OK thanks for both your inputs on dihedral. I am absorbing all the information I can about this and other topics. I've read this entire thread. and I get both sides of the whole cg debate. As a new builder of RC planes, it really helps me to understand the thinking behind all this. After reading 8 pages of this thread, I've learned at least 2 things. 1.) There are rules about aerodynamics. 2.) These rules are not set in stone and its important to think outside the box or "wing it".(sorry I could not resist)
So thank you Dick Hanson and thank you to all that opposed him.
What, as a new builder, I was expecting to read in the aerodynamics thread were things like: airfoils. body designs, wing shapes etc. I guess I got some of that. I just don't think I need to wade through 8 pages of "I'm right, no I'm right!" to get it.
I think this thread would be more useful to new builders if we could see more testimonials and proven information that has been implemented on real RC planes. Like what has worked, what has not worked, why, and what you would do differently next time.

Rapptor tells me that 2 or 3 degree dihedral has worked for him. Johng tells me that 2 much will hurt ( i don't want my ailerons to be less responsive) and gave me an example of lining up with the centerline . both posts are useful to me. More posts would be even better.

thanks
