I used ca hinges on mine and have had no problems! Although I did add an extra hinge as they recommend. Powered by O.S. 1.60FX, used pull/pull on elev. and rudder 2 servo's in each wing. 12.6 lbs. I have one of the newer releases also, laser cut they were able to shave almost a pound off compared to older model. Don't know exactly how many flights on it but no problems what so ever. I did find that they were a little conservative with c.g, I believe that I'm a little past 6".
