Troy is spot on (as usual) with his assessment that CG is very much subjective and in fact all trimming can only be done by seeing how the plane flies. I personally like my CG quite well back as I like the way this makes the planes roll, a friend of mine in our club who also flies pattern sets his planes up with a CG further forward than I like it, to the extent that I don't really enjoy flying his planes and he doesn't like mine.

I read an article a few years back which gave a formula for waorking out a good starting point for the location of the CG, and I was amazed to find it actually works for me. For others such as Troy I suspect it would place it too far back.

However, I don't usually bother to work it out, I fly it and see what happens! And it's worked ok so far.

If anyone wants a copy of the formula let me know, I won't put it here though as it's not terribly easy to enter into this kind of format.
