The Arizona 1/4 scale plans I have are the same as the Gary Allen plans from RCM (US mag) They are pretty much identical to the 1/3 scale Arizona plans (except for size) I also have and short kit, I'm currently building. The plans are nicely detailed , traditional build and have all patterns. The 1/4 scale plans are also available here.http://www.airagestore.com/plans/1-4...ngmeister.html
Fiberglass cowl and fenders should still be available.
Hope this helps.
