Tom ,
I have the foam wing and no experience with the scale one.
Anyway the 40' wing doesn't look wrong a bit like on the Yellow A4.

Here is my first attempt at posting a video, thanks for the advices Strykaas!!
If there is interest I can try to post more , this is just the take off.
But with aol I'm limited to 1 meg files....
