I'll answer your points in post 44 when I get some time. But you got most of it right.

As far a classes I seem to get slapped for giving too much detail for the "average pilot". Too many folks think I'm been esoteric at best or arrogant at worse. I hope I give too much detail rather than not enough. You the (OP) are free to use what fits your needs. You will note that as time goes by some will try to say "but but he (you the OP) is sport flier and doesn't need all that detail". True most sport fliers don't need the detail I go into. But those that listen and use what I'm saying usually have that little edge that really improves ones outing at the field even as sport fliers. I'm just trying to help all that ask, get the most from our toy engines. And even some that are closed minded to the competition arena.

As long as you are asking smart (thinking) questions I't try my best to help. Also don't be afraid to ask for a drawing, if you think that will help. As you can see I can be rather verbose. This is odd as I can't spell english worth a damn.

All the best.
