I think it might be best to backtrack a bit and simply acknowledge that the RV7 and 9, while having some obvious and numerous similarities might best be treated as COMPLETELY DIFFERENT airplanes, built for very different missions. I know that you were speaking in a specific context but folks can run with a quote in very strange and scary directions.:eek:

The RV7 and 7A are designed for aerobatics and the 9 isn't. Those are very different structural limits. There are MANY other differences including speeds, load limits, weights, including weights at which aerobatics may be performed in the various aerobatic models etc...That question alone has sparked entire threads due to some abiguity about fuel being included or not, and responses from Vans!

No flame intended, just worried about unintended consequences...
