything from it. No response, now she takes off almost out of sight. Ok, time for me to PANIC. Turn off the receiver and pray. ......... She starts to come back a little, then literly makes a circle and takes off again behind a building. Never to be seen again. Guys, I did it all by the book. I took my time, checked everything, know the light signals, am familiar with my area. And it still happend to me. I've been a huge booster to this Quad and my new found hobby. Spent thousands. Met lots of great people and really enjoyed my time here, but this is really depressing. I dont think I can get back into this. These things are clearly faulty with either their NAZA controller, compass or maybe even both. Ive heard to many stories and now Im another one. Im sick about this.
