I didn't spot an RV-3. There is one at Shoreham nearing completion. Here's the two-seat RV-4.

Lots of bright paint jobs like this RV-6.

Odd one out. The RV-6A with a nosewheel.

The lesser-spotted RV-7.
This RV-8 looks a completely different colour from different angles.
It's the one on the left here.

Another RV-8
And an RV-7
