Dick, and the rest of you, I think you're missing the point that anyone that cruises through a few plans and considers what they are looking at is hardly capable of making a true WAG any longer. Rather what they draw will be a distillation of what they have seen before modified to suit what they think they need.

If you do a search around here for a couple of recent threads where some very new modellers are trying out their design skills for the first time you'll see that the airfoils they WAG are crude in the extreme. It's not that they are any less smart than the rest of us but they just have not had their pool of knowledge seasoned with some successful background spices. I'm sure that like myself you and Ben and Paul all had a lot of reading and plan studying of the model mags under our belts before the pencil ever hit that first piece of paper. So a WAG is just not possible under those circumstances. Rather a suitable airfoil that will perform "well enough" is almost always going to be the result.... at least for our model purposes.

So what you are considering to be a WAG is actually a sausage of history wrapped up in a pastry of inspiration with a dab of edcuated guess sprinkled on top.... sorry for the food parables but I'm eating breaky as I type this....
