Acro Sport II plans note:
On sheet #2, area A3,B4 there is an easily miss read dimension. The station #4 shown in A3 is drawn as though it is in a vertical plain making the 22" dimension appear to be a vertical dimension. It is not. The 22" is the length of the angled tube from point to point. The 22" tube connects the top longeron at 60 3/4" and the bottom longeron at 55 5/8" from the firewall station.
The latest plans have a note at zone A3 that mentions this.
