Hi Gerry, I certainly agree that finding the neutral point first is the way to go and also setting the CG initially at a conservative 20% or so.
In this way, you can tell how much static margin you should have, before reducing that margin to get more aerobatic behavior.
I will not disparage any of the competitors' products. If you are confident in their results, then go ahead and use it. I am just cautioning you that the Neutral point accuracy is critical and some calculators I've seen, do not give the same results as the CG Optimizer, which I know contains very credible analytics. I suggest that you check the www.rcaeronauts.com
site again, for updated information.
Best of luck.
