I have been flying pattern planes for a few years now and am wanting to design my own onw, there are some questions I need answered first to help with my planning, it's going to be a 2m x 2m job with a YS140/160 up front, fixed landing gear with plug in tail andn wings.

1) can I use a straight forward symetrical aerofoil.
2) Do I need dihedral - if so how much
3) do I need wash out - if so how much
4) is there a set distance between nose to leading edge, and chord lenght, and tailplane position

I understand what all these mean I just don't know how to implement them into a pattern plane so I can have good flying qualties.

If anyone can help that would greatly appreciated
