start out with the control throws recomended in the instructions. then make adjustments to your liking after you have flown it. I started with the recommended CG then slowly moved it rearward to where i like it. I also increased the throws on the control surfaces.( high rate)I'm not sure how much i have. I just kept increasing it to where its real snappy. Then i use lower rates for landing, takeoff ,ect.

I seems that most models have a conservative CG. I guess to make sure novice pilots can fly them without too much trouble. I almost alway move the CG rearward after getting to know the model and its characteristics. But thats just me.
