i hear ( and also read in here) about guys fooling around with moving their C.G. back which makes the plane more responsive to inputs. i was just wondering how this is accomplished. let me say that when i fly a plane for the first time, i try to get the C.G. where it's supposed to be ...i realize this is very important on the first flights with a new model. so....when someone moves the C.G. back....is this done simply by moving the rx and battery aft in the fuse and testing and so on? i wouldnt think adding lead to the tail would be too good of an idea but, who knows. this is what i'm asking. any suggestions? thanks in advance
