Here we have Dennis scratch building, Eric building to plans, Vance with a ready build with weight and balance and limits available and test flown.
Each is a somewhat different situation. Dennis is going to have to do quite a bit in determining his CG and where his safe limits are. Eric hopefully will have the information provided with the plans and provided he does not deviate much will have been completed towards the problem. Vance had to know about the theory of, and how to work the weight and balance sheets provided and remain within the limits that had already been found out. He is of course making major changes now and these will all have to be recalculated, the machine test flown and new limits established.
To my mind rotor aerodynamics are not as simple as fixed wing aerodynamics making it a somewhat more variable and complex problem, but then again I am a beginner in this field, definitely no expert, and may be making more of it that there really is.
Vance sounds as though you and Ed are really enjoying the trip. Hope you have a great time when you get there.
