Today at work, I was tongue lashed because I did not provide enough Leading Edge roundness throughout the Wing Leading Edge on the model so, I just got back from the Hobby Store and purchased two sized balsa leading edge sections and will start my re-work soon.
The whole reason for an Airfoil was for lift but, if I do not provide a round enough Leading Edge on the wings all that is thrown away as the air will be disrupted instead of going over the wing in a smooth manner.
I am taking pictures
