Kyle, that is the first time that I've seen them going in that direction, The one I've seen are 90 degrees to yours, parallel to the ribs. They are pretty common on 701s and CH just calls them stiffeners. But I have no idea what is allowed in your country as they are not in my plans. There are pics on the US Zenith site and I believe some in the old Zenair news as well. Almost forgot, the reason I replied, lengthways on the wing like yours is much easier to fabricate, I like it.
