RE: How Can You Tell the difference?
As speedracerntrixie mentioned above, there are many factors involved in the way a particular plane handles. Each and every item has an effect and after changing these various items over time one begins to get a feel for what each does and how they interact with each other. To illustrate, some years back, I spent some time trying to learn to hover and after another pilot that had a plane like mine tried to hover my particular model he commented on how slow my servos seemed. He suggested a chang to a much faster servo and that gave me a more connected or locked in feeling and I immediately noticed a difference in my ability to hover. I could at least hold it for a short time where before I would lose it in seconds. At that time I had been flying RC over forty years but on that day I learned how important it is to have someone assist you that is proficient at whatever you are trying to learn. Of course the preceding is just MHO.
