I tried posting this in Aerodynamics:

I'm new to the hobby. I've met a group at a local flying field that I'm convinced will help keep me on track. I have sooo many questions.

I've recently made 2 deals here on this site. The first one was for a realitively large glider- a Sailaire, which isn't going to be built until I can confidently fly the one currently being built on my bench- a 2 meter Easy Eagle. And the second was for a JR Tx/Rx: both of these I believe will keep me busy for a while......

The questions I have are with regard to flight characteristics of polyhedral wings. Stable as hell- that part I understand. Most of the glider models with polys (sans ailerons) I've seen sport some very large vertical stabs or vees. As I grow with this sport, I will want to "graduate" to an aileron model. If I constructed a wing with ailerons using the models original wingplan without the polyhedral (well, maybe I would be wise to include some dihedral), would I also have to consider a revised empennage?- with smaller vertical control surfaces? Or are there other factors I should be considering? What about the inclusion of flaps and/or spoilers? If I include these features, should I be considering a different airfoil...?

I read somewhere that putting ailerons on the polyhedral wing of a floater was a waste of time. Could someone explain why?

Comments welcomed.
