A friend of mine built the kit, I traded for it almost in the ARC form. He was looking to get into the air faster so I traded him an ARF for his CA. I think now he wishes he had kept the CA. I think he was impressed with the kit. It went together quickly for a plane this size. I don't think the manual is very good. You kind of have to know what you are doing to make the manual make any sense. At least that is how I felt about it. With the 105 up front, ign battery on the engine box, rx batteries under the canopy the balance was right in the middle of the range. I didn't have to add any extra weight anywhere. I am running a Hitec 5735 on a pull pull so there are no rudder servos in the tail. I know there are a few other people on here with this plane, and I have never heard any of them post a negative comment about it. I hear that right now Chief Aircraft is selling the CA line with free shipping too. Hope this helps.. good luck!
