Hi Everybody,

an you help me telling me how thick and what type of aluminum you are using for the spar, ribs and the structure of the plane?

Most of the RV-7 is made out of 2024 aluminum. The thicknesses vary depending on the structure. Because it's a kit, us builders don't need to pay all that close attention to the materials being used, as they are already provided. Typical skin thickness is 0.032, with some 0.016 (rudder). I think most of the spars are 0.032, with the exception of course being the wing spar which Van's fabricates for us.
