How much weight do you think it would realistically take to alter flight in a plane of this size? For instance, if both the pilot and passenger weighed e.g. 200lbs and sat toward the left of the plane, would that considerably (or perhaps even just perceptibly) impact flight? Same for some of the other variables, is there an appreciable different for things like magnetic variation? Wind, of course, seems reasonable - the others I've heard less about. I don't fly, and have never been in a small engine craft.
