The RV-10 is Van’s Aircraft’s foray into the 4 seat market.  It is a low wing aircraft with fixed tricycle gear.  It has gull wing doors on both sides, and enough room to fit 4 actual people.  It’s really roomy.  It’s construction is riveted aluminum, with the exception of the cabin top which is composite.   It’ll cruise nicely at 160 knots, and it sports a pretty hefty useful load at around 1180 lbs.  Basically, it’s a really nice cross-country cruiser.
