Hey guys,
I'm waiting to pick up my Smith project and also waiting for the plans to arrive. From what it looks like the original airfoil has a flat bottom and might be something like a Clark Y.
I went to visit a guy that had the plans for the new Smith version called Smith Miniplane 2000. Well, he gave me the blueprints because he said he would never build one so I brought it home and studied it.
Besides the plans being some of the worst I have ever seen the airfoil on the drawings is the 23013. So far I can't find anybody that has built with this wing.
I know that the airfoil has less drag and a little more lift but what else would change? The stall characteristics should change right? The stall difference between a Cub (usa35-flat bottom) and a Taylorcraft (23012) is noticeable but would it be similar in a biplane?
I'm reading the new version of the plans and it makes me wonder why he would change the airfoil to this.
