Hi Steve.
You are right about the Venus II. We've talked about that plane. It is indeed a nice plane, but, since it is a modern classic pattern design, is it "qualified" for SPA? For that matter, is the Spot On 50?
I just checked the SPA "Approved Planes" list and neither are on it. See

They recently added the Skylark 70, though, and that plane will work just fine with the original engines you listed in the original post. One nice thing about any larger aircraft, especially for those of us that are getting senior discounts.. [X(]

is the visibility.
Dick.
