With an AFR or a kit build, it will always come down to how well the model is ASSEMBLED and TRIMED. Some of the ARF'S I have flown have almost taken as long as it would take to assemble a good quality kit. You need to do your home work with an ARF using forums like this to draw on the experience of others to overcome design deffects etc so they will last a long time and you get value for money? time.
