Here's a link to a discussion on dihedral and more, by Roman and Michael Heinrich with suggested guidelines on building & trimming aircraft for flight that I found on SFA (Small Flying Arts)

I thought these would be helpful for those of us building kits, plan bashes and designing our own models.  A place to start from and then progress from there as we develop the models.

I've also copied them to a MSWord doc incase anyone wanted to print it up and stick it on their wall.
