The way I found easiest to learn how to work with the data logger data is to only look at one line of data at a time. Fly and record a pattern. download the data. The data viewing program, at least CC's, will let you look at only one data line at a time. Getting all the complexity out will let your eye pick up patterns much easier. Start maybe with rpm. You will be able to see each maneuver by the rpm changes. You will be able to see what kind of rpm changes you are getting at various segments of each manever. You will see both acceleration and braking. Make sure the governor is able to keep the same rpm throughout the pattern. If its dropping off at the end, you do not have enough energy for the whole pattern. You will want to go up in battery size either in mah or go to higher voltage by adding another cell. I usually find its easier to go to a larger mah battery if I see this. You can learn a tremendous amount by just looking at the rpm curve. Then pick another curve, maybe amps or voltage to see what is happening with them. When you find one that gives you the most info for what you can understand, change something in your settings and see what kind of difference it makes. For instance you might change the gain on a flight and see what kind of change you see in rpm. Before you fly though, write down a hypothesis as to what you think the gain change is going to do and what you think that might look like on the graph. Then look to see if you were correct. If not, try to determine what you are seeing in that one variable and correlate it to the change. Also note any differences you found in the flight and how it felt. I was very surprised when I did a series of tests on CC & Hubin equipment with what I found and how it correlated to how the plane flew. Don't take anyone's word for it unless they present you with the data and can prove it. "Common knowldege" is not always correct.
Enjoy it! The ability to consistantly fine tune an electric is a huge advantage.
