I am fairly new to being around RVs and I still have trouble sometimes in being able to tell them apart. So, here are some of the things that I have noticed that you can look for.
Lets start out with the easy one, RV-10:
It has Gull Wing doors, is MUCH larger than any of the other RVs, and it has a roof. It is the only 4 place RV.
The next easy one is the RV-3:
These are a smaller than the RV-4, RV-8, and are the only single seat RV. It has the big puffy "Cheeks" (on the cowl) like the RV-4s, but the canopy is much shorter, as is the rest of the fuselage.
Next are the RV-4 and RV-8, both are tandem two place airplanes. The easiest way to tell them apart is by the roll bar.
The RV-4 has a triangular roll bar in between the two passengers, the RV-8 has a round roll bar in front of the pilot.
Other differences include size, the RV-8 is larger, and the "cheeks", RV-4s have big puffy "cheeks" RV-8s do not.
