questions about CG

hi everyone, i have this wing kit all ready to go and i want to get it right this time. i put the numbers into the CG calculator in inches (in the sticky thread) and got the CG. But now what do i do? What do i do with the CG? And one other thing... when i plug in the numbers and it gives me the CG, is that distance from the nose at the root chord or from the back. My number was 6.5 but from where? What i really really need to know is how do you get the CG right by putting the dang motor at the back and all the battery and servos and other stuff up front?? i always have pitch problems with my wings and they either nose dive or climb straight up. i really want a stable wing this time. Please help. oh and thanks a ton for all the support

is the bays pre cut or how is it done if its not precut move everything far forward as possible that in cludes servos and battery reciver and speed control are the litest they can set in the back better yet go in the build thread called ritewing build thread and read as much as you can and it will explain everything you need to know hope this helps.

You can tape everything down to get a rough idea of where it balances. Usually everything as far forward as possible.

Dont be afraid to add lead. My first TL40 had over 10 oz of lead to balance and she did not lack in any departments.
