I'm building a new ametek based HAWT here, and really want to get this right the first time through.
In a perfect world,
Should the balance point be at the yaw bearing?
How much difference will it make if it's a bit in front of or behind the yaw bearing?
I understand that if it's too far off the yaw bearing will wear quickly, and it might yaw hard or not at all, but will a little difference in balance (maybe an inch or so fore or aft) cause a big performance hit?
